Abstract:
Background: Time constraints comprise one limiting factor for implementing school-based physical activity programs. The aim of this pilot cluster randomized controlled study was to explore the effects of a cycle ergometer intervention during regular lessons on physical fitness, body composition, and health-related blood parameters. Methods: Participants attended one of 2 classes selected from one school, which were randomly assigned to an intervention group (n = 23, 11.2 [0.5] y) consisting of cycling on classroom-based ergometers during 3 lessons per week at a self-selected intensity and a control group (n = 21, 11.3 [0.5] y) not receiving any treatment. Prior to and after the 5-month intervention period, physical fitness (with ventilatory threshold as primary outcome), body composition, and parameters of glucose and lipid metabolism were assessed. Results: A significant time × group interaction was revealed for ventilatory threshold ( P = .035), respiratory compensation point ( P = .038), gross efficiency ( P 〈 .001), maximal aerobic power ( P = .024), triglycerides ( P = .041), and blood glucose levels ( P = .041) with benefits for the intervention group. Peak oxygen uptake and body composition were not affected. Conclusions: Children’s aerobic capacity benefited from the low-intensity school-based cycling intervention, while body composition and most blood parameters were not affected. The intervention using cycle ergometers is a feasible and time-saving strategy to elevate submaximal physical fitness.
