Detailed explanation-1: -It ensured spacecraft would avoid being pulled into the Sun. Scientists noted that muscles and bones would need physical stress to remain healthy during manned space flights.
Detailed explanation-2: -The only way to minimize muscle atrophy in space is through intensive exercise, particularly strength training exercises, combined with an adequate diet. Astronauts on the International Space Station spend 2 1/2 hours per day exercising to combat the effects of muscle atrophy.
Detailed explanation-3: -In the microgravity environment aboard the orbiting International Space Station, bones and muscles don’t have to support the body’s mass (weight on Earth). Without Earth-like exercise, astronauts would experience bone and muscle loss or atrophy during their stays in space.
Detailed explanation-4: -Astronauts should exercise for two or more hours a day, several days a week to minimize the effects of microgravity on bones. High-intensity resistance workouts have proven to be effective against bone loss, both in microgravity and on Earth.
