Circuit training이 체력에 미치는 영향

The effect of circuit training on the physical fitness

&nbsp;&nbsp;The purpose of this study was to investigate the effect of circuit training on physical fitness and physical work capacity.<BR>&nbsp;&nbsp;20 physical education students at K university were divided into two groups ;<BR>&nbsp;&nbsp;One was the control group with 10 students and the orther was the training group with 10 students.<BR>&nbsp;&nbsp;circuit training was performed by 10 students of the training group, three a week for a period of 6 weeks.<BR>&nbsp;&nbsp;To evaluate the change of physical fitness, body weight, leg strength, arm strength, grip strength, back strength, power and agility were measured.<BR>&nbsp;&nbsp;The estimate the change of physical work capacity, all-out time, PWC&lt;SUB&gt;170&lt;/SUB&gt;, heart rate were measured by using a cycle Ergometer.<BR>&nbsp;&nbsp;The pre test was enforced before taking the experiment, the post test was operated after taking the experiment 6 weeks later.<BR>&nbsp;&nbsp;The results were as follows;<BR>&nbsp;&nbsp;1. No significant change was appeared in the body weight of each members in control group and training group.<BR>&nbsp;&nbsp;2. The back strengh and flexibility increased by 12.60 Kg (9.60%), 1.50㎝(7.37%) in the control group and training group was more increased by 22.60Kg (15.90%), 21.81Kg (15.00%) after 6 weeks.<BR>&nbsp;&nbsp;3. No significant change was appeared in grip strength and power in the control group, but training group was increased by 5.59Kg(11.12%), 3.70㎝(5.62%) after 6 weeks.<BR>&nbsp;&nbsp;4. The all-out time increased by 0.80minutes (9.76%) in the control group and training group was more increased by 1.50 minutes (14.88%) after 6 weeks.<BR>&nbsp;&nbsp;5. PWC170 increased by 0.51 minutes (8.40%) in the control group and training group was more increased by 1.05 minutes (13.13%) after 6 weeks.<BR>&nbsp;&nbsp;6. The heart rate during rest decreased by 1.50 beats/min (2.35%) in the control group and training was more decreased by 6.10 beats/min (9.77%) after 6 weeks.<BR>&nbsp;&nbsp;7. The maximum heart rate of exerercise increased by 1.80 beats/min (0.97%) in the control group and training group was increased by 2.70 beats/min (1.48%) after 6 weeks.<BR>&nbsp;&nbsp;8. The training group showed to have a decreased heart rate during exercise and recovery rather than the control group after 6 weeks.
