| Summary: | The elderly are the fastest growing population today. Weight training may be beneficial in prolonging quality and independence of lifestyles for the elderly. The effect of strength and hypertrophy have been shown to directly counter the degenerative process associated with aging. Literary reviews of elderly weight training studies resound of contradictory results and have fueled the debates as to whether strength and hyper-trophy are effects of weight training in the elderly. The meta-analysis was chosen in order to quantify the results of elderly weight training studies, so to ascertain if the effects of studies may be attributed to training protocols or are a duct of methodology. A literature search was conducted on Medline, BIOSIS and Eric databases. The four criteria that studies had to meet in order to be included in the meta-analysis were: 1) used human subjects; 2) had a sample mean 60 years, or older; 3) addressed strength or hypertrophy; 4) contained sufficient data to calculate an effect size. Twenty-seven studies met all four criteria and were used in the meta-analysis. The studies were classified by independent variables for strength (intensity, sample composition and sample range) and hypertrophy (significance, assessment technique, sample composition and sample range). Effect size magnitude was categorized utilizing Cohen's categories of magnitude and ANOVAs were run for between groups and within group designs for all of the independent classifications for strength and hypertrophy. All statistical tests were conducted with an alpha level of .05. Within the limitations of this study and based on the results, the following conclusions were established: 1. Muscular strength is an effect of elderly weight training. 2. Hypertrophy is a physical adaptation for elderly weight training. 3. Intensities above or below 70% do not differentially influence results of the strength effect in elderly weight training. 4. Assessment techniques for hypertrophy do influence the results in elderly weight training. 5. The sample composition does influence the strength effect results in elderly weight training. 6. Sample range over ten years does influence the hypertrophy effect but not the strength effect in elderly weight training. |
