cardiovascular health and prognosis ( Schwartz, La Rovere, & Vanoli, 1992 ). Heart rate variability (HRV), measured by the variation in the beat-to-beat intervals, is a noninvasive tool for the evaluation of cardiac autonomic function and is shown to be negatively influenced by menopause ( Brockbank, Chatterjee

response highlights the importance of monitoring properly, because without the RPE data, functional overreaching might be interpreted as an improvement in training status. In addition to HRR, heart-rate variability (HRV), which focuses on the variability of successive R–R intervals, 13 also gained

Heart rate variability (HRV) has evolved as a noninvasive physiological marker which sport scientists and coaches can utilize to assess and optimize training adaptations and performance in their athletes. 1 – 6 HRV reflects global cardiac-autonomic modulation at the individual level, and proper

striving for peak performances, the need to effectively monitor human movement and physiological state are important so that more objective decisions around training can be made. 2 The regular assessment of heart rate variability (HRV) has immerged as a measure of “physiological state” that has grown in

the relationship between PA and autonomic function did not include the measurement of insulin. The aim of this study in the general population was to clarify whether the association between PA and the parameters of heart rate variability (HRV), as an index of autonomic function, was influenced by

Heart rate variability (HRV), a noninvasive method to estimate the vagal fluctuations of the heart, 1 – 3 has been used to study the effects of different exercise training protocols on cardiac autonomic modulation. 4 – 8 An exercise session represents a stimulus that causes a disturbance of the
