초록

Pressurization training (PT) is designed to perform short term training using exclusive pneumatic belt applying pressure on upper parts of arms and legs to reduce blood flow to limbs. PT may be an appropriate tool for elderly, rehabilitating patients, non-fit people who could not tolerate high intensity training, and people who desire to improve physical fitness with low exercise intensity. However, it has not completely been proved whether PT could improve the physical fitness and skeletal muscle function. Elite snowboard athletes were recruited in this study. Subjects were 9 PT group (23.22 ± 1.43). All subjects completed 2 week training program. PT training program was consisted totally 9 sets, 20 repetition body squat, lunge, leg-extension(20% of 1RM) and 1-minute rest (twice a day and 6 days per week). Subject performed training with specially designed elastic band wrapped around both legs. Warm-up was performed for 30 seconds under pressure of 120 mmHg, and then the pressure was decreased to 0 mmHg for 10 seconds. After this warm-up, Subject continued body squat, lunge, leg-extension(20% of 1RM) with pressure increased gradually from 20 mmHg to 180 mmHg. On the first day, Training was performed under pressure of 100 mmHg, an then on the seven day, the pressure was increased by 10 mmHg during the training up to 180 mmHg. Pressure was maintained with 180 mmHg for the rest of training period. The result showed that LBM was significantly increased and cross sectional areas of quadriceps on both right and leg were increased by 2.0 and 3.0%, respectively. Strength of knee extension, flexor were increase (5%), Physical fitness significantly increased (16%). It is concluded that two-weeks term pressurization training could improve skeletal muscle function at low intensity and may also be a useful method to improve physical fitness such as muscle strength and muscle hypertrophy.
