Descrição detalhada
This randomized controlled crossover study was conducted in young elite male soccer players from a professional soccer club academy to investigate the effects of nocturnal compression garments on sleep quantity and quality.
The study was conducted over four consecutive weeks. During the first week, all participants completed a baseline control condition without wearing any garment during the night. This baseline condition was always performed first and was not randomized. During the following three weeks, participants completed three garment conditions in a randomized order: full-length compression leggings, compression calf sleeves, and non-compressive placebo garments. Each condition was maintained for seven consecutive nights.
Participants were instructed to put on the assigned garment approximately two hours before bedtime, wear it throughout the night, and remove it after waking. The placebo garment was designed to provide a similar wearing experience without applying meaningful compression.
Sleep was assessed objectively using wrist actigraphy and subjectively using self-reported sleep measures. Objective sleep variables included total sleep time, time in bed, sleep latency, sleep efficiency, and the number of nocturnal awakenings.
To limit potential confounding factors, external and internal training loads, perceived stress, fatigue and muscle soreness, pre-sleep nutritional intake, and nocturnal thermal conditions were monitored throughout the experimental period. The study was conducted under standardized living and training conditions within the professional soccer academy environment.

Mean Sleep Efficiency Assessed by Wrist Actigraphy
Prazo: Measured nightly and averaged across the 7 consecutive nights of each condition
|
Sleep efficiency was assessed by wrist actigraphy and calculated as the percentage of time in bed spent asleep.
Nightly sleep efficiency values were averaged across the seven consecutive nights of each experimental condition.
Higher values indicate greater sleep efficiency.

Subjective Sleep Quality Assessed Using the Sleep Item of the Hooper Questionnaire
Prazo: Assessed nightly during each 7-night condition
|
Subjective sleep quality was assessed using the sleep-quality item of the Hooper Questionnaire (Hooper et al., 1995).
Participants rated the quality of the previous night's sleep on a 7-point Likert-type scale ranging from 1 (very, very good) to 7 (very, very bad), with higher scores indicating poorer perceived sleep quality.
