Effects of a 10-week active recess program in school setting on physical fitness, school aptitudes, creativity and cognitive flexibility in elementary school children. A randomised-controlled trial

The aim of this study was to assess the effects of a 10-week active recess programme in school setting on physical fitness, school aptitudes, creativity and cognitive flexibility in children. A total of 114 children (age range = 8-12 years old, 47.3% girls) participated in this study. The students were randomly assigned to two groups, experimental group (EG) and control group (CG). The EG performed a programme of physical exercise at moderate to vigorous intensity with cognitive engagement for 10 weeks, three times a week. Physical fitness, school aptitudes, creativity, and cognitive flexibility were tested. Non-significant differences were found in physical fitness (both pre-test and post-test) between groups. The EG experienced significant improvements in all school aptitudes, creativity and cognitive flexibility (TMT test). In addition, the EG showed greater increase (p<0.05) than the CG in all variables of school aptitudes (p<0.01), creativity (p<0.001) and cognitive flexibility (p<0.05). Significant correlation between ∆ TMT-B and ∆ V.O2max (r=-0.289, p=0.031) was found. In conclusion, active recess based on high intensity training can be a proper tool to improve some cognitive skills, such as school aptitudes, creativity, and cognitive flexibility.
