Abstract Experiments have been performed in skeletal muscle fibres from the lateral head of gastrocnemius muscle of female rats. Changes in intramuscular calcium movements due to microgravity conditions have been tested by tension measurements in chemically skinned muscle fibres. Our results show that microgravity induces i) a decrease in maximal muscle strength developped by contractile proteins ii) a decrease of intensity and rate of both Ca release and Ca uptake by the sarcoplasmic reticulum.
