To compare the effects of combinations of resistance training (RT) and static stretching (SS) on heart rate (HR), systolic pressure (SBP), diastolic pressure (DBP), rate pressure product (RPP), oxygen saturation (SpO2), rating of perceived effort (RPE), and heart rate variability (HRV) in men.
Twelve normotensive healthy men participated in four protocols: a) SS+RT, b) RT+SS, c) RT, and d) SS. Variables were measured before, immediately after, and 15, 30, and 45 min after the sessions.
The combination of SS and RT increased (p<0.001) HR when compared to the effects of the noncombined protocols (from 2.38 to 11.02%), and this result indicated metabolic compensation. Regarding DBP, there were differences (p<0.001) between the RT and SS groups (53.93±8.59 vs. 67.00±7.01 mmHg). SS has been shown to be able to reduce (p<0.001) SpO2 (4.67%) due to the occlusion caused by a reduction in the caliber of the blood vessels during SS compared to during rest. The increase in RPP (6.88% between RT and SS+RT) along with the HR results indicated higher metabolic stress than that reflected by the RPE (combined protocols increased RPE from 21.63 to 43.25%). The HRV analysis confirmed these results, showing increases (p<0.01) in the LF index between the combined and noncombined protocols. Compared to the effect of RT, the combination of SS and RT promoted a vagal suppression root mean square of the successive differences (RMSSD) index (from 9.51 to 21.52%) between the RT and SS+RT groups (p<0.01) and between the RT and RT+SS groups (p<0.001).
Static stretching increases cardiac overload and RPE, reducing oxygen supply, especially when performed in combination with RT.
比较抗阻训练（RT）和静态拉伸（SS）组合对男性的心率（HR）、收缩压（SBP）、舒张压（DBP）、心率血压乘积（RPP）、血氧饱和度（SpO2）、主观用力感觉等级（RPE）和心率变异性（HRV）的影响。
12 名血压正常的健康男性参与了 4 个方案：a）SS+RT，b）RT+SS，c）RT，和 d）SS。在运动前后以及运动后 15、30 和 45 分钟时测量变量。
与非组合方案相比，SS 和 RT 的组合增加了（p<0.001）HR（从 2.38 增加到 11.02%），这一结果表明存在代谢补偿。关于 DBP，RT 和 SS 组之间存在差异（p<0.001）（53.93±8.59 对 67.00±7.01mmHg）。由于 SS 时血管口径减小导致血管闭塞，SS 被证明能够降低（p<0.001）SpO2（4.67%）。与 RT 和 SS+RT 相比，RPP 的增加（6.88%）与 HR 结果一起表明代谢应激高于 RPE 所反映的应激（组合方案将 RPE 从 21.63 增加到 43.25%）。HRV 分析证实了这些结果，显示在组合与非组合方案之间 LF 指数增加（p<0.01）。与 RT 相比，SS 和 RT 的组合促进了迷走神经抑制的均方根差（RMSSD）指数（从 9.51 增加到 21.52%），在 RT 和 SS+RT 组之间（p<0.01）和 RT 和 RT+SS 组之间（p<0.001）。
静态拉伸会增加心脏负荷和 RPE，减少氧气供应，尤其是在与 RT 结合时。
