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: A 16-week single-group pre-post experiment was conducted among 133 college students (average age: 18.08 ± 0.39 years, height: 167.23 ± 5.13 cm, BMI: 22.20 ± 3.60 kg/m Results: During the L-P-C, students primarily engaged in moderate intensity activity (52%). Compared with the "learning" and "practice", the "competition" phase demonstrated the highest proportion of moderate to high intensity activity (χ 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.
