摘要:	Purpose: The main purpose of this research study was designed to test and examine results of the hamstring/ quadriceps strength and power ratio in male track & field and swimming athletes. Method: The study selected twenty-four (24) male subjects, twelve (12) members each from two collegiate athletes sports teams, the track & field team and swimming team. They were tested for strength and power ratio between their hamstring and quadriceps, only on preferred legs. The SPSS t-test ANOVA compares the mean differences between groups that have been split on two independent variables. A different analyzing process was used with each of my Hypotheses, there were two different analyzing factors used. The Independent t-test for Group Statistics and Levene’s Test for Equality of Variances were utilized to answer the first hypothesis. Results: There was no significant different found between H/Q Strength and Power Ratios in male track and swim teams, as shown the Independent t-test. A significant difference between track and swimming athletes was found at the 60° angle, but for the left leg strength and power ratio at for the left leg, (t = -2.923, p > .05). There was a significant difference between track and swimming team in strength and power ratio at 180° on the right leg, (t = -2.103, p < .05). There was no significant difference in the rest of variables. The strength and power ratios between legs, was a significant difference (p < .05) shown in the Paired Sample Correlations, with P legs at all degrees, 60°, 180° and 240°. A significant difference in leg strength and power ratios was found at difference degrees (p < .05). When the differences were compared the preferred legs were found to be greater for the Means and Standard Deviation within all degrees tested. Conclusion: The athletes could be at risk for muscle damage, during leg speed changes, due to the imbalance in leg strength and power ratios between legs and more importance should be placed on making sure that both legs are balance in strength and power.
