Cardiorespiratory fitness responses to a Daily Mile program in overweight youth from a low-income Colombian school.

Cardiorespiratory fitness significantly improved in the intervention group compared to controls following a 10-week Daily Mile program.

• The intervention group showed an average increase of approximately 150 m in the Shuttle Run Test compared to controls.
• Post-intervention Shuttle Run Test results: CG: 517.61 (71.93) m vs. IG: 400.00 (182.29) m, p = 0.028.
• Hierarchical multiple linear regression confirmed the intervention effect: β = 149.88; CI 95% 55.8–210.0, p = 0.002.
• The intervention group (n = 21) performed Daily Mile three days/week in addition to the usual curriculum; the control group had n = 24 participants.
• Participants were overweight and obese adolescents aged 11–17 from a low-income Colombian school.

No significant between-group differences were observed in anthropometry, blood pressure, muscular fitness, or baropodometry variables after the 10-week intervention.

• Outcomes assessed included anthropometry, blood pressure, muscular fitness, baropodometry, and cardiorespiratory fitness.
• The null findings across these measures were consistent between the intervention group (n = 21) and control group (n = 24).
• The study design was a parallel group experimental pilot study with random group assignment.

The study design was a parallel group experimental pilot study in overweight and obese adolescents from a low-income Colombian school.

• Participants were adolescents aged 11–17 randomly assigned to intervention or control groups.
• The intervention group (n = 21) performed Daily Mile three days per week in addition to the usual school curriculum for 10 weeks.
• The control group (n = 24) continued with the usual curriculum only.
• A hierarchical multiple linear regression was used to assess the intervention's effect on cardiorespiratory fitness.

The findings provide preliminary evidence of the feasibility of implementing the Daily Mile within a school routine in a low-income Colombian context.

• Authors describe the results as 'preliminary evidence of the feasibility of implementing DM within the school routine.'
• The authors note the findings 'support its potential to elicit favorable cardiorespiratory adaptations.'
• The authors call for 'further investigation in larger and longer-term studies in this context.'
