研究目的:

本研究的主要目的是在中心性肥胖成人中,比较总运动量匹配的累积式餐后抗阻训练、单次式餐后抗阻训练与不运动对照条件(静坐休息)对全餐次3小时餐后血糖增量曲线下面积的急性影响。次要目的是在同一人群中比较上述三种条件对24小时平均血糖、血糖变异性、主观食欲以及运动愉悦感与可接受性的影响。  

Objectives of Study:

The primary aim of this study is to compare the acute effects of accumulated postprandial resistance training, single-bout postprandial resistance training, and a no-exercise control condition (seated rest), matched for total exercise volume, on the all-meal 3‑hour postprandial glucose incremental area under the curve in adults with central obesity. The secondary aim is to compare the effects of the three conditions on 24‑hour mean glucose, glycemic variability, subjective appetite, and exercise enjoyment and acceptability in adults with central obesity.

药物成份或治疗方案详述:

1. 累积式餐后抗阻训练:参与者将在单日实验中进行三次各15分钟的餐后抗阻训练。每组训练将在每餐开始后30分钟内启动,运动时间与早餐、午餐和晚餐后的餐后时段保持一致; 2. 单次餐后抗阻训练:参与者将进行一次45分钟的餐后抗阻训练。本次训练将在早餐开始后30分钟内启动,其总训练量将与累积式组保持一致。 3. 控制组:参与者将按照相同的试验日流程进行操作并食用相同的标准化餐食,但不会进行有组织的运动;他们将在实验室中安排休息,并减少身体活动。 

Description for medicine or protocol of treatment in detail:

1. Accumulated postprandial resistance training (APRT): Participants will perform three 15-minute bouts of postprandial resistance training during a single experimental day. Each training bout will be initiated within 30 minutes of the start of each meal, thereby aligning exercise with the postprandial periods of breakfast, lunch, and dinner. 2. Single-bout postprandial resistance training (SPRT): Participants will perform one 45-minute bout of postprandial resistance training. This session will be initiated within 30 minutes of breakfast start and matched to the APRT condition for total training volume. 3. No-exercise control (CON): Participants will complete the same experimental day procedures and consume the same standardized meals, but will not perform structured exercise; they will be scheduled for rest in the laboratory and reduced physical activity. 

纳入标准:

Inclusion criteria

排除标准:

随机方法(请说明由何人用什么方法产生随机序列):

随机分配序列由主要研究者在受试者招募前使用计算机生成的随机数字表(Microsoft Excel RAND 函数)产生。受试者以 1:1:1 的比例被随机分配至三种试验条件的六种可能的平衡顺序之一:累积式餐后抗阻训练、单次式餐后抗阻训练和对照(静坐休息)。

Randomization Procedure (please state who generates the random number sequence and by what method):

The randomization sequence was generated by the principal investigator prior to participant recruitment using a computer-generated list (Microsoft Excel RAND function). Participants were randomly assigned in a 1:1:1 ratio to one of six possible counterbalanced sequences of the three experimental conditions: Accumulated postprandial resistance training, Single-bout postprandial resistance training, and Control (seated rest).

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

盲法:

单盲。受试者对治疗顺序设盲。结局评估者和数据分析人员对分组分配设盲。由于干预措施的性质,受试者和运动监督者无法对某一天执行的具体条件类型设盲。

Blinding:

Single-blind. Participants were blinded to the treatment sequence order. Outcome assessors and data analysts were blinded to group allocation. Due to the nature of the intervention, participants and exercise supervisors could not be blinded to the type of condition being performed on a given day.
