factors affecting VO2 max

• Define VO2 max


  Maximum volume of oxygen utilised by muscles per minute
• What's vo2 max measured in

  ML/KG/MIN , so takes into account body weight
• What is vo2 max a measure of

  Aerobic fitness ( stamina/endurance )
• Explain what a higher V02 means

  • higher VO2 max, higher the aerobic power
  • higher VO2 max means that more oxygen is supplied to muscles
  • means performer able to work at higher intensities for longer periods, as delay in lactic acid build up ( obla )
  • performer with high VO2 max can also recover quicker after anaerobic work due to inc oxygen during lower intensity periods of play, allowing more frequent sprints
• How are VO2 levels determined

  VO2 max levels are genetically determined which limits impact of training
• List factors affecting VO2 max

  • physiological factors
  • lifestyle
  • genetics
  • training
  • age
  • body composition
  • gender
• Explain how physiological factors affect VO2 max

  • ( increased stroke volume, myoglobin and inc capillarisation )these physiological factors all increases VO2 maxallowing more oxygen to be delivered to muscles
• Explain how lifestyle affects VO2 max

  • ( smoking , lack of exercise )poor lifestyle factors greatly reduce VO2 max, trained performers are likely to make positive lifestyle choices
• Explain how genetics affect VO2 max

  • inherited factors of physiology limit possible improvement, elite aerobic performers likely born with good genetics
• Explain how training ( aerobic ) affects VO2 max

  • improves VO2 max by 10-20%, elite endurance athletes carry out high levels of continuous training
• Explain how age affects VO2 max

  VO2 max decreases with age, elite performers relatively young
• Explain how body composition affects VO2 max

  • a higher percentage of body fat decreases VO2 max, that's why elite performers have low percentage of body fat
• Explain how gender affects VO2 max

   men generally have approx 20% higher VO2 max than females
