Nutrition and Injury Recovery Rates

The Bad News

  • Immobilization due to injury can cause up to 5% muscle mass loss in the first two weeks
  • It can take 3X length of disuse to regain muscle mass

Basal Metabolic Rate (BMR) = amount of energy it takes to live (not including training).

  • BMR can increase 20% with a serious injury
  • BMR can increase 50% with surgery

Anabolic Stimulus = Any signal (like eating and training) given to your muscles or tissue to grow.

Ways to combat Disuse Atrophy - Nutritionally

Essential Amino Acids (EAA) = 9 Amino Acids your body cannot make. Must be Eaten.

  • 40g Whey Protein contains 16g of Essential Amino Acids
  • Recommendation: 3X per day between meals of 40g Whey Protein plus 30g Carbohydrate supplement. 600 extra calories to maintain positive daily energy balance due to healing process.
  • Similar supplementation in animals increased tissue healing 3X!
  • Omega-3 Fatty acids increased response to anabolic stimulus

Ways to combat Disuse Atrophy - Physically

  • Low Level Contractions
  • 20 contractions at 80% 1 Rep Max every other day
  • Even use of an electrical stimulator on muscles helps

Bottom Line

  • Maintain Positive Energy Balance. KEEP EATING!
  • Get all 9 Essential Amino Acids via food or supplements (40g Whey + 30g Carbs 3X per day)
  • Example = A smoothie with 40g Whey + 1 large banana
  • Low level contractions every other day of effected muscles
