Fracture is a bone injury that breaks the continuity of a bone or separates it into two or more parts.
The first aid techniques for fractures are as follows
• Immediately immobilise the injured area. Do not try to re-align the bone or push back in a bone that may be sticking out.
• Apply ice packs to limit swelling and help relieve pain until medical help arrives.

A weightlifter with a weight of 60kg has lifted a barbell weighing 80kg and is holding it above his head. As long as he is holding the barbell, both the bodies (weightlifter and barbell) are in static equilibrium. Same concept is applicable in cricket when a fielder tries to catch a ball with wider legs because a wider base provides higher stability.

i. Increased blood supply: During exercise, in order to match demand of fuel to muscle, the supply or concentration of blood increases in the whole body or, in the particular muscle group where activity is largely impacted.
ii. Increased muscle temperature: During exercises muscles demand energy, which comes from contracting muscles. During the process, a lot of heat energy is generated which increases the temperature of muscles, and/or the body.
iii. Increased muscle flexibility: Due to an increase in blood flow and rise in temperature, elasticity of muscles increases. Stretching and mobility exercises also play a dominant role in increasing muscular flexibility.
