Exam 1 Flashcards
What are the 4 things to keep in mind depending on the season and what are the 4 types of seasons
Training goals, body comp goals, energy (calorie) intake and nutrition intake.
Prior to the season, pre-season, post-season and off-season
Sports nutrition affecting Optimal Performance
- Critical role in maximizing training adaptations and minimizing fatigue
- Essential nutrients play a role in cognitive function, reaction time and coordination
Sports nutrition affecting Enhances Recovery
- Intense exercise leads to muscle damage and inflammation
- Adequate nutrition can help decrease inflammation, replenish energy stores and provide nutrients for muscle repair and growth
Sports nutrition affecting Immune Function and Injury Prevention
- Exercise can suppress the immune system, increasing risk for illness and infection
- Certain nutrients building blocks for the growth, repair and maintenance of bones, muscles, tendons and ligaments
Sports nutrition also affects….
- Overall health and longevity
- Weight Management and Body Comp
What does poor sports nutrition affect?
- Decreased performance
- Increased risk of injury
- Impaired immune function
- Delayed recovery
- Impaired mental and emotional wellbeing (affected by micronutrients)
- Decreased muscle mass and inability to maintain weight (cal def will cause overtraining; cal intake will cause fat gain)
- hormonal imbalances (disrupt recovery and body comp)
What happens when calcium, bone density and vitamin D are lacking?
Decreases bone density and increases risk for stress fracture
Insufficient carb intake will lead to what?
Increase muscle glycogen leading to muscle tear and strain
2-3% of what can be lost through sweat loss and negatively affecting performance?
Body mass
Sports drinks or electrolyte replacements intense or prolonged exercise will do what?
Help rehydration
Pre-exercise meal
2-3 hours before exercise
Pre-workout snack
30-60 min
Post-workout snack/meal
30-60 min
What is the difference between nutrient density and balanced diet
Nutrient density: refers to concentration of essential nutrients given for amount of food or beverages relative to the energy (cal) provided by the food (Includes whole foods, minimally processed foods)
Balanced Diet: Refers to the consumption of a variety of foods from different food groups in appropriate proportions to provide the necessary nutrients for overall health and well-being
RDA
recommended dietary allowance
AI
adequate intake
UL

EAR
Estimated Average Requirement
Acceptable Macronutrient Distribution Ranges (AMDRs)
guidelines established by IOM which provide recommendation for distribution of macronutrients
Carbs: 45-65%
Proteins: 10%-15%
Fats: 20-35%
