Training collegiate athletes during the early morning hours (6 a.m. or earlier) is poor practice based on scientific data.

Andy Galpin here highlights the mismatch between imposed early-morning schedules and physiological recovery needs. Research in chronobiology, particularly studies on circadian rhythms, confirms that physical performance and cognitive alertness are often suboptimal early in the morning, as body temperature is at its minimum and biological functions are not yet fully activated. Meta-analyses on athlete sleep show that sleep restriction, often caused by these early wake-up times, significantly impairs recovery, protein synthesis, and injury prevention. However, it is important to provide nuance: while pure performance is superior late in the day, adaptation to the schedule imposed by competitions (which often take place early) remains a pragmatic aspect that coaches must balance. The statement is therefore biologically sound, but it sometimes overlooks logistical constraints and the adaptation required by the sports calendar. In summary, the advice is well-supported by sleep and performance science, even if the reality on the ground often requires compromises.
