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

psychological stress and represents a physiological hallmark of training fatigue. 6 , 7 A noninvasive measure of autonomic function is heart rate variability (HRV), which is quantified in the time domain from successive beat-to-beat fluctuations. HRV increases as a result of vagal (ie

negatively impact sleep. 5 For example, high-intensity evening exercise elicits sympathetic-mediated physiological responses, including an increase in nocturnal heart rate 3 , 4 and a reduction in heart rate variability (HRV). 3 Moreover, the stress of competition can manifest as negative mood states that

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

increasing or decreasing the heart rate resulting in shortened or lengthened R–R intervals. Heart rate variability (HRV) measures the variation in time between 2 consecutive heartbeats or R–R intervals of a cardiac cycle, 3 – 5 provides insight into the connection between the autonomic and cardiac systems

, autonomic nervous system). 1 – 3 Heart-rate variability (HRV) assessment has been widely used in football codes to evaluate cardiac vagal adaptation arising from short- 4 – 6 and long-term training 7 and gauge posttraining and postmatch recovery. 8 – 10 For example, in futsal (indoor 5-a-side football), a

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

applications includes physiological feedback mechanisms (i.e., biofeedback, neurofeedback). Heart rate variability (HRV) is a biofeedback measurement that has received increasing attention, largely due to improvements in availability and portability of technology ( Bar-Eli, 2002 ; Beauchamp, Harvey
