Repeated Horizontal Jumping is a Feasible Exercise Countermeasure for Microgravity

Astronauts who spend prolonged time in microgravity on the International Space Station can experience a significant reduction physical fitness. Jumping exercises represent potential solution to this problem as European Agency has demonstrated that deconditioning effect of long-term bed-rest be countered with around four minutes per day jumping. The purpose study was evaluate if repeated jumping is possible and transmission impact forces vibration aircraft minimised. Five subjects performed custom jump sled both during parabolic flight campaign normal gravitational conditions. Forces expressed by user transmitted were quantified using bespoke instrumentation system. These results show, for first time, horizontal microgravity, force minimised supine sled. peak effective ground reaction experienced sensitive style used resistance employed. open door next generation exercise countermeasures deep space exploration. In particular, we have qualified High Frequency Impulse Microgravity (HIFIm) device Technology Readiness Level 6 making it leading candidate replace Advanced Resistive Exercise Device (ARED) which been service since 2009.
