TI  - The influence of athletic status on maximal and rapid isometric torque 
      characteristics and postural balance performance in Division I female soccer 
      athletes and non-athlete controls.

AB  - The purpose of this study was to examine the effectiveness of maximal and rapid 
      isometric torque characteristics of the hip extensor muscles and postural balance 
      performance to discriminate between female collegiate soccer athletes and 
      non-athlete controls. Ten athletes (mean +/- SE: age = 19.20 +/- 0.36 year; mass = 
      62.23 +/- 3.12 kg; height = 162.43 +/- 1.70 cm) and 10 non-athletes (age = 20.30 
      +/- 0.40 year; mass = 69.64 +/- 3.20 kg; height = 163.22 +/- 2.10 cm) performed two 
      isometric maximal voluntary contractions (MVCs) of the hip extensor muscles. Peak 
      torque (PT) and absolute and relative rate of torque development (RTD) at early 
      (0-50 ms) and late (100-200 ms) phases of muscle contraction were examined during 
      each MVC. Postural balance was assessed using a commercially designed balance 
      testing device, which provides a measurement of static stability based on sway 
      index (SI). Results indicated that absolute and relative RTD at 0-50 ms (RTD50 
      and RTD50norm) were greater (P = 0.007 and 0.026), and postural SI was lower 
      (P = 0.022) in the athletes compared with the non-athletes. However, no 
      differences (P = 0.375-0.709) were observed for PT nor absolute and relative RTD 
      at 100-200 ms (RTD100-200 and RTD100-200norm). Significant relationships were 
      also observed between RTD50 and RTD50norm and SI (r = -0.559 and -0.521; 
      P = 0.010 and 0.019). These findings suggest that early rapid torque 
      characteristics of the hip extensor muscles and postural balance performance may 
      be sensitive and effective measures for discriminating between college-aged 
      athletes and non-athletes. Coaches and practitioners may use these findings as 
      performance evaluation tools to help in identifying athletes with both superior 
      early rapid torque and balance performance abilities, which may possibly be an 
      indicator of overall athletic potential.
