Correlation between physical activity and motor skill among adolescents aged 12-14 / 中国学校卫生

Objective@#To explore the relationship between adolescents’ physical activity and motor skills, and to provide a new perspective for the promotion of adolescents physical activity.@*Methods@#The subjects were 153 adolescents aged 12-14, including 73 boys and 80 girls were selected as participants. The accelerometer (ActiGraph GT3X+) was used to measuring physical activity of the subjects for 7 consecutive days. The Movement Assessment Battery for Children, Second Edition (MABC-2) was used to measure the level of development of motor skills.@*Results@#The average time for subjects to participate in moderatetovigorous physical activity(MVPA) was 42.15 minutes per day, 15.7% of the subjects met the World Health Organization physical activity guidelines. 56% of subjects had an average level of motor development. There was a positive correlation between MVPA and the object control skill score(r=0.20, P<0.05). There was a positive correlation between low intensity physical activity and fine motor scores(r=0.23, P<0.01); There was a low correlation between moderatehigh intensity physical activity and object control in boys(r=0.29, P<0.05), and no correlation was found among girls.@*Conclusion@#Time spent in moderatetovigorous physical activity among adolescents is still insufficient. The mutual promotion of physical activity and motor skill provides a new perspective for developing the motor skills of children and adolescents to improve moderatetovigorous physical activity.
