Penguin suit is developed as an anti- g suit in Russia.
Resistive exercise consisted of knee extension and flexion exercise for the last 15 min of each hour while in a supine position in a bed. Single skinned muscle fibers were prepared from the bundles of biopsy s samples. Long-term muscular inactivity induced alterations in contractile properties of human skeletal muscles. Resistive exercise with the stretch of calf posterior muscles by wearing a Penguin suit prevented alterations of contractile properties, but not without the stretch.
