ABSTRACT
Objectives The aim of this study was to investigate the sleeping patterns of highly-trained adolescent swimmers. Further objectives were to compare subjective and objective measures of sleep and to evaluate the relationship between electronic device use and sleep in this cohort. Methods Fifteen national-level swimmers (age 16.4 ± 1.0 years) wore wrist actigraphs while completing sleep diaries over a two-week training period. Types of nights were classified as early morning training (≤7am - EARLY), day training (>7am - DAY), and no training (REST). Information on electronic device use before bed and other sleep behaviors was collected via questionnaires. Results Total sleep time (TST) was significantly ( p < 0.05) shorter on nights preceding EARLY (553 ± 106 hourmin) compared with nights preceding DAY (740 ± 112 hourmin) and REST (759 ± 119 hourmin). Participants overestimated subjective TST by â¼54 minutes when compared with objectively measured TST ( p < 0.05). Discussion Adolescent athletes obtained a greater amount of sleep prior to later training the next day or before rest days, when compared with early morning swim training the next day. Adolescents also overestimated their sleep duration by â¼1 hour per night. There were no significant relationships between electronic device use at night and measured sleep indices.
