- a one-time covariate defined at baseline
- b The OR (95% CI) for the exercise intervention (150, 200 or 300 minutes/week) versus the control group was 1.26 (0.74, 2.13), p = 0.40 for any injury/illness attributed to exercise and 1.24 (0.68, 2.25), p = 0.49 for lower body musculoskeletal injury attributed to exercise.
- c time-varying covariate defined at months 6, 12, and 18
- d centered at 30
- e Controlling for race and randomized exercise intervention, the odds of injury (95% CI) over time for overweight (BMI 25-29.9 kg/m2) and obese (BMI > 30 kg/m2) participants were 1.65 (1.00, 2.70) and 1.89 (1.06, 3.33) for any injury and 1.53 (0.89, 2.63) and 1.28 (0.67, 2.47) for lower body musculoskeletal injury attributed to exercise, respectively, compared to participants who achieved BMIs < 25 kg/m2.
