Nutrition can seem very complicated, but it doesn’t have to be! Understanding basic nutrition fundamentals is an important starting point for anyone interested in taking charge of their health and impacting their performance as an athlete. In this presentation, we’ll cover the basics of nutrition for health and sport, discuss “trending” nutrition strategies, their implications and considerations for training and performance outcomes, as well as review practical applications for implementation in everyday life.
Introduction: Nutrition Basics
Types of Nutrients
- Needed by the body in large quantities.
- Protein, Fat & Carbs
- How we Classify Calories in Food.
- Needed by the body in relatively smaller quantities.
- Vitamins, Minerals, Antioxidants & Phytonutrients.
- The chemicals found in trace amounts of food.
- Drives high intensity exercise.
- Fuels our muscles.
- Brain requires 130g of glucose per day.
- Limited body stores: ~500g of carbohydrates
- (needs replenishment pre/post workout)
- Recommendations range from 45-65% of total daily calories.
SIMPLE CARBOHYDRATES VS. COMPLEX CARBOHYDRATES
- Rapid digestion
- Quick boost of energy
- Great for topping off stores before exercise
- Fruits (bananas)
- Longer Lastings Energy
- Have fiber for slow release of energy
- Majority of daily carbohydrate intake should be complex.
- Starchy Vegtables
- Whole grains (brown rice, oats)
- High fiber fruit
- Builds and repairs muscle tissue
- Key for bone health
- Improves fullness and satisfaction of snacks and meals
- Provides structure and support
- 1.2-2.0 g/kg BW (high quality)
- 0.3 g/kg BW every 3-5 hours
Timing and distribution of protein ingestion during prolonged recovery from resistance exercise alters myofibrillar protein synthesis.
Sample Meal Plan
Oatmeal w/ nuts, milk, seeds, berries & greek yogurt.
Egg & veggie scramble w/ turkey, beans, cheese and english muffin.
Tuna pouch w/ edamame
Cottage cheese w/ honey and fruit.
Rice/Quinoa bowl w/ chicken, beans, kale and vegetables.
Deli turkey or chicken on whole wheat wrap w/ veggies, pretzel + apple.
Whole grain bread w/ peanut butter and fruit + 8 oz milk
Oatmeal, energy bites w/ pb, banana and chocolate chips + honey.
Smoothie with greek yogurt, fruit, spinach and dates.
Banana, milk + protein powder.
Turkey meatballs w/ whole wheat pasta, tomato sauce and salad.
Lean beef burgers w/ cheddar cheese, avocado on whole wheat bun with sweet potato fries and green salad.
- Energy dense nutrient and important part of diet for athletes
- Fuels long, lower intensity workouts
- Important for hormone production
- Helps provide cushion for organs
- Recommendations range from 20-35% of total daily calories
- (<20% may limit essential nutrient intake)
Fueling Recommendations for Sports & Performance
Fueling During Exercise
Eating Patterns and the performance benefits
- Help individuals lean out or loose body fat which can aid in performance
- Improve diet quality – eliminate junk food, fast food and less nutritious foods.
- Renew focus, energy and confidence to meet a goal
- Strict rules and guidelines to take out the “thinking” in meal planning and gives structure.
Eating Patterns and the performance Dilemma
- Elimination of entire food groups takes out essential nutrients required for optimal performance.
- (No Carbohydrates can lead to a drop in energy, performance and recovery.
- (No Animal Proteins can make it challenging to achieve protein needs for strength and recovery.
- Restrictive eating patterns pose challenges when eating with family and loved ones.
- Long-term adherence is questionable due to time constraints, food restrictions, etc.
Common issues with an Increase in Dietary Restrictions
- May require more time, effort and meal planning
- May increase risk of nutrient deficiencies
- Can impact performance
- Is likely not sustainable long term
Weight Management & Weight loss Considerations
- Health / Nutrients
- Current Diet “Cleanup” (Primary Macronutrients. I.e. Higher Quality foods)
Weight Loss Strategies
Avoid Low Calorie Diets
Restricting food intake for quick weight loss results may be tempting but it can result in the following:
- lowered lean tissue and muscle strength
- lowered glycogen stores, leading to less energy for performance
Increase protein intake (within reason)
- With caloric restriction, increase protein helps preserve lean body mass (2g/kg bw)
- Increase in protein equals and increase in satiety
Build meals around nutrient-dense foods
- Fruits & Vegetables, whole grains, beans & legumes, lean meats, poultry & seafood, nuts & seeds, eggs and low fat dairy
Increase foods high in water and fiber
- Greater volumes of food equals greater satiety with fewer calories
- Fiber can increase satiety, “waste disposal” feeds healthy gut bacteria.
- (fruits & vegetables, beans & legumes, and whole grains)
Nutrition 101: Key Takeaways
Prioritize your health. Always!
Eat real food. (Don’t overcomplicate things)
Carbs are important! Adjust to physical demands.
Space protein out throughout the day (20-30g every ~3-4 hours)
Eat something before and after training. Carbs & Protein are key!
Consider strategy, timing & performance when it comes to weight management.
Formulate a nutrition game plan for the day ahead.

A Virginia native, she attended Virginia Tech for undergraduate school where she received dual degrees in Human Nutrition, Foods and Exercise as well as Spanish. During her time there, she competed on the University’s club lacrosse and triathlon teams, as well as discovered CrossFit and obstacle course racing (OCR). Four months after her first competitive OCR, she placed second at the 2014 Spartan Race World Championship in Killington, Vermont, and signed her first pro-team contract shortly thereafter. Corinna spent the next 2.5 years (including her final semester of school) racing professionally all around the continent.
