- 1What is anaerobic respiration?High intensity lasting up to 60 seconds. Your body breaks down glucose to create energy without oxygen.
- 2What is the equation for anaerobic respirationGlucose ---> energy + lactic acid
- 3What is lactic acid?A poison that can cause pain and reduce muscle contractions
- 4What is oxygen debt?The amount of oxygen needed to break down the lactic acid in muscles after vigorous exercise
- 5How do you recover from anaerobic respiration?1) Breathing to reduce oxygen debt
2) Perspiration to cool and remove water
3) Excretion to remove water and waste - 6What is fatigue?Extreme tiredness caused by lack of muscle glycogen
- 7What is stress?Physical, mental or emotional adjustment to change
- 8What impacts do fatigue have on the body?~ Muscles cant contract
~ Concentration decreases
~ Movement is less fluent - 9How do performers respond to stress?Get psyched up (determined)
Aggression
Tension (tightness in muscles)
Anxiety
Drop in motivation - 10What makes up the circulatory system?Blood and blood vessels
- 11What are the functions of the circulatory system?TRANSPORT: oxygen to muscles / CO2 to lungs / waste products to kidneys
PROTECTION: White blood cells / Platelets form clots to stop bleeding
TEMP CONTROL: maintain and controls - 12What are the two types of temperature control in the circulatory system?Vasoconstriction ~ maintains heat
Vasodilation ~ cools the body - 13What is the cardiovascular system?The circulatory and respiratory system working in unison.
Heart and Blood vessels - 14What is cardiovascular endurance?The ability of the heart to provide oxygen to the muscles for long periods of exercise.
- 15What are the different training zones? (%)Max heart rate ~ 220-age
Anaerobic zone ~ 80-90% of max heart rate
Aerobic zone ~ 60-80% of max heart rate - 16What is recovery rate?The time it takes for the heart rate to return to resting
- 17What is aerobic respiration?Low intensity activity for a long period of time
- 18What is the equation for aerobic respiration?Glucose + oxygen ---> energy + CO2 + water
- 19Where does gaseous exchange take place?Between alveoli and capillaries
- 20What happens in gaseous exchange?High pressures of oxygen diffuse into the blood in capillary.
High pressures of CO2 diffuse from capillary into the alveoli.
They do this to balance pressure. - 21What are the two types of injury?Internally caused --> Where the performer is solely responsible.
Externally caused --> Environmental factors are responsible such as conditions or opponents. - 22What are the three causes of internally caused injury?Incorrect technique
Overuse
Sudden movements - 23What are the three causes of externally caused injury?Foul Play
Impact
Equipment / Clothing
