• increased left ventricle

• increased maximal cardiact output
  
  

aerobic repiratory chronic adaptations

• increased maximal ventilation

• increased tidal volume

• decreased resting respiratory rate

• increased pulmonary diffusion

blood chronic adapations

• decreased blood pressure

• increased heamoglobin

blood vesels chronic adaptations

increased capilrisation at heart and muscles

muscular aeorbic chronic adapations

• increased enzyme activity

• increased oxidative enzymes

• increased glycogen stores

• increased AVO2 diff

• increased mitochondiral density

• increased fat oxidation

muscular anaerobic adapations

• hypertrophy

• increased ATPase

• increased glycogen stores

• increased glycolitic enzymes

• increased CP stores

neuromuscular anaeorbic adaptations

• increased motor unit recuritment

• increased motor unit cooridination

• increased motor unit firing frequency

increased motor unit firing frequecny

when training anaerobically summation of your impulses increases helping your abillity to recruit motor units increasing your force output when contracting

increased motor unit coordnation

increased ability to coordinate the activation of greater motor units at the same time increasing motor unit recuriment and thus a greater force output

increased motor unit recuritment

training makes you used more motor units when training and this will increase your force output as you contract with the force of more muscle fibres

increased ATPase

allows you to break down energy quickly increasing the speed of contraction

Hypertrophy

increase in the size of your muscle fibres (mainly type 2) allowing for greater force output when you contract

increased glycoltic enzymes

greater enzymes to speed up ATP production with glycogen increased the rate of energy production thus speed of contraction

increases in glycogen and PC stores

greater stores to produce more ATP anaerobically increasing the rate of ATP production thus increasing speed of contraction and duration working anaerobically

increased fat oxidation

increases your ability to use fats as fuel source as you helping you preserve glycogen for later

increased glycogen stores

more muscle glycogen stores giving you more abillity to produce ATP via the prefered fuel source allows your to use more aerobically and increasing aerobic intensity

increased AVO2 diff

more blood in the arteries compared to the veins means that the muscles are extracting more oxygen increasing your abillity to work at a high intesnity aeorbically

increased oxidative enzymes

breaks down fuel sources faster with oxygen increase the amount of aerobic ATP giving you an abillity to work at a higher intesnity aerobically

increased myoglobin

more myoglobin (oxygen in muscles) allows you to produce more ATP aerobically allowing you to work at a higher intensity aerobically

increased mitochondrial denisty

allows you to produce more ATP with oxygen therfore you can work at a higher intesnity aerobically

decreased blood pressure during rest

your blood veseles become more elastic and your stroke volume increases doesnt really improve performance

increased blood volumes (more red blood cells, plasma and heamoglobin)

blood is easier to pump as it thinner increasing supply of oxygen ad well as greater ability to supply

increasd muscle capillirisation

increased amount and size of capillaires allowing more gas exchange to occur increasing the abillty to supply oxygen

increased heart capilrisation

increases in the amount of capillaries at the heart increasing the abillty to supply oxygen and produce ATP aerobically

decrease resting heart rate

as stroke volume increases you do not need to pump out more blood as your stroke volume

increased maximum cardiac output

you pump out more blood per minute due to havign a greater stroke volume increasing supply of oxygen thus abillity to produce ATP aerobically

increased stroke volume

you are able to pump more blood per beat due to left ventricle being bigger increasing your abillity to supply oxygen and produce ATP aerobically

increased maximal ventilation

you are able to take in more air per minute becuasen your tidal volume has increased increasing your oxygen uptake and supply to working muscles

increased tidal volume

you can breath in more air per breath increasing oxygen uptake thus helping supply more oxygen to working muscles

decreased respiratory rate

as your breath in more air per breath you need elss breaths at rest to supply oxygen this leads to a lower rate of fatigue as it give more oxygen for exercise

increased pulmonary diffusion

your speed of gas exchange is quicker allowng you to supply more oxygen to the working muscles and produce ATP aerobically

increased aveloi surface area

the size of your alveoli increases allowing you to increase and speed up gas exchange thus increasign your abillity to supply oxygen
