title: [Effect of strength-building training on manifestation of pressor reflex from working muscles receptors].
abstract: Ten young normal volunteers and 8 armrestlers worked with forearm muscles till refusal at 30% of maximal arbitrary force. Work was either static or rhythmic with alternation of 20-s period of contraction and relaxation and followed by post-work arterial occlusion of the forearm muscles (PWAO). Heart rate (HR), blood pressure (BP) and muscular vessels-related sympathetic activity (MRSA) were measured continuously. MRSA was registered in n. peroneus using the microneurographic technique. Static work and subsequent PWAO produced different BP and MRSA neither in sportsmen nor amateurs. On the contrary, rhythmic work followed by PWAO suppressed the muscle pressor reflex in sportsmen significantly. The authors consider possible origination of the effect by change in energy supply to working muscles, enhanced extraction of metabolites, and sensory decrement of sportsmen's muscular receptors.
