Chang-Hwa Bank make their warming up for knees to prevent damage and accident at 2006 Taipei 101 Run Up on October 22, 2006.
A warm up is usually performed before participating in (technical) sports or exercising. A warm up generally consists of a gradual increase in intensity in physical activity. For example, before running or playing an intense sport one might slowly jog to warm muscles and increase heart rate. It is important that warm ups should be specific to the exercise that will follow, which means that exercises should prepare the muscles to be used and to activate the energy systems that are required for that particular activity. The risks and benefits of combining stretching with warming up are mixed and in some cases disputed. Warming up prepares your body mentally & physically.
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:
- 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
- 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
- Increase of muscle metabolism
- *Supply of energy through breakdown of glycogen
- Increase in speed of nerve impulse conduction. They use it before competitive matches to intimidate opposition, raise morale and generally raise confidence in the team.

Stretching, as theorized in literature, is the deliberate act of lengthening of muscles, in order to increase muscle flexibility and/or joint range of motion (Weerapong et al 189-206).

Heart rate is a term used to describe the frequency of the cardiac cycle. It is considered one of the four vital signs. Usually it is calculated as the number of contractions (heart beats) of the heart in one minute and expressed as "beats per minute" (bpm).

Friction is the force of two surfaces in contact. It is not a fundamental force, as it is derived from electromagnetic forces between atoms. When contacting surfaces move relative to each other, the friction between the two objects converts kinetic energy into thermal energy, or
