Categories included in nutrition assessment
Food and nutrition related history
Anthropometric measurements
Biochemical data, medical tests, and procedures
Nutrition focused physical exams
Client history
Comparative standards
What conditions does the ACSM recommend a pre exercise evaluation for
Physically inactive individuals with cardiovascular, metabolic, renal disease, or for active individuals who develop symptoms of these
What are the most widely accepted standards in sports nutrition
Joint Position Statement on Nutrition and Athletic Performance
IOC Consensus Statement on Sports Nutrition
Waist circumference recommendations
Males: Less than 40 in (102 cm)
Females: Less than 35 in (88 cm)
Are Food Frequency Questionnaires relevant to athletes
No
Results have not been compared to biological markers and interpretation of results is difficult
What affects food choices and behaviors
Where an individual eats
Who purchased the food
Access to the food
Access to cooking facilities
Who the individual eats with
Stages of transtheoretical model
Precontemplation, contemplation, preparation, action, maintenance, termination
Website that contains description of transtheoretical models and techniques effective at each stage
UCLA Center for Human Nutrition
List challenges specific to the dietary assessment of the athlete
Periodized training cycles
Dietary manipulation (ex: carb loading)
Training days vs. competition days
Dietary supplements, sports foods, and products
Pre exercise and post exercise fueling patterns
Describe RQ and what does it measure
Respiratory Quotient
Relationship between volume of CO2 produced and volume of oxygen consumed
Estimates energy expenditure
What are the two most accurate energy prediction equations for athletes
Cunningham (requires measurement of lean body mass)
Harris Benedict
How to assess protein status
Nitrogen balance
Stable isotopes
Fractional synthetic rate
Retinol binding protein
Prealbumin
Albumin
Labs pulled for cardiovascular disease risk
Lipid profile
C-reactive protein (8-10 mg/dL)
Homocysteine (5-15 mmol/L)
What can affect urine specific gravity (USG) accuracy
Diet
Heavy exercise
High lean body mass
Ferritin increases in response to what
Vigorous physical activity
Inflammation
United States Olympic Committee (USOC) reference ranges for vitamin D and what version of vitamin D is measured
Toxicity >150
Optimal status 40-70
Normal status 30-80
Vitamin D Insufficiency 21-29
Vitamin D Deficiency </= 20
Calcidiol
USOC reference ranges for iron status
Stage 1 iron depletion
<35 ug/L ferritin
>115 g/L hemoglobin
>16% transferrin saturation
Stage 2 iron deficient non-anemia
<20 ug/L ferritin
>115 g/L hemoglobin
>16% transferrin saturation
>500 ug/L total iron binding capacity
Stage 3 iron deficient anemia
<12 ug/L ferritin
<115 g/L hemoglobin
<16% transferrin saturation
USOC recommends iron supplementation when transferrin levels fall below…
Females: 35 mcg/L
Males: 4 mcg/L
How does sports anemia occur
Increased blood volume dilutes hemoglobin
How does one calculate BMI
Kg/m^2
Lb -> kg = lbs/2.2
Ft -> m = Ft X 0.304
How to calculate RMR
Men:
(10 x kg) + (6.25 x cm) - (5 x age) + 5
Female:
(10 x kg) + (6.25 x cm) - (5 x age) - 161
What is higher, RMR or BMR and by how much
RMR is higher by about 10%
Percent weight by body part for calculating amputations
Arm - 5%
Foot - 1.5%
Below the knee - 5.9%
Above the knee - 8.1%
Whole leg - 16%
What are the ranges for urine specific gravity
Normal: 1.005 - 1.030
Well hydrated: <1.010
Minimal dehydration: 1.010 - 1.020
Significant dehydration: 1.021 - 1.030
Serious dehydration: > 1.030
