In a now-infamous exchange, Sally Ride, who in 1983 became the first American woman to go to space, said she was asked by engineers if 100 tampons would be enough for a one-week mission ...
In a weightless environment, astronauts put almost no weight on the back muscles or leg muscles used for standing up. Those muscles then start to weaken and eventually get smaller. Consequently, some muscles atrophy rapidly, and without regular exercise astronauts can lose up to 20% of their muscle mass in just 5 to 11 days. [67]
Calf muscle strength was measured before and on days 2, 8, and 12 of spaceflight and bed rest as well as on days 2 and 8 after spaceflight and bed rest in the two investigations. Muscle biopsies were obtained before and within 3 hours after spaceflight (m. gastrocnemius and m. soleus) and bed rest (m. soleus) just before reloading.
This is known as the "Fitness for Duty Standards". Space crews' current nominal number of work hours is 6.5 hours per day, and weekly work time should not exceed 48 hours. NASA defines critical workload overload for a space flight crew as 10-hour work days for 3 days per work week, or more than 60 hours per week (NASA STD-3001, Vol. 1 [11]).

Although most early measurements of the amount of bone loss were not reliable, they did show bone loss in Gemini, Soyuz 9, Apollo, Skylab, Salyut 7, Mir, and the International Space Station. [3] William E. Thornton, an astronaut and physician, was one of the biggest proponents of exercise as a way of preventing bone loss. [4]
