Determination of Optimal Muscular Power Development in Individuals over Age Fifty. (Exercise Physiology and Fitness)

Article excerpt

The preservation of muscular power in older adults greatly decreases the risk of disability and enhances functional independence. Few studies have examined the impact that different training protocols have on muscular power in individuals over the age of 50 years. Therefore, the purpose of the study was to examine whether muscular power can be improved to a greater extent by utilizing a power training exercise program (PTEP) as opposed to a conventional strength training exercise program (STEP). Thirteen active exercisers, over the age of 50 (M= 62.2 years, SD = 5.92), volunteered for study participation. The participants were randomly assigned into either the 8-week (PTEP) group (4 men and 3 women) or the (STEP) group (3 men and 3 women). Three participants did not satisfy study requirements and were eliminated from the study. The effectiveness of the muscular power training program was evaluated by a three-way analysis of variance (Gender x Group x Time design), with repeated measures on time was performed on the power and strength variables of chest press (GP), lat machine (LM), and leg press (EP); as well as on body weight (BW) and fat free mass (FFM). Gender specific and group-related differences in baseline BW, FEM, and power and strength variables were assessed using t tests. …
