B6 Injuries


B.6.1  Discuss the need for warm-up routines

  • A warm-up routine involves gentle exercise before undertaking strenuous activity in an effort to prevent the occurrence of injury
  • It is aimed at increasing blood flow and oxygen supply to muscles, as warm muscles and joints are more supple and less likely to be strained
  • However there is limited scientific proof as to the benefits of a warm-up – some people do not suffer ill effects from not warming up

B.6.2  Describe injuries to muscles and joints, including sprains, torn muscles, torn ligaments, dislocation of joints and intervertebral disc damage

Sprains:  Injuries to ligaments in a joint, caused by the over-extension or sudden violent movement of a joint beyond its normal range

Torn muscles:  Most severe case of a muscle strain, caused by incorrect movement placing too much pressure on a section of a muscle, creating a tear

Torn ligaments:  When a ligament is stretched with enough force (usually requiring a fall or other form of accident) it may partially or completely tear

Dislocation of joints:  A dislocation is when bones in a joint are moved relative to one another and don't return to their original position

Invertebral disc damage:  Due to excessive pressure (e.g. heavy lifting), invertebral discs may bulge out and put pressure on the spinal nerves
