We tested the hypothesis that muscle sympathetic nerve activity (MSNA) would be higher in endurance trained (ET) compared with sedentary men with similar levels of total body and abdominal adiposity. We further hypothesized that sympathetic baroreflex gain would be augmented in ET compared with SED men independent of the level of adiposity. To address this, we measured MSNA (via microneurography), sympathetic and vagal baroreflex responses (the modified Oxford technique), body composition (dual energy x-ray absorptiometry), and waist circumference (Gulick tape) in SED (n=22) and ET men (n=8). The ET men were also compared to a subgroup of SED men (n=6) with similar levels of total body and abdominal adiposity. Basal MSNA was greater in the ET compared with SED men with similar levels of total body and abdominal adiposity (28±2.0 vs. 21±2.0 bursts/min, P<0.05) but similar to the larger group of SED men (n=22) with higher total body and abdominal adiposity (vs. 26±3 bursts/min, P>0.05). In contrast to our hypothesis, sympathetic baroreflex gain was lower in the ET compared with SED men (-6.4±0.8 vs. -8.4±0.4 aiu/beat/mmHg, P<0.05) regardless of the level of adiposity. Taken together, the results of the present study suggest that MSNA is higher in endurance trained compared with sedentary men with similar levels of total body and abdominal adiposity. In addition, sympathetic baroreflex gain is lower in ET compared with SED men. That sympathetic baroreflex gain was lower in endurance trained compared with sedentary men regardless of the level of adiposity suggests an influence of the endurance trained state per se.
