강도별 진동운동시의 에너지 대사 변화 = The Changes metabolism During Whole-Body Vibration Exercise in Each Level of Intensity

다국어 초록 (Multilingual Abstract)

This research conducted whole-body vibration exercise in the intensity of 20Hz, 26Hz, and 32Hz in diverse positions (5 minutes of standing position, 2 minutes of squatting position, 2 minutes of squatting and heel position, and 2 minutes of sitting down and bending the upper body; total of 11 minutes per set) on 18 male and female university students, utilizing whole-body vibration equipment, which is a new type of isometric contraction equipment, to investigate about the changes in energy Metabolism. And to submit the necessary data for whole-body vibration training program development, the research measures oxygen uptake, heart rate, blood pressure, blood lactate concentration, total cholesterol and norepinphrine change. Following are the results. 1. With 9㎖/min of average oxygen intake during the whole-body vibration exercise, there was no significant difference on the intensity levels, and the level of energy metabolism corresponding to around 31.0% of the oxygen uptake during the maximum exercise of bicycle ergometer was shown. 2. The average heart rate during the whole-body vibration exercise was proven to be around 108 beats/min with no significant difference among the intensity levels, and the energy metabolism corresponding to around 58% of the heart rate during the maximum exercise of bicycle ergometer was shown. 3. The average systolic blood pressure during the whole-body vibration exercise was proven to be 165mmHg with no significant difference among the intensity levels, and it corresponded to around 83% of the blood pressure during the maximum exercise of bicycle ergometer. Furthermore, the average of the diastolic blood pressure was proven to be 98mmHg without any significant difference among the intensity levels, and it corresponded to around 97% of the blood pressure during the maximum exercise of bicycle ergometer. 4. The average of blood lactate concentration during the whole-body vibration exercise was 1.6mmol/ℓ without any significant difference among the intensity levels, and energy metabolism level of around 27% of lactate concentration was shown during the maximum exercise of bicycle ergometer. 5. The average of total cholesterol and norepinephrine after to the whole-body vibration exercise was increased significantly. Through the results driven as above, we were able to learn that the energy metabolism during the 22 minutes-long whole-body vibration exercise in 20Hz ~ 32Hz in each position was conducted in the level of the aerobic, regardless of the intensity of exercise, and total cholesterol, catecholamine and blood pressure significantly increased post to the exercise.
