Investigation of the effect of contrast training method on the performance of boxers related to strength and speed

The aim of this study is to investigate the effect of force and speed on right-left straigth punch speed performances by applying contrast training method to athletes. As a result of the 6-week contrast training conducted in the research, the maximal force, explosive force and punch speed performances, which are one of the most important determinants of boxers' performance, were examined. 16 National amateur boxers participated in the study. Demographic information and Anthropometric measurements of all boxers were recorded (Age, Height, Body weight, body mass index, skeletal muscle mass, body fat percentage). The study was conducted in two groups: Contrast training group (CTG) and control group (CG). The Contrast Training group continued their routine training for 6 weeks in addition to the Contrast training, which was practiced 3 days a week. The control group continued their routine boxing training. The participants came to both measurement days. The measurement on the first day, participants anthropometric measurements, the maximum 1 Rep (1RM) values and Maximum bounce Heights are determined and squat, squat 1 Rep Maximum after giving enough rest (1RM) values and bench presses Tendo power and speed Analyzer device and right-left straight punch speed test results were obtained. at the end of the 6-week study, the second measurements were performed as on the first measurement day, following the standard warming protocol, tests were performed and data were recorded. The principle of study of contrast loading is that a high-weight (80%>) series is applied interchangeably with a light-weight (40-50%) series. An explosive application of movement is highlighted in the light series. The data obtained were evaluated in a computer environment using the SPSS 22 statistical package program. In this study, the confidence december was accepted as 0.05. As a result, in this study, a statistically positive significant difference was found in the results of pre-test and post-test measurement of the group applying the contrast training method in punch speed performance compared to the control group. In the study, a significant change was found in Bench press, Squat and Squat jump in both groups dec comparisons between the groups. As a result dec while there was a statistically significant difference between the maximal strength and squat jump of the different training methods applied in both groups, no significant difference was found between the training methods applied.
