Effects of long-term low intensity aerobic training and detraining on high density Lipo protein in men and women students
Dr. W Vinu
The experimental design used for this study was similar to a random group design. It consisted of two different populations namely men and women students. Fifteen men subjects and fifteen women subjects were selected randomly from the above population. All the two experimental groups underwent low intensity aerobic training and were tested prior to and immediately after the experimentation on serum lipoprotein. To find out the detraining effect the blood samples were collected and tested onhigh density lipoprotein once in a week (Five Times) after the regular low intensity aerobic training for16 weeks. The data collected from experimental group I and group II prior to and after the completion of the training period were statistically analysed for significant difference if any, by applying dependent ‘t’ test. To eliminate the influence of pretest, the net mean gains of experimental groups were computed separately. The paired mean gains of experimental groups were tested for significance by applying independent ‘t’ ratio. Repeated measures of ANOVA were used to find out the detraining effect of group I and group II. Whenever the 'F' ratio was found to be significant, Scheffe’s test was used as post-hoc test to determine which of the paired means differed significantly. The level of confidence was fixed at 0.05 levels. the results of the study indicate that low intensity aerobic training increase high density lipoprotein for all the two groups namely men and women groups. It also indicated that the increase for men was greater than women group. Both men and women group showed significant increase in high density lipoprotein the results of the study indicate that the five weeks of detraining progamme, (after the 16 weeks’ low intensity aerobic training) decrease the HDL-C level among the men and women groups.
