Studies have established a link between sleep quantity and performance level in any skill-based sport. It is the central nervous system (CNS) and in particular, the brain, that's intimately associated with control of the body and athletic performance. The body and mind need rest to recover from the fatigue brought on by intense training. Sleep provides the opportunity for the body and mind to recharge from hard training.
Cognitive and physiological impairment inevitably results when the CNS is fatigued. Brain scans have indicated that lack of sleep affects blood flow within the brain. The lack of blood within the brain can affect cognitive and physical performance. Cognitive impairment is characterized by an inability to focus, memory loss, increased anxiety, decreased reaction time, decreased motivation, irritability, and emotional instability. Physiological impairment is characterized by physical exhaustion, increased susceptibility to infections, fatigue and decreased speed and power.
Catabolic hormones (e.g., epinephrine, norepinephrine, cortisol) are emitted due to sleep deprivation, inhibiting muscle growth. On the other hand, anabolic hormones (e.g., testosterone, human growth hormone) are released when adequate sleep has occurred, enhancing muscle growth. Performance potential is therefore predicated on sleep quality and quantity.
Here are some tips to get better quality sleep:
