Abstract
Eccentric activity is a type of activity facilitated by the addition of one or several muscles and often leaves the effects of pain even damage to muscle cells. The study aimed to determine the effect of the application of neuromuscular taping decompression techniques to muscle damage after eccentric movement activity. The type of research conducted is experimental research with post test only with control group design. Fourteen samples were selected from non-athlete populations at SMAN 1 Driyorejo based on consecutive sampling techniques and then divided into two groups randomly. Intervention of neuromuscular taping decompression techniques was given to the treatment group before performing eccentric movement activities. The elbow shoulder-extension flexion movement by holding 9% weight in 20 seconds was chosen as the protocol of eccentric movement activity. Measuring indicators of muscle damage using a serum Ck muscle examination 6 hours after rest. The results of the independent t-test showed no significant difference in the variable of muscle damage (p> 0.05). It was concluded from this study that the neuromuscular taping decompression technique failed to prevent muscle damage after eccentric movement activity.
Highlights
Eccentric muscle activity is often found in resistance training or in other sports activities
Indicators of muscle damage can be seen through serum levels of creatine kinase, Baird, et al (2012)
Samples were obtained based on inclusion criteria, namely male sex, age 15-16 years, not doing eccentric activity 3 days before the study, weighing 50-65 kg, height 160-175 cm, arm length 54-58 cm, and has a load holding time of 20-24 seconds
Summary
Eccentric muscle activity is often found in resistance training or in other sports activities. Eccentric activity is physical activity that involves contraction of one or several muscles that have been elongated and accompanied by an increase in muscle strength, Chen (2017): Purwanto (2014), so eccentric contractions produce greater muscle damage than concentric contractions, Suryadi (2014). Cases of acute muscle damage reach 10-55% in overall sports injuries due to eccentric muscle contractions, Maffulli (2015). Indicators of muscle damage can be seen through serum levels of creatine kinase, Baird, et al (2012). Serum creatine kinase in athletes decreases 1 day after eccentric activity and increases up to 6 days in non-athletes, Lieber (2018). Acute muscle damage accounts for 10-55% of all sports injuries due to eccentric muscle contractions, Maffulli, et al (2015).
