Poor Recovery and Increased Muscle Breakdown: Insufficient Sleep Part 2!

  • The importance of sleep is often underestimated in fitness, with focus usually directed at diet and exercise programs.
  • Insufficient sleep leads to decreased levels of anabolic hormones such as testosterone and IGF-1, which are crucial for muscle growth and recovery.
  • The loss of sleep doesn't just hinder muscle growth but increases muscle breakdown due to elevated cortisol levels, further inhibiting potential gains from training.
  • Sleep deprivation mimics some aspects of aging in its effects on muscle strength, size, and body composition due to hormonal changes.
  • Personal sleep needs vary, but a general guideline for adequate sleep is waking up naturally without the aid of an alarm.
