Questions and Answers

An athlete is trying to increase lean body mass while decreasing fat mass. Which strategy is MOST appropriate?

  • Establish a caloric deficit with adequate protein intake alongside a strength and conditioning program. (correct)
  • Establish a caloric surplus with a high protein intake without resistance training.
  • Establish a large caloric deficit and consume minimal protein.
  • Establish a small caloric surplus and focus on high fat intake.

What is the initial step a sports dietitian should take before recommending a supplement to an athlete?

  • Analyze the athlete's supplement stack.
  • Review the athlete's training regimen.
  • Evaluate the athlete's hydration habits.
  • Assess the athlete's current performance diet. (correct)

Why is electrolyte replacement important for athletes during endurance activities?

  • Electrolyte depletion signals the body to conserve fluid by increasing urine output.
  • Electrolytes prevent the formation of lactic acid, preventing muscle fatigue.
  • Electrolytes provide the primary fuel source for muscle contraction during low-intensity activities.
  • Sweat, a hypotonic solution, contains vital electrolytes that require replacement. (correct)

1A: Energy Metabolism key areas

  • Analyzing and interpreting available athletic performance and health data.
  • Designing nutrition strategies for active individuals, applying energy metabolism principles.
  • Explaining energy storage in skeletal muscle and tissues.
  • Describing oxygen transport in exercise and training.
  • Evaluating substrate use factors and exercise metabolism data.

  • Recount nutrition and exercise effects on health, performance.
  • Explain carbohydrate, fat, protein, and amino acid use during exercise training, competition, recovery.
  • Vitamin and mineral requirements for training/exercise.
  • Potential risks of excessive vitamin/mineral supplementation.
  • Antioxidant function in exercise, recovery, long-term adaptations.
  • Describe the efficacy of vitamin and mineral supplementation on health and performance.

Energy currency of the cell

  • Adenosine Triphosphate [ATP]: nitrogenous purine base, pentose sugar, and three phosphates
  • Use: fuel for all processes within cells requiring energy
  • Provides: energy to perform “work” results from the ATP releasing energy and activating muscle contraction through transferring the energy from ATP to the contractile elements in muscle [actin and myosin]
  • Once used, ATP must be resynthesized to provide a continuous supply of energy
  • Occurs from CP or creatine phosphate (also referred to as Pcr or Phospocreatine) through the phosphagen system, anaerobic glycolysis and aerobic metabolism Every muscle contraction requires ATP
  • All metabolic systems work concurrently; contribution of each depends on demand and oxygen availability

Factors determining use of of Fuel Source

  • Exercise intensity, duration, level of training, composition of diet.

Four Major Fuel Sources:

  • Glycogen, plasma glucose, intramuscular triglycerides and plasma free fatty acids
  • NOTE: amino acids from protein breakdown can be utilized but are conserved at all costs

ATP-PhosphoCreatine system

  • PC is stored in skeletal muscle.
  • Key part of the anaerobic system.
  • Needed during high intensity and explosive movements.
  • Rapid source of ATP but does not last for more than a few seconds at a time.
  • PC Creatine Kinase Cr + Pi + Energy

Anaerobic glycolysis

  • Only anaerobic fuel source is glucose
  • Dietary intake
  • Stored glycogen.
  • Glucose is used in the first few minutes of continuous, intense activity via anaerobic glycolysis.
  • 1 6C glucose 2 3C pyruvates
  • Pyruvate converts to lactate Reduces enzyme activity for glycolysis
  • Results in skeletal muscle fatigue
  • Lactate enters the Cori Cycle.

Aerobic metabolism

  • Also known as oxidative phosphorylation (OxPhos) and is an energy efficient system
  • Predominates during most endurance exercise
  • Oxidation of glucose results in the formation of acetyl CoA in the presence of oxygen
  • Acetyl CoA condenses with oxaloacetate and enters the Krebs cycle.
  • Krebs cycle produces hydrogen molecules which get transported to the electron transport chain to generate ATP.

Muscular contraction: doing the work

  • Motor unit=single nerve and the muscle fiber group that it innervates
  • Muscle fiber=muscle cell
  • Actin: thin filament in the myofibril
  • Myosin: thick filament
  • Type I muscle fiber: “slow twitch", aerobic endurance, use carbohydrate and fat through aerobic energy during low intensity activity
  • Type II muscle fiber: “fast twitch", in use during high-intensity, anaerobic work with poor capacity for aerobic endurance; sub-types are Type IIA, IIX and IIC.

Cardiorespiratory System

  • Controls ventilation for gas exchange and waste removal.
  • Heart rate, stroke volume, cardiac output, and VO2 max increase with exercise intensity and training.
  • Hemoglobin transports oxygen.
  • Myoglobin accepts oxygen from hemoglobin within muscle
  • Heart rate: beats per minute; normal range 60-100 bpm
  • Tachycardia: >100 bpm [increased over normal]
  • Bradycardia: <60 bpm [decreased from normal]
  • Stroke volume: blood volume per heart beat
  • Cardiac output: heart rate X stroke volume; muscle demand is ≈15% of blood pumped during rest, increases to 80% during exercise
  • VO2 max: mL x kg¯¹ x min¯¹; measures maximum rate of oxygen consumption.

Macronutrients

  • must be oxidized to release energy of Adenosine Tri-Phosphate (ATP)

Carbohydrates

  • Provides ATP during anaerobic and aerobic metabolism.
  • Stored as glycogen in the liver and muscle.
  • Predominates during high-intensity; also supplies fuel during endurance activity along with fat (protein to a lesser extent).
  • Oxygen-efficient fuel source and produces ATP quickly.

Fat/Lipid

  • Can only be completely oxidized during aerobic metabolism.
  • Stored as triglyceride in the adipose tissue and muscle tissue.
  • Not oxygen-efficient.

Crossover Concept

  • At low intensity and rest, fat is used as a fuel source; at higher intensity, carbohydrate predominates.

Additional Notes

  • Short term fatigue is results from muscle lactic acid build up
  • Long term fatigue is a result of glycogen depletion

Daily needs carbs "in a nutshell"

  • Low-intensity or skill based: 3-5 g/kg/day
  • Moderate-intensity, ~60 minutes/day: 5-7 g/kg/day
  • High-intensity, ~1-3 hours/day: 6-10 g/kg/day
  • Very high-intensity, ~4-5 hours/day: 8-12 g/kg/day

Protein In a Nutshell

  • Endurance: 1.2-1.4 g/kg/day
  • Resistance/Strength-based: 1.6-2.0 g/kg/day

Loading

  • Day 1 & 2: no training/rest day, 10-12 g/kg/day carbs
  • Day 3: Event/Competition, same as the usual carb guidelines listed above for intake before, during and after competition

Fats

  • Follow AMDR: 20-35% total energy from fat
  • <10% saturated fat
  • <1%trans-fat
  • Emphasize mono-unsaturated and poly-unsaturated fats [emphasize omega3s for the anti-inflammatory properties; examples of omega 3s are EPA & DHA].

Key micronutrients to consume

  • Vitamin E
  • Vitamin C
  • Vitamin A/beta-carotene
  • Selenium
  • Iron
  • B12
  • B6
  • Folate
  • Vitamin K
  • Calcim.

1b: Fueling for training and competition key areas

  • Designing nutrition plans for individuals/groups, incorporating exercise-specific carbohydrate recommendations.
  • Evaluating special considerations related to carbohydrates, fat intake, fat storage, and protein.
  • Design nutrition plans with exercise-specific protein recommendations.
  • Design nutrition strategies for pre/during/post-workout, competition, and recovery.
  • Observing athletes for movement/energy expenditure/training patterns/fueling, hydration habits.
  • Assessing products, foods, meals compliance with governing body guidelines.

Important note

  • Always take clinical nutrition skills with you and incorporate The Nutrition Care Process!

Key Steps in Nutrition Management

  • Step 1: Nutrition Assessment
  • Step 2: Nutrition Diagnosis with PES
  • Step 3: Nutrition Intervention
  • Step 4: Monitoring and Evaluation

Remember

  • Athletes should: consume 3 balanced meals and 2-3 snacks. Eat to support training.
  • Focus on whole grains, fruits, vegetables ["eat the rainbow"], lean protein and healthy fats, not processed foods.
  • Make intake for what they need: Rest Days, Easy Training & Weight Loss: Plate mostly fruits & vegetables, ¼ lean protein & ¼ healthy grains.
  • Moderate Training: Balance all food groups about 1/3 of the plate
  • Hard Training or Competition: ½ the plate healthy grains, ¼ lean protein, ¼ fruits & veggies

Water, Fluid, and Water Balance

  • Human body must have adequate water, or dehydration effects can be felt in as little as 1-2% body weight
  • Factors determining fluid needs: body size, metabolic rate, diet composition, duration, intensity, physiology, environmental temperature, fitness, and acclimation to heat
  • Sodium as primary electrolyte lost stimulates thirst, palatability/less urination
  • Human body has several different mechanisms for cooling including radiation, evaporative, conductive and convective
  • Sources of water loss are from skin, urine, feces, sweat and the respiratory tract
  • Goal of water volume is lighter pee and urination every 2-4hrs
  • Sweat testing helps to determine an individuals losses

Fluid in a Nutshell

  • Pre: eat and drink something ~2 hours before event
  • During: Most important is stable blood glucose <30 Min: none
  • 30-75 Min: water but water every 15 2 –5 hrs and over: need more water with carb

Symptoms of dehydration include

  • Dark urine, small volume of urine: 1-3 adequately hydrated
  • Elevated heart rate
  • Headache
  • Fatigue and difficulty concentrating

Alcohol and Athlete Performance challenges include

  • diuretic causing dehydration/heat issues
  • impairs intake after workout and decreases muscle building

Guidelines and Important Note

  • Dietary ingredients: vitamins, minerals, amino acids, herbs/botanicals
  • DSHEA defines under FDA "food" not a "drug”
  • "Proprietary Blend" is a red flag
  • Evaluations of effectiveness and safety are not evaluated prior to market and not required by manufacturer
  • The NCAA sets the rules

Key Supplement points

  • If it sounds too good to be true- don't
  • Athlete must be is eating well and making adequate progress through exercise
