Severe perturbations in heart rate variability lasting >2 weeks, either above or below normal responses, indicated an athlete's transition to nonfunctional overreaching (p<0.001).
Observational (n=34)
valor p: p=<0.001
Functional overreaching (FOR) represents intense training followed by a brief reduction in performance and then a rapid recovery (2 weeks indicated an athlete's transition to NFOR and, hence, are useful for assessing possible overreaching/training.
Tian et al. (Mon,) conducted a observational in Nonfunctional overreaching (n=34). Heart rate variability (HRV) monitoring was evaluated on Heart rate variability thresholds (rMSSD and SDNN) for FOR/NFOR (p=<0.001). Severe perturbations in heart rate variability lasting >2 weeks, either above or below normal responses, indicated an athlete's transition to nonfunctional overreaching (p<0.001).
