To determine normal temperatures over the Patella tendon over eleven weeks.
A prospective cohort study with eleven weeks of observation.
University's Human Biomechanics and Physiology Laboratory.
Male or female collegiate runners running at least 25 miles per week who did not report pain in the region of the Patella tendon over 11 weeks of data collection.
Thermal images taken at the same time and day of the week, were used to measure the temperature of the skin over the Patella tendon.
Eighteen athletes were eligible for analysis. The mean temperature of the Patella tendon was 30.13 °C (SD = 1.51 °C). Patella tendon temperature changes over time were insignificant (right p = 0.66, left p = 0.90) with ICC right = 0.92, left = 0.94. Mean temperature difference side to side was 0.14 °C (SD = 0.60 °C). Mixed-model Linear regression for mean temperature differences found the effect of (i) time (t = 0.39, p = 0.70, df = 361) and (ii) side (t = -0.89, p = 0.38, df = 361) to be insignificant.
This is the first report of normal thermal profiles of collegiate runners over an extended period. Temperature variation above 1.20 °C may represent an abnormal asymmetry in the running population. Variations in Patella tendon temperatures left to right, and over time were not significant.
确定髌腱在十一周内的正常温度。
一项为期十一周观察的前瞻性队列研究。
大学人体生物力学与生理学实验室。
每周至少跑25英里的男女大学生跑步者，在为期11周的数据收集期间，他们在髌腱区域未报告疼痛。
在一周中的同一天同一时间拍摄的热成像，用于测量髌腱上方皮肤的温度。
18名运动员符合分析条件。髌腱的平均温度为30.13°C（标准差=1.51°C）。髌腱温度随时间的变化不显著（右侧p=0.66，左侧p=0.90），组内相关系数右侧为0.92，左侧为0.94。左右平均温度差为0.14°C（标准差=0.60°C）。平均温度差的混合模型线性回归发现，（i）时间（t=0.39，p=0.70，自由度=361）和（ii）侧别（t=-0.89，p=0.38，自由度=361）的影响不显著。
这是关于大学生跑步者长期正常热分布图的首次报告。超过1.20°C的温度变化可能代表跑步人群中的异常不对称。髌腱温度左右之间以及随时间的变化不显著。
