Abstract

Primates appeared to be a good model for investigating muscle contractile and biochemical properties, as well as EMG recordings. The purpose of our study was to examine the effects of microgravity on the contractile properties of the slow-type triceps and fast-type biceps muscles during the 14-day Bion 11 spaceflight.
