Abstract

The purpose of the present study was to find out the effects of moderate and high intensity strength training and detraining on grip strength among school boys. To achieve the purpose of the study, the investigator selected 45 subjects. They were selected from the school boys, Kandigai, Chennai, Tamil Nadu. Their age ranged between 16 to 18 years. The randomly assigned in to three groups namely Group I underwent moderate intensity strength training, group II followed high intensity strength training and group three acted as control group. Each group consists of 15 subjects. The following variables on namely grip strength were selected for the study. They were tested with Grip Dynamometer. The training period was six weeks. To examine the effect of moderate and high intensity strength training on grip strength variable, Analysis of Covariance (ANACOVA) and Bonferroni test was applied as Post Hoc Test was used to assess the collected data. The data collected from both experimental groups and control group during posttest and during four stages of detraining were analysed by calculating Two way 3 x 5 Factorial ANOVA and Bonferroni test was applied as Post Hoc Test was used to assess the collected data. It was concluded that both experimental groups have significantly increased the grip strength as compared to control group. Further, the improvement of grip strength is significantly higher for high intensity strength training group than moderate intensity strength training group. The grip strength of moderate intensity strength training group has declined significantly with two cessations, where considerable decline is observed during the third cessation. The grip strength of high intensity strength training group has declined significantly with two cessations where considerable decline is observed during third cessation. The results of the study reveals that during detraining period, the gradual decline of grip strength for moderate intensity group is similar to high intensity group up to 15 days and maintained statistically significant differences. However, there is no significant difference between experimental groups after 20 days of detraining.
