It has been observed that the skill performance of Taekwondo athletes declines during the final third of each round, with this effect becoming more pronounced in the last round, thereby negatively impacting motor performance. This reduction in performance endurance limits athletes’ ability to compete successfully at both national and international levels.
To address this problem, the researcher designed endurance-based training programs supplemented with creatine monohydrate to evaluate their impact on selected physical and motor abilities in advanced Taekwondo athletes competing in the 54-58 kg weight category.
The aim of this study was twofold: (1) to develop performance endurance through a structured training program supported by creatine monohydrate supplementation, and (2) to identify differences in physical and motor performance variables between two experimental groups. It was hypothesized that the integration of endurance training with creatine monohydrate intake would positively affect the measured variables in both pre- and post-tests.
An experimental methodology was employed with two experimental groups to suit the research objectives. The study sample included 16 players from four clubs (Al-Shorta, Al-Karkh, Al-Amanah, and Al-Kahraba) who participated in the 2024 Iraqi Taekwondo Championship. Players were randomly assigned into two groups of eight athletes each. Following pre-testing, one group received performance endurance training with concurrent creatine monohydrate supplementation throughout the training program. Post-tests were conducted after the intervention, and the results were statistically analyzed.
The findings indicated that endurance training combined with creatine monohydrate supplementation produced significant positive effects on muscle cell adaptation and internal physiological systems, thereby enhancing both physical and motor performance.
The study concludes that implementing endurance training with nutritional supplementation positively develops physical variables and performance endurance in advanced Taekwondo players, particularly improving the execution of back and front circular kicks. The researcher recommends incorporating lactic acid-based dynamic endurance exercises into Taekwondo training curricula, as they are effective in enhancing both skill execution and physical capacity.
