Warming Up

, 2006 .]]

A warm up is usually performed before participating in (technical) Sport s 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.

--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

#---Makes performers more alert

Psychological effects:

---For very specific groups of people, warm ups may boost the Morale of people before sports matches, especially if the warm up includes Superstitions or Rituals .
