Key result
Incremental leg cycling from very mild (10 W) to exhausting (190 W) demonstrated non-uniform arterial baroreflex control over muscle sympathetic nerve activity compared to rest.

Non-uniform baroreflex control may shape intensity-dependent sympathetic responses during exercise; leaves open translation to patients with cardiovascular disease.

Does incremental leg cycling alter arterial baroreflex control over muscle sympathetic nerve activity in healthy subjects?
Arterial baroreflex control over muscle sympathetic nerve activity is not uniform during incremental exercise, suggesting a mechanism for matching sympathetic and cardiovascular responses to exercise intensity.
Ichinose et al. (2008) conducted an observational in healthy subjects (n=15). incremental leg cycling vs. rest was evaluated on arterial baroreflex (ABR) control over muscle sympathetic nerve activity (MSNA). Incremental leg cycling from very mild (10 W) to exhausting (190 W) demonstrated non-uniform arterial baroreflex control over muscle sympathetic nerve activity compared to rest.
