Investigation of the Effects on Physiological Parameters of Football Players in Pre-season Period

The pre-season period in football is of great importance in order to optimise the performance of athletes and minimise the risk of injury. The aim of this study was to follow the physiological parameters of the athletes in the first pre-season preparation phase and to determine their readiness levels. Twenty-four professional licensed athletes aged between 18-35 (24.3±5.42) years participated in the study. The body weight and height of the athletes at the beginning of the season were 72.4±7.44 and 180.0±6.33, respectively. At the beginning and at the end of the first preparation phase, fat measurement, squat jump, overhead squat assessment and yo-yo endurance test were performed. The fat percentage obtained as a result of the tests was 7.43±0.73 in the pre-test and 6.99±0.65 in the post-test, 40.25±4.9 in the squat jump pre-test and 41.45±4.8 in the post-test, 17.33±3.5 in the overhead squat assessment pre-test and 19.50±2.1 in the post-test and 1723.3±307.6 in the squat jump pre-test and 1852.08±335.8 in the post-test. According to t-test data, statistically significant differences were found in fat percentage, squat jump, overhead squat evaluation and yoyo data ( .001). According to the results of the study, it can be said that the fat percentage, strength assessment, anaerobic power and endurance skills of the athletes improved in the first pre-season preparation phase.
