Abstract: A large body of scientific evidence holds that a combination of carbohydrates and protein/essential amino acids is more efficient than carbohydrates alone when in optimal muscle strength and size gains through resistance training is the goal. However, there is much less consensus on what the optimal timing of administration is, with conflicting reports regarding consumption of supplements before, during, and after training. To try and answer some of these questions, a study was conducted using 23 volunteers performing resistance training for 8 weeks, and consuming either a combination of carbohydrates and protein or carbohydrates alone. Measurements of body composition, limb circumference and strength were performed both before and after. No significant differences could were be found observed in any of the measurements between the two groups after 8 weeks of training. While this was unexpected, a closer look at the data, as well as an evaluation of the training methods and nutrient supplementation used in the study in comparison with by other studies in the field, revealed that issues such as nutrient composition, dosage and the training process (directly supervised or not) training may have a strong influence on the results of a training study. Thus, in order to conclusively answer the question of which training and nutritional strategy produces were the best results, first of all, a more standardized training methods are is required.
