Adaptations To Aerobic Training 2 Flashcards
What is myocardial hypertrophy and why is useful
Myocardial hypertrophy is when muscle wall of left ventricle thickens.
Useful because increases resting and maximal SV and increased maximal Q because of increased ventricular stretch and force of ventricular contraction.
Decreases resting Hr (bradycardia)
What is effect of increased elasticity of arterial walls
Effect of increased elasticity of arterial walls are
Increased vascular shunt efficiency because of
Improved capacity of vasoconstriction and vasodilation
Decreased resting B0 and increased BP regulation
What is effect of increased blood/plasma volume
Effect of increased blood/plasma volume are
Reduced blood viscosity, increased venous return and SV
What is effect of increased RBCS and haemoglobin
Effect of increased RBC and haemoglobin include increased 02 carrying capacity and increased gaseous exchange.
What are effects of capillarisation around alveoli and type 1 muscle fibres
Effect of Capillarisation (capillaries grow in greater density and thickness) are increased surface area for blood flow.
Increased gaseous exchange
Decreased distance for diffusion.
Increased diffusion more 02 enters, more C02 leaves, removal of LA
Benefits of aerobic training to cardiovascular system
Benefits of aerobic training to cardiovascular system are
Increased blood flow,02 transport and decreased blood pressure.
Delays OBLA
Increases intensity/duration of performance
Lowers risk of coronary heart disease, hypertension and stroke.
What are the effects of increased size and density of mitochondria
Effects of increased size and density of mitochondria are
More aerobic respiration
Delay OBLA
What is myoglobin and what are effects of increased myoglobin stores
Myoglobin is storage point of 02 in muscle.
Effects of increased myoglobin stores are increased transport of 02 to mitochondria and delays OBLA
Benefits of aerobic exercise to muscular system
Benefits of aerobic exercise to muscular system are increased muscle hypertrophy of SO and FOG fibres
Increased size and density of mitochondria, delays OBLA
Increased store of myoglobin, delays OBLA
Increased stores of glycogen delays OBLA
