Chronic Adaptions of Training and Psychological Strategies Flashcards
what is the purpose of training?
to make an athlete ‘fitter’
what occurring as a result of training leads to improved fitness and performance?
chronic adaptions
how does a training program cause the body to adapt?
puts physical stress on the body forcing it to adapt
what are the two types of adaptions that can occur?
structural and functional
what chronic adaption occurs at the lungs?
increased lung volume
what does the adaption of increased lung volume also increase as a result?
diffusion, efficiency and oxygen consumption
what is a chronic adaption that occurs at the heart?
increased heart size and volume
what occurs as a result of the body adapting and the heart increasing in size and volume?
- lower resting heart rate
- higher stroke volume
what chronic adaption occurs at the stomach?
decreased blood flow to other organs eg. digestive system
what chronic changes increase at the muscle?
- capillarisation of slow twitch fibres
- a-VO2 DIFF
- muscular fuel stores and enzymes
what occurs due to increased capillarisation of the slow twitch fibres at the muscle?
increased fibre size
what chronic adaptions occur in the blood?
- increased blood volume
- decreased rate of lactate production
what occurs as a result of increased blood volume?
increased plasma and haemoglobin
what adaptions occur as a result of aerobic training?
- cardiovascular
- respiratory
- muscular
what adaptions occur as a result of anaerobic training?
- cardiovascular
- muscular
what adaptions occur as a result of resistance training?
muscular
where can changes occur in the cardiovascular system as a result of aerobic training?
- heart
- blood vessels (veins, arteries, capillaries)
- blood
what do all the changes to the cardiovascular system as a result of aerobic changes contribute to?
delivering more oxygen to the working muscles
what adaptions occur at the heart as a result of aerobic training?
increased: -mass and size of left ventricle -stroke volume -cardiac output -efficiency of heart decreased: -HR during submax activities -resting HR
what is the equation to determine cardiac output?
Q=SV x HR
what is the name for a decreased resting heart rate?
bradycardia
what adaptions occur at the blood vessels as a result of aerobic training?
increased:
- size of coronary arteries and capillaries
- no.of capillaries
- at rest and submax activity blood flow to working muscles decreases slightly
- during maximal and high intensity blood flow to the working muscles increases
why does blood flow to the working muscles during rest and submax activity decrease slightly due to adaptions to the blood vessels?
due to increased ability to deliver, extract and use oxygen
why does blood flow to the working muscles during maximal and high intensity activity increase due to adaptions to the blood vessels?
due to increases in cardiac output, redistribution of blood flow and increases in capillarisation at the muscles
what what muscle fibre is the size of coronary arteries and capillaries increase as a result of aerobic training?
slow twitch fibres
how does an increase in size of coronary arteries and capillaries result in as an adaption of aerobic training?
increases supply of oxygen and waste removal
what molecule extracts oxygen?
myoglobin
what molecule carries oxygen through the bloodstream?
haemoglobin
what adaptions occur in the blood as a result if aerobic training?
increases in:
- volume of plasma and red blood cells
- a-VO2 DIFF
- higher LIP
what does a higher volume of plasma due to aerobic training result in?
Increased plasma helps increase stroke volume and also removes heat more efficiently
what does a higher volume of red blood cells due to aerobic training result in?
increased red blood cells means there is more haemoglobin therefore more oxygen transported through blood to working muscles
what does a higher a-VO2 DIFF due to aerobic training result in?
increased oxygen extracted by the muscles
what are the structural respiratory adaptions due to aerobic training?
increased:
- lung volume
- diffusion
what does increased diffusion due to respiratory adaptions of aerobic training result in?
due to larger lung volume, more alveoli, capillary interfaces for diffusion to occur
what is the equation for VO2MAX?
VO2MAX= SV x HR x a-VO2 DIFF
what is the equation for ventilation?
Ve= TV x RR
what is respiratory rate?
number of breaths per min
what is heart rate?
number of heart beats per min
what is stroke volume?
the amount of blood pumped out of the left ventricle each beat
what is tidal volume?
the amount of air exhaled per breath
what are the functional respiratory adaptions due to aerobic training?
- ventilation decreases slightly at submax intensity
- TV increases
- ventilation at max intensities increases
- ventilation efficiency increases
- VO2MAX increases
why does ventilation increase during maximal intensity activity as a result of aerobic training?
due to increases in tidal volume and respiratory rate
why does ventilation efficiency increase as a result of aerobic training?
muscles responsible for breathing require less oxygen to work therefore they demand less energy leaving more to be delivered to the working muscles
what muscles are responsible for breathing?
diaphragm and intercostals
what is an increased VO2MAX the result of?
increased oxygen delivery and ability for the muscles to extract oxygen from the blood
where is ATP produced?
in the mitochondria
what main structure and functions does muscular adaptions impact as a result of aerobic training?
- muscular structure
- mitochondria
- myoglobin
- oxidation of fats/ glycogen
what muscular adaptions occur to the muscular structure as a result of aerobic training?
- increased aerobic capacity of slow twitch fibres
- fast twitch fibres take on characteristics of slow twitch fibres
- increased hypertrophy of slow twitch fibres due to increased capillary density
what muscular adaptions occur to the mitochondria as a result of aerobic training?
increases:
- size, number and surface area
- oxidative enzymes
what does and increase in oxidative enzymes at the mitochondria as a result of muscular adaptions due to aerobic training result in?
speeding up rate of ATP produced aerobically
what does an increase in myoglobin due to muscular adaptions from aerobic training result in?
increased myoglobin in slow twitch fibres. Extracting haemoglobin from the bloodstream therefore resulting in a higher a-VO2 DIFF
what does an increase in the oxidation of fats due to muscular adaptions from aerobic training result in?
increased ability to use free fatty acids as a fuel source. Beneficial to endurance athletes as it allows them to conserve glycogen stores (glycogen sparing)
what does an increase in the oxidation of glycogen due to muscular adaptions from aerobic training result in?
endurance training also enhances body’s ability to breakdown glycogen at high or maximal intensities
what cardiovascular adaption occurs as a result of anaerobic training?
increased wall thickness of the left ventricle
what does an increased wall thickness of the left ventricle result in?
heart can eject more blood, more forcefully with each beat
is there an increase in left ventricle size with anaerobic training?
no
is there an increase in left ventricle size with aerobic training?
yes
is there an increase in stroke volume with anaerobic training?
no
what muscular adaption occurs as a result of anaerobic training?

- ATPase
- tolerance to metabolic by products
what is the significance of increased ATP and PC stores in fast twitch fibres as a result of anaerobic training?
