Abstract
The objective of this study was to verify the effect of kinesio-taping (KT) application of the origin for muscle insertion (O>I) and insertion for muscle origin (I>O) in healthy participants, through surface electromyography and peak torque of gastrocnemius muscles. A total of 69 participants with an average age of 22.9±5.2 years were evaluated, 41 women with an average age of 22.0±5.1 years, BMI 25.1±4.6 kg/m2, and 28 men with an average age of 22.0±5.1 years, BMI 23.1±3.3 kg/m2, randomized under three conditions: O>I, I>O and no KT (control), repeated three times with five-minute rest between sessions. The peak torque of the gastrocnemius lateral (GML) and medial (GMM) muscles was evaluated at speeds 30º/s 60º/s 120º/s and muscle activity through surface electromyography. Repeated-measurement ANOVA showed effect only on the variable speed (F=767,1; p<0.001) and the variables condition (F=0.010; p=0.990) and interaction (F=0.199; p=0.892) were not significant. In electromyography, Root mean Square (RMS) did not differ in the conditions evaluated, presenting standard behavior without significant differences. The KT application regardless of being O>I or I>O muscular, did not alter the muscle recruitment or contribute to the increase in peak torque performance during the three speeds.
Highlights
The therapeutic elastic bandage technique (BET) consists of an intervention where, a type of elastic and adhesive tape known as Kinesio Taping® (KT) is applied to the skin providing a tension force that is produced by its stretch (Choi & Lee, 2018).With the KT application some results such as: 1- Neuromuscular optimization and coordination, 2- Alignment and reduction of joint instability, 3- Increase of muscle activation and strength, 4- Favor of static and dynamic functionality, are expected (Chang, et al, 2010; Fratocchi, et al, 2013; Simon, et al, 2014; Wong, et al, 2012)
The KT technique efficiency on muscle strength development and activation should be determined by tests that are capable of providing objective measures that are reliable and reproducible
The objective of this study was to verify the effect of two forms of kinesio-taping application in healthy participants, on muscle activation, and peak torque of gastrocnemius muscles
Summary
The therapeutic elastic bandage technique (BET) consists of an intervention where, a type of elastic and adhesive tape known as Kinesio Taping® (KT) is applied to the skin providing a tension force that is produced by its stretch (Choi & Lee, 2018).With the KT application some results such as: 1- Neuromuscular optimization and coordination, 2- Alignment and reduction of joint instability, 3- Increase of muscle activation and strength, 4- Favor of static and dynamic functionality, are expected (Chang, et al, 2010; Fratocchi, et al, 2013; Simon, et al, 2014; Wong, et al, 2012). The directions that KT can be applied (origin-insertion or insertion-origin) generate controversy in the literature, some authors report an increase in strength, torque and muscle activation regardless of the direction that KT was applied (Choi & Lee, 2018; Serrão, et al, 2016; Vercelli, et al, 2012). The KT technique efficiency on muscle strength development and activation should be determined by tests that are capable of providing objective measures that are reliable and reproducible. In this case, isokinetic dynamometer and electromyography are effective tests that can evaluate muscle torque and activation respectively
