description: The C-level difficulty movement refers to the complicated jumping movement stipulated in the wushu rules of the competition set. This study examines the effect of 12 weeks of core strength training on C-level difficulty movements of routine wushu athletes. Forty-two elite wushu athletes, twenty-one 21 in the experimental and 21 in the control groups, respectively, were randomly selected for this study. The core strength training intervention imitated the movement modes of wushu athletes, run-up, take-off, air spin, landing stability. In this study, the control group followed the routine training designed by the wushu training center. The experimental group completed 12 weeks of core strength training, 30 minutes per week, and three tests. The pre-test’ was conducted before starting the intervention (week 0), the second test (week 6), and the third test (week 12). For the variables in terms of run-up, take-off, air spin, and landing stability of the Whirl Wind Kick at 720°, the GEE results of the participants revealed that the group had a substantial effect. These results indicate that there was a statistically significant difference in the run-up performance between the groups (c2=672,988, p&lt;0.001), take-off (c2=787.728, p&lt;0.001), air spin (c2= 310.456, p&lt;0.001), and landing stability (c2=784,774, p&lt;0.001), respectively.Methods Research design A cluster randomized controlled trial (CRCT) was employed in this study. A CRCT is a method of evaluating the impact of a program or policy intervention in which the population receiving the intervention is chosen randomly from the eligible population, and a control group is also chosen randomly from the same eligible population(White et al., 2014). One of its strengths is that it provides a potent response to questions of causality, allowing evaluators and program implementers to know the result of the intervention and nothing else(White et al., 2014). Meanwhile, CRCT can demonstrate that a new treatment is superior to the current standard treatment. CRCTs of high quality with a low risk of systematic error (bias) provide the strongest evidence(Puffer et al., 2005). Therefore, CRCT is the gold standard for ascertaining treatment efficacy and safety(Kabisch et al., 2011).This study was conducted in Yinchuan, Ningxia, China. There are two professional wushu training bases in Ningxia, namely Ningxia wushu Professional Training Base and Ningxia Children’s Palace, where there are many elite athletes. At the same time, the coaches of the two training bases have national coach certificates. Therefore, the two sites were randomly divided into the control group and the experimental group. In addition, the researcher has experience of learning at the site and is familiar with the facilities (Zhou, 2019).The sample size is closely related to statistical power, which is the ability of a study to detect a statistically significant difference. There is a compensation relationship between the size of feasible samples and the appropriate statistical power(Eng, 2003). A priori power analysis based on two-way repeated measure ANOVA was performed using G-power software Version 3.1 to estimate the required sample size. The sample size was calculated with a medium effect size (f = 0.24)(Huh, 2021), setting α = 0.05, power (1-β) = 0.8, number of groups = 2, and number of measurements = 3, the total required sample size estimated as n = 38 subjects.Obtaining informed consent from participants is an ethical obligation for all social science research.
