Endurance Training W3 Flashcards
What is endurance exercise?
Aerobic
Enhances the ability for pro-long period of performance at low/median exercise intensity
What is the hallmark of endurance training?
Increase VO2 Max
What is the aim of endurance training?
Increase aerobic performance
Prevent disease
Cardiorespiratory fitness
What is the biggest metabolic adaptation of endurance training?
Increase the ratio of lipid to carbohydrate usage
Sparring CHO (glycogen)
How does endurance training modify proportion of energy sources?
Muscle Mitochondrial content increases
Fatty acid uptake increases
Rate of glycogen breakdown decreases
Glucose uptake decreases
What happens when muscle mitochondrial content increases?
Enhances the capacity of muscle to synthesize ATP from aerobic breakdown of fat and CHO
What happens when fatty acid uptake increases?
Increased capillary density and lipoprotein lipase in muscle
Facilitate delivery and hydrolysis of TG
What happens when rate of glycogen breakdown decreases?
It reduces the production of AMP and Pi
What happens when glucose uptake decreases?
Decreased in trained people due to increased GLUT4
What is the effect of lactate as a resultant of reduced carbohydrate?
Diminishes lactate production
How does endurance training increase VO2 max?
Increased erythrocytes
Increased stroke volume
What happens when there is an increase in erythrocytes?
Increases haemoglobin
What happens when there is an increase stroke volume?
Increases maximal cardiac output
What is cardiac output?
Maximal blood volume pumps by heart
What is the effect of endurance training on Plasma Lipid Profile?
Increased HDL
Reduced total cholesterol and LDL
Reduced plasma triacylglycerol concentrations
