Study On The Application And Performances Of The Canadian Agility And Movement Skill Assessment (CAMSA) In Elementary School Children

Purpose:As a newly developed protocol,Canadian Agility and Movement Skill Assessment(CAMSA)is based on the dynamic situation to make a comprehensive evaluation of the agility and fundamental movement skill proficiency of children and adolescents.However,most of the study participants recruited from Canada,Australia,and other western countries at present,and there are few studies on the application of the CAMSA in China.Therefore,the purpose of this study is to conduct the CAMSA for elementary school students in Shanghai,China,and evaluate the performances,also establish the reliability evidence of the CAMSA.Besides,we want to determine the influencing factors of CAMSA performances to provide theoretical support for improving children's dynamic movement skills ability.Methods:In total,225 elementary school students aged 8-10 from Shanghai participated in the study,in which 179 participants were regular students(boys and girls of healthy body mass,overweight,obesity)who do not have extracurricular sports activities except the school PE class.Besides,46 participants were school soccer team members(all boys of healthy body mass).The study carries out the CAMSA for all the students,which also conducts a re-test on the same day.Four professional raters assisted in the study.The index we selected covers the age,gender,body composition(Body Mass Index,BMI),agility(Illinois Agility Test,IAT),coordination(one-minute rope skipping),and speed(50 meters sprinting).Results:? Only 11 of the 179 regular students were able to meet the recommended level of the CAMSA total score referring to the Canadian norm,and it was more difficult for girls to meet the recommended level(OR=0.17,95%CI=0.05,0.61).On the 46 soccer players,only 5 of them were not able to meet the recommended level of the CAMSA total score.Besides,All study participants performed poorly in the throwing skills among seven CAMSA skills;in particular,it is difficult for study participants to complete "throwing and hit the target accurately."? When comparing regular students(boys)and soccer players,the study found that there were significant main effects in age and groups for the CAMSA time score and total score.While in the skill score,the difference between the two groups decreases with the growing age.? In regular students,age had a significant positive effect on the CAMSA total score(P<0.05).Compared with healthy body mass participants,obese participants were more likely to demonstrate lower CAMSA total score(P<0.05),while overweight participants have no significant disadvantage on CAMSA total score(P>0.05).The agility in the form of IAT had significant effects on CAMSA time score(P<0.001,Adj R2=0.50),skill score(P<0.001,Adj R2=0.20),and total score(P<0.001,Adj R2=0.48).The coordination and speed in 7 the form of one-minute rope skipping and 50 meters sprinting had no significant effects on each component of the CAMSA(P>0.05).? In soccer team members,participants with older age and better IAT performances were more likely to demonstrate a higher CAMSA time score(P<0.05,Adj R2=0.51)and total score(P<0.05,Adj R2=0.28).However,age and the agility had no significant effects on the CAMSA skill score(P>0.05).Both the coordination and speed had no significant effects on each component of the CAMSA(P>0.05).? Participants performed significantly better CAMSA time score and total score on the second test,e.g.,re-test(P<0.05).There were no significant differences in skill score between the first test and second(P=0.478,95%CI=-0.34,0.16).Moreover,the inter-rater reliability of CAMSA skill score was substantial(ICC>0.6)for four raters.Conclusion:The Canadian Agility and Movement Skill Assessment is a feasible measure of dynamic movement skills ability for students in Shanghai.Although few participants can meet the recommended level set in the Canadian norm,the CAMSA itself shows substantial reliability.What is more,it exists significant age and gender effects in CAMSA performances in which girls had a lower score than boys.Children with obese performed weaker than children with healthy body mass in CAMSA total score.Soccer team members performed better than regular boys in CAMSA total score.The agility in the form of IAT had a significant positive effect on the CAMSA performances.
