The effects on maximal isometric trunk muscle strength and endurance after wearing a soft heat-retaining lumbar belt or a weightlifter's belt were studied. The soft belt (SB) study group comprised 12 construction workers with healthy backs, and the weightlifter's belt (WB) group comprised 24 construction workers with current or previous low back pain. The strength and endurance measurements were performed before the start of belt use, and after 1 and 2 months. The SB group increased the trunk flexor strength by 13% (p less than or equal to 0.01) after 2 months. The WB group increased the trunk flexor strength and endurance by 12% and 29%, respectively (p less than or equal to 0.001). No significant decrease of trunk muscle strength and endurance was found at the end of the follow-up period.
研究了佩戴柔软保暖型腰带或举重腰带后对最大等长躯干肌肉力量和耐力的影响。柔软腰带（SB）研究组由12名背部健康的建筑工人组成，举重腰带（WB）组由24名目前或既往有腰痛的建筑工人组成。在开始使用腰带前、使用1个月和2个月后进行力量和耐力测量。2个月后，SB组的躯干屈肌力量增加了13%（p≤0.01）。WB组的躯干屈肌力量和耐力分别增加了12%和29%（p≤0.001）。在随访期结束时未发现躯干肌肉力量和耐力有显著下降。
