Training Prescription Guided by Heart-Rate Variability in Cycling

Alejandro Javaloyes, Jose Manuel Sarabia, Robert Patrick Lamberts, and Manuel Moya-Ramon

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

Vagally Derived Heart Rate Variability and Training Perturbations With Menses in Female Collegiate Rowers

Sara R. Sherman, Clifton J. Holmes, Alexander P. Demos, Tori Stone, Bjoern Hornikel, Hayley V. MacDonald, Michael V. Fedewa, and Michael R. Esco

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

Comparison of Heart-Rate-Variability Recording With Smartphone Photoplethysmography, Polar H7 Chest Strap, and Electrocardiography

Daniel J. Plews, Ben Scott, Marco Altini, Matt Wood, Andrew E. Kilding, and Paul B. Laursen

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
