Research investigating lumbosacral corset designs and their effects are limited and conflicting. The objective was to compare thoraco-lumbo-sacral support corsets (polyester/nylon: TLSSC-poly and neoprene: TLSSC-neo) with a traditional model (TRAD) and Control. Twenty male, university-aged, healthy, recreationally active, participants performed Biering-Sorensen back endurance (BS) test and box lifting tasks (BL:30 repetitions using 20% body mass). Lower and upper erector spinae and hamstrings electromyography (EMG); trunk-hip, knee, and ankle kinematics as well as endurance time were monitored. With BL, the TLSSC-poly (121.4°±17.9) exhibited 1.9% (p = 0.01), 2.7% (p = 0.003), and 3.7% (p = 0.0003) greater knee flexion than TRAD (119.1°±17.5), TLSSC-neo (116.8°±17.4) and Control (120.1°±17.6) respectively. The TLSSC-poly (101.9°± 8.9) demonstrated significant 3.5% (p = 0.005), 2.2% (p = 0.002) and 1.4% (p = 0.01) greater dorsiflexion than TRAD (103.4°±8.7), TLSSC-neo (104.2°±9.8) and Control (105.7°±7.2) respectively. With BS, TLSSC-poly (137.4-s±31.2, 9.7%, p = 0.018) and TLSSC-neo (133.8-s±32.3, 9.2%, p = 0.006) exhibited significantly longer durations than Control (124.8-s±29.8). Relevance to industry: The TLSSC increased BS endurance and TLSSC-poly increased BL knee and ankle angles, possibly providing benefits for workers, with repeated actions over a full work day.

研究腰s紧身胸衣设计及其影响的研究是有限的并且相互矛盾。目的是将胸腰lum支持紧身胸衣（聚酯/尼龙：TLSSC-poly和氯丁橡胶：TLSSC-neo）与传统模型（TRAD）和对照进行比较。二十名男性，大学年龄，健康，娱乐活跃的参与者进行了Biering-Sorensen背耐力（BS）测试和举重任务（BL：30次重复，使用20％体重）。下部和上部竖脊肌和绳肌肌电图（EMG）；监测躯干，膝盖和脚踝的运动学以及耐力时间。与BLAD相比，TLSSC-poly（121.4°±17.9）膝关节屈曲度比TRAD（119.1°±17.5）高1.9％（p = 0.01），2.7％（p = 0.003）和3.7％（p = 0.0003）， TLSSC-neo（116.8°±17.4）和对照（120.1°±17.6）。TLSSC-poly（101.9°±8。9）的背屈比TRAD（103.4°±8.7），TLSSC-neo（104.2°±9.8）和对照（10％）分别高3.5％（p = 0.005），2.2％（p = 0.002）和1.4％（p = 0.01）。 105.7°±7.2）。使用BS时，TLSSC-poly（137.4-s±31.2，9.7％，p = 0.018）和TLSSC-neo（133.8-s±32.3，9.2％，p = 0.006）的持续时间明显长于对照（124.8-s±29.8） ）。与行业的相关性：TLSSC增加了BS的耐力，而TLSSC-poly增加了BL膝盖和脚踝的角度，这可能为工人带来了好处，并且需要在整个工作日中重复进行操作。006）的持续时间明显长于对照（124.8-s±29.8）。与行业的相关性：TLSSC增加了BS的耐力，而TLSSC-poly增加了BL膝盖和脚踝的角度，这可能为工人带来了好处，并且需要在整个工作日中重复进行操作。006）的持续时间明显长于对照（124.8-s±29.8）。与行业的相关性：TLSSC增加了BS的耐力，而TLSSC-poly增加了BL膝盖和脚踝的角度，这可能为工人带来了好处，并且需要在整个工作日中重复进行操作。
