IAA composition/density (g of IAA per 100 kcal >2.2) 2. Digestibility (presence of antinutritional factors) 3. Bioavailability (anti-physiological factors) • DIAA is the most important nutritional factor impacting on whole body protein balance. • DIAA does not consider the impact of exercise! • The DIAA to support RT adaptations/outcomes should be >1 CHO Ingestion in Athletes (g/kg BM) Low intensity or skill-based activities Moderate (1-h), Mod-high (intermittent) long-lasting mod-high int 3-4 5-7 Hypertrophy 8-10 12 Post-workout glycogen replenishment (exhaustive) ~1-1.2 g/kg? 0 <15-20 ~1-1.2 g/kg 120 ~0.8 -1 g/kg 180 ~0.8 -1 g/kg 240 min Glycogen replenishment rate >7 mmol/h (~1.4 g/kg/h) ~4 mmol/h (~0.8 g/kg/h) CHO type Fast Modified CHO ↑ Mol-W ↓ Osm + Fructose CHO multi-transportable (food) Piehl et al.

(2013) Key points! Training is the essential stimulus Diet can maximise training-induced outcomes by appropriately determining: i. Energy (e.g., + ~500 kcal/d for hypertrophy) ii. PROT (≥1.6 to 2.2 g/kg/d) iii. CHO (4 - 7 g/kg/d) iv. Fat (≥ 0.5 - 2 g/kg/d) v. Micronutrients and fluids intake • Optimal meal-activity synchronization (diet timing) • Synergic ingredients: o HQP with high IAA density (IAA-to-100 kcal= >2.2 ), ü animal or specific blend of plant-based protein (fortified with the limiting AAs) o Creatine (e.g., 100 mg/kg BM/d) o Fast CHO (post workout) o EFA, etc… Thank you!!
