The purpose of this study was to determine if there was any significant difference in overall leg strength gains in individuals with sickle-cell-trait as compared to non-sickle-cell-trait individuals, as measured by the leg dynamometer. Twenty black male first-year college students were used in this study. The subjects were divided into a control group which was randomly assigned and an experiemental group assigned on the basis of sickle-cell test results. The subjects were pretested for overall leg strength. Both groups then followed the same exercise program three days a week for an eight-week period. All exercise periods consisted of five minutes. On completion of the exercise program, a posttest was administered to both groups. Both a t-test and a Mann-Whitney U-test were used to test the hypothesis. Results indicated that high intensity exercise had no more effect on overall strength gained in the legs of non-sickle-cell-trait than on sickle-cell-trait individuals. (Author/PB)
