Summary

The goal was to evaluate the influence that chronic sleep restriction may have on football players tactical performance during small-sided games. By using a relative sleep restriction (i.e., by reducing the normal sleep duration by 15%) instead of an absolute sleep restriction (e.g., 3-4 hours), different sleep schedules were applied, according to the players individual sleep profile. It was hypothesized that the player's performance would be impaired, particularly their tactical behaviors when performing a 4x4 small-sided game format.

Conditions

  • Sleep Restriction

Interventions

BEHAVIORAL

Sleep restriction

During the intervention period (i.e., 9 consecutive days), the intervention group started the sleep protocol, sleeping only the quantity of hours defined for their individual chronic partial sleep restriction (15% of the usual sleep time). The amount and quality of sleep obtained were daily monitored through actigraphy devices, and all the players filled in a sleep diary when they woke up. During this period, players performed the SSGs in two different moments (moment 1 and moment 2), interspersed by 4 days.
