This study investigated the EMG muscle activation patterns of forward ice hockey skating at three velocities. Seven varsity hockey players from McGill University (age = 22.1 +/- 1.2 years, height = 1.8 +/- 0.1m, weight = 82.1 +/- 8.5 kg) participated. Testing was done using a skating treadmill. Skin was shaved, abraded and cleansed in the area of the electrode placement over the vastus medialis (VM), adductor magnus (AM), biceps femoris (BF), gluteus maximus, tibialis anterior (TA), peroneus longus (PL), and lateral gastrocnemius (GL) of the right lower limb. Subjects skated at 12 km/hr, 18 km/hr, and 24 km/hr. Repeated measures ANOVAs were performed, followed by Tukey post hoc tests. In general, the amplitude at speed 24km/hr was significantly higher than the speed of 12km/hr. There were few significant differences in temporal values. In conclusion, this study has shown that an increase in velocity results in an increase in the amount of muscle activation, but the muscle coordination patterns remain the same.
