a capillary is our body's smallest form of blood vessel
the more capillary's at the muscles, the more oxygen the muscles can use
an increase in capillarisation means that there is an increase in blood vessels and subsequently an increase in the opportunity for blood (and oxygen) to be transported to and used by the muscles
a decrease in capillarisation means that there is a decrease in poo vessels and subsequently a decrease in the opportunity for blood (and oxygen) to be transported to and used by the muscles
aerobic or endurance training does well to bring about an increase in capillarisation, meaning that muscles can perform for longer peroids of time as they are able to use more oxygen for contraction

Can effective long term aerobic exercise lead to increased capillarisation?
If your cat ate some chicken then yeah it's possible
What is a common effect of hypertension on stroke volume?
There are a number of long term effects on stroke volume. These may include reduction in blood pressure and capillarisation among others.
What are chronic adaptations to aerobic exerc ise?
Muscular · Muscle mass increases · Stores of ATP and PC return faster. · No. of and size of Mitochondria. · Glycogen sparing. · Triglyceride stores increase. · Slow twitch fibres may grow slightly. Cardiovascular · Left Ventricle grows bigger · Stroke volume increases · Resting heart rate decreases · Cardiac output will increase at max effort. · More red blood cells in blood · More haemoglobin · More capillaries on heart and skeletal muscles · Veins/arteries dilate in size. · Capillarisation around heart · Arteriovenous oxygen difference increases. · Increase in O2 diffusing into lungs Respiratory · Tidal volume increases · Respiratory rate decreases at rest · Minute ventilation increases for max efforts · Require less oxygen at sub-maximal efforts.
What increases as you exercise?
Many things including the short term/acute effects of exericse and the Long term effects which are;Musculoskeletal response: increased blood supply; increase in muscle pliability; increased range of movement;muscle fibre micro tearsEnergy systems: phosphocreatine; lactic acid; aerobic; energy continuum; energy requirements of differentsport and exercise activitiesCardiovascular response: heart rate anticipatory response; activity response; increased blood pressure;vasoconstriction; vasodilationRespiratory: increase in breathing rate (neural and chemical control); increased tidal volumeCardiovascular system: cardiac hypertrophy; increase in stroke volume; increase in cardiac output, decreasein resting heart rate; capillarisation; increase in blood volume; reduction in resting blood pressure; decreasedrecovery time; increased aerobic fitnessMuscular system: hypertrophy; increase in tendon strength; increase in myoglobin stores; increased numberof mitochondria; increased storage of glycogen and fat; increased muscle strength; increased tolerance tolactic acidSkeletal system: increase in bone calcium stores; increased stretch in ligaments; increased thickness of hyalinecartilage; increased production of synovial fluidRespiratory system: increased vital capacity; increase in minute ventilation; increased strength of respiratorymuscles; increase in oxygen diffusion rateEnergy systems: increased aerobic and anaerobic enzymes; increased use of fats as an energy source(taken from a website - not my own work)
