This study aimed to investigate the acute effects of different pre-ST strategies on muscular performance and blood pressure (BP) responses in recreationally strength-trained women.
Twelve overweight women with normal BP were recruited and performed six experimental protocols in a randomized order: (1) control protocol (CC), where BP was assessed without exercises performed; (2) ST; (3) foam rolling warm-up followed by ST (FR + ST); (4) specific warm-up followed by ST (SW + ST); (5) aerobic exercise followed by ST (AE + ST); and (6) stretching exercises followed by ST (SE + ST). ST consisted of three sets at 80% of 10 repetition maximum with a self-suggested rest interval between sets for bench press, back squat, bench press 45°, front squat, lat pull-down, leg press, shoulder press, and leg extension.
All experimental protocol had a lower total training volume, fatigue index, and repetitions performance in relation to ST ( < 0.05). No significant reduction was observed in systolic and diastolic BP for any protocol or exercise, although the effect size magnitudes ranged from trivial to large. Decreases in maximum repetitions, resistance to fatigue, and total training volume were performed before ST as warm-up strategies. However, these strategies indicated a clinical reduction in BP with a large and meaningful magnitude (effect size) in recreationally strength-trained women with normal to elevated BP.
The results of this investigation may help to influence decision-making by practitioners who desire to elicit a post-exercise hypotension response in both subjects with normal BP and hypertension.
本研究旨在调查不同的预抗阻训练（pre-ST）策略对进行休闲力量训练的女性肌肉性能和血压（BP）反应的急性影响。
招募了12名血压正常的超重女性，并按随机顺序进行了六种实验方案：（1）对照方案（CC），即不进行运动时评估血压；（2）抗阻训练（ST）；（3）泡沫轴热身然后进行抗阻训练（FR + ST）；（4）专项热身然后进行抗阻训练（SW + ST）；（5）有氧运动然后进行抗阻训练（AE + ST）；以及（6）伸展运动然后进行抗阻训练（SE + ST）。抗阻训练包括以10次重复最大值的80%进行三组练习，每组之间有自我建议的休息间隔，练习动作包括卧推、后深蹲、45°卧推、前深蹲、下拉、腿举、肩推和腿伸展。
与抗阻训练相比，所有实验方案的总训练量、疲劳指数和重复表现均较低（P < 0.05）。尽管效应大小范围从小到大都有，但未观察到任何方案或运动的收缩压和舒张压有显著降低。在进行抗阻训练前，作为热身策略进行了最大重复次数、抗疲劳能力和总训练量的降低。然而，这些策略表明，在血压正常至升高的进行休闲力量训练的女性中，血压有临床上较大且有意义的降低幅度（效应大小）。
本调查结果可能有助于影响那些希望在血压正常和高血压受试者中引发运动后低血压反应的从业者的决策。
