Double product response and diastolic blood pressure in treadmill, stationary bicycle and muscular circuit exercise

Resumen

Among the various causes for cardiovascular problems affecting the world population nowadays, the most relevant risk factors is sedentary lifestyle. Many studies have been carried out to analyse and elucidate main adaptations on the cardiovascular system stimulated by different sorts of exercises.In this way, this study had aimed at comparing the acute response of double product (DP) and diastolic blood pressure (DBP) after treadmill (TRM), stationary bicycle (BIC) or muscle circuit training (MCT) exercises. Nine individuals (6 women and 3 men) exercised at 60% of heart rate reserve (HRR) on the TRM and BIC and at 60% of one repetition maximum (1RM) in MCT. The results showed that pre- and post-effort DP were significantly difference in all three exercises. However, DP did not differ among exercise types. The hypotensive DBP pos-effort response was greater in MCT. According to the results, it was concluded that there is no difference on the heart work demand rate estimated by DP among the three exercises and MCT at 60% 1RM provokes a greater hypotensive DBP post-effort response.
