The purpose of the study was to find out the effect of different intensity circuit training and detraining on selected physiological parameter (Vital index). To achieve the purpose of the study, 45 untrained male students from the Department of Physical Education and Sports Sciences, Annamalai University were selected t random as subjects from volunteers, in the age group of 18 to 20 years. The chosen subjects were randomly assigned into three groups of 15 each. Group I underwent moderate intensity circuit training, group II followed high intensity circuit training and group III acted as control subjects. The intensity of exercise was progressively increased once in two weeks. After the completion of ten weeks of moderate and high intensity circuit training periods, the subjects of both experimental groups were physically detrained for 40 days. During the detraining period both the experimental groups were ceased their circuit training and became inactive. They have not participated in circuit training or in any other strenuous physical exercise throughout the detraining period and they were under the control of the investigator. During the 40 days of detraining period, the data were collected for all the variables, once in ten days for four detraining periods for both experimental groups and control group. Both experimental groups have significantly increased the vital index as compared to control group. Further, the improvement of vital index is significantly higher for high intensity group than moderate intensity circuit training group. During detraining period, the gradual decline of vital index for moderate intensity group is similar to high intensity group. However, there is no significant difference between experimental groups during all the cessation periods.
