Abstract
- Abstract: PURPOSE: To examine the effectiveness of TENS use on quadriceps muscular endurance during weight bearing exercise for apparently-healthy populations. METHODS: Fifteen male and fifteen female volunteers provided informed consent prior to participation. In Session 1, participants height, body mass, and one repetition maximum (1-RM) for non-dominant quadriceps was assessed using a knee extension machine. In Session 2, participant’s baseline maximum repetitions of non-dominant knee extensions at 40% of 1-RM was obtained. Participants were randomly selected into three groups: EXP: TENS unit with TENS activation; CON: no TENS unit with no TENS activation; PLA: TENS unit with no TENS activation. In Session 3, EXP, CON, and PLA participants performed maximum repetitions of non-dominant leg at 40% of 1-RM on the knee extension machine. Analysis of covariance (ANCOVA) was used to compare the change in repetitions from Session 2 and Session 3 between each treatment group, while controlling for baseline repetitions. RESULTS: No significant differences were found between groups in number of repetitions achieved at baseline (p = 0.703). The EXP group performed significantly more repetitions compared to the CON group (p=0.001) and PLA group (p=0.011) when controlling for baseline repetitions. CONCLUSION: Use of TENS during weight-bearing quadriceps muscular endurance activity significantly improves the number of repetitions performed by apparently-healthy populations.
