Yоu аre stаff оn the vоlleybаll team. The coach says that he understands having a moderate amount of carbohydrates in his athletes' diet is important, but he wonders if you think it is important to "carb load" before the match or not. Please explain your answer, addressing: 1. the dominant energy systems likely at play during a volleyball game 2. substrate(s) used 3. why this would or would not warrant carbohydrate loading (muscle glycogen supercompensation).
