- Abstract
Objective: The purpose of this study was to investigate the effect of Nordic hamstring exercise group with Nordic hamstring exercise group that was doing resistance movements together on the hamstring muscle by comparing the measurement of fascicle length(FL), muscle thickness(MT), of hamstring muscle and the size of the pennation angle(PA) after a certain period of intervention. Method: This study was conducted by recruiting 20 physically healthy adult males and 21 females who agreed to participate in this study after the preliminary study. The training group(TG) that did the Nordic hamstring exercise and resistance movement together(RNHE) and the controlled group(CG) that did Nordic hamstring exercise(NHE) were measured for hamstring muscle 6 weeks after exercise intervention according to the predetermined protocol for 5 weeks and after 3 weeks of tracing observation, they were measured to compare the prognosis after 9 weeks. All measurements in the experiment were conducted in repeated measured ANOVA, and t-test was used to compare the two groups. Findings: The result of the experiment showed statistically significant differences in the FL, MT, of hamstring muscle and the size of the PA in both groups. In addition, the FL of hamstring muscle and the size of the PA showed significant differences in 6 weeks and 9 weeks. Improvements: In conclusion, it was confirmed that applying RNHE has effect in the MT and FL of hamstring muscle and the size of the PA, and this can be an even more effective exercise intervention that can lower the risk of hamstring injury when applied to athletes.
