The Effect of Two Training Models of TRX on Anaerobic Power and Body Composition of Young and Teenager Taekwondo Athletes

TRX training are one of the new resistance training that play a role in increasing strength, power, balance and stabilizing the body structure and increase neuromuscular coordination. The aim of this study was to determine the effect of two training models of TRX on anaerobic power and body composition of young and teenager taekwondo athletes. Thirty-six young and teenager taekwondo boys with a mean age of 17.14±6.040 years participated in the study and randomly were divided to three training groups of 12 people including: TRX training in the form of intense interval training TRX-HIIT (TH), TRX training alone TRX (T) and the control group. After examining the normality of data distribution using Kolmogorov-Smirnov test, in order to determine the differences intragroup, the dependent T test was used and to determine the differences between the groups, the statistical method on way-ANOVA was used (P≤0.05). In both training groups, a significant increase in participants' anaerobic power was observed, which anaerobic power was significantly higher in training group TH (P= 0.001). Also, in both training groups, after 5 weeks of training, a significant decrease in body fat percentage (body composition) was observed (P= 0.001). The results of this study showed that taekwondo athletes and trainers can use both training models to increase anaerobic power and reduce body fat percentage and it is suggested to use TRX training in the form of intense interval to get better results in equal time.
