TL;DR: To provide a full picture of the training demands, ETL was commonly complemented by internal training load monitoring with the rating of perceived exertion predominantly adopted instead of heart rate recordings.

TL;DR: Changes in ultra-short HRV measures during futsal preseason were associated with increased performance, and players who accumulated higher perceived TLs displayed smaller improvements in the Yo-Yo IR1 performance and HRV.

TL;DR: The substantial individual variability in sleep and HRV measures is highlighted, suggesting the adoption of an individual approach to monitor sleep, training and match loads and recovery, to better understand how players cope with highly demanding competitions.

TL;DR: Overall, the time of day for soccer practice and match location may cause disruption in sleep patterns and/or in autonomic cardiac activity in female soccer players and playing official matches during the day and training at night may affect nocturnal cardiac autonomic activity by decreasing vagal-related modulation and increasing HR during sleep.

TL;DR: Overall, the results indicate that exercise training conducted at night may disturb sleep and affect HR, whereas limited effects can be expected in HR variability assessed during sleep in high-level female soccer players.
