Not much research has been done on the effects of carbohydrate ingestion and its relationship to resistance training. Carbohydrate ingestion during or immediately after a training session significantly increases postexercise insulin and gH levels, and can possibly suppress postexercise cortisol levels. This may have a beneficial effect on recovery and on protein synthesis and muscle hypertrophy.
Research is needed to see whether an effect exists.
