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.<\/jats:p><jats:p>\n          Methods\u2003Fifteen national-level swimmers (age: 16.4\u2009\u00b1\u20091.0 years) wore wrist actigraphs while completing sleep diaries over a two-week training period. Types of nights were classified as early morning training (\u22647am - EARLY), day training (&gt;7am - DAY), and no training (REST).
