Sex Differences in Response to Maximal Eccentric Exercise

In response to eccentric exercise, women experienced greater immediate strength loss than men and were more likely to be high responders for immediate strength loss; men experienced greater serum CK activity than women and were more likely to be high responders for increased serum CK. Although the explanation for high responders to eccentric exercise remains unknown, we have shown that there are sex-specific differences in CK and strength-loss response after eccentric exercise.
