Introduction
The "Burn 2 Learn" (B2L) program, a school-based high-intensity interval training (HIIT) initiative, offers significant insights into the effective implementation of physical activity interventions for adolescents. As schools are ideal settings for promoting physical activity, understanding the process of implementing such programs can help practitioners optimize outcomes and overcome common challenges.
Key Findings from the B2L Program
The B2L program was evaluated through a cluster randomized controlled trial involving 20 secondary schools in New South Wales, Australia. The program aimed to enhance cardiorespiratory fitness (CRF) among older adolescents through teacher-facilitated HIIT sessions. The study revealed several critical findings:
- Implementation Fidelity: The program was implemented with moderate-to-high fidelity in Phases 1 and 2, but fidelity decreased in Phase 3. This highlights the importance of consistent support and monitoring throughout the intervention.
- Teacher and Student Engagement: Over 80% of teachers expressed an intention to deliver the B2L program to future cohorts, and nearly 70% of students intended to continue participating in HIIT. This suggests high satisfaction and perceived value of the program.
- Adaptability and Satisfaction: Teachers found the program adaptable to their school's context, and both students and teachers reported satisfaction with the intervention.
Implications for Practitioners
For practitioners looking to implement similar programs, the B2L study offers several valuable lessons:
- Focus on Fidelity: Ensure that interventions are delivered as intended, with regular monitoring and support to maintain high fidelity throughout all phases.
- Engage Teachers and Students: Building strong relationships with teachers and engaging students in the design and delivery of sessions can enhance motivation and sustainability.
- Adaptability is Key: Programs should be flexible enough to adapt to different school environments while maintaining core components that drive effectiveness.
Encouraging Further Research
While the B2L program provides a solid foundation, further research is needed to explore the long-term sustainability of such interventions and the impact of varying session intensities on health outcomes. Practitioners are encouraged to contribute to this growing body of research by evaluating and sharing their own experiences and findings.
