Effects of Exercise - Responses and Adapations of the Body Systems

OVERVIEW

What students need to learn:

Muscular-skeletal system:

  • Responses (fibre recruitment, force production, metabolism)
  • Adaptations (increase fibre size, increase force production, increase metabolic energy supply)

Cardiovascular:

  • Responses (increase stroke volume, heart rate, cardiac output, redistribution of blood flow to working muscle)
  • Adaptations (increase in size of heart, stroke volume, cardiac output and number of capillaries)

Respiratory:

  • Responses (increased rate and depth of breathing, increased gas exchange)
  • Adaptations (improvements in respiratory muscle performance)

Neuro-muscular:

  • Responses (increased number of muscle fibres recruited, increase in rate of fibre recruitment)
  • Adaptations (improved coordination, increases in force production and rate of force production, increase in speed)
