AB  - The purpose of this study was to determine if maximal and rapid isometric torque 
      characteristics could discriminate starters from nonstarters in elite Division I 
      American collegiate football players. Sixteen starters (mean +/- SD: age = 20.81 +/- 
      1.28 years; height = 184.53 +/- 6.58 cm; and mass = 108.69 +/- 22.16 kg) and 15 
      nonstarters (20.40 +/- 1.68 years; 182.27 +/- 10.52 cm; and 104.60 +/- 22.44 kg) 
      performed isometric maximal voluntary contractions (MVCs) of the leg flexor and 
      extensor muscle groups. Peak torque (PT), rate of torque development (RTD), the 
      time to peak RTD (TTRTDpeak), contractile impulse (IMPULSE), and absolute torque 
      values (TORQUE) at specific time intervals were calculated from a torque-time 
      curve. The results indicated significant and nonsignificant differences between 
      starters and nonstarters for the early rapid leg flexion torque characteristics 
      that included RTD, IMPULSE, and TORQUE at 30 and 50 milliseconds, and TTRTDpeak. 
      These variables also demonstrated the largest effect sizes of all the variables 
      examined (0.71-0.82). None of the leg extensor variables, leg flexion PT, or 
      later leg flexion rapid torque variables (>/= 100 milliseconds) were significant 
      discriminators of playing level. These findings suggest that the early rapid leg 
      flexion torque variables may provide an effective and sensitive muscle 
      performance measurement in the identification of collegiate football talent. 
      Further, coaches and practitioners may use these findings when designing training 
      programs for collegiate football players with the intent to maximize rapid leg 
      flexion characteristics.
