Efficacy of Core Strength Exercises in Enhancing Rebound Jump Performance in Martial Arts Athletes

Abstract

Background and Aim: Core strength exercises have become a focus in sports performance and injury prevention research. The core muscles, which include the diaphragm, abdominal muscles, and pelvic floor muscles, are instrumental in providing stability and power during athletic activities. The study focuses on the impact of core strength exercises on specific performance metrics—namely, the standing long jump and rebound jump—in martial arts athletes. Materials and Methods: The study employs a structured, eight-week intervention program to investigate the effects of core exercises on martial arts athletic performance. The study involves forty student-athletes from Guangzhou Sport University, divided into an Experimental Group (EG) and a Control Group (CG). Various physical tests are conducted both pre- and post-intervention to measure the effects. Statistical analyses, including Two-way ANOVA, are used to interpret the data. Result： For the standing long jump, the Two-way ANOVA showed no significant effect of training (F=1.129, p=0.291) or time point (F=0.587, p=0.446). Effect sizes, measured by Cohen's d, indicate a slight benefit in the core reinforcement group with a value of d=0.425, compared to d=0.111 in the non-reinforcement group. In the case of the rebound jump index, there is a pronounced effect from the group (F=4.92, p=0.03) and the time point (F=105.97, p<0.001). Large effect sizes were observed, with d=2.5522 for the core reinforcement group and d=2.0457 for the no core reinforcement group. Conclusion: For standing Long Jump: Given the absence of a significant impact of core reinforcement on this metric, coaches, and athletes might consider incorporating other methodologies, such as plyometrics or attentional focus strategies, into their training regimen. For the rebound Jump Index: Core reinforcement exercises should be strongly considered for inclusion in warm-up routines for martial arts athletes, given the substantial effect size observed.
