Weight-training-induced attenuation of the circulatory response of older males to weight lifting

We examined the effects of 12 wk of dynamic strength training on the heart rate (HR) and blood pressure of older male subjects during 10 repetitions of single-arm curl and single- and double-leg press at 60 and 80% of both the pre- and posttraining maximum capacities and during single maximum lifts (1 RM). The circulatory responses were greater at 80% of 1 RM than at 60% and increased with active muscle mass. After training, the 1 RMs increased …
