Impact of surface on athletes
There are two types of surfaces used in any indoor or outdoor games. These are natural and artificial surfaces. Natural surfaces is the surfaces that are prepared through proper combination of natural elements like soil and grass. On the other hand, artificial surfaces are more like carpets which are made from artificial components like rubber, synthetic fiber etc. These surfaces impact performance of athletes differently. In many contact games like football, cricket, running and Kabaddi natural surfaces are preferred because they provide more familiarity, grip and avoid severe injuries. On the other hand, artificial surfaces provide more opportunities for practice because their use need not be stopped for maintenance. Also, with innovation in technology, artificial surfaces are becoming more user friendly. Risks of injuries are reducing in artificial surfaces also nowadays.
3 Impact of Surfaces and Environment on Athletes
9.4A. Sports Injury
|Intrinsic Risk Factor||Extrinsic Risk Factor|
Lack of proper training
Improper warming up & cooling Down
Over use of muscles
a. Poor techniques
b. Lack of knowledge
b. Playing Surface
c. Preventive surfaces
d. Medical facilities
Climatic conditions affect the performance
Environmental conditions, such as excessively high or low temperatures, have the potential to have a negative impact on an athlete‘s well-be ing. An athletes‘ ability to use a numberof thermoregulation techniques helps in regulating body temperature.
Sports injuries are those which are common in the field of games and sports. During training, competition or practice, any player can be injured. Perhaps there will not be any player who has not been injured during his career.
Strain is also a muscle injury. A strain is caused by twisting or pulling a muscle or tendon. A sudden strain is caused by a recent injury, lifting heavy objects or rods in wrong way and over stressing the muscles. Chronic strain are usually caused by moving the muscles and tendons in repetition.
Sprain is a ligament injury. It may occur due to overstretching or tearing of ligaments. Many things can cause sprain. Falling, twisting, or getting hit can force a point out of its normal position. This can cause ligaments aroung the joints to tear.Generally, Sprain occurs at wrist and ankle joints.
Prevention of sprain and strain
a) Conditioning should be performed during the preparatory period.
b) Sports equipments must be of good quality.
c) Play courts should be smooth and clean.
d) The scientific knowledge of games should be must for preventing srain.
e) Player should discontinue during the condition of fatigue.
f) Good officiating is essential for preventing such injury.
g) Players should be careful and alert during practice, training and competition.
Abrasion is a key injury generally occurs due to friction with certain equipments or a fall over the area where bone is very close to skin. It may be caused by a fall on hard surface. As someone falls or slides on the ground, friction causes layers of the skin to rub off.
Bruises are not clearly seen as upper skin remains undamaged and inner blood vessels are damaged and collect beneath the skin. A fresh bruise may actually be reddish and after a few hours it turns to blue or dark purple.
A laceration is a wound that is produced by tearing of soft body tissue.
Contusion is a muscle injury. A direct hit with or without any sports equipment can be the main cause of contusion. Contusion can also be due to minor accidents to the skin such as falling, bumping into something or being hit or kicked. In contusion blood vessels in muscles are broken and sometimes bleeding may occur in the muscles which may cause bruise.Stiffnes and swelling are common features at the site of contusion.
- Cold compression should be used immediately. Ice or cold water should not be used for more than 40 minutes persistently.
- The cold compression should be performed 5 to 6 times daily.
- If there is more swelling at the sight of contusion, the anti-inflammatory medicine should be given.
- If the swelling persists, consult the Doctor immediately.
- For the purpose of rehabilitation, flexibility exercises should be performed.
Causes of sports injuries
To effectively diagnose, rehabilitate and ultimately prevent subsequent injuries, a sport therapist
- Anatomical Factors: These are related to make up of the body. Leg length differences a n d cause injuries to ankle, hip and back.
- Age related causes As the body ages, it changes. It is less able to produce force, recovers slower and soft tissues lose the ability to stretch. Therefore it is more prone to injury.
- Training related cause’s Excessive repetitive loading of the tissues is needed for successive adaptation. However without suitable recovery, tissues never have the chance to adapt and can fail.
- Equipment selection factors These are related to the suitability of equipment. An instance is incorrect footwear, which will not protect the foot and ankle adequately. It also will not distribute forces effectively. Thus it increases the risk of injury.
- Impact and contact causes Impact or contact can be with objects, surfaces or other people. These injuries are common in contact sports like football, rugby, hockey etc. Also they are common in more dangerous sports like motor racing, boxing and skiing.
Joint injuries & its types
A hard blow to a joint, a fall, a forceful throwing, lifting or hitting may cause dislocation. Infact it is dislocation of surface of bones.
Types of dislocation
a) Dislocation of lower jaw: it occurs when the chin strikes to any other object. It may occur if mouth is opened excessively.
b) Dislocation of shoulder joint: dislocation of shoulder joint may occur due to a sudden jerk or a fall over a hard surface. The end of the humerous comes out from the socket. In face when your shoulder dislocates, a strong force, such as a sudden blow to your shoulder. Pulls the bones in your shoulder out of place.
c) Dislocation of hip joint: By putting maximum strength spontaneously may cause dislocation of hip joint. The end of the femur is displaced from the socket.
d) Dislocation of wrist: A sportsperson who participates in a sports or game in which he may fall, runs the risk of getting a dislocated wrist. A miscalculated landing can also cause a dislocated wrist. Infact, it generally occurs to the person who use his hand to break his fall.
a) Adequate warming-up should be performed prior to any activity.
b) Proper conditioning should be performed during preparatory period.
c) Stretching exercises should be include in warm-up
d) Players should be careful during training and competition.
e) Protective equipment should be used
f) Players should have good anticipation and concentration power
g) Always obey the rules and regulations.
h) Perform regular exercise around your shoulder, hip, and wrist joints etc.
i) Avoid falls or hits as far as possible.
Causes of fracture
Fracture usually occurs due to a high impact on the bone. It can be causes by overuse. The most common causes of fracture are:
a) In such sports event where there is a high impact.
b) Traumatic, forceful and unnatural movements.
c) Prolonged long distance walking or running.
d) Sudden fall on hard surface.
e) Direct strike or hit with any solid sports equipment.
Management of Fracture
a) Elevate the extremity and rest while bone heals itself.
b) Apply ice to the affected part for 24 to 48 hrs
c) If pain persists, give painkillers.
d) If there is any need of immobilization to the affected part, use a slint
e) After removal of swelling begin to put partial weight on the affected area.
f) Crutches or walking stick may be used in the beginning. After two weeks start putting normal weight.
g) For 6 to 8 weeks, avoid the activity that caused stress fracture. Then start doing the activity slowly.
