To assess the acceptance of the traditional American College of Sports Medicine (ACSM) exercise recommendation (20-60 min of vigorous exercise at least three times per week) and of the new, broader Centers for Disease Control (CDC)/ACSM physical activity recommendation (30 min of moderate intensity activities on most days of the week) in an obese population and to elucidate the implications of meeting these recommendations on weight reduction during dietary treatment.
Prospective dietary intervention study of 1000 kcal diet daily.
109 obese subjects (age: 45.6 +/- 13.1 y, body mass index (BMI): 38.1 +/- 6.0 kg/m2, (Female/Male: 81/19%)
The time spent in moderate (3-6 MET, metabolic equivalents) and vigorous (6-10 MET) physical activities was assessed by use of the Stanford-7-Day-Physical-Activity-Recall-Questionnaire, with subsequent allocation of the subjects to one of three physical activity groups: meeting the traditional recommendation (TR), the new recommendation (NR) or neither of both (SED, sedentary subjects). Physical activity level, physical activity energy expenditure, total energy expenditure (based upon the questionnaire) and resting metabolic rate (by standard equation) were estimated at baseline. Body weight was determined at baseline and after a mean of 16.3 weeks of dietary treatment.
The new, broader recommendation was met by twice as many of the obese subjects (34%) as was the traditional recommendation (17%). Weight reduction at follow up (-8.2 +/- 6.5 kg, 16.3 +/- 4.3 weeks, mean +/- s.d.) was positively correlated with the physical activity level at baseline (r = 0.49, P < 0.001). Meeting either the traditional or the new recommendation was associated with greater weight loss [-11.9 +/- 8.5 kg (TR) and -10.1 +/- 6.4 kg (NR), respectively, not statistically significant (NS)] as compared to being sedentary [-6.5 +/- 5.2 kg (SED), P < 0.05 vs both NR and TR].
Not only participation in vigorous exercise, but also regular engagement in moderate intensity physical activities, as recently recommended by the CDC/ACSM, predicts greater weight reduction during dietary treatment, compared to being sedentary. The new, broader physical activity recommendation appears to be more readily accepted by obese subjects than the former ACSM recommendation on exercise training.
评估肥胖人群对美国运动医学学院（ACSM）传统运动建议（每周至少三次，每次20 - 60分钟剧烈运动）以及疾病控制中心（CDC）/ACSM新的、更宽泛的身体活动建议（每周大多数日子进行30分钟中等强度活动）的接受程度，并阐明在饮食治疗期间达到这些建议对体重减轻的影响。
每日1000千卡饮食的前瞻性饮食干预研究。
109名肥胖受试者（年龄：45.6±13.1岁，体重指数（BMI）：38.1±6.0kg/m²，女性/男性：81/19%）
使用斯坦福7天身体活动回忆问卷评估中等强度（3 - 6代谢当量，代谢当量）和剧烈强度（6 - 10代谢当量）身体活动所花费的时间，随后将受试者分配到三个身体活动组之一：符合传统建议（TR）、符合新建议（NR）或两者都不符合（SED，久坐不动的受试者）。在基线时估计身体活动水平、身体活动能量消耗、总能量消耗（基于问卷）和静息代谢率（通过标准方程）。在基线时和平均16.3周的饮食治疗后测定体重。
符合新的、更宽泛建议的肥胖受试者（34%）是符合传统建议受试者（17%）的两倍。随访时体重减轻（-8.2±6.5kg，16.3±4.3周，均值±标准差）与基线时的身体活动水平呈正相关（r = 0.49，P < 0.001）。与久坐不动相比，符合传统或新建议均与更大程度的体重减轻相关[-11.9±8.5kg（TR）和-10.1±6.4kg（NR），分别无统计学显著性差异（NS）] [-6.5±5.2kg（SED），与NR和TR相比P < 0.05]。
与久坐不动相比，不仅参与剧烈运动，而且按照CDC/ACSM最近的建议定期进行中等强度身体活动，在饮食治疗期间预测体重减轻更多。肥胖受试者似乎比ACSM以前的运动训练建议更容易接受新的、更宽泛的身体活动建议。
