Sleep quantity and quality in elite youth soccer players: A pilot study

摘要: This study examined the effect of early evening high-intensity training on sleep elite male youth soccer players (n = 12) using wrist actigraphy. High-intensity (TRAIN) nights were compared with a home environment (HOME) condition, created by averaging variables night before and after TRAIN nights. Additionally, athletes alternately used cold water immersion (TRAIN+CWI) or none, to assess whether (CWI) had any impact quality quantity. Ratings perceived exertion, fatigue recovery recorded training. Actigraphy measures bedtime, wake time, duration, onset latency, efficiency onset. Self-rated scores sleepiness at bedtime wake, plus overall also recorded. Only ratings higher in TRAIN+CWI there no other differences data. Both conditions significant later (07:45 ± 1:09 h p < 0.01 07:34 1:20 0.01) times than HOME (06:44 0:41 h). The condition significantly (7 2; rating (6 1), but further found (actigraphy self-reported) measures. Across all conditions, time spent asleep was ∼7:30 (±0:52) h:min ∼89% (±6.1). In conclusion, subsequent quantity, nor performing CWI post-training.
