The post-exercise period is characterised by elevated muscle protein synthesis rates, enhanced glucose uptake, and increased sensitivity to nutrient delivery. Consuming the right nutrients in the right quantities within this window does not require obsessive timing but does have a meaningful effect on recovery quality, particularly for adults over 35 who already have anabolic resistance.
The Protein Priority
Consuming 35 to 40 grams of high-quality protein within two hours of completing a resistance training session consistently improves muscle protein synthesis rates compared to delaying protein intake. For adults over 50, this dose is particularly important because of the higher leucine threshold required to overcome anabolic resistance. Whey protein is the most rapidly absorbed and has the highest leucine content of any protein source, making it practically convenient post-training. Whole food alternatives including Greek yoghurt, eggs, or chicken are equally effective when consumed in adequate quantities.
Carbohydrates: Context-Dependent
Carbohydrates in the post-exercise window serve primarily to replenish glycogen stores. For endurance athletes or those performing high-volume training, rapid glycogen resynthesis is a priority and consuming 1 to 1.5 grams of carbohydrate per kilogram body weight alongside protein optimises this. For adults performing resistance training three times per week or fewer, glycogen resynthesis is less urgent and carbohydrate timing is less critical than protein.
What to Actually Eat
- Greek yoghurt with fruit: 35 to 40 grams protein from a large portion, rapid absorption, carbohydrates from fruit for glycogen
- Salmon with rice and vegetables: complete protein source with anti-inflammatory omega-3, carbohydrates for glycogen replenishment
- Chicken breast with sweet potato: leucine-rich protein, moderate carbohydrates, practical and accessible
- Whey protein shake with milk and a banana: rapid, portable, convenient for those training away from access to whole food
