Counteractivity
NASA has employed exercises and procedures known as countermeasures that prevent the risks microgravity entails. Preflight countermeasures highlight the physical fitness while inflight countermeasures highlight nutritional provisions and exercise apparti. Postflight involves rehabilitation of astronauts physically and mentally.
Resistive Exercise
Strength training or exercise against a load is done inflight to prevent skeletal and muscular atrophy. A new strength training apparatus called he Advanced Resistive Exercise Device (ARED) will be available on the International Space Station (ISS) in fall 2009. The new device can put loads of 0-600 pounds.
Cycle Ergometer
Astronauts literally use a special space bike machine to train the cardiovascular system before space walks and to keep the body vital. The bike device can be set for pedal speeds up to 120 rate per minute.
Treadmill Exercises
Astronauts use a treadmill to train on for cardiovascular endurance and to keep the body adapted to walking on planetary surfaces. It also helps deter bone deterioration. The user is restrained in a harness and has weight bearing devices on them. The newest treadmill (T2) will have advanced sensors to give an exercising astronaut more data on their workout. The T2 will be on the ISS in fall 2009.
