Exercise Prescription
Adults should complete at least this many minutes of moderate-intensity physical activity per week to achieve substantial health benefits.
150 minutes
Heat cramps should be treated with
Rapid sodium replenishment
During acute altitude exposure, the cardiac output increases due to...
Increased heart rate
For men, a body fat percentage at or above this level falls into the obese classification.
25%
This condition involves three components: disordered eating, loss of the menstrual cycle (amenorrhea), and decreased bone mineral density.
Female Athlete Triad
These six components make up the FITT-VP principle used to develop an individualized exercise prescription.
frequency, intensity, time, type, volume, and progression
Muscle contractile forces decrease in what climate
Cold
The percentage that VO2 drops for every 1000 m ascent above 1500
10%
This body composition assessment uses air displacement plethysmography inside a sealed chamber to measure body volume and calculate body density.
Bod Pod
This is the most abundant mineral in the human body.
Calcium
For aerobic exercise, intensity should be at least this percentage of VO₂ max
50–60%
During prolonged exercise in the heat, the variable that increases due to dehydration is..
Heart Rate
Increased pulmonary ventilation during acute altitude exposure is stimulated by
Chemoreceptors
This body composition assessment method estimates body fat by measuring how easily electrical current travels through body tissues.
Bioelectrical impedance analysis (BIA)
This category of amino acids can be synthesized by the body and does not need to be obtained exclusively through the diet.
Nonessential amino acids
This method calculates training heart rate by adding resting heart rate to a percentage of heart rate reserve (HRmax − HRrest).
Karvonen Method
Fluid and salt loss from blood to skin,
accompanied by fatigue, nausea, vomiting & fainting
Heat Exhaustion
This measurement increases with heat acclimatization, indicating that working muscles extract more oxygen from the blood.
Arteriovenous oxygen difference (a-v)O₂
This component makes up approximately 70–85% of total body mass, includes skeletal muscle, bones, organs, and fluids, and is a primary determinant of BMR.
Lean Body Mass
This is the approximate number of kilocalories in 1 pound of body fat.
3,500 kcal
ACSM recommends this range of MET-minutes per week for overall physical activity volume.
500–1,000 MET-minutes
More dilute sweating during heat acclimation helps prevent excessive loss of this important electrolyte.
Sodium
This type of exercise is most negatively affected by altitude due to decreased oxygen availability and reduced VO₂ max.
Aerobic exercise
Skinfold measurements use the assumption that approximately this percentage of total body fat is stored as subcutaneous fat.
50%
This percentage of total daily calories should come from carbohydrates according to the Acceptable Macronutrient Distribution Range (AMDR).
45–65%
