KNR 280 Exam 1 UPDATED ACTUAL Questions and CORRECT
Answers
Exercise Physiology A basis and applied science that describes, explains, and uses the body's
response to exercise and adaptation to exercise training to maximize human
physical potential.
Exercise planned, structured, repetitive movement intended to improve or maintain
physical fitness
Physical Fitness A set outcomes or traits that relate to the ability to perform physical activity.
Sport A form of physical activity which involves competition.
Physical Activity any bodily movement produced by skeletal muscles that results in energy
expenditure.
Kinesiology The study of physical activity
Mode What you are doing / what work out
Intensity How hard the activity is (light, moderate, vigorous).
Supramaximal All out, super tired after like 5-10 seconds
Maximal Time limit, super hard.
Submaximal Easy, like walking.
Relative workload Tapered to each person (i.e. pound for pound).
Absolute workload Same amount/number for everyone (ends up being harder for some and easier for
some).
Duration How long an exercise is.
Frequency How often.
Acute Short term.
Chronic Late in future.
Response Current.
Adaptation Over time.
, High-energy Intake can result in.... - Unwanted weight gain
- Chronic Disease
Low-energy Intake can result in... - Loss of muscle mass
- Loss of bone density
- Menstrual dysfunction
- Risk of fatigue
- Injury / acute illness
Total calories required varies per person because..................... 1. Body Mass or Size
2. Exercise or Vocational Physical Activity
- Resting Metabolic Rate
- Age
- Gender
- Genetics / Sex
- Body Composition
Nutrients a chemical that an organism needs to live and grow that is taken from the
environment.
Six Nutrients 1. CHO (carbohydrates)
2. Protein
3. Fat
4. Water
5. Vitamins
6. Minerals
Sources of Energy (macronutrients/substrates) 1. CHO
2. Fats
3. Proteins
4. Alcohol (bonus)
Caloric density for CHO 4 Kcals per gram
Caloric density for Fat 9 Kcals per gram
Caloric density for Protein 4 Kcals per gram
Caloric density for Alcohol 7 Kcals per gram
CHO (carbohydrates) - 45%-65% of diet
- CNS consumes a lot of CHO
- Primary fuel source
- ONLY anaerobic fuel source
- Required for fat metabolism
- Regulates protein metabolism
- Used in the form of glycogen or glucose
