RED & WHITE MUSCLE DIFFERENCES


Red & White Muscle Differences

University of Michigan researchers exploring the relationship between muscle type and metabolism believe the white muscle built up through resistance training helps control blood sugars. An analysis of data published in the journal Nature Medicine suggests that a protein called BAF60c might play an important role in the formation of white muscle

Red muscle is prevalent in athletes who engage in long-duration endurance exercise. The mitochondria rely mostly on fat oxidation to generate ATP for energy. White muscle uses glycogen as the primary fuel source for short but intense bursts of power, which is why this type of muscle is prevalent in sprinters, body builders and weight lifters.

True Strength Moment: Although muscle type might play an important role in metabolism, your choice of carbohydrates can have a more immediate impact. To avoid the surge of energy and crash associated with fast-digesting sugary carbohydrates, choose complex carb sources like asparagus, sweet potato, oatmeal and brown rice. Consumed in small quantities at feedings spread every 2 to 3 hours apart, complex carbs can provide sustained energy to those who rely on strength and power.
