Effect of training methods and body mass index on ankle injury in futsal players

Rationale and purpose This study aims to determine the effect of training methods (elastic resistance bands and wobble boards) and body mass index on ankle injuries in futsal players. Material and Methods This research refers to a quantitative approach. The research used in this study is quasi-experimental design research. The normality test uses the Shapiro Wilk test, with the rule that if the value (p) > 0.05 then it is normally distributed. The homogeneity test uses the Levene’s Test. Test the hypothesis to determine the difference in influence between 2 variables will use the two-way ANAVA test. Results The use of a wobble board produces a better improvement effect especially on balance and coordination. This happens because the movement when doing the wobble board requires good balance and coordination, almost all the muscles of the body will work together to adapt to this exercise. In elastic resistance band exercises it is done with isometric muscle contractions, because it will give a reaction but there is no change in muscle length, only the muscles increase. The effect of training using elastic resistance bands will increase blood circulation in joints and bone nutrition, improve the circulatory system with pull band movements. In relation to the search for both high body mass index and low body mass index, it was found that the use of the training method with a wobble board is better when compared to the training method with elastic resistance bands. So that there is no significant interaction between training methods and body mass index. Hypothesis Test I: to test the significance of two paired samples in the treatment group with normally distributed data, a parametric test was used, namely the paired sample t-test. Data on the results of hypothesis testing I from the analysis p = 0,009 it was found that there was an effect of giving Elastic resistance band and wobble board training methods to ankle injuries of futsal players. Hypothesis Test II: can be seen that the results of the paired sample t-test for SEBT from the data obtained p = 0,704 this means that Ha is rejected and Ho is accepted. So it can be concluded that body mass index has no effects on ankle injuries in futsal players. Hypothesis Test III: There is no interaction between training methods and body mass index on ankle injuries of futsal players. From the analysis of variance, the p-value = 0,477 is less than 0,05. Conclusions Based on the research, it can be interpreted that there are differences in the effect of the training methods given to futsal players’ ankle injuries. This is evidenced by the significance value of p = 0,003 α (0,05). There is no interaction between training methods and body mass index on ankle injuries of futsal players with a significance of 0,813.
