简要总结
This experimental study investigates the acute cardiovascular and local recovery to a single session of resistance training, with and without additional static stretching, compared with a resting control condition. Participants are allocated to one of three groups (control, resistance training, resistance training plus static stretching) and assessed at baseline, immediately after the session, and 30 minutes post-exercise. Primary outcomes include rate-pressure product and local muscle oxygen saturation, while secondary outcomes include heart rate, blood pressure, brachial artery diameter, tissue hardness, and pressure pain threshold. These measures are used to characterize the short-term effects of the different experimental conditions on systemic hemodynamic load, vascular response, local muscle oxygenation, mechanical tissue status, and pressure pain sensitivity during early recovery.

结局指标
主要结局
Rate-Pressure Product (RPP)
时间窗: 3 times (Baseline, immediately after intervantion and 30 minutes after intervention) for each condition (CC, RT, RT+ST)
Rate-pressure product (RPP) will be used as an index of myocardial workload and hemodynamic load during early post-exercise recovery. RPP will be calculated as heart rate multiplied by systolic blood pressure (Omron MX3 Plus). Heart rate and systolic blood pressure will be measured under standardized resting conditions at each time point.
Local Muscle Oxygen Saturation (SmO₂)
时间窗: Time Frame: 3 times (Baseline, immediately after intervantion and 30 minutes after intervention) for each condition (CC, RT, RT+ST)
Local muscle oxygen saturation (SmO₂) will be assessed using near-infrared spectroscopy (Moxy Monitor). The sensor will be positioned over the target muscle region and secured to minimize movement artifacts. SmO₂ will be recorded as a local index of the balance between oxygen delivery and oxygen utilization within the sampled muscle region.
次要结局
- Brachial Artery diameter(Time Frame: 3 times (Baseline, immediately after intervention, and 30 minutes after intervention) for each condition (CC, RT, RT+SS))

- Pain pressure Threshold(PPT)(Time Frame: 3 times (Baseline, immediately after intervention, and 30 minutes after intervention) for each condition (CC, RT, RT+SS))
