CK: creatine kinase; HRex: exercise heart rate; HRR: heart rate recovery; RPE: rating of perceived exertion.

Time course of the training volume distribution over the 12-week study period in player J.
Table 1.
Two exemplary weekly training plans for player J.
Fig 3.
Players run 12.8 m shuttles for approximately 1, 1, and 3 min at 8.2 km/h, 9.6 km/h, and 11.0 km/h, respectively, followed by 1 min of standing recovery. HRex: average heart rate during the last 30 s of exercise; HRR: heart rate recovery during the 1-min recovery period; RPE: rating of perceived exertion (6–20 scale) at exercise cessation.
Fig 4.
Distributions of individual effect sizes between recovered and strained state for the different monitoring markers.
Plot displays individual standardized mean differences (d) between recovered and strained state. lnCK: natural logarithm of creatine kinase; lnUrea: natural logarithm of Urea; PPC: Physical Performance Capability (Short Recovery and Stress Scale, SRSS); OR: Overall Recovery (SRSS); MS: Muscular Stress (SRSS); OS: Overall Stress (SRSS); CMJ: countermovement jump height; EC: jump efficiency coefficient (multiple rebound jumps); HRex: exercise heart rate, RPE: rating of perceived exertion.

Summary of monitoring data.
Fig 5.
Individual exercise heart rate time series.
Plot displays individual HRex time series during the 12-week study period. Lines between data points are interrupted if measurements are not available or missing. Blue dots: ‘recovered’ state (Mondays), red dots: ‘strained’ state (Fridays).
Fig 6.
Change scores in exercise heart rate (HRex).
Plot displays separate distributions of individual change scores in response to training strain and recovery. A total of 26 ΔStrain and 36 ΔRecovery change scores were available.
Fig 7.
Short-term effect in exercise heart rate (HRex).
Plot displays mean difference between recovered and strained state with 90% confidence interval (black square with error bars), as well as interindividual response variability around the mean effect (i.e., ± interindividual SD, gray vertical line with caps). PMET: P value for minimum effect test against a minimum practically important difference of 1% [1].
