Assessment Criteria for Unit 2 Physiology of fitness

P1/ 2 M1- Know the acute effects (single bout) of exercise on the body

systems

P1 and P2: Both on the same document. Looking to create an information leaflet/ brochure for each body system, in order to describe how SHORT TERM exercise affects each system. With Merit you have to do wider research and use sporting examples to support your information.

Musculoskeletal response: increased blood supply; increase in muscle pliability; increased range of movement; muscle fibre micro tearsEnergy 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; vasodilationRespiratory response: increase in breathing rate

(neural and chemical control); increased tidal volume.

P3/4 M2- Know the Long term effects of exercise on the body

systems

P3 and P4: Again both on the same document, creating again an information leaflet/ brochure to describe the LONG TERM affects exercise has on the body systems. In order to gain MERIT there has to be evidence of wider reading and annotations to support your work. Using sporting examples is key for MERIT standard work.

• Cardiovascular system: cardiac hypertrophy; increase in stroke volume; increase in cardiac output, decrease in resting heart rate; capillarisation; increase in blood volume; reduction in resting blood pressure; decreased recovery time; increased aerobic fitness

• Muscular system: hypertrophy; increase in tendon strength; increase in myoglobin stores; increased number of mitochondria; increased storage of glycogen and fat; increased muscle strength; increased tolerance to lactic acid

• Skeletal system: increase in bone calcium stores; increased stretch in ligaments; increased thickness of hyaline cartilage; increased production of synovial fluid

• Respiratory system: increased vital capacity; increase in minute ventilation; increased strength of respiratory muscles; increase in oxygen diffusion rate

• Energy systems: increased aerobic and anaerobic enzymes; increased use of fats as an energy source
