Flashcards in LEWIS: Sports Injuries Deck (81):
1

Injuries can be prevented by:

-using the correct equipment (mouth guards or pads)
-wearing correct clothing (trainers with good friction/support)
-using training methods that allow for rest days
-including warm ups and cool downs in training sessions

2

Taping is used to prevent

ligament injuries

3

Bracing is used to provide

extra stability to the joint

4

Taping must be done expertly if its to provide support without limiting

mobility

5

Bracing must be fully adjustable so that they can limit

movement in joints where ligaments have been stretched as a result of an earlier injury

6

equipment used to protect themselves from:

impact or penetrative injuries

7

Examples of protective equipment:

-mouth guards
-helmets
-knee pads
-eye protectors

8

footwear must also give sufficient

friction or traction against the ground without gripping excessively that performers suffer from ankle or knee injuries due to rotational forces

9

Footwear for optimal performance and protection, must be :

-correct size
-suit the foot of the individual

10

Footwear can be suited by:

-arch of foot
-gait analysis
-understanding of how an individual runs

11

3 ways an individual:

-Neutral
-Pronated
-Supinated

12

Neutral means:

heel makes contact with ground and travels in a straight line

13

Pronated means:

heel hits ground but the foot moves to the side

14

Supinated means:

heel hits ground first and foot rolls outward

15

Appropriate clothing can help avoid

sport-related/environmentally related injuries

16

(Clothing) outdoor adventure activities, it is important to stay warm and dry. The risk of hypothermia is significantly increased if you get wet and cold, especially if there is the associated danger of

wind chill

17

(Clothing) competing in high temperatures, important to decrease chances of suffering from heat cramps, heat exhaustion and heat stroke. Wearing synthetic, microgfibre type clothing that allows the sweat to 'wick' away from the body quickly will help the performer avoid problems with:

overheating and discomfort

18

Avoid overheating by:

-ingesting plenty of fluids
-warming up in the shade
-acclimatise body by training in same temp. and humidity

19

What type of training can reduce/prevent injury:

core strength/stability

20

Conditioning work that is undertaken must relate specifically to:

-physical demands of the activity
-focus on common injuries

21

Core strength training involves developing the deep trunk muscles, paraspinal muscles and the pelvic floor muscles which then help stabilise the spine. Before any movement takes place, these muscles contract to give trunk stability which helps:

control movement and transfer energy

22

Conditioning that improves core strength can help improve performance posture and makes the performer less prone to:

lower back injuries and pain

23

Core strength training can be undertaken by using

body-weight exercises
balance boards
isometric exercises

24

Strong, well-conditioned muscles act as important balancing agents for the forces that are generated throughout the body when we engage in physical activity. When muscles are strong, they help to reduce the

repetitive strain that occurs

25

Overtraining can be caused in 2 ways:

-overstressing the body during training sessions
-not allowing sufficient time for recovery after an intense training session or performance

26

Characteristics of an overtrained performer:

-Long lasting fatigue
-Worsening of performance under competitive conditions
-tempted to work harder to improve their physical condition

27

Fatigued and tired muscles provide inadequate support for tendons, ligaments and bones; thereby increasing the risk of

strains, sprains and stress fractures

28

symptoms of overtraining:

-deep muscle soreness
-persistant nagging injury
-difficulty in working hard enough to raise the HR to the desired training level
-loss of appetite
-recurrent sore throats and flu-like symptoms
-not sleeping properly

29

To avoid injury caused by overtraining, performers should:

-allow sufficient recovery time
-restore glycogen stores after hard sessions or performances
-not train when ill
-build up training loads gradually after illness
-try and use meditation or relaxation techniques to improve sleep
-ensure that diet is nutritionally balanced

30

To train children as if they are small adults risks causing damage to developing

joints and musculature

31

overtraining using inappropriate training regimes for strength/speed development for children can lead to:

inflammation of tendons, mild tendonitis and stress fractures

32

The Long Term Athlete Development programme (LTAD) is a strategy for developing performers from childhood through to adulthood. It has valuable advice for preventing

inappropriate training and coaching programmes for children

33

LTAD identifies 2 overlapping stages:

FUNdamental (5-11)
Learning to Train (8-12)

34

FUNdamental stage should be:

-fun
-quality participation in a wide range of sports
-development of motor skills
-development of agility, balance and coordination
-low voluming training for speed and endurances using FUN games
-simple rules and ethics of sports
-strength training using child's own body weight

35

Learning to Train stage involves:

-further development of fundamental skills
-learning general overall sports skills
-continuing strength development
-basic flexibility exercises
-develop endurance with games and relays
-develop speed with specific activities during the warm-up
-developing knowledge of warming up, cooling down, stretching, hydration, nutrition, recovery, relaxation and focusing
-structuring of any competition

36

Endurance athletes are advised to have a high

carbohydrate diet

37

to reduce risk of injury through being overtired, some athletes increase their carbohydrate intake when engaged in

heavy training or high level competition

38

Each time you exercise, glycogen becomes

depleted to a certain extent

39

To delay fatigue during exercise, take carbohydrates in drink form to ensure easier and quicker

absorption

40

To avoid hypoglycaemia (low blood sugar) during exercise, carbohydrate should not be consumed within

one hour of the start of exercise

41

glycogen loading causes a temporary increase in the levels of glycogen in the body just prior to competition by convincing the body to store more

glycogen than normal

42

5 Features of an active warm up:

-general cardiovascular warm up (5-10min) - raises body temp to enhance elasticity of muscles, tendons, etc.
-focusing/concentrating their mind for the training session or performance
-followed by range of 8-10 dynamic exercises that address all the major muscle groups
-specific to sport, mimicking the actions involved in the activity
-Increasing level of intensity

43

8 Benefits of a warm up:

-maintenance of warmth in body and muscles
-preparation of muscles and joints in a more sport specific manner (static stretching)
-improvement of coordination and motor ability as well as energising the nervous system
-mental preparation
-increased metabolic activity (tissue respiration processes/breaks down fuel at a quicker rate)
-blood shunting occurs
-reduces blood viscosity
-increased breathing rate (better GE due to greater diffusion gradient)

44

3 stages of warm up:

-pulse raiser (5-10 mins CV)
-sport specific dynamic stretches (8-10)
-sport specific drills (increase intensity levels throughout)

45

Cool-down is designed to decrease any injurious effects, and prepare for next session. It can do this by:

-preventing blood from pooling in the limbs and lactic acid from building up in the muscles

46

cool down helps muscles and tendons to:

relax and loosen, stopping them from becoming stiff and tight

47

13 benefits of cool down:

-helps muscles and tendons to relax
-prevents blood pooling in limbs
-prevents lactic acid build up in muscles
-continues metabolic processes
-keeps blood flowing
-maintains venous return (skeletal pump)
-removes CO2 and lactic acid
-flushes capillaries with oxygenated blood
-maintains elevated blood pressure
-purges oxygen debt
-reduces HR to resting
-returns body temp. and breathing rate gradually
-reduces DOMS effects

48

DOMS =

delayed onset of muscle soreness

49

DOMS is caused by:

damage to muscle fibres and connective tissue (inflammation and increased local muscle and eccentric muscle contractions)

50

6 ways to avoid DOMS:

-undertake an active dynamic warm-up
-avoid movements that entail strenuous eccentric muscle action at start of training programme
-gradually increase exercise intensity and duration
-after initial stages: do extra amounts of eccentric exercise that may cause/have caused DOMS
-undertake an active cool-down (include passive stretching)
-consider therapeutic massage

51

to recover from soft tissue injury or general fatigue, 9 ways to recover:

-light aerobic activity
-stretching
-therapeutic massage
-contrast showers
-sleeping/lying down still
-ice baths
-food
-hydration
-whirlpool baths

52

What treatment is used for acute soft-tissue injury:

RICE

53

R =

Rest as soon as injury occurs

54

I =

Ice, injured area should be iced for 10-15 minute then taken off for 20 min

55

Ice reduces the

internal bleeding (due to vasoconstriction) and the flow of fluids from damaged cells and controls inflammation and swelling

56

C =

Compression, reduces or helps control swelling

57

E=

Elevation, helps reduce swelling and inflammation

58

Elevation is most effective if the injured area is elevated above the level of the

heart

59

Cryotherapy is the use of cooling measures to treat

chronic or acute injuries

60

Cryogenic chamber therapy is a treatment for

muscle and joint pain

61

It is important to replenish the carbohydrate and the glycogen stores

after exercise

62

during the core strength training for the rehabilitation phase, the performer should focus on the whole movement/kinetic chain - a deficiency in one part of the chain can cause a problem or an injury in

another part

63

Water training is often used when athletes need to

maintain cardiovascular fitness while continuing their sport-specific training patterns, but without exposing the damaged tissues to further trauma

64

To undertake aquatic therapy, the performer adopts a running posture from that basic technique almost any sport-related movement can be

developed and replicated

65

Therapeutic massage is the application of massage techniques to the

muscle and connective tissues of the body to enhance and maximise sport performance

66

Therapeutic massage is used to increase the

range of movement and flexibility and to relieve muscle soreness

67

Therapeutic massage may help injury prevention and promote

faster recovery from high-intensity training and injury

68

(PROPRIOCEPTIVE TRAINING) Proprioception is the coordination of balance and joint-positioning sense. For smooth and coordinated movements to be produced, the brain must know accurately the position of the limbs and joints and also the

rate of movement of the limbs

69

Proprioception info comes from the proprioceptors in the:

joints, tendons and muscles (GTO and muscle spindles)

70

If proprioceptive sense isn't retrained after injury, it is likely to cause a recurrence of the

injury

71

Aim of hyperbaric chambers:

-Reduce recovery time for an injury

72

Outline of hyperbaric chambers:

-Uses pressures higher than the local atmospheric pressure
-The pressure increases the amount of oxygen that can be breathed in, which means more oxygen can be diffused to the injured area

73

Hyperbaric chambers simulate:

-air pressure at altitude or depth

74

Benefits of hyperbaric chamber:

-Boosts white blood cell activity in injured areas (controlling infections)
-Vasoconstriction (reduces blood flow to injured area) - helps to reduce pressure and swelling
-More oxygen can reach the injured area
-Enables quicker healing time
-Reduces lactic acid build up

75

Effects of hyperbaric chambers:

-Hyperoxia
-Enhanced oxygen delivery
-Saturates blood plasma and haemoglobin with oxygen
-RBCs = more malleable (increases their ability to pass through restricted blood vessels)
-Increased oxygen saturation throughout the body allows body to get oxygen required for ATP resynthesis for energy

76

Oxygen tents, also known as

hypoxic tents

77

Oxygen tents simulate:

effects at high altitude by providing a low-oxygen environment

78

Oxygen tents - oxygen depletion causes production of higher levels of

haemoglobin (more oxygen can be extracted from the blood for extra energy)

79

Oxygen tents used for:

endurance athletes

80

Benefits of oxygen tents/hypoxic:

-Higher VO2 max - recovery from injury more quickly as more oxygen can reach the injury enabling cells to heal
-Aids quicker tissue regrowth
/
-improves athlete's ability to work as more O2 is available to working muscles
-increases oxygen carrying capacity of blood
-produces more RBC and haemoglobin

81

Oxygen tents do not speed recovery, but do mean that after recovery, they will have retained a level of fitness that allows them to

return to sport almost immediately and achieve some of the positive adaptations of altitude training
