| dc.description.abstract | English: Introduction: The effects of Kinesiology Tape on the neuromuscular system have been discussed in recent literature. The effects on power, range of motion, proprioception, and muscle strength can be vital to reach optimal functional performance. There is no research available that studies the effect of Kinesiology Tape on the scapular stabilisers in tennis players. Aim: The aim of the study was to determine if Kinesiology Tape can have i) an effect on the muscle activation of serratus anterior and lower trapezius muscles and ii) the ball speed of the tennis serve. Method: The study was a quantitive analitical case study on 19 male and 11 female (n = 30) tennis players (mean age = 19.83 years). The muscle activation of the serratus anterior and lower trapezius muscles were measured by means of EMG. Ball speed were measured with a Radar Speedgun. The intervention was the application of Kinesiology Tape on the scapular stabilisers. Results: The lower trapezius muscle`s mean highest measurement (p = 0.7143; t = 0.37; df = 29) and maximum measurements (p-value = 0.5376; t-value = -0.62; df = 29) improved, but were not statistical significant. The p-values for the serratus anterior muscles were 0.2181 (highest measurement) (t-values = 1.26; df = 29) and 0.0045 (mean measurement) (t-value = 3.08; df = 29) which are statistical significant. The mean minimum service speed improved after the application of Kinesiology Tape with 3.1 km/h, the mean maximum speed with 1.666 km/h and the mean mean speed with 1.9233 km/h. There was a statistical significant improvement of 1.9233 km/h in the mean serve speed (p = 0.218; t-value = 1.26; df = 29). Discussion and conclusion: It appears that there can be a statistical significant improvement in the mean EMG activity of the serratus anterior muscle after the application of Kinesiology Tape on the scapular stabilisers. No conclusion can be made on the effect the taping has neither on the ball speed of the serve nor on the activation of the lower trapezius muscle. The results are difficult to interpret because of the complex biomechanical interaction of the kinetic chain. | en_ZA |
| dc.description.abstract | Afrikaans: Inleiding: Die effekte van Kinesiologie Pleister op die neuromuskulêre stelsel word deur literatuur beskryf. Die moontlike effekte op krag, omvang van beweging, propriosepsie, spiersterkte en sportprestasie kan van kardinale belang wees om optimale funksionele prestasie te verseker. Daar is egter nog geen studies beskikbaar wat die effek op die skapulêre stabiliseerders in tennisspelers ondersoek het nie. Doelwit: Die doel van die studie was om te bepaal of Kinesiologie Pleister i) `n invloed kan hê op die aktivering van die serratus anterior en laer trapezius spiere en ii) die balspoed tydens die tennisafslaan. Metode: `n Kwantitatiewe analitiese gevalskontrole studie is uitgevoer (n = 30), op 19 manlike en 11 vroulike tennisspelers (gemiddelde ouderdom = 19.93 jaar). Spieraktivering is deur `n EMG-masjien geneem van die serratus anterior en laer trapezius. `n Radar Spoedgeweer het die afslaanspoed geneem. Die intervensie was die aanwending van Kinesiologie Pleister op die skapulêre stabiliseerders. Resultate: Die laer trapezius spier se gemiddelde hoogste lesing (p = 0.7143; twaarde = 0.37; df = 29) en maksimum lesings (p = 0.5376; t = -0.62; df = 29) het verbeter na die aanwending van Kinesiologie Pleister, maar was nie statisties betekenisvol nie. Die p-waardes vir die serratus anterior spier se hoogste en gemiddelde lesings na die aanwending van Kinesiologie Pleister was onderskeidelik 0.2181 (t-waarde = 1.26; df = 29) en 0.0045 (t-waarde = 3.08; df = 29) met laasgenoemde statisties beduidend. Die gemiddelde minimum afslaanspoed het verbeter na die aanwending van Kinesiologie Pleister met 3.1 km/h, gemiddelde maksimum spoed met 1.666 km/h en die gemiddelde gemiddeld met 1.9233 km/h. Daar was 1.9233 km/h verbetering in die gemiddelde afslaanspoed (p = 0.218; t-waarde = 1.26; df = 29), maar nie statisties betekenisvol nie. Bespreking en gevolgtrekking: Dit blyk of die aanwending van Kinesiologie Pleister op die skapulêre stabiliseerders die serratus anterior spier se gemiddelde EMG-lesing statisties beduidend kan verbeter. Geen gevolgtrekkings kan egter gemaak word oor die invloed wat dit het op die balspoed van die tennisafslaan of op die aktivering van die laer trapezius spier nie. Die bevindinge is moeilik om te interpreteer weens die komplekse biomeganiese interaksie van die hele kinetiese ketting. | |
