Abstract

This study was aimed to investigate the acute effect of shoulder resistive exercise on cardiovascular responses in normal healthy subjects. We recruited twenty normal male subjects without musculoskeletal diseases were participated in. Exercise program consisted of abduction, internal rotation, extension, flexion, and military press by using elastic tubing. This program were performed by repeating above five exercises 30 times each with 60%RM intensity. Before and after exercise program, mean arterial blood pressure, heart rate, and plasma concentrations of norepinephrine, epinephrine, renin activity, vasopressin, and aldosterone were measured. Resistive exercise of shoulder resulted in a significant increase in mean blood pressure, heart rate, plasma norepinephrine & epinephrine levels in post-exercise (p<0.001). But there were no significant changes in the hormone levels, such as renin activity, vasopressin and aldosterone. These results indicate that peripheral sympathetic nervous system plays a more important role in acute cardiovascular response to resistive exercise of shoulder.
