Abstract

Research Problems: The kicking technique in taekwondo is predominantly utilized, necessitating significant leg muscle power to achieve optimal performance. Taekwondo is closely associated with weight categories in competitions. Body composition and leg muscle power are important factors in implementing the correct techniques for kicking and leg movements. Research Objectives: This study aims to determine the relationship between body composition and leg muscle power among East Java taekwondo athletes. Methods: The participants in this study included 51 East Java taekwondo athletes, comprising 27 male and 24 female athletes. Data were collected through body composition measurements using Bioelectrical Impedance Analysis (BIA) and the Countermovement Jump (CMJ) test to measure the leg muscle power of taekwondo athletes. This study employs a descriptive quantitative research design with a cross-sectional approach. Results: A significant relationship was found between body weight, height, Fat-Free Mass (FFM), Skeletal Muscular Muscle Mass (SMM), and Percent Body Fat (PBF) with leg muscle power and jump height, with a p-value <0.001. Conclusion: Body composition significantly influences leg muscle power, which in turn supports the performance of taekwondo athletes in jumps and kicks.

Methods: this systematic review protocol adheres to the PRISMA 2020 guidelines. A systematic search was conducted using the popular databases Scopus, ScienceDirect and PubMed published between 2020 and 2025. The search was conducted on peer reviewed articles written in English, and reported on the condition of pre-competition anxiety on competition performance in young athletes aged 12-18 years who competed in professional events. Result: Of the total 975 publications initially identified, 9 studies met the selection criteria for inclusion in this review. These articles explored the effects of pre-competition anxiety on sports performance across various athletic disciplines. The studies provided insights into varying levels of pre-competition anxiety, different interventions aimed at reducing anxiety, and their subsequent effects on performance outcomes. The findings suggest that pre-competition anxiety can significantly impact performance, with both positive and negative effects depending on the anxiety level and intervention methods employed.
