Key result
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).
Why the study?
Does weekly heart rate variability monitoring detect nonfunctional overreaching in elite female wrestlers?
Population
34 elite female wrestlers (mean age 23 ± 3 years; height 165.6 ± 6 cm, weight 63 ± 8 kg)

Severe HRV perturbations may flag nonfunctional overreaching in wrestlers; hypothesis-generating and requires prospective validation before practice change.

Does weekly heart rate variability monitoring detect nonfunctional overreaching in elite female wrestlers?
p-value: p=<0.001
Severe perturbations in heart rate variability lasting >2 weeks can indicate an athlete's transition to nonfunctional overreaching, making it a useful tool for assessing training status.
Tian et al. (2012) conducted an 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).
