Abstract

There is a paucity of controlled studies concerning the off-season dryland training of hockey players. PURPOSE: To evaluate muscle activity and joint motion of the trunk and hip of hockey players skating on a hockey treadmill. METHODS: Seven male subjects, ages 18 to 21 years, were tested skating at 8 Mph on 0 percent and 30 percent grades on the treadmill. Electromyographical (EMG) data was collected from the following muscles: Rectus femoris, biceps femoris, adductor longus, gluteus maximus, rectus abdominus, and erector spinae. Motion analysis equipment was used to simultaneously collect kinematic data. RESULTS: There was an overall increase in the activity of all the muscles and a greater range of motion in the trunk and knee joints while skating on an incline as compared to level skating. Similar activation patterns were demonstrated in the rectus femoris, biceps femoris, gluteus maximus, adductor longus, and erector spinae muscles during level and inclined skating. CONCLUSION: The hockey treadmill may be beneficial in the training, rehabilitation and prevention of injuries in hockey players.
