The study examined the effects of core training on unstable surfaces on sport performance among kayakers. The experimental group performed static unstable core training (SUCT), while the control group performed dynamic unstable core training (DUCT). The research focused on athletic performance and resistance training in the context of kayaking sport. The study was sponsored by Gao Jianxin and was successfully completed. The aim was to determine how different types of unstable core training affect kayakers' performance.
