Sports & Nutrition Flashcards
Respiration
glucose + oxygen -> water + carbon dioxide + ATP
Aerobic vs Anaerobic
Aerobic is with air, while anaerobic is without air
Examples of aerobic & anaerobic
Aerobic- Walking, Golf & Archery
Anaerobic- Running, Swimming & Weightlifting
Aerobic equation
oxygen + glucose -> water & carbon dioxide
Anaerobic respiration
glucose -> lactic acid+ less energy
Circulatory system
Heart, Blood vessels & Lungs
Chambers of the heart
Left & Right atrium
Left & Right Ventricle
Formation
Atrium is on the top, ventricle on the bottom. Left & Right swapped because the way the heart is
Side of blood
Blood on the right is deoxygenated. Blood on the left is oxygenated
Arteries, veins & capillaries
Arteries- Elastic fibers and thick muscular walls
Veins- Thin muscular walls and less elastic fibers
Capillaries- 1 cell thick = short diffusion.
Control groups
The group that doesn’t have the independent variable used but everything else is the same
Reliability
Getting the same results multiple times
Validity
Fair test. All variables are constant except dv and iv
Accuracy
Correct equipment to get closest to the correct value
Precision
Measuring things in smaller intervals
Lung contents on left
Bronchi, Intercostal muscles
Lung contents on right
Ribs, Bronchiole, Alveoli, Lung & Diaphragm
Lung contents in the middle
Trachea
Gaseous exchange
Oxygen comes in the alveoli and carbon dioxide leaves the alveoli
Nicotine, Tar & Carbon monoxide
Nicotine- Addictive drug which affects central nervous system
Tar- Brown, sticky substance and coats the surface of the alveoli
Carbon monoxide- Poisonous gas which bonds to hemoglobin, which decreases the amount of oxygen going around your body
5 food groups
Fruit and vegetables, carbohydrates, protein, fat food, milk and dairy foods
PED
Any substance that improves a person/athletes performance
Anabolic steriod
Makes you stronger because the cells divide and grow
