The influence of evening electronic device use on sleep and performance in athletes

This thesis demonstrates that evening electronic device use may not impair sleep quality or reduce sleep duration in athletes, despite 30% of athletes reporting excessive sleepiness. Using an electronic device for 2 h prior to bedtime did not have any negative consequences on sleep quality or quantity in netball players. Additionally, avoiding electronic devices overnight during training camps did not improve sleep quantity or cognitive performance in triathletes or water polo players. Furthermore, shorter versions (3- and 5-min) of the Psychomotor Vigilance Test did not provide similar measures of cognitive performance compared with the 10-min test in basketball players.
