Paper 1 Flashcards
Bones @ elbow
- humerus
- radius
- ulna
What is a isotonic contraction
Eccentric - muscle lengthens , bicep curl ( downward phase ) , press up (downward phase)
Concentric - muscle shortens , bicep curl ( upward phase )
What is a isometric muscle contraction
No movement , plank
What is the Pathway of blood
Vena cava > right atrium > right ventricle > pulmory artery (lungs) > pulmonary vein > left atrium > left ventricle > aorta
What is cardiac output and it’s equation
Volume of blood per minute
Stroke volume x heart rate
What is stroke volume
Volume of blood ejected per beat
What is heart rate
Number of beats per min
What’s the restitubtion of blood during exercise
Vasoconstriction- narrowing of arteries, less blood to muscles
Vasodilation- opening of arteries , more blood to muscles
What is abduction
Movement of limb towards the midline of the body
What is adduction
Movement of a limb away from the midline of the body

Example of a first class lever
Press up
Example of a 2nd class lever
Calf raise
Example of a 3rd class lever
Bicep curl
Explain high altitude training
- 2000m above sea level
- cardio vascular endurance
- more blood cells = less oxygen
Explain flexibility
- range of movement possible at the joint
- gymnastics
- complex skills = higher marks
