Twelve female collegiate students (age 19.8 yrs ±1.3; ht  64 in ± .9; wt 140 lb ± 11.3) performed three core balancing tasks on the Lafayette Instrument Company Stability Platform (Model 16030). Subjects performed a quadrupled arm raise with the body parallel to the tilt axis and alternated raising their left and right arms according to a metronome set at 40 beats per min for 30 seconds. Subjects then performed a quadrupled arm raise with the body perpendicular to the tilt axis and alternated raising their left and right arms according to a metronome set at 40 beats per min for 30 seconds. The final core task was a kneeling test; subjects alternated their arms at 60 beats per min. Hip extensor and abductor strengths were measured using the Lafayette Manual Muscle Tester (Model 01163). Hip extensor strength was measured 1-1.5 inches above the middle of the thigh while the knee was flexed. The hip abductor was measured on the lateral thigh, 4 inches above the distal end of the thigh. Fifteen seconds of rest was provided between each trial. This measurement had three trials, maximum and the average measurements were used.

Extremely poor correlations (0.066, 0.022, 0.030) were found between changes in hip extensor and hip abductor strengths compared to the three core balancing tasks. Subjects that demonstrated a small change in hip extensor and abductor strengths scores were more likely to score poorly on the three core strength and stability balancing tasks. Subjects that demonstrated a large change in hip extensor and abductor strength were more likely to have consistent scores in core strength and stability balancing tasks.
