Abstract：
UNASSIGNED: Infrared thermography is gaining attention in the field of sports medicine and performance. This study investigated the effects of static and dynamic warm-ups and a 90° change of direction (COD) exercise on the thermal response of the knee.
UNASSIGNED: Thermograms were collected using the FlIR E54 Imaging Camera from 85 healthy young adults, 46 men and 39 women, aged 20-31 years. The participants were divided in two groups, static and dynamic warm-up. Four thermograms were taken: baseline (T0), warm-up (T1), COD (T2), and rest (T3). Four regions of interest (ROIs) of the knee were analyzed: anterior upper half (AUH), anterior lower half (ALH), posterior upper half (PUH), and posterior lower half (PLH). Mixed ANOVA with the Bonferroni-Holm test and independent t-test were used for pairwise comparison and to spot differences between the right and left knees at T1 and T2 and at T0 between men and women, respectively.
UNASSIGNED: The mixed ANOVA was significant for time points (p< 0.001) in all the ROIs and for the stretching/temperature interaction with different levels of significance. The t-test results for the right and left knees at T1 and T2 were not significant. The temperature in the static warm-up group followed a decrease at T1, a subsequent decrease at T2, and a recovery similar to the baseline at T3, in the ALH in men and women and in the PUH only in men.
UNASSIGNED: Static stretching was more suitable for preparing the knee for the COD exercise than the dynamic one in terms of the thermal response.

摘要：
■红外热成像技术在运动医学和性能领域越来越受到重视。这项研究调查了静态和动态热身以及90°方向变化（COD）运动对膝盖热响应的影响。
■使用FlIRE54成像相机从85名健康的年轻人收集热谱图，46男39女,20-31岁。参与者被分成两组，静态和动态热身。采集了四个温谱图：基线(T0)，预热(T1)，COD(T2),休息（T3）分析了膝关节的四个感兴趣区域（ROI）：前上半部（AUH），前下半部（ALH），后上半部分(PUH),和后下半部（PLH）。混合方差分析与Bonferroni-Holm检验和独立t检验用于成对比较，并发现男女在T1和T2和T0时左右膝盖之间的差异，分别。
■混合ANOVA对于所有ROI中的时间点(p<0.001)和对于具有不同显著性水平的拉伸/温度相互作用是显著的。T1和T2时左右膝的t检验结果不显著。在男性和女性的ALH以及仅男性的PUH中，静态热身组的温度在T1时降低，随后在T2时降低，并且与T3时的基线相似。
■在热响应方面，静态拉伸比动态拉伸更适合为COD运动准备膝盖。
