Key result
Two-month stationary bike training linked to improved HRV, though mental stress blunts the benefit.
Why the study?
Monitoring and optimizing recovery is essential to avoid overtraining, and HRV reflects autonomic nervous system function and responses to exercise stressors.
Does HRV monitoring reflect physical and mental stress levels to guide stationary bike training performance in healthy college students?
Observational (n=10)

Does HRV monitoring reflect physical and mental stress levels to guide stationary bike training performance in healthy college students?
Monitoring HRV during stationary bike training provides insights into physical and mental stress, potentially aiding in the optimization of exercise performance and recovery.
HRV gains from stationary bike training attenuated by mental stress; hypothesis-generating for monitoring-guided programs, prospective trials needed.
Exercising is said to bring benefits to people taking part in, not only physical but also physiological gain. Heart Rate Variability (HRV) is an important marker reflecting the function of the autonomic nervous system (ANS), which has shown potentials in some exercise therapy and sport physiology studies. HRV analysis is said to be used for getting a better understanding of our body’s response to exercise and the reaction to different stressors from the workout. Thus, it is essential to monitor and optimize the recovery to avoid overtraining. This study aims to investigate the influence of HRV reflecting the physical stress level on participants when exercising, therefore, building a concept of self-training guide to improve the adaptation and performance. Electrocardiogram (ECG) is acquired by the BIOPAC system over 10 healthy college students during a proposed training protocol on the stationary bike, and post-exercising. HRV data from ECG is analyzed in time, frequency and nonlinear domains to extract various features to evaluate physiological recovery status, manage physical fatigue, intensity adjustment. From the evaluation of these indexes, participants are able to keep track of their physiological condition as well as to have more effective training exercises.

Pham et al. (2020) conducted an observational in Healthy (n=10). Stationary bike training vs. Baseline was evaluated on Heart Rate Variability (HRV) parameters including LF/HF ratio and time domain indices. A 2-month stationary bike training program generally improved heart rate variability and autonomic nervous system balance in healthy male college students, though mental stress reduced training efficacy.
