Zusammenfassung
Hamstring strain injuries remain among the most problematic and most frequent sport injuries. Two of the most effective methods for prevention and rehabilitation of the hamstring strain injuries are: classic eccentric training using the Nordic hamstring exercise (NHE) and eccentric training in a lengthened position using the glider exercise. Both exercises have disadvantages that could be fixed by adding hip flexion during the NHE. Thus, the purpose of the study was to compare peak hamstring activity (measured by electromyography) between three eccentric exercises: the standard NHE, the modified NHE and the glider. Differences were statistically tested with the analysis of the variance for repeated measurements and the paired 2-tailed post-hoc t-test. Hamstring activity during the modified NHE was significantly lower compared to the NHE and significantly higher compared to the glider. The results indicate that implementing the modified NHE could increase the effectiveness of already established rehabilitation protocols and help reduce the risk of hamstring (re-)injury.
