Heart rate variability (HRV) can provide physiological information about the autonomic nervous system. For the HRV spectral analysis, spectral windows are applied as weighting functions to solve the spectral leakage problem. The present study aimed t

Heart rate variability (HRV) expressing variations in the heart period (NN interval) has been widely analyzed to quantify autonomic regulation. However, mathematically biased HRV results are obtained for different average heart rates (HRs) due to the

Bone adapts to its environment. Osteoblasts and osteocytes are subject to mechanical load in vivo. It has been shown that osteoblasts alter cytokine expression in response to mechanical loading. However, signal transduction pathways that mediate bone
