研究在肥胖干预期间18个月时，体力活动（PA）变化是否与中等强度至高强度PA（MVPA）能量消耗和体重指数（BMI）相关。纳入6个月时MVPA ≥ 10分钟/周且PA数据完整的受试者。参与者被分为品种（N = 30），≥ 2种不同的活动/周，或较少品种（N = 65），只有1种活动/周。在18个月时，每周MVPA相关的能量消耗对于品种比品种少的品种更高（3674.7 ± 1934.6 kcal/周vs 2197.3 ± 1841.4 kcal/周，p <0.05），BMI没有差异。肥胖治疗期间每周PA变化较大与18个月MVPA能量消耗较大相关。
To examine if physical activity (PA) variety was associated with moderate- to vigorous-intensity PA (MVPA) energy expenditure and body mass index (BMI) at 18 months during an obesity intervention. Participants with ≥ 10 minutes/week of MVPA at 6 months and complete PA data were included. Participants were classified into Variety (N = 30), ≥ 2 different activities/week, or Less Variety (N = 65), only 1 activity/week. Weekly MVPA-related energy expenditure was higher for Variety than Less Variety (3674.7 ± 1934.6 kcal/week vs 2197.3 ± 1841.4 kcal/week, p < .05) at 18 months, with no difference in BMI. Greater weekly PA variety during obesity treatment was related to greater 18-month MVPA energy expenditure.
