Carbs after workouts matter

Carbohydrates are the sugar your body stores as glycogen, the fuel packed into muscle for hard sets and long runs. After exercise, eating carbohydrate helps refill those stores, and sports nutrition groups say that matters for recovery. (link.springer.com) The International Society of Sports Nutrition said post-exercise carbohydrate is an efficient way to maximize glycogen replenishment after training. Its 2017 position stand said rapid refueling matters most when the next workout is less than four hours away. (link.springer.com) That same position stand said athletes trying to restore glycogen quickly can use about 1.2 grams of carbohydrate per kilogram of body weight per hour. It also said combining about 0.8 grams of carbohydrate per kilogram per hour with 0.2 to 0.4 grams of protein per kilogram per hour is another option. (ncbi.nlm.nih.gov) Protein and carbohydrate do different jobs after training. A 2021 meta-analysis found carbohydrate plus protein did not raise glycogen synthesis more than carbohydrate alone when calories and carbohydrate intake were matched, but protein still supports muscle protein synthesis. (pmc.ncbi.nlm.nih.gov) That is why foods like rice and potatoes keep showing up in recovery advice: they are straightforward carbohydrate sources that can be eaten in useful amounts. The research focus is the carbohydrate dose, timing, and total daily intake, not a special muscle-building property unique to either food. (link.springer.com) The American College of Sports Medicine, the Academy of Nutrition and Dietetics, and Dietitians of Canada said in a joint position statement that athletic performance and recovery are improved by well-chosen nutrition strategies. That guidance treats recovery meals as part of an overall eating plan, not a single “anabolic window” trick. (jandonline.org) The urgency depends on the athlete. The International Society of Sports Nutrition said high-volume exercise depletes glycogen the most, and the biggest payoff from fast carbohydrate intake comes when training is intense, prolonged, or repeated in the same day. (link.springer.com) For someone lifting once a day and eating enough over 24 hours, the exact post-workout food is less important than meeting total carbohydrate and protein needs. For someone with a second practice, a game, or another hard session in a few hours, rice, potatoes, fruit, or other easy-to-digest carbohydrate can do practical recovery work. (link.springer.com) The bottom line is simpler than most gym nutrition debates: protein helps rebuild tissue, and carbohydrate helps refill the tank. After a hard workout, both can belong on the plate. (pmc.ncbi.nlm.nih.gov)
