The present study aimed to assess the effects of asymmetric muscle fatigue on the skin surface temperature of abdominal and back muscles. The study was based on a pre-post/follow-up design with one group and included a total of 41 subjects (22 male, 19 female; age, 22.63 ± 3.91; weight, 71.89 ± 12.97 kg; height, 173.36 ± 9.95). All the participants were asked to perform side bends in sets of 20 repetitions on a Roman chair until complete exhaustion. The pre-, post- and follow-up test (24 h after) skin surface temperatures were recorded with infrared thermography. Subjective muscle soreness and muscle fatigue were analyzed using two questionnaires. The results of the post hoc tests showed that skin temperature was statistically significantly lower in the post-tests than in the pre- and follow-up tests, but no meaningful differences existed between the pre- and follow-up tests. Asymmetric side differences were found in the post-test for the upper and lower areas of the back. Differences were also noted for the front in both the upper and lower areas. No thermographic side asymmetries were found at the pre- or follow-up measurement for either the back or the front. Our results support the potential of using thermographic skin surface temperature to monitor exercise and recovery in athletes, as well as its use in rehabilitational exercise selection.
本研究旨在评估不对称肌肉疲劳对腹部和背部肌肉皮肤表面温度的影响。该研究基于一组前后/随访设计，共纳入41名受试者（男性22名，女性19名；年龄22.63±3.91岁；体重71.89±12.97千克；身高173.36±9.95厘米）。所有参与者被要求在罗马椅上进行侧弯，每组20次重复，直至完全疲劳。使用红外热成像记录测试前、测试后和随访（24小时后）的皮肤表面温度。使用两份问卷分析主观肌肉酸痛和肌肉疲劳情况。事后检验结果显示，测试后的皮肤温度在统计学上显著低于测试前和随访时的温度，但测试前和随访时的温度之间没有显著差异。在测试后发现背部上下区域存在不对称的侧别差异。在前后部的上下区域也发现了差异。在背部或前部的测试前或随访测量中均未发现热成像侧别不对称。我们的结果支持使用热成像皮肤表面温度来监测运动员的运动和恢复情况，以及其在康复运动选择中的应用潜力。
