In this study, the effect of leg press workouts on leg strength applied three times a week for eight weeks has been investigated. 26 male students from the School of Physical Education and Sports at Erciyes University between the ages of 18-25 who have not been regularly following a training scheme voluntarily participated in this study. Volunteers were divided into two groups. By using the pyramidal training method, the first group worked out leg press at 90 degrees, and the second group 120 degrees three times a week for eight weeks. Birth certificate was accepted as the on criterion for determining age. Measurements of stature, body weight, leg height and thigh were performed. Body mass index and body fat percentage were calculated with a formula. To determine to the strength of legs, measurements were taken for standing long jump, and vertical jump; and also Tanita dynamometer was used. Data collected through measurements have been analyzed with IBM SPSS Statistics version 22. In the determining the difference between pre and post values within groups, t test was used in dependent groups; while in the comparison of intergroup, t test was applied in independent groups. p<0.05 was considered significant. At the end of the study, when measurement values were compared for pre and post training results; decrease in body fat percentage and increase in thigh mass, standing long jump and Tanita measurements were statistically significant (p<0.01), while in other variables they were found to be insignificant (p>0.05). In conclusion, the results obtained showed that doing leg press at 90 and 120 degrees three times a week for eight weeks has an effect in increasing leg strength.
