Final Flashcards
what nutrients are listed on the food label?
total fat, saturated fat, trans fat, cholesterol, sodium, total carbohydrate, dietary fiber, total sugars, added sugars, protein, vitamin D, calcium, iron, and potassium
why are these nutrients listed on the food label?
It shows you some key nutrients that impact your health
which ingredients are listed first on a food label?
the ingredients are listed in order of predominance, with the ingredients used in the greatest amount first, followed in descending order by those in smaller amounts
anaerobic energy system
- lasts around two minutes
- involves ONLY carbohydrates (CHO, FAT)
- does NOT require oxygen
- Also known as anaerobic glycolysis
1g of CHO=
4kcal
1g of fat=
9kcal
1g of PRO=
4kcal
1g alcohol=
7kcal
aerobic energy system
- lasts more than 2 min.
- involves all macronutrients (CHO, FAT, PRO)
- requires oxygen
three energy systems
phosphagen, anaerobic, aerobic
which fuel is predominantly used in the phosphagen system?
creatine phosphate
which fuel is predominantly used in the anaerobic system?
glucose
which fuel is predominantly used in the aerobic system?
carbohydrates, protein, or fat
activities that are anaerobic
- powerlifting
- sprinting
- hockey
activities that are aerobic
- dancing
- cross country
- swimming
activities that use the phosphagen system
shot-put, sprinting, and jumping
ATP
- adenosine trisphosphate
- body’s energy source (CHO)
- two high-energy bonds
creatine phosphate
the main high-energy, phosphate-storage molecule of muscle
glycogen
form of glucose that is made up of many connected glucose molecules and is stored in the liver and muscles
glucose
the main type of sugar in the blood and is the major source of energy for the body’s cells
lactate (lactic acid)
the waste product produced during anaerobic respiration
What are the three components of the Total Energy Expenditure pie chart?
basal metabolic rate, physical activity, and thermic effect of food
basal metabolic rate
the number of calories you burn as your body performs basic (basal) life-sustaining function
physical activity
any movement of the body that requires energy expenditure
