Mocks Flashcards
Carbohydrates
60 % of diet. Macronutrient Helps with endurance Simple- broken down quickly and used as energy. Complex- stored as starch
Fats
20% of diet
Macronutrient
Slows down absorption of carbohydrates and prolongs energy store.
Protein
20% of diet
Macronutrient
Helps regrow and repair muscles
What does dehydration cause?
- Blood thickening which slows blood flow around the body.
- Increased/irregular heart rate.
- Increased body temp.
- Slower reaction time.
- Increase muscle cramps/fatigue
Voluntary muscle
Muscles with conscious control
Involuntary muscles
Muscles with no conscious control
Tachycardia
Heart rate too quick over 100bpm
Bradycardia
Heart rate too slow under 60bpm
Aerobic respiration equation
Glucose + Oxygen - Carbon dioxide + water
Anaerobic respiration
Glucose - Lactic acid + energy
EPOC
During exercise breathing frequency and depth increases and during oxygen debt Lactic acid and other waste products are removed as oxygen supply is replenished.
Warm up
- Increase Cardiac and respiratory rates.
- Stretching / mobility
- Skill familiarisation
- Mental preparation
A warm increased muscle temperature and reduces muscle viscosity as well as increasing range of movement at joints
Cool down
Gradually reduces cardiac and respiratory rates and Stretching for flexibility training
Stretching
Helps remove waste products like Lactic acid
Rehydration
Speed up glycogen replacement
Ice baths
Cold water causes blood vessels to vasoconstrict and drain blood out of legs as well as waste products that has built up from activity
Vo2 Max
Maximum rate of the body processing oxygen effectively. Test Cardiovascular endurance
1st class lever example
Neck joint for high jump or heading a football
2nd class lever example
Ankle joint for jumping or running
Alveoli adaptions for gaseous exchange
- Large blood supply to carry gases.
- One cell thick for short difussion distance
- Lots of capillaries meaning a large area for gaseous exchange to occur.
