Spacemen Need to Exercise Harder to Stay Fit in Space
Life for little green men isn’t easy. New findings in The Journal of Applied Physiology reveal astronauts floating around in space need tougher workouts. Typically, astronauts spend six months on an International Space Station and during this time, despite regular exercise, crew members can lose 15% muscle mass and 20% to 30% of muscle performance. Experts say by clinical standards this is a major loss of muscle, prompting them to recommend a balance of high-intensity resistance and aerobic exercise, in order to protect against the effects of a microgravity environment; Newswise reports.
If you’re zipping around in space or just sitting on the couch, exercise is important. According to Dr. Fuhrman staying physically active not only keeps you fit and trim, but improves your psychological function, by reducing stress, anxiety, and depression. And resistance training is very important, in both men and for women it helps bolster bone density, which staves off osteoporosis and bone breaks.
