  • 摘要:Highlights • We examined reciprocal relationships between school physical activity and gross motor skills before and after a prolonged school break. • Gross motor skills, specifically ball skills, before summer break significantly predicted school physical activity after summer break. • The strength of the relationships tended to be stronger in females. • There was no evidence of bidirectionality in this relationship. Background Gross motor skills are postulated to have a bidirectional relationship with physical activity (PA); however, no study has tested this relationship before and after a summer break. The purpose of this study was to examine the bidirectional relationships between school PA and gross motor skills in children before and after a summer break. Methods Participants were a sample of 440 children recruited from 3 low-income schools (age = 8.9 ± 1.2 years, mean ± SD). PA was assessed as average school-day step counts using Yamax DigiWalker pedometers (Yamasa Tokei Keiki, Tokyo, Japan) worn for 5 consecutive school days. Gross motor skills were assessed using the Test for Gross Motor Development, 3rd edition. Data were collected at 2 timepoints: at the end of spring semester (T1) and at the beginning of the subsequent fall semester (T2). An age- and body mass index-adjusted cross-lagged model was employed to relate T1 school step counts with T2 gross motor skills and T1 gross motor skills with T2 school step counts. Results T1 gross motor skills significantly predicted T2 school step counts ( β = 0.24, 95 % confidence interval (95%CI): 0.08–0.40, p = 0.003); however, T1 school step counts did not predict T2 gross motor skills ( β = 0.04, 95%CI: –0.06 to 0.14, p = 0.445). The model explained 35.4% and 15.9% of the variances of T2 gross motor skills and T2 school step counts, respectively. Additional analyses indicated that these relationships were driven primarily by ball skills. Conclusion The relationship between gross motor skills and school PA was not bidirectional; however, higher gross motor skills, specifically ball skills, predicted higher school PA after a 3-month summer break.
