Six-month physical activity and fitness changes in Project Active, a randomized trial

摘要: Purpose: Project Active is a randomized clinical trial (N = 235) comparing lifestyle physical activity program with structured exercise in changing (total energy expenditure [kcal.kg -1 .d ]) and cardiorespiratory fitness (VO 2peak mL.kg - 1 .min ). Methods: Sedentary but healthy adults aged 35-60 years received 6 months of intensive intervention. Results: Analysis covariance (ANCOVA), adjusting for baseline measure, age, gender, body mass index (BMI), cohort, ethnicity, showed that at both groups significantly increased over (P < 0.001). The mean increases ±SE, 1.53± 0.19 kcal.kg the group 1.34±0.20 d group, were not different between 0.49). For fitness, had significant from Mean ± SE 1.58± 0.33 3.64 ±0.33 groups, respectively. This was greater We also studied changes intensity activity. Both moderate baseline, increase than 0.02). In contrast, its hard more difference 0.18).
