Key result
During nonischemic static exercise, women demonstrated attenuated increases in muscle sympathetic nerve activity compared with men, despite similar maximal voluntary contraction (4.0 vs 4.3 kg).

Does gender influence sympathetic nerve responses to static exercise in untrained adults?
Women exhibit an attenuated sympathetic neural outflow and metaboreflex during nonischemic static exercise compared to men, independent of muscle mass or workload.
Ettinger et al. (1996) conducted a cross-sectional in Healthy untrained adults (n=62). Static exercise (handgrip and adductor pollicus) vs. Men was evaluated on Reflex responses to static exercise (blood pressure and muscle sympathetic nerve activity). During nonischemic static exercise, women demonstrated attenuated increases in muscle sympathetic nerve activity compared with men, despite similar maximal voluntary contraction (4.0 vs 4.3 kg).
