Adaptations To Aerobic Training Flashcards
Adaptations to respiratory system
Adaptations to respiratory system include
Increased strength of respiratory muscles
Increase SA of alveoli,
increase a-VO2 diff, delivering more 02 to muscle.
Delay OBLA
Increases intensity/duration of performance
Alleviates symptoms of asthma
What is a-VO2 diff
a-VO2 diff is difference between 02 in blood in arterial blood compared to blood in veins. Indication of how much oxygen is removed from capillaries
Adaptations to cardiac system
Adaptations to cardiac system up include
Myocardial hypertrophy, decrease in end systolic volume, , greater elasticity of heart, increased EDV, increased recovery rate.
Increased HR reserve
END systolic volume
ESV is volume of blood left in ventricle after they contract
End diastolic volume
EDV is how much heart fills up with blood.
Bradycardia
Bradycardia is lower resting HR
Adaptations to vascular system
Adaptations to vascular system include
Increased elasticity of arterial walls, improve capacity to vasoconstrict and vasodilate, enhancing efficiency of vascular shunt mechanism
Blood volume will increase due to Increase in plasma (reduce blood viscosity and aids venous return) and RBC (increases 02 carrying capacity)
, increase capillarisation (around lung and muscle tissue increases capacity for gaseous exchange)
Adaptations to muscular system
Adaptations to muscular system are
Hypertrophy of slow twitch muscle fibres, delays OBLA
Increased size and density mitochondria, delays OBLA
More glycogen stores in muscle, delays OBLA
Increased myoglobin stores, delays OBLA
How does aerobic training help health
Aerobic training increases lactate threshold, delay OBLA, (hit OBLA at a higher % of VO2 max)
Increase aerobic metabolism
Increase VO2 max
Adaptations of aerobic training on connective tissue
Adaptations of aerobic training on connective tissue are
Increase in strength of connective tissue
Increased calcium deposits on bone
What do stronger respiratory muscles do and what does greater SA of alveoli do
Stronger respiratory muscles increase
Maximal lung volumes (increased breathing frequency and tidal volumes)
Greater SA of alveoli increases external gaseous exchange
Benefits of aerobic training to respiratory system
Benefits of aerobic training to respiratory system are
Delay OBLA
Increase intensity/duration of performance
Alleviates symptoms of asthma
Stronger respiratory muscles
Greater SA of alveoli helps gaseous exchange
