The study was conducted to see the effect of full squat training and half squat training over the isometric strength of quadriceps muscle and to see which squatting technique is better to develop maximal isometric strength of quadriceps muscles. Purposive sampling was used and pretest-posttest design was used. For this study 10 male participants 5 for full squat training and 5 for half squat training treatment, aging from 18 to 25 year were selected from the weight lifting match practice of L.N.I.P.E, Gwalior were selected. To check the effect of four week training program within the pretest and posttest of full squat Paired-t test was used and same was conducted for half squat and to check the effect of training program between both the groups Independent-t test was used by the means of SPSS software package. The level of significance was set at 0.05. To study the effect of the training program on athletes more precisely the muscular electric activity of the quadriceps muscle was also taken in consideration. The RMS value (Root Mean Square) was taken in account for statistical test of muscle electric activity. The comparison of muscle electric activity of both the groups was tested by Independent-t test by the means of SPSS software package. The level of significance was set at 0.05. Collegiate athletes (n = 10) completed four study visits, Pre-test and post-test and data collection of muscular electric activity. The collection of pre-test and post-test data was done by the standardized David F200 Quadriceps Extension machine. After the pre-test all the 10 subjects which were divided in two groups of 5 subjects in each group full squat and half squat were given training for 6 weeks on alternate days to provide 48 hours for recovery and growth process. In between the training process EMG (electro mayography) data of quadriceps muscles of both the groups was collected. After the 48 hours of completion of training program post-test was conducted and data was collected, researcher gathered the actual data of both the groups. On the day of Post-test, participants were informed the timing in advance to come in Bio-mechanical lab. However, there was significant increment in their score. So the conclusion was carried out that if we provide the full squat and half squat training to the athletes regularly, then it will bring 100 positive effect on the isometric strength of quadriceps muscles of the athlete and increase their performance and will definitely enhance their result. So the one Hypotheses out of three was rejected, but it may be concluded that squatting whether it is full squat or half will bring positive increment if isometric strength of quadriceps muscles.
