Reliability of selected physical performance tests in young adult women.

The purposes of this investigation were to establish the reliability of selected physical performance tests in women athletes and nonathletes and to determine performance differences between groups. Fifty women (25 athletes, 25 nonathletes) performed 5 tests in 2 sessions. The performance tests included the figure-eight hop test, up-and-down hop test, side-to-side hop test, hexagon hop test, and zigzag run test. Intraclass correlation coefficients (ICC [2, 1]) were calculated for trial-to-trial, intertester, and day-to-day reliability. Independent t-tests with Bonferroni adjustment (alpha = 0.01) were used for each individual test to compare differences between groups. All tests showed good reliability values (ICC > or = 0.76) in the nonathlete group for all conditions and varied reliability values (0.48-0.99) among conditions in the athlete group. The independent t-tests showed a statistically significant group effect (t > or = 3.041; p < or = 0.004) for all tests. The results showed that these physical performance tests are reliable measurement tools in the female population.
