Summary

This randomized controlled trial aimed to investigate the effects of casein supplementation timing on post-exercise recovery and exercise performance in trained football players. Participants were allocated into three groups: pre-sleep casein ingestion, post-exercise casein ingestion, and control. The study compared the effects of pre-sleep and post-exercise casein intake on anaerobic performance, agility, and recovery markers following a standardized high-intensity resistance training session.

Micellar Casein

Participants consumed 30 g of micellar casein powder dissolved in 300 mL of water. Supplement timing varied by group: Post-Exercise Casein Ingestion Group (PECIG): Taken 10-15 minutes after completing the standardized high-intensity resistance training session. Pre-Sleep Casein Ingestion Group (PSCIG): Taken 30-60 minutes before bedtime on the same day as the training session. The control group received no supplementation. All supplements were prepared and monitored by the research team to ensure dosage accuracy and participant compliance.
