The Effect of a 4-Week Quick Strength Training Program on Body Composition, Strength, and Jumping Performance in Kickboxers

The aim of this study is to determine the effects of a four-week quick strength training program on body composition parameters, strength, and jumping performance in kickboxers. The study was designed as pre-test post-test experimental research with a control group, employing quantitative research methods. A total of 20 kickboxers (15.75±1.29), ten male and ten female, voluntarily participated in the study. The athletes were randomly assigned into two groups based on gender, with five athletes in each group: an experimental group (n=10) and a control group (n=10). The experimental group underwent quick strength training three times a week in addition to their routine kickboxing training, while the control group continued with only routine kickboxing training. Before and after the four-week training period, body composition analysis, countermovement jump (CMJ), back strength, and handgrip strength tests were conducted on the participants. The normality of the data was assessed using the Shapiro-Wilk test. For normally distributed data, the Independent Sample T-Test was used for comparisons between groups, while the Paired Sample T-Test was employed for within-group comparisons. According to the findings, significant improvements were observed in the back strength (t = -2.336; p = 0.044) and dominant handgrip strength (t = -2.877; p = 0.018) of the experimental group, favoring the post-test results. However, no statistically significant differences were found in CMJ, non-dominant handgrip strength, or body composition parameters between pre-test and post-test measurements (p0.05). As a result, it was determined that a four-week explosive strength training program had positive effects on back strength performance and dominant hand grip strength in kickboxing athletes.Keywords: Body Composition, CMJ, Strength, Quick Strength Training.
