chronic adaptations from hiit

• chronic adaptations from hiit

  • improves exercise capacity and performance (faster time trials or longer time to exhaustion) for aerobic activities
  • hiit has less time commitment but can achieve similar health benefits
  • mechanism of benefit is related to the greater energy expenditure following the exercise session due to the longer and more extensiv recovery period
  • hiit improves aerobic fitness
• cardiovascular hiit chronic adaptations

  • increase capillarisation
  • decrease systolic and diastolic blood pressure
  • increase arterio-venous oxygen difference (a-VO2 difference)
  • increase stroke volyme
  • increase max. cardiac output
  • increase blood volume
  • decrease resting and submax. HR
• muscular hiit chronic adaptations

  • increase VO2 max. (respiratory)
  • increase mitochondrial mass
  • increase muscle oxidative capacity
  • increase muscle buffering capacity
  • incease resting muscle glycogen content
  • increase rate of glycogen use
  • decrease lactate production
  • increase lactate tolerance
  • decrease reliance on carbohydrates as a fuel source during exercise
