Belgrano to Mars
The Antarctic continent is considered to be one of the most realistic analogues found on Earth of the situations of extreme isolation and confinement experienced in space. Since 2014, we have been conducting at the Belgrano II Argentine Antarctic Station the project "Chronobiology of Antarctic Isolation: the use of the Belgrano II Station as a model of biological desynchronization and spatial analogue", also known as “Belgrano to Mars”. The project aims to explore the impact of a year of isolation on different physiological, psychological and social variables. In particular, we are interested in studying how biological rhythms are affected by the lack of natural light during the four months of polar night typical of that latitude. The study of the chronobiological responses to extreme isolation increases our understanding of the physiological mechanisms underlying human biological rhythms, with applications in space exploration or other highly demanding professional settings, as well as in human health.
The Belgrano II Antarctic station consists of a series of scientific research facilities located approximately 1,300 km away from the South Pole at 34°S, 77°W. It is the most southerly Argentinian station and one of the three southernmost permanent stations on the planet. The temperature ranges from 5°C to 48°C below zero. One feature of this station is that, due to its latitude, it has four months of continuous sunlight, four months of twilight and four months of polar night. The station crew is composed of around 20 men. To generate a light-dark cycle during the summer, windows with blinds closed are used, in accordance with a normal sleep routine, while using eye covers during the night if necessary. Exposure to ultraviolet light is also stronger and sunglasses for external work are mandatory. Conversely, in the wintertime, the light-dark cycle depends entirely on artificial light. Schedules with well-defined times for meals (breakfast, lunch and dinner) work and rest are paramount in Antarctic stations.
“Belgrano to Mars” is a collaborative project in which researchers Camila Tortello and Santiago Plano (UCA-CONICET and UNQ) participate in the analysis and interpretation of the information and Juan Manuel Cuiuli (Joint Antarctic Command) in the scientific coordination between Buenos Aires and Antarctica. Other members of the project are Marta Barbarito (Argentine Antarctic Institute), Diego Golombek and Patricia Agostino (UNQ and CONICET), Agustín Folgueira and Juan Manuel López (Central Military Hospital), and Guido Simonelli (University of Montreal). Field work during isolation is carried out by physicians from the wintering crews at the station and staff members that volunteer for the study. Antarctic scientific activity is coordinated by the National Antarctic Directorate (DNA), which together with the Joint Antarctic Command, provides the logistics of the bases.
This year, we have traveled to Antarctica to supervise the implementation of the Belgrano to Mars project in the field, to test measurement instruments and to train the crew in the use of the equipment and software. The trip demanded six weeks of navigation in the ARA Almirante Iríza icebreaker. In addition, we started working with the European Space Agency (ESA) in the operational test of the Telemedecine Tempus Pro equipment, under the framework of an ESA-CONAE-DNA agreement. The project, led by Dr. Víctor Demaría-Pesce, from ESA's European Astronaut Center, involves conducting operational simulations in a situation of extreme isolation and confinement, which will contribute to the design of a definitive prototype to be used by astronauts and medical teams during future space missions to the Moon and Mars. The equipment will be tested at Belgrano II (Dr. Bruno Cauda and Enf. Luis Almaraz) and Carlini (Dra. Melina D'Angelo and Enf. Gustavo Cruz) stations, through six simulations that will recreate medical scenarios similar to those encountered by astronauts in space.
Lessons to be learned from this kind of study
We have recently published in the journal Scientific Reports (from the Nature Group) data regarding changes in the sleep-wake cycle during a winter campaign at Belgrano II. We observed that during the polar night the subjects tended to go to bed one hour later and sleep one hour less. A possible explanation is that this is due to the lack of exposure to natural light, since bright light acts as a synchronizer of our biological rhythms. This loss of sleep was somewhat compensated by naps, which were longer during that time of year.
These results show us how biological rhythms can be desynchronized in periods of prolonged confinement, such as the ones we have had to go through during the quarantine periods instituted in different countries. Moreover, it highlights the importance of exposure to natural light in the morning and darkness during the night and maintaining fixed activity and rest routines to avoid the desynchronization of our biological rhythms. Other sleep hygiene measures include the limiting of daytime naps to 30 minutes, regularly exercising (it may be necessary to avoid working out before bedtime), having a light dinner, avoiding stimulants like caffeine and nicotine close to bedtime, and making sure that the sleep environment is dark, silent and with a pleasant temperature. The beneficial effects of having good sleep relate to an increase in alertness during the day, the prevention of anxiety or depression, and the improvement of our general health, which in turn will reduce the chances of becoming ill.

With our tagline of Space Without Borders, we at InnovaSpace love to hear about space initiatives happening in countries where space activity is less expected, so we were delighted to hear from colleagues in Nepal about the construction of the first fully Nepal-made pico-satellite. The satellite in question, called SanoSat-1 (sano means small in Nepalese), is the work of an enthusiastic group of students, engineers, and amateur radio operators from the country, who have been working since 2017 on the design and construction of this tiny pico-satellite, weighing just 250 grams and measuring 5x5x5 cubic centimetres.
Take a look at the video below to see what they have been creating. The team will launch the pico-satellite into space in December 2020, onboard a SpaceX Falcon 9 rocket, and are currently fund raising to cover the launch costs. Check out their GoFundMe page and contribute a little if you can to help Nepal take another step along the path to being a space faring nation!

Successful International Baccalaureate Diploma candidate; Ketedralskolan, Linköping, Sweden & now studying medicine
For as long as I can remember, I have always been flying around. My mother was a flight attendant, my father was an Air Force mechanic and we spent most of our lives living in an Air Force base. To board, deplane and wake up with the noise of helicopters and jets was part of the routine, which did not make it less special to me.
When I was 17 years-old, my family was transferred to Sweden and I had to decide what I wanted to do with my life. I was only sure about 2 things: I wanted to help and serve people, and I loved airplanes and the life in the air. How was I supposed to combine these two? I had no idea. Most people did not see a link between these two points, but I knew that I had to find a way, otherwise, I would never feel complete. If I would imagine myself permanently away from jets and airports or not in direct contact with people in need, a huge void would open in my chest; it just was not right, “either, or” was not an option to me.
In a Spring afternoon of 2018, I overheard some fighter pilots telling stories about accidents they had witnessed: a smashed jaw during the ejection after a period of temporal distortion, tunnelled vision, and a total blackout during the centrifuge training. Then, it hit me, those people were the link, they were the ones who connected those amazing machines to the human factor, they were the ones I wanted to help.
I started to research, and I still remember the first words that caught my eyes: “flight-surgeon”, “AsMA”, “Aerospace Medicine”. Upon reading the last mentioned, my heart dropped. I had found it. I had found an entire field and community of people as curious as me and that shared the same passions. And at the end of that year I was given the chance to get in touch with it more directly.
To graduate the International Baccalaureate (a different kind of high school), every student must carry out an independent research about a topic they would be interested in studying in university, our first research paper. I knew exactly what I wanted to do, I wanted to understand the symptoms and episodes I had heard about countless times, I wanted to understand what that so feared G. was. I read all the books about aerospace medicine fundamentals and flight physiology I could find, I started to talk to every single crew member and engineer I could reach, but the understanding of the symptoms through medical lenses was still missing. Another important thing that was missing was a supervisor, who would be willing to help me to start the research. Basically, the Science Department of my school did not understand what I was going for, how I was going to do it and no teacher was exactly thrilled with the idea of supervising a student they had no idea of how to help. It was even hard to decide whether to classify it as a Biology or Physics project!
It was in the spring of 2019 that Maria, who was not even my teacher, heard about the project and was willing to supervise me, but I would have to find help from doctors outside; as she put it “You have chosen a very, very specific topic, so you need a very specific knowledge because I can’t tell you how to start”. And here we go again on another quest for a supervisor. And this quest is what made me fall completely in love with the scientific community.
Doctors who had never met me sent me PDFs and articles and two of them (thank you so much, Dr Suto and Dr Lia) sent me the contact of Dr Thais Russomano, who was the fairy godmother of my Extended Essay. She taught me how to structure and organise a research based on the study of the literature, how to select it, how to understand the state of the art of that field. It was more challenging than I was expecting but it made all the difference. Thanks to all her feedbacks and articles I was finally able to understand where I was and how far I would be able to go (unfortunately not as far as I wanted due to school limitations). But now I knew what I was doing. I wanted to understand the effects of the G-acceleration on the human cardiac system and how the Anti-G Straining Manoeuvre diminished its effects. All I needed for the school to approve it was: at least 7 volunteer pilots with enough availability to measure their blood pressure while doing loops 2 or 3 times for a random girl’s school project, piece of cake right?
To my heart-stopping surprise I got all of them, and they were all mostly glad to help me and to send me papers, videos, and pictures from their own centrifuge trainings (thank you so much Major Forneas and Colonel Leite). Nevertheless, to my despair the data collected contradicted my primary hypothesis! Great!
That is when my dear friend Jonas comes into scene. He worked at SAAB, the company which was developing the new Brazilian Grippen, state-of-the-art fighter jet, and offered to arrange me an interview with a test-pilot. It was by far, one of the greatest days of my life!
While we were waiting for Andreas to finish his debriefing, Jonas took me on a tour around the Flight Test Centre. I had always wanted to see the Grippen; only one was ready so far, it had flown only once and only authorised personal could see or get close to it, or at least I had been told. Jonas opened the hangar’s door and there it was! The mysterious Grippen and I was one of the few civils, who had nothing to do with the project whatsoever, who had been able not only to see it but to climb up to its cockpit! Right there, I knew I had made the right choice.
Andreas, the test-pilot, still wearing his anti-G suit, spent a long time answering my endless questions, and by the time I finished the interview I understood where I had gone wrong and the kind of data that I needed to prove my new hypothesis right! And again, I was mesmerised by how the scientific community mobilised itself to help an enthusiast like me, who was still not even part of it.

A pandemia de COVID-19 gerou a necessidade de utilizar medidas de distanciamento social para que haja a redução da disseminação do novo coronavírus. Contudo, têm-se percebido prejuízos na saúde física e mental dos indivíduos, porque a mudança brusca na rotina resultou em um novo estilo de vida das pessoas, que passaram a viver em confinamento. Aumento de preocupações, ansiedade, tristeza prolongada e sedentarismo são algumas das consequências ocasionadas ou agravadas pelo isolamento.
Como forma de minorar esses efeitos, o exercício físico continua sendo reconhecido como uma estratégia não-medicamentosa eficaz que auxilia na prevenção e no tratamento de doenças físicas, metabólicas e/ou psicológicas. Entretanto, a suspensão e a limitação do uso de estabelecimentos, como academias de ginástica e clubes esportivos, para evitar aglomeração, levaram muitas pessoas a praticar atividades físicas regulares em casa.
Nesse contexto, percebeu-se um fenômeno interessante na internet, que foi o aumento da busca por informações online. O Google Trends, por exemplo, é um recurso que expõe os termos mais pesquisados em diferentes lugares do mundo e revela sua popularidade em uma escala de 0 a 100. Nele, foi possível identificar o aumento da busca por informações relacionadas às consequências e necessidades geradas pela pandemia. Nesse contexto, vimos que, no Brasil, as buscas pelo termo “exercício físico em casa”, em Português, antes de março de 2020, teve popularidade baixa (oscilando na escala entre 0% e 25% de procura via Google). Após esse mês, quando se iniciou o distanciamento social no país, a busca pelo termo oscilou, aproximadamente, entre 40% e 100% até o momento atual. Ao analisar o termo “physical exercise at home”, em Inglês, notou-se que, em janeiro de 2020, as buscas estavam entre 0% e 25%. De fevereiro até maio deste ano, as buscas estiveram entre 25% e 100%, diminuindo em junho, momento em que vários países afrouxaram as regras de isolamento. Ao observar esses dados, notamos um aumento considerável na popularidade dos termos durante esse período, demonstrando um maior interesse de internautas sobre o assunto. Essas oscilações parecem ter relação com o fechamento e abertura de comércio e demais atividades no mundo.
Interessante também mencionar a necessidade de adaptar os exercícios a ser realizados em casa. Dessa forma, percebeu-se que o interesse por equipamentos esportivos para realizar exercícios físicos em casa também aumentou, sendo demonstrado nas buscas no Google. A pesquisa pelo termo “equipamentos para atividade física”, nos dois primeiros meses desse ano, estava próxima a zero em níveis de interesse; já em março, o interesse aumentou bastante, chegando a atingir 100 no mês de abril. Em todo mundo, o termo “equipment for physical activity”, pesquisado na língua inglesa, mostrou pico de interesse (100 na escala) no mês de fevereiro e menor interesse próximo ao início de junho (0 na escala). Como a pandemia ainda não está controlada, inclusive com previsão de novas ondas de contágios e mortes, é bem provável que os hábitos das pessoas mudem, realmente, como forma de adaptação à nova realidade.
Apesar da reconhecida resiliência das pessoas, não se pode negar que os prejuízos psicológicos são evidentes e, muitas vezes, é até difícil entender esses sentimentos e lidar com a magnitude que podem atingir. Pensando nisso, repetimos o processo de investigação no Google Trends e verificamos que o termo “depressão na quarentena” não apresentava interesse da população Brasileira entre janeiro e início de março (0 na escala) – esse desinteresse deve-se, provavelmente, ao fato de que ainda não existia o confinamento social no Brasil. Porém, a partir de março, a busca pelo termo cresceu muito, atingindo o pico de pesquisa (100 na escala) no início do mês de maio. Quando pesquisado, em Inglês, o termo “quarentine depression” também não houve interesse pela população mundial entre os meses de janeiro até o início de março. A partir daí, iniciou-se um aumento exponencial pela procura do termo, atingindo seu pico no mês de abril e, após, uma sequente diminuição até o mês de junho.
Do espaço ao COVID-19: o que podemos aprender? Astronautas devem saber lidar com o confinamento e, apesar de serem submetidos a diversos tipos de treinamento para cumprir de forma adequada as missões espaciais, efeitos psicológicos provocados pelo confinamento são relatados na literatura. No caso da COVID-19, não houve preparo para essa nova realidade. Estamos todos tentando desenvolver mecanismos para desenvolver resiliência e melhor lidarmos com a pandemia e todos os acontecimentos relacionados à ela. A internet torna-se uma aliada, uma companhia provedora de informações e possibilidades de compras para as pessoas. O desafio agora é lidar com essa quantidade de informações, separando-as em relação à veracidade e à aplicabilidade.
THE INTERNET, PHYSICAL EXERCISE AND DEPRESSION: WHAT IS THE RELATIONSHIP DURING THE COVID-19 PANDEMIC?

The COVID-19 pandemic has generated the need to employ social distancing measures to reduce the spread of the new coronavirus. However, negative effects on the physical and mental health of individuals have been noted, as the sudden change in routine has resulted in a new lifestyle for people, who are now spending their lives in confinement. Increased worries, anxiety, prolonged sadness and inactivity are some of the consequences caused or aggravated by isolation.
Physical exercise continues to be recognised as an effective non-medication strategy that is useful for mitigating these effects, as it helps in the prevention and treatment of physical, metabolic and/or psychological diseases. However, measures taken to suspend and limit the use of establishments, such as gyms and sports clubs, to avoid people gathering together, have led to many people undertaking regular physical activities within the home.
In this context, an interesting phenomenon has been seen on the internet, which is an increase in the search for information online. Google Trends, for example, is a resource reporting the most searched terms in different locations of the world and reveals the popularity of these terms on a scale of 0 to 100. It was possible from this to identify an increased search for information related to the consequences of the pandemic and the needs it has generated. It can be seen that in Brazil, prior to March 2020, searches for the term in Portuguese “exercício físico em casa” had low popularity (fluctuating between 0% and 25% on the scale of Google searches). The following month, after the beginning of social distancing within the country, the search for this term has varied between approximately 40% and 100% until the present day. When analysing the same term in English, it was seen that interest in this search varied between 0% and 25% in January 2020, whereas, from February until May of this year, searches rose to between 25% and 100%, before decreasing in June after several countries had relaxed their isolation rules. Analysis of this data evidenced a considerable increase in the popularity of the term during this period, demonstrating a greater interest in the subject by Internet users. These variations seem to be linked to the closing and opening of trade and other activities around the world.
It is also interesting to mention the need to adapt to performing exercise at home. Consequently, it was noticed that interest in the sports equipment needed to practice physical exercise at home also increased, being demonstrated by searches on Google. The search for the term in Portuguese "equipamentos para atividade física" in the first two months of 2020 was close to zero in interest levels; by March interest had increased a lot, reaching 100 in April. From a global perspective, the term “equipment for physical activity”, researched in the English language showed a peak of interest (100 on the scale) in February and less interest by the beginning of June (0 on the scale). As the pandemic is not yet under control, and indeed with the prediction of new waves of contagions and deaths, it is very likely that people's habits will really change as a way of adapting to the new reality.
While recognising that people are in general resilient, it cannot be denied that psychological damage is evident, and it is often even difficult to understand and deal with the magnitude of the feelings that may arise. With this in mind, we repeated the research process on Google Trends with the term in Portuguese “depressão na quarentena”, and found little interest from the Brazilian population between January and early March (0 on the scale), probably due to the fact that social confinement did not exist in Brazil at that time. However, from March onwards, the search for the term grew a lot, reaching a peak in searches (100 on the scale) by the beginning of May. Similarly, when researching the term “quarantine depression” in English, there was little interest in the world population between the months of January until early March, with a subsequent exponential increase in searches for the term, reaching a peak in April, followed by a decrease until the month of June.
From Space to COVID-19: what can we learn? Astronauts need to know how to deal with confinement and, despite being submitted to various forms of training to adequately meet the challenges of space missions, psychological effects caused by confinement have already been reported in the literature. In the case of COVID-19, there was no preparation for this new reality, leaving us all trying to develop mechanisms to become more resilient to and cope better with the pandemic and all the events related to it. The Internet has become an ally, a service that provides information and shopping possibilities for people. The challenge now is to deal well with this volume of information, dividing it up in terms of what is true and what is applicable.
Ever fancied spending some time in Antarctica? If so, take a look through the writings of Dr Stijn Thoolen, an ESA-sponsored medical doctor spending 12 months at the Concordia research station. His photos will either inspire you to go do it, or remind you of how desolate and EXTREMELY cold it is! Do take a look at Part 1, Part 2, and Part 3 of his blog series, talking about his time at the world's southernmost continent.

It is a beautiful summer day. There is even less wind than usual (with constant summer temperatures, almost always a blue sky and few weather changes, we are mainly concerned with wind), so I am not afraid to go outside in my t-shirt today. The sun reflecting off the snow is attacking me from all directions, and I will most probably burn, but I don’t care. It may be my only chance this year (and I imagine that in a few months I will look back on this day just like you must now look back at those days at the beach, or under the green trees, in the warm sun…).
It is busy in front of the station. To the left, an empty rack is being carried away, to the right boxes are sorted, behind me a human chain is carrying them away into a container, and in front of me the green “Merlot” hoists the heaviest stuff. The chaos has something of a busy market on the village square (but then just a little different). Everyone is helping to organize those few 1000 kilos of food brought in by the overland traverse. It had arrived here yesterday, finally, after a day or ten on the ice. Huge logistics. You could say that all that food has arrived just in time, after that monstrous New Year’s Eve dinner two days ago (never seen so much food, not enjoyable anymore). But now that I see with my own eyes what is being stored in those containers and in the station, I am confident we won’t starve this winter.
Summer feels like one big party. I have installed myself in the ESA lab by now, as well as within our DC16 crew, who are all still happy to participate in the biomedical research projects (the ESA lab is also a party). Every few days another plane comes in to deliver a new load of guests or equipment, and pick up old ones. Nobody lives here permanently (although some are almost considered part of the furniture after too many summer campaigns). We are all guests, and we are all working towards one common goal: knowledge.
There are currently around 70 people here at Concordia, a beautiful collection of the most diverse backgrounds but with that same goal, and all of us equally idiot to think that Antarctica is interesting enough to leave the comfort of home for. Seismologists, carpenters, glaciologists, climatologists, electricians, mechanics, meteorologists, astronomers, plumbers, physicists, physicians, cooks, ICT specialists, a cleaner, and a station leader. It makes for a lively experience and ensures that there is plenty to discover besides writing blog posts.

In 1666, while self-isolating at his manor house in Woolsthorpe, Lincolnshire due to the Great Plague, Sir Isaac Newton proved, using a prism, that white light was actually formed of a composition of different colours.
Centuries later, Barry Ressler (Founder, President & CEO of Star Associates Inc. & CEO of ISMC Inc.) was running a series of Monochromatic UV germicidal experiments when, by chance, he also created some fascinating colourful images. He placed a data DVD near a window covered by a shade during the exposures for the experiment he was conducting. On the top of the DVD, Ressler placed a prism and a quartz spacer. When the shade was opened, the angle of the rays of the sun onto the DVD surface reflected through the prism and quartz onto a wall, resulting in the astonishing creation of Image 1.
When light moves from one medium to another, some rays reflect or bounce back within an object made of glass or a quartz-like material. This was clearly demonstrated by his experiment, which showed the behaviour of light as the rays bounced around the room to reveal the proper wavelength of different colours of light in the visible light spectrum.
Ressler captured the beauty of these interesting images using a digital 16MP Hasselblad "V" system with 50mm lens. The pictures also showed another interesting property of the quartz, as it can make one side of the object look like a mirror.
This is seen in Image 2, in which the red at the top of the quartz appears because of this mirror effect, reflecting the red from the base off the top of the quartz, while also refracting or bending the light to create the curved shape that can be seen.
And Image 3 is such a thing of beauty, where you can almost pick out all of the colours of the visible spectrum of light, which have been memorised in the correct order by school children of many generations, using the well-known mnemonic – ROYGBIV – for example, richard-of-york-gave-battle-in-vain, signifying the colours in order: red, orange, yellow, green, blue, indigo, violet.
Barry Ressler confessed though that the images happened completely by chance, as he placed the prism and quartz spacer inadvertently on top of the data DVD.
A fortunate case of serendipity that led to some stunning photos, and a not uncommon happening in the world of invention and discovery, whereby a little ‘luck’ or an ‘accident’ has led to an addition to the scientific knowledge. Just imagine if Dr Wilhelm Roentgen, Professor of Physics in Wurzburg, Bavaria, had not ‘accidently’ discovered X-rays while testing whether cathode rays could pass through glass! The first X-ray image ever was of his wife's hand, complete with ring, and his invention led him to become the first ever winner of the Nobel Prize in Physics in 1901.
The three prism and light images used in this blog, with the kind permission of Barry Ressler, first appeared and remain to this day on the American Physical Society Site - Physics Central, where the photos have met with a good deal of interest.
Hello, my name is Helena. In my free time, I enjoy practicing aerial silks. Now, you might ask, “why would you consider this defying gravity?” Well, gravity is almost always used when doing silks. When you do drops, you are using gravity in every way. But there are some cases where you wrap yourself in something I call a friction wrap. This is where you wrap yourself in a way where most people think you would just fall. No knots and nothing exactly holding you. But in real life, you are creating so much friction on the fabric that it almost gives up. There are so many places that there is such a massive amount of friction that it can hold your entire body weight up. This sounds and feels almost like you are defying gravity.
Now, although it might sound like it, the aerial silks don’t rely fully on friction and gravity to help you. A lot of it is also strength and grip. To get into many of these wraps, you have to hold yourself up and even do movements by holding yourself by gripping onto the fabrics and staying there for several seconds. For example, for the “hip key”, you have to hang on the fabric using the grip of your hands and do a windmill movement with your legs to be able to get into it. When you are learning these movements, you are essentially hanging on to the silks for dear life hoping you can finish the leg movements and wraps before your grip gives out and you fall to the floor. Obviously, when you get the hang of the aerial silks, you have a very good grip from doing so many exercises to engage your grip. This is a way gravity works against you.
In conclusion, I hope that after reading some of my explanations and watching my video, you have a greater understanding and respect for the ways that gravity can work against you, but it can also be a great help when you use it correctly in the aerial silks. I hope this inspires more amazement in the art of aerial silks and other forms of circus arts and performing, and shows how complicated and precise that the aerial silks are, and the performers have to be while performing it!
We hope you enjoy Part 3 of the blog by Dr Stijn Thoolen, an ESA-sponsored medical doctor who is spending 12 months at the Concordia research station in Antarctica conducting experiments.

The end of our world is full of surprises…
November 13, 2019, East-Antarctic plateau
My arm has gotten tired now of wiping the freshly formed ice from my airplane window every two minutes, but I am too excited to stop. I almost can’t believe it. Everywhere I look is ice. We have been flying over this ice sheet at 5000 meters altitude for about three hours now, with just nothing at all on the horizon. Completely nothing. And even the horizon seems to disappear at times, thanks to the surrealistic way in which the ever-present sunlight melts the white clouds and the ice together. An endless, motionless ocean of ice, that almost makes us disappear as well. I am just wondering if the pilots have a better idea of where we are, when suddenly two familiar towers appear in the distance. Concordia! My new home! And if I already had any expectations from all those preparations of the last months (years), they were now considerably exceeded for sure. What a special and bizarre place, on the middle of that ice sheet, out of nothing: that people live here!
Can you really prepare for a journey to the end of the world? I just hope that all those efforts of the past months haven’t been for nothing, but with all these surprises the past few days I am starting to doubt it. Since our arrival in Christchurch, New Zealand three days earlier it all went so terribly fast again. We hadn’t even left the airport yet, badly jetlagged and craving for a nice bed, when the IPEV/PNRA reception committee cheerfully told us that our next flight to Mario Zucchelli station was taking off sooner due to rising katabatic winds (I had to look it up as well). Here is your bag with polar gear, the key of your hotel room which you will never use, briefing in two hours, boarding in four, good luck!

When faced with the COVID-19 global pandemic, a reduction in the numbers of people circulating is essential. It’s important to know there are differences between social distancing, isolation, quarantine and total lockdown, however, all of these strategies have one goal in common, which is to contain the speed at which the virus spreads and limit the collapse of health systems. In extended social distancing, those establishments considered to be non-essential are closed to avoid the gathering together of people, while in selective social distancing, people belonging to at-risk groups, especially the elderly, are encouraged to stay at home. In isolation, sick people (with suspected or confirmed disease) are separated from the non-sick, whether in a domestic or hospital environment. Quarantine is carried out by those people who have come into contact with or are suspected of having come into contact with the virus and, even if not presenting symptoms, they are isolated from others. When none of these measures work, a total lockdown is declared, like a community quarantine.
Although essential, staying at home involves a radical change in the habits of a population, which may harm health in some way. Within the context of epidemiological normality, work, academic and leisure activities require a variety of effort that, taken together, maintain the minimum level of daily physical activity necessary for health, especially for sedentary individuals. An immediate interruption of these activities has a negative impact on the cardiorespiratory and muscle systems, responsible for maintaining functional capacity. This, in turn, is directly related to quality of life and the development of comorbidities.
Similarly, and at the same time, physically active individuals are compelled to abruptly interrupt their exercise routines during this period. The damage caused by this halt in training includes losses in muscle strength and mass, aerobic capacity, and joint flexibility and mobility, in addition to alterations in body composition. The change from a physically active to sedentary life can affect important variables for health maintenance, including blood pressure, blood glucose and cholesterol levels.
It is therefore advisable to use countermeasure strategies to combat the disuse. One of these is the practice of exercise - known to be the best non-drug health promotion strategy. The American College of Sports Medicine (ACSM) has already taken a position on the importance of staying physically active during isolation. The weekly recommendation for asymptomatic individuals is 150 to 300 minutes of aerobic exercise, plus two strength training sessions. One could, for example, do 5 workouts a week of 30 to 60 minutes, adding muscle strengthening exercises to two of them. The intensity should be moderate, as very light stimuli may not promote benefits, while very high intensities are associated with impaired immunity.
Although many people doubt the feasibility and efficiency of home training, the literature shows that results similar to those obtained in traditional gyms can be achieved by using one's own bodyweight as a load. Routines can include exercises based on calisthenics, both in aerobic (stationary running, climbing stairs, jumping jacks) and strength (squats, push-ups, planks) training. Accessible materials can help: elastic bands, skipping ropes, and even household items to increase the workload (water bottles, backpacks with books, bags with groceries).
