A Kinesiological and Electromyographic Study of Exercise Walking
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.12 Vol.12】
Recently Exercise Walking has been increasingly popular in our country as well as in the United States. And it is very likely to surpass jogging in popularity before long. We examined Exercise Walking electromyographically. Also we made an electromyographic attempt to* find whether or not Exercise Walking can be substituted for jogging in terms of the moving patterns and the functional mechanism of the muscles :
1. In Exercise Walking, more load was exerted than in everyday walking, and similar levels of muscle activities were observed as in longer-stride fast walking, stair climbing, and jogging. During the push-off period of Exercise Walking, the Rectus femoris, knee joint extensor, acted strongly. The electromyographic (EMG) patterns were found similar to those of longer-stride fast walking and stair climbing. In Exercise Walking, however, the hamstrings did not act unlike in jogging.
2. We attempted to find a movement which shows similar EMG patterns to those of jogging, and we found the walking in ballet was the case. We applied some characteristics of ballet walking to everyday walking walking with the backraised, with the feet landed on the imaginary center line and the toes pointed slightly to the outside, and with the feet kicked backward to shift the center of gravity forward quickly. As a result, during the push-off period, the hamstrings, hip joint extensor, acted and showed similar EMG pat-terns to those of jogging. During the stance phase, moreover, the Gluteus maximus acted for the stabilized pelvis and firmly tucked-in buttocks and contributed to a good posture. This new type of walking showed similar muscle activities to jogging and made a proper posture possible. We call this New Exercise Walking.
3. We believe that this New Exercise Walking is very useful for those who are fitness-conscious and also for those who are required aesthetic walking like professional fashion models.
4. We conclude that it is, more effective to combine Exercise Walking with New Exercise Walking according to the purpose and place.
