Abstrakt: | Background: Physical activity (PA) interventions in people with spinal cord injury (SCI) have been limited by a shortage of (1) evidence for sufficient increases in unsupervised PA to improve aerobic fitness and (2) stakeholder involvement in intervention design. Objectives: This study examined the effects of a theory-based PA intervention, developed in collaboration with nearly 300 stakeholders, on PA levels, aerobic fitness, and psychosocial predictors of PA among individuals with SCI. Methods: A randomized controlled trial (RCT) was conducted with 28 men and women with chronic SCI (age 45.0 ± 11.5 years, years post-injury 16.4 ± 12.4). Participants randomized to the intervention group (n = 14) received an introductory personal training session followed by eight weekly 15-min PA behavioral coaching sessions per week. PA was assessed using self-report and accelerometers. Aerobic fitness and psychosocial predictors of exercise were evaluated using an incremental exercise test and survey methods, respectively. Results: At post-intervention, controlling for baseline, the intervention group showed fivefold greater self-reported moderate to vigorous physical activity [mean difference 247.9 min/day; 95% confidence interval (CI) 92.8–403.1; p = 0.026, d = 1.04], 17% greater accelerometer-measured PA (mean difference 3.9 × 105 vector magnitude counts; 95% CI 1.1 × 104–7.7 × 105; p = 0.014, d = 0.31), and 19% higher peak oxygen uptake (VO |
