Vesoljsko smučanje za zdravje

Tehnologija omogoča, da je v tem stoletju človek ves čas prisoten tudi v vesolju, vendar z neželjenimi posledicami breztežnosti, zaradi katerih ima ob vrnitvi na Zemljo lahko velike težave. V vesolju astronavti sicer izvajajo dnevno vadbo, vendar kljub temu izgubljajo kostno in mišično maso, zlasti v nogah, nastanejo pa tudi spremembe v srčnožilnem sistemu. Zato za prihodnje vesoljske misije razvijamo opremo in strategije telesne vadbe – protiukrepe, s katerimi bi ohranili zdravje astronavtov, kar bo še posebej pomembno med dolgim potovanjem na Mars. Trenutno je najboj optimalna vadba tista, ki simulira smučanje. S kolegi z Univerze v Ljubljani (Medicinska fakulteta in Fakulteta za šport), slovenskimi podjetji in raziskovalnimi ekipami z vsega sveta raziskujemo, kako učinkuje ta novi vadbeni protiukrep – vesoljsko smučanje. Ni naključje, da razvijamo in proučujemo vesoljsko smučanje prav v Planici, svetovnem centru smučarskih poletov. V predavanju bom predstavil simulacijo vesoljskega smučanja in rezultate tega treninga.

Space skiing for health

Technological advances have enabled humans to have a permanent presence in space in this century, but with unwanted consequences of weightlessness, which can be dangerous on return to Earth. Despite current exercise methods, astronauts suffer a loss of muscle and bone mass and cardiovascular deconditioning. In preparation for deep space missions, we are developing and assessing exercise equipment and strategies – countermeasures that can help preserve astronaut health during missions to Mars. Currently, the most optimal form of exercise is one that simulates skiing. Together with colleagues from the University of Ljubljana (Faculties of Medicine and Sport), Slovene companies and science teams from around the world, we are investigating the effectiveness of this novel exercise countermeasure – space skiing. It is appropriate that the development of space skiing is taking place in Planica, the world centre of ski flying. In my talk, I will present how we simulate space skiing and our results of space ski training.
