Muscular skeletal system WHOLE UNIT

This bundle contains all sub unit sections of the Edexcel A-level PE specification for unit 1; Muscular skeletal system. These resource notes are A grade.
1.1.2 The stretch-shortening cycle, including the different types of
contraction/muscular action: isotonic/eccentric,
isotonic/concentric and isometric. Application of how movement
or stability is produced as a result of these different
contractions/muscular actions during physical activity and
sporting movements.
1.1.3 The concept of agonist, prime mover, antagonist, fixator,
synergist and how a muscle can take on these different roles
when providing stability or movement in a variety of physical or
sporting situations.
1.1.4 The components of an anatomical lever and how the body uses
the lever systems (1st, 2nd and 3rd class) in physical activity
and sport. This should include the mechanical advantages and
disadvantages of each lever.
1.1.5 Newton’s Three Laws of Motion and how they apply to sporting
contexts: Law of Inertia, Law of Acceleration and Law of Action
and Reaction.
1.1.6 The principles related to the stability of the body in relation to
the centre of mass and its implication in physical activities.
1.1.7 The calculation of force and resultant force: a mass of 1 kg
exerts a force of 9.81 N (down).
1.1.8 How the muscular and skeletal systems respond, acutely, both
structurally and functionally to the stress of warming up and
immediate physical or sporting activity
