The elderly are particularly vulnerable to degenerative diseases, such as circulatory and respiratory system and vascular system diseases. The objective of this study was therefore to evaluate the distribution of temperature and the dynamics of venous blood flow in the lower limbs (LLs) and to assess the interdependence of these parameters in terms of the somatic components in males and females participating in activities at the University of the Third Age.
The study included 60 females (mean age 67.4 years) and 40 males (mean age 67.5 years). A body composition assessment was performed using the bioimpedance technique - Tanita BC-418MA. The following parameters were examined: fat%, fat mass, fat-free mass, and total body water. The minimal, maximal, and mean temperature values and their distributions were examined using infrared thermographic camera VarioCAM Head. Measurements of the venous refilling time and the work of the LL venous pump were examined using a Rheo Dopplex II PPG.
In males, the mean value of the right LL temperature was 30.58 and the mean value of the left LL was 30.28; the -value was 0.805769. In females, the mean value of the right LL temperature was 29.58 and the mean value of the left limb was 29.52; the -value was 0.864773. In males, the right limb blood flow was 34.17 and the left limb blood flow was 34.67; the -value was 0.359137. In females, the right limb blood flow was 26.89 and the left limb blood flow was 26.09; the -value was 0.796348.
Research results showed that the temperature distribution and the dynamics of blood flow are not significantly different between the right and left extremities in both males and females. However, significant temperature differences were found between the gender groups. Significantly higher temperature values in both the right and left extremities were recorded in males than in females.
老年人特别容易患退行性疾病，如循环系统、呼吸系统和血管系统疾病。因此，本研究的目的是评估下肢温度分布及静脉血流动力学，并根据参与第三年龄大学活动的男性和女性的身体组成部分评估这些参数之间的相互依存关系。
该研究纳入了60名女性（平均年龄67.4岁）和40名男性（平均年龄67.5岁）。使用生物电阻抗技术（Tanita BC - 418MA）进行身体成分评估。检测了以下参数：脂肪百分比、脂肪量、去脂体重和总体水。使用红外热成像相机VarioCAM Head检测最低、最高和平均温度值及其分布。使用Rheo Dopplex II PPG检测静脉再充盈时间和下肢静脉泵的工作情况。
在男性中，右下肢温度平均值为30.58，左下肢温度平均值为30.28；P值为0.805769。在女性中，右下肢温度平均值为29.58，左下肢温度平均值为29.52；P值为0.864773。在男性中，右下肢血流量为34.17，左下肢血流量为34.67；P值为0.359137。在女性中，右下肢血流量为26.89，左下肢血流量为26.09；P值为0.796348。
研究结果表明，男性和女性左右肢体的温度分布和血流动力学无显著差异。然而，在不同性别组之间发现了显著的温度差异。男性左右肢体的温度值均显著高于女性。
