To analyze the effect of warming up exercise methods by analyzing the impact of stretching exercises and treadmill walking on lower extremity muscle activity.
The subjects were twelve young healthy adults. They performed four methods of warm-up exercises for ten minutes each week, once a week for four weeks: non-exercises, treadmill walking, stretching exercises, and both treadmill walking and stretching exercises. An EMG measured the muscle activity of the rectus femoris and medial gastrocnemius. The one-way ANOVA was used to compare the difference in muscle activity between the four warm-up exercise methods.
No interaction effect was shown regarding muscle activities. There was no notable change in activity within the muscle based on the different warm-up methods. Muscle activity between the pre-and post-test also failed to display a difference worthy of note.
The short period of time allocated for warm-up exercises may not have been adequate to affect the muscle activities of the lower extremities. A longer program may be needed to study changes in muscle activity within the clinical area.
