Aerobic respiration is when
Is when the body uses oxygen to break down glucose to release energy, for a long duration and a low to moderate intensity.
Equation for aerobic respiration
Aerobic (glucose + oxygen → carbon dioxide + water)
Anaerobic respiration is when
Is when there’s not enough oxygen available, so the body breaks down glucose without oxygen. This for a short duration and a high intensity.
Equation for anaerobic respiration
Anaerobic (glucose → lactic acid)
Define EPOC
Excess Post-exercise Oxygen Consumption, also known as oxygen debt
What is the reason of EPOC
Caused by anaerobic exercise
What is produced during EPOC
Lactic acid and requires high breathing rate after exercise to remove it
Factors affecting recovery time (5)
Fitness level
Intensity of exercise
Duration of exercise
Type of exercise
Rest and sleep
Short- term effects of exercise (5)
Heart rate increases
Breathing rate increases
Sweating
Fatigue
Suffering of nausea
Long-term effects of exercise (4)
Heart size
Resting pulse rate
Stroke volume
Ability to tolerate lactic acid
What is force
A pull or a push
Equation of force
force = mass × acceleration
Types of forces exerted during exercise (5)
gravity
air resistance
muscular force
ground reaction force
force applied at release
Applications of force (3)
A moving performer
A sprinter in the blocks
An object flying through the air
Equation for levers
FRE-the middle letter of each lever
What does FRE stands for
F:ulcrum-The pivot point where the lever rotates.
R:esistance-The load or weight to be moved.
E:Effort-The force applied to move the resistance.
First class lever
Effort ↔ Fulcrum ↔ Resistance (E-F-R)
Example: Neck during head movement.
Second class lever
Fulcrum ↔ Resistance ↔ Effort (F-R-E)
Example: Calf raise.
Third class lever
Fulcrum ↔ Effort ↔ Resistance (F-E-R)
Example: Bicep curl
