The practical application of the Canadian Agility and Movement Skill Assessment (CAMSA) has been reported in some Western countries. However, a few studies reported the application of the CAMSA in Chinese children. In addition, given that the CAMSA was designing to incorporate both movement skills and agility assessment, the value and validity of the timing component of the CAMSA are worth discussing.
By choosing the Illinois Agility Test, Repeated Side Step-1 m distance, and the newly designed Repeated Side Step-half of height as the benchmark, we evaluate the performance of the CAMSA, further establish the concurrent validity of the CAMSA timing components (completion time and time score). In total, 149 male children (mean age 9.0 ± 0.8 years) from public schools in Shanghai, China, participated in the study.
The mean CAMSA completion time was 19.3 ± 5.3 (s), and mean time score was 8.7 ± 3.9 (range of 1-14) for all participants ( = 149). After adjusted the sprint speed, older age was positively associated with the performance of the CAMSA. Being overweight was not associated with the performance of the CAMSA comparing with healthy body mass children, however, being obese was negatively associated with the CAMSA timing components and total score. Children having extracurricular sports activities (e.g., athletic experiences), mostly soccer, were more likely to demonstrated better performances of the CAMSA completion time, time score and total score. However, overweight and obese, also athletic experiences were not significantly contributed to the CAMSA skill score, although the association was slight (Adj = 0.13). Besides, the CAMSA completion time has a strong correlation with the IAT, = 0.77; RSS-1MD, = - 0.76; and RSS-HHD, = - 0.77, < 0.01. The same pattern of correlation was also found between the CAMSA time score and three agility tests: IAT, = - 0.79; RSS-1MD, = 0.76; RSS-HHD, = 0.78, < 0.01.
Overall, a few participants in the study were able to reach the recommended level of the total CAMSA score referring to the Canadian criterion. The strong concurrent validity was found between the CAMSA timing components and three selected agility tests, respectively.
加拿大敏捷与运动技能评估(CAMSA)在一些西方国家已有实际应用的报道。然而,仅有少数研究报道了CAMSA在中国儿童中的应用。此外,鉴于CAMSA旨在综合运动技能和敏捷性评估,CAMSA计时部分的价值和有效性值得探讨。
选择伊利诺伊敏捷性测试、1米距离重复侧步以及新设计的身高一半重复侧步作为基准,评估CAMSA的表现,进一步确立CAMSA计时部分(完成时间和时间得分)的同时效度。共有149名来自中国上海公立学校的男童(平均年龄9.0±0.8岁)参与了该研究。
所有参与者(n = 149)的CAMSA平均完成时间为19.3±5.3(秒),平均时间得分为8.7±3.9(范围为1 - 14)。在调整短跑速度后,年龄较大与CAMSA表现呈正相关。与健康体重儿童相比,超重与CAMSA表现无关,然而,肥胖与CAMSA计时部分和总分呈负相关。参加课外活动(如体育经历),主要是足球的儿童,更有可能在CAMSA完成时间、时间得分和总分方面表现更好。然而,超重和肥胖以及体育经历对CAMSA技能得分的贡献并不显著,尽管这种关联很轻微(调整后R² = 0.13)。此外,CAMSA完成时间与IAT的相关性很强,r = 0.77;与RSS - 1MD的相关性为r = - 0.76;与RSS - HHD的相关性为r = - 0.77,P < 0.01。在CAMSA时间得分与三项敏捷性测试之间也发现了相同的相关模式:与IAT的相关性为r = - 0.79;与RSS - 1MD的相关性为r = 0.76;与RSS - HHD的相关性为r = 0.78,P < 0.01。
总体而言,参考加拿大标准,该研究中只有少数参与者能够达到CAMSA总分的推荐水平。分别在CAMSA计时部分与三项选定的敏捷性测试之间发现了很强的同时效度。
