Monitoring of a female elite athlete over 38 weeks of functional-fitness training showed a mean ACWR of 1.1 ± 0.5 with 50% of weeks outside the safe zone, yet no injuries were reported.

Monitoring training load, well-being, and HRV is practical for managing functional-fitness training in elite athletes, showing that training can vary according to competition preparation without causing injury despite periods outside the ACWR safe zone.
The aim of this case study was to quantify the magnitude of internal load, acute/chronic workload ratio (ACWR), well-being perception, and heart rate variability (HRV) following 38 weeks of functional-fitness training in a female elite athlete. The internal load was obtained with session rating perceived exertion (session-RPE) while the ACWR was calculated by dividing the acute workload by the chronic workload (four-week average). Furthermore, HRV measurements were analyzed via a commercially available smartphone (HRV4training) each morning upon waking whilst in a supine position. The magnitude of internal load was: the weekly mean total during the 38 weeks was 2092 ± 861 arbitrary units (AU); during the preparation for the Open 2018 was 1973 ± 711 AU; during the Open 2018 it was 1686 ± 412 AU; and during the preparation for the Regionals was 3174 ± 595 AU. The mean ACWR was 1.1 ± 0.5 and 50% of the weeks were outside of the 'safe zone'. The well-being during the 38 weeks of training was 19.4 ± 2.3 points. There were no correlations between training load variables (weekly training load, monotony, ACWR, and HRV), and recuperation subjective variables (well-being, fatigue, sleep, pain, stress, and mood). This case study showed that the training load can be varied in accordance with preparation for a specific competition and ACWR revealed that 50% of the training weeks were outside of the 'safe zone', however, no injuries were reported by the athlete. The effectiveness and cost of these methods are very practical during real world functional-fitness.
Tibana et al. (Sat,) conducted a case report in Functional-fitness training (n=1). Functional-fitness training monitoring (internal load, ACWR, well-being, HRV) was evaluated on Magnitude of internal load, acute/chronic workload ratio (ACWR), well-being perception, and heart rate variability (HRV). Monitoring of a female elite athlete over 38 weeks of functional-fitness training showed a mean ACWR of 1.1 ± 0.5 with 50% of weeks outside the safe zone, yet no injuries were reported.
