All the participants (30 soccer players aged U17) will perform all the procedures of (1) sleep quality/quantity assessment, (2) postactivation potentiation, (3) running protocol, (4) cold-water immers

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Cryotherapy intervention (cold-water immersion) will impair subsequent kicking performance (decrease ball velocity and increase accuracy) measured using 3-D kinematics, when quantitative chance (? 75%) of the true difference being lower than 0,2 multiplied by between-subject standard deviation in the intervention compared to control condition | — |
Secondary
| Measure | Time frame |
|---|---|
| Voltage amplitude and mean spectral power to a given frequency band, conectivity and synchronization/desynchronization percentage, using EEG ;Measures of quality and quantity of sleep: bed time, total sleep time, wake time, total bed time, sleep latency, sleep eficiency (total sleep time in percentage of bedtime), wake up after bedtime and day naps, using wrist actigraphy;Root mean square, median frequency and activation percentage of the Vastus lateralis, rectus femoris and biceps femoris muscles using EMG | — |
