Week 1 an 2 Skeletal and Muscular System
• Identify the muscles and bones in the body
• Outline the functions of the skeletal and muscular system
Bones that are responsible for protection are in the Axial Skeletons (Chest, Neck,
Head, Back). Other bones aid in movement (Appendicular)
Muscles move by contracting and extending.
• Distinguish between the axial and appendicular skeleton
Axial is the bones in the Head, back, chest, and neck
Appendicular is everything else
• Compare and contrast the types of bones
•
• Apply the correct anatomical terminology
, • Outline the function of muscles
1. Movement - when skeletal muscles contract, they exert forces on tendons which
pull on bones causing movement
2. Moving substances within the body - smooth muscles help move food through the
gastrointestinal tract.
3. Maintaining posture - when postural muscles contract they help to stabilize and
maintain body positions.
4. Generating heat - when muscles either involuntarily/ voluntarily contract they can
generate up to (supposedly) 85% of body heat
• Distinguish between the types of muscles
5. Skeletal
6. Cardiac
7. Smooth
• Outline the general characteristics of common muscle tissue
All muscles are controlled by nerve stimuli and fed by capillaries.
• Explain how muscles work in antagonistic pairs
Muscles work in antagonistic pairs as they can only exert a pulling force, and can't push
themselves back to their original position. This means each pair has 'opposite' muscles (in
order to 'pull' each other back) and an example of this is the bicep and tricep
• Identify antagonistic pairs
Week 3 and 4 Biomechanics
• Define biomechanics
The study of the mechanical laws relating to the movement or structure of living
organisms.
• Explain what factors impacts stability and apply to sporting scenarios
Centre of mass is a crucial part of many sports, being something that can be
manipulated in order to reach a goal. For example, in high jump the Fosbury Flop
took advantage of the arching of ones back, which separated the centre of mass
from the body, raising the high jump ceiling.
Centre of mass is used for stability in a variety of sports, more traditionally in a
protection role. To maximise stability, lowering this point (centre of mass) by
widening the base (typically the legs) is done.
• Identify the position of a bodies centre of mass in numerous sporting contexts
A relatively simple way of tracking centre of mass is drawing a box, then an x within
that box to find the centre of mass. This applies to the contortion of the body no
matter what.
• Explain how gravity impacts a projectile
