Current metrics like baseline heart rate (HR) and HR recovery fail in predicting overtraining (OT), a syndrome manifesting from a deteriorating autonomic nervous system (ANS). Preventing OT requires tracking the influence of internal physiological loads induced by exercise training programs on the ANS. Therefore, this study evaluated the predictability of a novel, exercise cardiac load metric on the deterioration of the ANS.

Article Synopsis
- The autonomic nervous system (ANS) is crucial for athletes' performance, and insufficient recovery during training can hurt their performance.
- A study tracked collegiate football players over 13 weeks, using armband monitors to assess their exercise cardiac load (ECL), heart rate (HR), and heart rate variability (HRV) to gauge ANS function and recovery.
- Findings revealed that higher ECLs negatively impacted running speed, while better HRV was linked to improved speed, suggesting that managing training intensity and recovery is essential for optimal performance during the season.
The autonomic nervous system (ANS) is profoundly affected by high intensity exercise. However, evidence is less clear on ANS recovery and function following prolonged bouts of high intensity exercise, especially in non-endurance athletes. Therefore, this study aimed to investigate the relationships between duration and intensity of acute exercise training sessions and ANS recovery and function in Division I football athletes.
