Key Points
• Protein Quality should be determined by the DIAAS
1. 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

Nutrient Timing
Diet – Workout Integration
• Optimal window of time to consume
nutrients that will maximize training
outcomes.
Figueiredo, AJP (2019)
Daily Meal – Activity Synchronization
I.
Design the protein pacing model based on
o Meal distribution (meal - activity synchronization)
o Amount and type of protein per meal
Determine the daily amount and type of per meal CHO ingestion
III.
Determine the daily amount and per meal FAT ingestion
IV.
Design the timing of ingestion per meal based on the kind of daily activities (training)

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…
