Relationship Between Factors Associated With School Environment & Compliance With Physical Activity Recommendations < Schoolchildren

Abstract

RESULTS:Twenty-seven studies (635 participants) were included. A significant difference was found for same-day PPG control, which favored accumulated exercise over one bout of energy-matched continuous exercise (SMD −0.36 [95%CI: (−0.56, -0.17)], P=0.0002, I 2 =1%), specifically in accumulated exercise with PA breaks (SMD −0.36 [95%CI: (-0.64, -0.08)], P=0.01, I 2 =30%), low-moderate intensity exercise (SMD −0.38 [(95%CI: (-0.59, -0.17)], P=0.0005, I 2 =0%), and in non-diabetic populations (SMD -0.36 [95%CI: (-0.62, -0.10)], P=0.007, I 2 =16%). No differences were found for same-day postprandial insulin and triglycerides, or second-morning effects for all previously mentioned markers between different exercise patterns. CONCLUSIONS:Compared with one session of continuous exercise, accumulated exercise-specifically in subgroups of PA breaks, low-moderate intensity exercises-produced greater acute effects on same-day PPG control for non-diabetic adults. There were no differences between continuous and accumulated patterns of exercise in terms of same-day postprandial insulin and triglycerides and second-morning effects.
