Infrared thermography is a noninvasive tool to monitor muscle damage, though its effectiveness is debated, as some studies report no skin temperature changes 24-48 h post-damage. These findings are often attributed to skin blood flow, but there is a lack of studies assessing this outcome. This study aimed to assess baseline skin temperature and skin blood flow responses 24 h after an induced quadriceps damage protocol and to establish a possible relationship between both variables. The thigh skin temperature and skin blood flow, pain perception, serum creatine kinase, and height of countermovement jump were measured in 15 physically active adults over 4 days, on two consecutive days per week. The induced muscle damage protocol, based on 100 drop jumps, was performed on the third day. Higher serum creatine kinase and pain perception (p < 0.01, ES > 1.20) were found 24 h after muscle damage induction. Thigh skin temperature and skin blood flow were unaffected by the muscle damage protocol, and a moderate correlation was observed between both outcomes (r = 0.59). We conclude that muscle damage does not alter skin blood flow 24 h after the induction, and therefore, this also had no consequences on skin temperature.
红外热成像技术是一种用于监测肌肉损伤的非侵入性工具，不过其有效性存在争议，因为一些研究报告称损伤后24至48小时皮肤温度没有变化。这些发现通常归因于皮肤血流，但缺乏评估这一结果的研究。本研究旨在评估在诱导股四头肌损伤方案实施24小时后的基线皮肤温度和皮肤血流反应，并确定这两个变量之间可能存在的关系。在15名身体活跃的成年人中，连续4天每周两天测量大腿皮肤温度、皮肤血流、疼痛感知、血清肌酸激酶以及反向运动跳跃高度。基于100次下落跳的诱导肌肉损伤方案在第三天进行。在肌肉损伤诱导后24小时发现血清肌酸激酶和疼痛感知升高（p<0.01，效应量>1.20）。大腿皮肤温度和皮肤血流不受肌肉损伤方案的影响，并且在这两个结果之间观察到中度相关性（r = 0.59）。我们得出结论，在诱导后24小时肌肉损伤不会改变皮肤血流，因此，这对皮肤温度也没有影响。
