Muscular System 1 of 13 The contracting and lenthening of muscles Movement 2 of 13 These help to define body shape and maintain posture Muscles 3 of 13 These bring about movement and can be consciously controlled and trained to become stronger Voluntary Muscles 4 of 13 Muscles are attached to the skeleton by these tendons 5 of 13 Each muscle is made up of these and when they contract or pull against the skeleton and movement takes place Muscle Fibres 6 of 13 Muscles are arranged like this so that when one contracts, the other one relaxes Antagonistic Pairs 7 of 13 These are muscle contractions which result in increased tension but the muscles length stays the same Isometric Contractions 8 of 13 These contractions result in limb movement Isotonic Contractions 9 of 13 When using progressive overload, the muscle becomes torn. It then rebuilds itself making it slightly stronger and the muscle mass is increased Hypertrophy 10 of 13 Muscle hypertrophy can lead to an increase in this and can also lead to an increase in power Muscular Strength 11 of 13 Strength x speed Power 12 of 13 An increase in this will mean that muscles will be able to withstand more as they are progressively overloaded Muscular Endurance 13 of 13
