Effect of Strength, Endurance and Concurrent Training on selected Bio-Motor Variables of Middle Distance Runners

The purpose of the study was to find out the effect of strength, endurance and concurrent training on selected bio-motor variables of middle distance runners. To achieve the purpose of the present study, sixty middle distance runners from affiliated colleges of University of Madras, Chennai, Tamilnadu, India were selected as subjects at random and their ages ranged from 18 to 28 years. The study was formulated as a true random group design, consisting of a pre-test and post-test. Sixty middle distance runners from affiliated colleges of University of Madras, Chennai, Tamilnadu, India was selected as subjects at random and their ages ranged from 18 to 28 years. The subjects (N=60) were randomly assigned to four equal groups of fifteen subjects each. Pre test was conducted for all the subjects on selected bio-motor variables. This initial test scores formed as pre test scores of the subjects. The groups were assigned as Experimental Group I, Experimental Group II, Experimental Group III and Control Group in an equivalent manner. Experimental Group I was exposed to strength training, Experimental Group II was exposed to endurance training, Experimental Group III was exposed to concurrent training and Control Group was not exposed to any experimental training other than their regular daily activities. The duration of experimental period was 12 weeks. After the experimental treatment, all the sixty subjects were tested on their bio-motor variables. This final test scores formed as post test scores of the subjects. The pre test and post test scores were subjected to statistical analysis using Analysis of Covariance (ANCOVA) to find out the significance among the mean differences, whenever the ‘F’ ratio for adjusted test was found to be significant; Scheffe’s post hoc test was used. In all cases 0.05 level of confidence was fixed to test hypotheses. The concurrent training had shown significant improvement in speed and agility than the strength training, endurance training and control groups
