Comparison of Six-week Velocity-Based Training versus Percentage-Based Training Programs on Lower-Body Strength and Sticking Region in Squat Exercises

This study compared the effects of Velocity-Based Training (VBT) and Percentage-Based Training (PBT) on lower-body strength and the sticking region in squat exercises among resistance-trained males over six weeks intervention. Twenty resistance-trained males were randomized to train under a 10% velocity loss threshold VBT group(n=10, Age = 21.96 ± 2.27, height = 1.79 ± 0.04 m, weight = 70.98 ± 6.16 kg) or traditional PBT group (n=10, Age = 22.12 ± 2.38, height = 1.78 ± 0.02 m, weight = 74.14 ± 4.87 kg), each training twice weekly for six weeks. The study measured changes in squat one-repetition maximum (1RM), relative strength, countermovement jump (CMJ), standing long jump (SLJ), duration of the sticking region, and average velocity in the sticking region using pre-test and post-test. Results indicated significant improvements in squat 1RM, relative strength, and CMJ for both groups, with no significant changes in sticking region velocity (p &gt; 0.05). Except for squat 1RM improvements (p &lt; 0.01), no other significant differences were noted between groups post-intervention (p &gt; 0.05). In conclusion, both interventions significantly enhanced lower-body strength, with the VBT regimen showing greater effectiveness. Neither approach significantly altered the duration or velocity of the sticking region, though the PBT regimen yielded more favorable improvements in sticking region performance. These findings suggest that differences in muscle adaptation and strength qualities between regimens might explain the varied impacts on the sticking region. Future research could explore these aspects to further refine training strategies for improving sticking region performance across various movement phases.<br><br>Data collection device: https://www.mdpi.com/1424-8220/23/5/2435This study is being submitted for publication, and more details will be updated after acceptance.<br>

本研究针对具备力量训练经验的男性群体，对比了基于速度的训练（Velocity-Based Training, VBT）与基于百分比的训练（Percentage-Based Training, PBT）对六周干预后受试者下肢力量及深蹲动作停滞区域的影响。本研究招募20名有力量训练经验的男性，将其随机分为两组，每组10人：以10%速度损失阈值为标准的VBT组（年龄21.96±2.27岁，身高1.79±0.04m，体重70.98±6.16kg）与传统PBT组（年龄22.12±2.38岁，身高1.78±0.02m，体重74.14±4.87kg），两组均每周训练2次，持续六周。

本研究通过前测与后测，采集两组受试者的多项指标变化，包括深蹲单次最大重量（one-repetition maximum, 1RM）、相对力量、反向跳（countermovement jump, CMJ）成绩、立定跳远（standing long jump, SLJ）成绩、停滞区域持续时长以及停滞区域平均速度。结果显示，两组受试者的深蹲1RM、相对力量及CMJ成绩均获得显著提升，但停滞区域速度无显著变化（p>0.05）。干预后，除深蹲1RM的提升幅度存在组间显著差异（p<0.01）外，其余指标组间均无显著差异（p>0.05）。

综上，两种训练方案均能显著提升受试者的下肢力量，其中VBT方案的提升效果更优。两类方案均未显著改变停滞区域的持续时长与速度，但PBT方案在停滞区域表现的改善上效果更理想。本研究结果提示，不同训练方案在肌肉适应性与力量素质层面的差异，或可解释其对深蹲停滞区域产生的差异化影响。未来可围绕该方向开展相关研究，进一步优化可改善不同动作阶段停滞区域表现的训练策略。

背景概述

该数据集比较了六周速度基础训练（VBT）和百分比基础训练（PBT）对下蹲运动中下半身力量和粘滞区的影响。研究结果表明，两种训练方法均能显著提高下半身力量，其中VBT在提高蹲举1RM方面更为有效，但粘滞区的表现未受显著影响。
