- 对热的生理反应,如静止心率 (RHR) 变化,以及老年人的适应行为尚未得到充分理解.
- 可穿戴技术可以客观地监测对热的生理反应.
研究的目的:
- 在老年人中量化夏季温度和RHR之间的关联.
- 研究个人热适应行为如何改变温度-RHR关系.
- 在适应热量时考虑个体特征 (年龄,性别,BMI,慢性疾病).
主要方法:
- 2021年夏季在台北市对83名老年人 (≥65岁) 进行小组研究.
- 使用Garmin智能手表连续监测心率;RHR定义为最低30分钟平均值.
- 结构化的采访评估了热适应行为;收集了环境温度和湿度数据.

01:30Factors Influencing Heart Rate
6.1K
The heart rate, or pulse rate, is a vital indicator of cardiovascular health. It reflects the number of times the heart beats per minute. Various physiological and environmental factors influence heart rate, increasing or decreasing cardiac output. Understanding these factors is crucial for assessing heart function and identifying potential health issues.
Let us explore the significant factors affecting heart rate, including age, body temperature, posture, acute pain, chemical influences,...
