Slide 1: 

Ogmore School Mr M Humphreys Unit 1: The Body in Action. Assignment 3. The effects of exercise on the skeletal and muscular system. SHORT TERM EFFECTS OF EXERCISE ON SKELETAL SYSTEM. Secretion of synovial fluid. Synovial fluid becomes less viscous. Range of movement can increase.

Slide 2: 

Ogmore School Mr M Humphreys LONG TERM EFFECTS OF EXERCISE ON SKELETAL SYSTEM. Increases bone density. Increases or maintains full range of movement. Increases supply of synovial fluid. As exercise imposes stress upon the tissue of the skeletal system then in turn these tissues will become stronger. The hyaline cartilage at the end of bones will become thicker and become better at shock absorption. Tendons will become thicker and able to withstand greater force Ligaments will stretch slightly to enable greater flexibility at the joint.

Slide 3: 

Ogmore School Mr M Humphreys SHORT TERM EFFECTS OF EXERCISE ON MUSCULAR SYSTEM. Become warmer. Become more pliable. Demand more oxygen. Greater blood supply through capillary dilation. Increased metabolic activity.

Slide 4: 

Ogmore School Mr M Humphreys LONG TERM EFFECTS OF EXERCISE ON MUSCULAR SYSTEM. Improved range of movement through a joint. Lengthening of the muscle stretched. Improved muscular strength and endurance. Improved muscle tone and posture.

Slide 5: 

Ogmore School Mr M Humphreys PHYSIOLOGIOCAL EFFECTS ON SKELETAL MUSCLE INCREASE IN TEMPERATURE IN THE MUSCLES AFFECTS THE SPEED AND STRENGTHOF THE CONTRACTION Greater elasticity of fibres improves the force and contraction of the movement

Slide 6: 

Ogmore School Mr M Humphreys Increase in muscle temperature increases the speed of contraction and relaxation of the muscle Increase in speed of nerve transmission cause increases in muscular contraction. Increase in enzyme activity as the muscles get warmer This increase the strength and speed of muscular contractions Glucose ATP ENZYME ATPase

Slide 7: 

Ogmore School Mr M Humphreys Increase in blood and O2 to the muscles which reduces the risk of injury. Bundle of fibres Individual muscle fibre Muscle
