The purpose of this study was to establish baseline data on the physiological characteristics of adolescent club-level female soccer players and to make comparisons between the adolescent soccer players, normative data, athletes of other sports, and nonathletes. Measurements for fourteen female subjects (Age: 13.86 + 0.36 yrs; Ht: 163.25 + 6.66 cm; Wt: 55.57 + 10.47 kg) included the Illinois Agility Run (agility), PACER (VO[sub 2max]), Wingate test (anaerobic power), isokinetic torque (leg extension/flexion peak torque at 30 and 180 deg-s^-1), and skinfolds (percent body fat). All five tests were administered on two different days within 5-10 days of the other. Statistical analyses to determine stability reliability were completed for percent body fat, agility, anaerobic power and VO[sub 2max] by running a one-way repeated measures ANOVA. Internal consistency was computed using a one-way repeated measures ANOVA for measures of percent body fat, muscular peak torque between kicks (1-5) and between tests (extension 30 deg-s^-1 test 1 vs. extension 30 deg-s^-1 test 2). Coefficients of Variation were also determined for percent body fat and peak torque. The alpha level was set at .05. Results of the mean values for the tests were: agility: 17.15 + 1.01 s; VO[sub 2max]: 47.56 + 4.27 ml-kg^-1-min^-1; anaerobic power: 6.03 + 1.28 W-kg^-1 and 323.76 + 40.90 W; peak torque at extension 30 deg-s^-1: 140.19 + 23.80, flexion 30 deg-s^-1 64.07 + 14.31, extension 180 deg-s^-1: 89.94 ? 17.26, flexion 180 deg-s^-1: 46.56 ? 10.50; and % body fat: 18.89 + 6.18. Subjects were found to have similar mean performances to other athletes and slightly better values than non-athletes of similar age. However, hamstring strength was reported to be lower than exhibited by other athletes, and training to increase hamstring strength was recommended for the soccer athletes. Further research on the physiological characteristics of this age group is needed to increase the availability of normative data for comparison purposes and to help establish training guidelines.
