The intensity, cardiorespiratory fitness and mental health benefits of integrated badminton teaching of “learning, practice and competition”: a quasi-experimental in university

Purpose: The "Learning, practice and competition" (L-P-C) is an important teaching method in the new round of school physical education curriculum reform in China. This study aims to explore the intensity characteristics of integrated of L-P-C badminton teaching and explore potential associations with changes in college students' cardiorespiratory fitness and mental health. Methods: ). Exercise intensity was quantified using Polar OH1 heart rate (HR) monitors, while cardiorespiratory fitness and mental health were evaluated by the 20-m shuttle run and the Symptom Checklist-90 (SCL-90) respectively, before the 1st and at the 16th weeks of the experiment. Results: = -0.69). Conclusion: This study suggests that the L-P-C badminton model primarily elicits moderate-intensity exercise, which is influenced by gender and skill levels. Participation in this integrated teaching model was accompanied by improvements in cardiorespiratory fitness and psychological well-being. However, due to the lack of a control group, these findings should be interpreted as associative rather than causal.
