A study of Training on the Circuit Type : On the Effect of the Body on Method under Submaximal Intensity (2)

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 31 items and the time of the training was set up to be lengthened 1.6 fold times of the total time required. Average values of training time (N=6) was 2130±283 seconds and average values of heart rate in training was 138.4±16.0 beats per minute (subj. T. K.), 138.4±14.5 beats per minute (subj. S. S.). Six male students aged 18-19 years were served as a training subjects and the other three male students aged 18-22 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 (L.) and side steps improved significantly by 3.4% and 2.6% respectively, while the change in tapping (R. and L.) and stepping (R.) did not change significantly. As for measurements of muscle strength, back strength, grip strength (R. and L.), knee extantion strength (R. and L.) and knee extantion strength per weight (R.) improved significantly by 1.7%, 4.8%, 3.6%, 3.8%, 3.0%, and 3.1% respectively. In measurements of anaerobic power, maximum power staircase, maximum power staircase per weight and vertical jump improved significantly by 4.6%, 4.5%, and 4.4% respectively. Average values of aerobic work capacity i. e. VO_2 max., VEmax. and O_2 pulse max. increased significantly by 3.1%, 2.8% and 3.0% respectively. VO_2 max. /wt., H. R. max. and O_2 removal did not change significantly. Anthropometric measure showed significant increase in chest girth, girth of upper arm on flexion (L.) and girth of fore arm (L.)
