For 5 subjects, there was an error in the recording of
HRV parameters and hence were excluded from analysis.
ACWR and
HRV measures were modelled as categorical fixed effect predictor variables, whilst 'athlete ID' was included as a random effect.
Reliability of the
HRV thresholds method has been provided during maximal incremental cycling tests (18), but no study has been designed yet, to verify the
HRV thresholds' validity and reproducibility when determining L[T.
HRV parameters in depression and control group are shown in Table 2 (time domain) and Table 3 (frequency domain).
Among the methods available to assess the status of the autonomic nervous system,
HRV has emerged as a simple and noninvasive method to assess the sympathovagal activity at sinoatrial level (TASK FORCE OF THE EUROPEAN SOCIETY OF CARDIOLOGY AND THE NORTH AMERICAN SOCIETY OF PACING AND ELECTROPHYSIOLOGY, 1996).
Even if heart rate value increases, LF/HF ratio was largely unaffected by either acute myocar-dial ischemia, exercise Thus, the LFcomponent of
HRV does provide an index of cardiac sympathetic drive but also reflects a complex sympathetic, parasympathetic, and other unidentified factors accounting for the largest portion of the variability in this frequency range.
The tests were analyzed using the program Kubios
HRV 2.
In Section 3 and Section 4, calculated
HRV parameters and discussion are ensured respectively.
The prevalence of
HRV was significantly different ( F = 10.
HRV triangular index, which is the integral of the density distribution (i.
Premature heart beat was automatically ignored during
HRV spectral analysis.

HRV with no traumatic occlusion is a novel method to quantitatively assess heart autonomic nervous system function and diagnose CHD.
