Card preview (15)
How many months of training do chronic adaptations occur from and what are these changes?
2-3 months of training, they are long term physiological changes in response to increased demands placed on the body through training
What are chronic adaptations specific to and where do they occur in the body?
Specific to the type of training you do, occur in cardiovascular, respiratory or muscular systems
What do cardiovascular adaptations all increase?
The delivery of blood and therefore oxygen to the working muscles
Which part of the cardiovascular system is cardio and which part is vascular?
The heart is the cardio part and the blood vessels are the vascular part
What are some examples of cardio chronic adaptations?
Increase in left ventricle size, cardiac output and stroke volume
What are some examples of vascular chronic adaptations?
Increase in capillary density, blood flow to working muscles, blood volume and haemoglobin
What do respiratory chronic adaptations all increase?
The amount of oxygen breathed in and diffused into the bloodstream
What are some examples of respiratory chronic adaptations?
Increase in lung capacity, tidal volume, decrease in rest and sub-maximal ventilation
To what will aerobic training bring about the most specific and significant adaptations?
Slow twitch fibres
What do muscular chronic adaptations all increase?
The use of oxygen to resynthesize ATP by the aerobic system
What are some examples of muscular chronic adaptations?
Increase of myoglobin content, capillary density, mitochondria size, number and surface area
What do all aerobic chronic adaptations assist with?
Increasing lactate inflection point
What is the meaning of systolic function?
When blood is pumped out of the heart with more force during exercise
What is hypertrophy?
An increase in fast-twitch fibre size
What does hypertrophy lead to?
An increased size and number of myofibrils and increased size and strength of connective tissues such as tendons and ligaments
