HRV Insights

High heart rate variability (HRV) isn't always a positive indicator; it can signal different physiological responses depending on the context. For example, while an increase in sympathetic tone is expected after a training break, overtraining in athletes can lead to a concerning rise in parasympathetic tone. Monitoring long-term HRV trends is crucial, as acute spikes may indicate the body’s struggle to adapt to stress, suggesting the need for adjustments in training and recovery strategies.
