Influence of elastic taping on knee extensor torque in healthy women

Abstract

Introduction: The function of the quadriceps femoris muscle is widely studied in the literature, for maintaining your strength levels gives better stability and less risk of injury to the knee joint complex. A strategy used in improving the performance and injury prevention is the application of muscle activation technique with the elastic bandage, widespread on the market as kinesio taping. Objective: Thus the aim of this study was to investigate the influence of taping kinesio knee extensor torque in women without complaints of pain in the knee. Methods: A randomized, double-blind crossover was performed in 16 women with no previous history of injuries or complaints of pain in the knee. The protocol established ver isokinetic dynamometer for knee torque assessment was concentric-concentric, angular speed set at 60º / s. They were held a series of three repetitions for familiarization and three sets of five reps for assessing outcomes, with 120 seconds of rest between reps. Knee extensor torque measurements were performed after 24 hours of application of taping kinesio the oblique vastus muscles, long lateral vast, oblique vastus lateralis with muscle activation technique, or placebo, according to randomization. The data analyzed were: peak torque, maximum repetition of the work, fatigue of the work performed, agonist and antagonist ratio, deceleration time and the time to reach peak torque. Results: For the test-retest reliability (agreement) analysis in the familiarization sessions, the two-way random-effects intraclass correlation coefficient was calculated using an absolute agreement definition and 95% confidence interval (95%CI = estimate = ± 1.96SE). Torque data were compared between groups using the Paired Student's T-test, with a significance level of 5% (p-value: MaxRT = 0.906; PT = 0.437; FT = 0.837; Rel Ag./Antag. = 0.720; TDesacel. = 0.362; TPT = 0.789). No statistically significant or clinically relevant differences were observed between the use of placebo and kinesio taping in any outcome variables considered in the study. Conclusion: Thus, it can be concluded that there was no improvement in the performance of the quadriceps femoris with the use of kinesio taping.
