Differentiated ratings of perceived exertion during physical conditioning of older individuals using leg-weight loading.

摘要: Use of leg weights for physical conditioning was evaluated in 8 middle-aged male Ss; four Ss similar age served as a control group. Pre- and post-training evaluation consisted heart rate oxygen uptake responses to five submaximal work loads which involved either level walking or cycling. Differentiated ratings perceived exertion elicited each load were: local muscular rating; central cardio-pulmonary an over-all general rating. Submaximal decreased 6 9 beats/min. from pretraining values all after training. The differentiated training generally reflected reduced strain on the cardiovascular system also improved functioning working muscles with However, when one set sensations dominated exertional perception others appear have been perceptually de-emphasized. Local factors seemed dominate cycling, but appeared play more important role treadmill walking, at least within range velocities investigated.
