Sleep in Collegiate Baseball Players

Sleep is an essential biological function that impacts nearly every aspect of an athlete's physical and mental health. For athletes, the importance of high-quality sleep cannot be overstated, as it plays a critical role in performance, recovery, and overall well-being. Sleep supports muscle recovery by promoting protein synthesis and the release of growth hormones, essential for healing after intense physical exertion. Furthermore, adequate sleep is crucial for maintaining cognitive sharpness, decision-making abilities, and emotional regulation-all of which are necessary for optimal athletic performance. The study will assess both sleep quality and quantity in baseball players at Columbia University. These tools will help quantify key sleep metrics, including sleep duration, latency (the time it takes to fall asleep), and the number of awakenings during the night. Similarly, the study will analyze dietary patterns using the Automated Self-Administered 24-Hour Dietary Assessment (ASA24), tracking nutrient intake, meal timing, and the consumption of ultra-processed foods. These assessments will establish a baseline from which to measure improvement post-intervention. The intervention will focus on improving diet, time in bed, and light exposure to improve sleep, diet, and performance in collegiate baseball athletes.

Primary outcomes

  1. Athletic performance (position-specific for batters and pitchers)

    Time frame: pre and post intervention (4-6 weeks)

    Batters: Baseball radar gun, outcome is exit velocity (speed at which ball leaves the bat, in miles/h) Pitchers: Baseball radar gun measuring velocity (miles/h)

  2. Sleep quality

    Time frame: Nightly for 6 weeks

    Duration (h:min)

  3. Sleep quality

    Time frame: Nightly for 6 weeks

    Sleep stage (%REM, %Deep sleep)

  4. Dietary quality

    Time frame: pre and post intervention (4-6 weeks)

    3-day food recalls (ASA-24)

Secondary outcomes

  1. Generalized Anxiety Disorder (GAD-7)

    Time frame: pre and post intervention (4-6 weeks)

    7 questions, 0-3 points each (not at all to nearly every day); global score 0-21, higher score is worse

  2. Patient Health Questionnaire-9

    Time frame: pre and post intervention (4-6 weeks)

    9 questions, 0-3 points each (not at all to nearly every day); global score 0-27, higher score is worse

  3. Sport Anxiety Scale-2

    Time frame: pre and post intervention (4-6 weeks)

    4-point Likert scale (not at all to very much); global score 5-20, higher score is worse

  4. Pitching accuracy

    Time frame: pre and post intervention (4-6 weeks)

    Ratio of strikes to balls (pitchers only)

  5. Isometric wall push

    Time frame: pre and post intervention (4-6 weeks)

    Hand-held dynamometer (pounds) (pitchers only)
