Applied Wearable Devices For Digital Health Based On Novel Cardiac Force Index Of Running Performance:Cross-sectional Study
ABSTRACT
Background:
Marathons and road running have become popular in recent years, sudden cardiac death may occur even in young populations.
Objective:
Early detection the cardiac function changes during running is imperative.
Methods:
We investigated the correlations among the 2 new physiological parameters, including cardiac force index (CFI) = weight * activity / heart rate, cardiac force ratio (CFR) = CFI of running / CFI of walking, and finish times for 3000 meters of running.This study used the American Zephyr™ product BioHarness 3.0. It can measure basic physiological parameters, including heart-rate, respiratory rate, temperature, maximum oxygen consumption and activity.
Results:
After analysis of multi-variates logistic regression model, accumulation of heart activities during running was statistically significant with the qualification of the 3000-meter running test (p = 0.04). Finally, we compared the correlations of CFR(s) between runners with stronger and weaker cardiac force during 3000-meter running
Conclusions:
In conclusion, this study results suggested that real-time CFR changes could be a predication model for the 3000-meter running performance.
