Effect of Instability Resistance Training on Balance, Core Muscle Strength, and Athletic Performance

The goal of this experimental study is to examine the effect of instability resistance training (IRT) on balance ability, core muscle strength, and athletic performance of young Chinese male kayak canoeists. The main questions it aims to answer are: Do the IRT and TRT methods have any effect on the subject's balance ability in terms of static balance and dynamic balance? Do the IRT and TRT methods have any effect on the subject's isometric strength of the core muscle group in terms of abdomen, back, left lateral, and right lateral? Do the IRT and TRT methods have any effect on the subject's isotonic strength of the core muscle group in terms of flexion, extension, left lateral flexion, and right lateral flexion? Do the IRT and TRT methods have any effect on the subject's athletic performance in terms of dynamometer performance and calm-water performance? Researchers will compare the effect of instability resistance training (IRT) and traditional resistance training (TRT) on balance ability, core muscle strength, and athletic performance of young Chinese male kayak canoeists. Participants will: Take 12-week instability resistance training (IRT) and traditional resistance training (TRT) difficulty level (primary level 1-4 weeks, intermediate level 5-8 weeks, and advanced-level 9-12 weeks). Take 3 training sessions per week and complete the training on Mondays, Wednesdays, and Fridays from 4 to 5 pm.
