Sleep deprivation is a common issue in football, and it can significantly impact game results.<br> <strong>Objectives. </strong>This study examined how a sleep hygiene protocol impacts various football match PIs.<br> <strong>Methods. </strong>A tertiary team comprising twenty male university-level football players (average age: 22.2 &plusmn; 3 years; height: 167.6 &plusmn; 6.4 cm; weight: 62 &plusmn; 6.6 kg) completed a 4-week sleep hygiene intervention period (SHP). During the SHP, players followed at least ten sleep hygiene rules and completed a daily sleep diary. The performance indicators of the team and their opponents were recorded and analyzed over 14 matches, divided into a quasi-experimental repeated measures design (comprising five matches completed without the sleep intervention (nSHP), four matches with SHP, and again five matches with nSHP). The Pittsburgh Sleep Quality Index (PSQI) was utilized two weeks before SHP began, and three weeks into the intervention for subjective sleep measures.<br> <strong>Results. </strong>A significant decrease in overall PSQI scores (P = 0.03, g = 0.6) was noted. There were also significant positive changes in the number of dribbles (P = 0.004, g = 1.9, Mdiff = 47.3%), network passes (P < 0.001, g = 1.6, Mdiff = 37.9%), successful passes (P < 0.001, g = 1.3, Mdiff = 21.6%), and crosses (P = 0.02, g = 1.4, Mdiff = 28.6%) compared to nSHP. Successful passes were strongly linked with shots on target and network passes, while penalty-area shots were connected to dribbles (all P < 0.001).<br> <strong>Conclusion. </strong>In this cohort and setting, SHP was associated with improvements in several offensive PIs; however, findings are preliminary and require replication with objective sleep measures and more matches.</div> sleep hygiene, sleep, performance indicators, football, video analysis 0 0 http://aassjournal.com/browse.php?a_code=A-11-1561-2&slc_lang=en&sid=1 Adele Broodryk adele.broodryk@nwu.ac.za 100319475328460017592 100319475328460017592 Yes Physical Activity, Sport and Recreation Research Focus Area, Faculty of Health Sciences, North-West University, Potchefstroom, South Africa Michael Prevoo mikesprevoo10@gmail.com 100319475328460017594 0009-0006-7266-0595 No Physical Activity, Sport and Recreation Research Focus Area, Faculty of Health Sciences, North-West University, Potchefstroom, South Africa Mark Kramer mark.kramer@nwu.ac.za 100319475328460017593 100319475328460017593 No Physical Activity, Sport and Recreation Research Focus Area, Faculty of Health Sciences, North-West University, Potchefstroom, South Africa
