The effect of hand-held weights on the physiological responses to walking exercise

Abstract

Ting of perceived exertion were significantly greater (P< 0.01) when HWs were added to walking exercise performed at constant treadmill speed and grade. To evaluate whether the evaluated BP response was caused by HWs independent of exercise load, heart rate was held constant at 75% maximum heart rate reserve during the third submaximal test. Systolic BP (151.1 ± 15.3 mm Hg vs 160.1 ± 16.9 mm Hg) and rate pressure product (252.1 ± 27.0 vs 237.3 ± 25.1) were significantly greater (P < 0.05) during exercise with HWs. Physiological responses to maximal exercise with and without 3 lb HWs were similar. The time to exhaustion, however, was reduced (P < 0.01) with HWs. (719.3 ± 98.1 s with HWs vs 784.4 ± 118.9 s without HWs). These data indicate that 3-lb HWs can increase the metabolic cost of training (1 MET, 7 to 13 b · min−1) and may be useful in exercise prescription for individuals who do not want to run or are limited in the speed at which they can walk. Due to the exaggerated BP response, caution should be used when prescribing HW exercise for patients where increasing afterload may be a problem. ©1987The American College of Sports Medicine...
