The purpose of this study was to investigate the effects of shoe weight on cardiorespiratory response and energy economy to walking exercise with added shoe weight, and to verify the shoe weight and walking economy. Subjects were composed of eight middle-aged women and performed 3 day a week, during 8weeks, and on an average 30 minute a day. The findings of this study were as follows. 1. V˙O₂ and V˙O₂/kg were significantly increased 300㎖/min(η²=27.9. p<.05) and /kg/min(η² =40.7%, p<.01) respectively. HR was significantly increased 14beats(η²=14.9%, p<.01) and energy expenditure were significantly increased 2Cal/min(η²=51.9%, p<.0l) and 130Cal/h(η²= 53.3%, p<.001) respectively. This results suggest that there are influenced by diet shoe(1200g) than common shoe(400g) in the increase of energy expenditure as well as the increase of cardiorespiratory function and confirmed the previous studies that additional body weight affects cardiorespiratory function and energy expenditure. Especially, shoe weight as additional weight method is easy to use and is things necessary for daily life. Therefore it may be useful for the people who can't take exercise because of lack of exercise time and place.

The Purpose of this study investigate the effects of sports massage after Taekwondo Training. Twenty male subjects participated in this study. divided four group : control(n=5), stroking(effleurage,n=5). kneading(petrissage, n=5).vibration and shaking(n=5). In frist experiment session, Taekwondo Training performed using Bruce Protocol, then second experimental started at 90% VO₂Max during forty minute. Blood cell count and immune function measured pre-, immediately-, and post exercise. After Taekwondo Training, the concentration of red blood cell, hemoglobin. hematocrit, platelet, total white bolld cell, basophil, momocyte, lymphocyte were more higher in Control and effleurage than that of other groups, but the concentration of neutrophil and eosinophil did show higher values in petrissage and vibration than that of control and effleurage. In conclusion massage after Taekwondo Training partially enhance immune function and reduce muscle pain, especially in kneading But further study needed to understand the exact mechanism relation to various massage treatment with exercise.
