Abstract

Objective To validate the association between age and photoplethysmogram appearance, explore the impact of regular physical activity to pulse shape pattern and quantify the effect on trend of relative changes with advancing age. Methods This experiment involved 231 Chinese participants (aged 21-60 years, mean 40.10 ± 11.61 years), and their photoplethysmography signals were recorded from left index finger in rest state. The categorical analysis of IPAQ was performed to classify the subjects into levels of regular physical activity. Results Significant correlation coefficients were observed positively for age and Aging Character Index, which supported the previously reported view of association between age and changes in pulse shape characteristics. Significant differences of Aging Character Index between levels of regular physical activity were observed and quantitatively analyzed in all age groups. Conclusion The impact of regular physical activity to aging effect can be quantitatively measured through biological marker derived from photoplethysmogram appearance for dose-response analysis.

有规律的体育活动对指尖光体积描记图外观年龄相关变化模式的影响

目的验证年龄与光容积脉搏图表现的相关性，探讨规律运动对脉搏形态的影响，量化脉搏形态随年龄增长的相对变化趋势。方法231名年龄21 ~ 60岁(平均40.10±11.61岁)的中国受试者在静息状态下用左手食指记录其光体积脉搏波信号。对IPAQ进行分类分析，将受试者按规律体力活动的水平进行分类。结果年龄与衰老特征指数呈显著正相关，支持了先前报道的年龄与脉搏形状特征变化相关的观点。观察并定量分析各年龄组正常体力活动水平之间的衰老特征指数的显著差异。结论定期运动对衰老效应的影响可通过光体积描记图上的生物标记物进行定量测量，并进行剂量效应分析。
