the effects of a warm up on the cardiovascular system and the muscular system

muscular system

cardiovascular system

Increasing the heart rate

which increases

stroke volume

cardiac output

venous return

decrees in blood viscosity

meaning it will follow more readily through the vessels

transporting O2 to the working muscles quicker

helping to delay OBLA

Greater strength of contractions

due to improved elasticity of muscle fibres

faster speed of contractions

due to increased speed of nerve transmissions to the muscle fibres

faster speed of contractions and relaxation of the muscle fibres

due to an increase in muscle temperature

reduced risk of injury

due to an increase in muscle elasticity

an increase in coordination between antagonistic pairs

due to a reduction in muscle viscosity
