サーキット式トレーニングの検討 : Submaximalな強度での実施が身体に及ぼす影響について(1)

Abstract

The purpose of this study is to investigate how the circuit-training method under submaximal exertion has an effect on the body. The circuit-training consists of 18 items and the time of the training was set up to be lengthend 1.5 fold times of the total-time required. Average values of training time (N=6) was 1647±36 seconds and average values of heart rate in training (N=4) was 148.4±15.3 beats per minute. Six male students aged 18-22 years were served as a training subjects and the other two male students aged 22 years were served as a control subjects. The training were had for 3 times per a week during 6 weeks. The results obtained were as follows. In measurements of the agility, stepping (R. and L.) and side steps improved significantly by 3.3%, 3.9% and 4.5% respectively, while the change in tapping (R. and L.) did not change significantly. As for measurements of muscle strength, back strength, grip strength (R. and L.), elbow flexsion strength (R. and L.) and pectoralis major strength (R. and L.) improved significantly by 3.7%, 4.6% 6.4% 4.2%, 3.4%, 11.8% and 13.0% respectively. In measurements of anaerobic power, maximum power staircase and maximum power stircase per weight improved significantly by 6.9% and 5.1% respectively. Average values of aerobic work capacity i.e. VO_2 max., VO_2 max./wt, VE max., O_2 pulse max. increased significantly by 5.3%, 3.8%, 5.1% and 5.6% respectively. H.R. max. and O_2 removal did not change significantly. Anthropometric measure showed significant increase in girth of upper arm on flexion (R), girth of fore arm (R. and L.) and girth of thigh (R).
