An Investigation About the Effective Exercise Methods for Health Promotion Through the Measurement of Lower Limb Muscle Activities with EMG（Electromyography）
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.38 Vol.38】
ABSTRACT
Walking is widely conducted among people as an exercise for health promotion. In this study, in order to investigate more effective way of exercise compared to normal walking, muscle activities of the lower limb were measured utilizing electromyography so as to study the quantitative and qualitative analyses about muscle activities during exercises. Measurements of muscle activities during SLR exercise and during the examinations of the knee extension and flexion maximum strength in sitting position by electromyography showed that quantitative and qualitative evaluation of the muscle activities were possible. It also revealed that the amount or quality of muscle activities varies depending on the muscle difference. In particular, quality of muscle activities change by aging or it alters (frequencies decline) during continuous muscle contraction. In addition, we indicated the difference of the way or amount of muscle activities about several muscles in the lower extremities, depending on the normal walking, fast walking with wider stride or fast walking with increased pitch. And the amount of muscle activities was found to be increased during fast walking, both ways, and slow jogging compared to those during normal walking, and the muscles on which statistically significant increases were observed to be different depending on the way of fast walking or slow jogging. From these not merely conducting normal walking, but adopting different way of fast walking or slow jogging will lead to the training of various type of muscles and attain more effective exercise.
