Protein Quality
Amino Acid Content + Protein Digestability
Glycemic Load
GI of food X grams of carb per serving/100
Saturated fatty acids vs unsaturated fatty acids
Saturated: no double bonds
Unsaturated: Double bonds
LDL, HDL, total cholesterol levels
LDL want < 100
HDL want > 60
Total want < 200
Within 30 minutes after aerobic exercise what should you eat?
1.5 g of high GI foods to stimulate glycogen resynthesis
Fluid intakes during exercise
Children weighing 88 lbs: 5 oz every 20 minutes
Children weighing 132 lbs: 9 oz every 20 minutes
Adults: sports drink with 20mEq sodium, 2-5mEq potassium, and 5-10% carbs
Precompetition Food and fluid recommendations for Aerobic Endurance Athletes
4 hrs: 1-4 g carbs per kg of BW & .15-.25 G protein per kg of BW
2 hrs: 1 g carbs per kg of BW
1 hr: 0.5 g carbs per kg of BW
Carbohydrate Loading Guidelines
8 - 10 g/kg/BW 3 days prior
10 - 12 g/kg/BW 1 & 2 days before
How should aerobic endurance athletes consume carbohydrates before an event?
Should mix together to increase absorption rate
Carbohydrate requirements for endurance athletes vs strength/power athletes
Endurance: 8-10 g
Strength/power: 5-6 g
Protein Requirements for endurance athletes vs strength/power athletes
Endurance: 1.0 - 1.6 g
Strength/power: 1.4 - 1.7 g
To stimulate hypertrophy what are the carbohydrate and protein requirements?
Carbs: 30-100 g of high GI
Protein: 20-30 g of high leucine content every 3-4 hours
BMI Equation
weight (kg)/ (height (m)^2)
BMI for underweight, normal, overweight, obese
Underweight: <18.5
Normal: 18.5 - 24.9
Overweight: 25 - 29.9
Obese: > 30
- Class 1: 30 - 34.9
- Class 2: 35 - 39.9
- Class 3: > 40
BMI rankings for children
> 5th percentile : underweight
5th percentile - < 85th percentile : healthy
85th percentile - < 95th percentile: Overweight
= or > 95th percentile : obese
