In 4 equal groups, each group will be assigned a system to research. You need to make sure your group researches your particular area thoroughly and covers the following responses depending on what system has been assigned. Your group will then present back the findings to the rest of the group through a detailed and informative A3 poster.
• Musculoskeletal response: increased blood supply; increase in muscle pliability; increased range of movement; muscle fibre micro tears
• Energy systems: phosphocreatine; lactic acid; aerobic; energy continuum; energy requirements of different sport and exercise activities
• Cardiovascular response: heart rate anticipatory response; activity response; increased blood pressure; vasoconstriction; vasodilation
• Respiratory response: increase in breathing rate (neural and chemical control); increased tidal volume.

The short term effects on MUSCLES/
JOINTS and
BONES
Musculoskeletal response: increased blood supply; increase in muscle pliability; increased range of movement; muscle fibre micro tears
Short term effects of & responses to exercise – Bones & Joints.
• We produce more synovial fluid
– Movement stimulates the secretion of synovial fluid.
• The joints become warmer
– Exercise increases the bodies temperature
– The synovial fluid becomes thinner, making movement more efficient.
• The range of movement increases
– Due to the fact that the synovial fluid is thinner and warmer • All of this is because exercise makes our joints move quickly, so there needs to be more synovial fluid in the joints to allow and assist this movement
When we start to warm up:
• The muscles need energy in the form of glycogen to make the sarcomeres contract.
– So the heart (cardiac muscle) beats faster to provide the glycogen to the muscles via the blood.
• The conversion of chemical energy (from the
Glycogen) to movement (contraction of the
