Abstract

Eleven male and nine female subjects aged 18-26 years were assigned at random to one of two treatment groups: biofeedback and control. Muscle soreness was produced in all subjects by a 60 maximal eccentric contraction of the quadriceps group. The subjects in the biofeedback group applied auditory electromyographic (EMG) feedback at 6, 25, 30, 49 and 54 hours after the exercise while the control group applied no treatment to the exercised leg. Recordings of EMG activity were made immediately before and after exercise andat 24, 48, and 72 hours following exercise. Recordings of perceived pain were made immediately after exercise and at 24, 48, and 72 hours following exercise. NO comparsions involving EMG activity significantly differed. However, the biofeedback group had significantly lower pain than the control group across all recordings and at 48 hours following exercise. Moreover, the pain of thesubjects in both the biofeedback and control group significantly differed across recordings. Verf.-Referat
