Therefore, various, sometimes complex measuring methods for this parameter are available in competitive sports. A new generation of wearables promises consumer-friendly applications, e. g. the Vital Monitor calculates a regeneration and stress index based on HRV values. The aim of the study was to check whether the Vital Monitor represents the effects of a 3-day intensive endurance training comparable to established methods for the determination of performance or the subjective rss. 10 male subjects (25.1 ± 3.3 years) completed after baseline measurement, a Peak Power Output-Test (410.0 ± 48.31 W, 184.2 ± 11.59 HRmax) followed by a 3-day regeneration phase, followed by a 3-day intensive training phase with 6 training sessions. Before each training session the submaximal endurance performance was measured using the Lambert and Lambert submaximal cycling test (LSCT). On all examination days, the rss was measured in the morning using the Acute Recovery Stress Scale (ARSS) and using the Vital Monitor. The rmAnova shows high significant differences for the LSCT and ARSS dimensions (p ≤ 0.004) with a large effect strength (η2 from 0.46 to 0.70), while the regeneration and stress values of the Vital Monitor as well as the HRV values show no significant differences for an average effect strength (η2 from 0.09 to 0.13). Both the LSCT and the ARSS clearly indicate fatigue during the intervention period, while the parameters of the Vital Monitor show no clear effect but only a tendency.» weiterlesen» einklappen
