Strength training (ST) is a strategy to enhance quality of life through increased strength, muscle hypertrophy, and functional capacity. Training systems are associated with manipulation of volume and intensity, generating different stimuli, such as Rest-Pause (RP) and Sarcoplasmic Stimulating Training (SST). These systems induce greater mechanical and physiological stress, leading to increased strength and muscle hypertrophy. However, the metabolic and psycho-affective effects of advanced systems in experienced practitioners remain inconclusive. The purpose of the study is to analyze the acute effects of RP, SST, and Traditional (TMS) systems on metabolic and psycho-affective responses in adult men.
This experimental crossover study assessed 15 subjects (30.38 ± 2.06 years; 88.40 ± 6.50 kg; 1.74 ± 0.07 cm) experienced in ST, evaluated under TMS, RP, and SST during flat bench press and leg press 45° exercises. Body composition, muscular strength via 1-RM testing, lactate concentration (LAC), and psycho-affective measures (Rating of Perceived Exertion-RPE; Visual Analog Scale-VAS; Feeling Scale-FS) were determined. Statistical analysis was performed using the Minitab software, with ≤ 0.05, IC-95%).
The finals results showed SST exhibited a 38.10% lower LAC concentration post-training session compared to TMS, while RP showed 37.20% lower LAC concentration than TMS post-session. Average RPE values for RP and SST were higher (8.50 ± 1.10 and 8.60 ± 0.90, respectively) than TMS (6.00 ± 1.10). VAS displayed higher average values for RP and SST (8.00 ± 2.00 and 8.00 ± 1.00, respectively) compared to TMS (5.00 ± 1.00), with affective ratings indicating positive values for TMS and values between 0 and -5 for RP (40%) and SST (60%) post-training sessions, suggesting that RP and SST induced less affective response than TMS.
The results lead to the conclusion that manipulation of training volume and intensity led to higher RPE and pain (VAS). The data suggest that inappropriate prescription of these systems could lead to greater displeasure, leading us to hypothesize that a higher likelihood of discontinuation from strength training programs would occur, suggesting that greater repetition volumes (RP and SST) should be targeted at individuals with a higher training level.
力量训练（ST）是一种通过增强力量、肌肉肥大和功能能力来提高生活质量的策略。训练系统与训练量和强度的调整相关联，会产生不同的刺激，如休息-暂停训练法（RP）和肌浆刺激训练法（SST）。这些训练系统会引发更大的机械和生理压力，从而导致力量增加和肌肉肥大。然而，对于有经验的训练者而言，这些进阶训练系统的代谢和心理情感影响仍尚无定论。本研究的目的是分析RP、SST和传统训练法（TMS）对成年男性代谢和心理情感反应的急性影响。
本实验性交叉研究评估了15名有力量训练经验的受试者（年龄30.38±2.06岁；体重88.40±6.50千克；身高1.74±0.07厘米），并在平板卧推和45°腿举训练中分别采用TMS、RP和SST进行评估。测定了身体成分、通过1-RM测试得出的肌肉力量、乳酸浓度（LAC）以及心理情感指标（主观用力程度分级-RPE；视觉模拟评分-VAS；情感量表-FS）。使用Minitab软件进行统计分析，显著性水平设定为≤0.05，置信区间为95%。
最终结果显示，与TMS相比，SST训练后LAC浓度降低了38.10%，而RP训练后LAC浓度比TMS降低了37.20%。RP和SST的平均RPE值（分别为8.50±1.10和8.60±0.90）高于TMS（6.00±1.10）。与TMS（5.00±1.00）相比，RP和SST的VAS平均值更高（分别为8.00±2.00和8.00±1.00），情感评分显示TMS为正值，而RP（40%）和SST（60%）训练后的情感评分为0至-5之间的值，这表明RP和SST引起的情感反应比TMS少。
结果得出结论，训练量和强度的调整会导致更高的RPE和疼痛感（VAS）。数据表明，这些训练系统的不当处方可能会导致更大的不适感，这使我们推测力量训练计划中断的可能性会更高，这意味着更大的重复训练量（RP和SST）应针对训练水平较高的个体。
