Benefits
A warm-up will improve the effectiveness of training and should be done before every training session. This is fundamental to a safe practice.
Direct physical effects are:
- Release of adrenaline
- Increased heart rate
- Enables oxygen in the blood to travel with greater speed
- Increased production of synovial fluid located between the joints to reduce friction
- Allows joints to move more efficiently
- Dilation of capillaries
- Enables oxygen in the blood to travel at a higher volume
- Increased heart rate
- Increase of temperature in the muscles
- Decreased viscosity of blood
- Enables oxygen in the blood to travel with greater speed
- Facilitates enzyme activity
- Encourages the dissociation of oxygen from haemoglobin
- Decreased viscosity within the muscle
- Greater extensibility and elasticity of muscle fibres
- Increased force and speed of contraction
- Greater extensibility and elasticity of muscle fibres
- Decreased viscosity of blood
- Increase of muscle metabolism
- Supply of energy through breakdown of glycogen
- Increase in speed of nerve impulse conduction
- Removes lactic acid

Famous quotes containing the word benefits:
“In America the young are always ready to give to those who are older than themselves the full benefits of their inexperience.”
—Oscar Wilde (1854–1900)
“Unfortunately, we cannot rely solely on employers seeing that it is in their self-interest to change the workplace. Since the benefits of family-friendly policies are long-term, they may not be immediately visible or quantifiable; companies tend to look for success in the bottom line. On a deeper level, we are asking those in power to change the rules by which they themselves succeeded and with which they identify.”
—Anne C. Weisberg (20th century)
“Through all opposition the personal benefits of the reform [dress] [bracketed word in original] have compensated; but had it been mainly sacrifice, the thought of working for the amelioration of women and the elevation of humanity would still have been the beacon-star guiding me on amid all discouragements.”
—Susan Pecker Fowler (1823–1911)
