The Influence of Acute Exercise on Torque Decline Between Positions in Collegiate Female Soccer Players

To examine the effects of a fatigue inducing bout of isokinetic exercise on peak torque decline for the leg flexor and leg extensor muscle groups between playing positions in Division I collegiate female soccer players. Eighteen healthy female individuals (seven defenders: mean + or - age= 19.86 + or - 0.83; seven midfielders: mean + or - age= 20.57 + or - 1.59; four forwards: mean + or - age= 20 + or - 0) volunteered to participate in the study. Peak torque of the right leg extensors and flexors was assessed on a Biodex System 3 dynamometer (Biodex Medical Systems, Inc., Shirley, NY USA) at 180[degrees] s-1. Following a general warm-up, participants performed 50 consecutive maximal leg extensions and leg flexions in tandem. Peak torque and least torque values across the 50 repetitions for both leg flexors and leg extensors were used to calculate the percent of torque decline. There was no significant difference (p = 0.78) for peak torque percent decline for any of the player position groups.
