23
Q

Advantages of screening?

A

. Professionals use this to prevent injury. Involves assessing muscle imbalances, core strength, range of movement, postural alignment and mobility
. Detected problems are then worked on by strength and conditioning coaches

24
Q

Disadvantages of screening?

A

. Screening can cause anxiety in performers or identify a problem that doesn’t exist (false positive) or miss a problem (miss negative)
. It isn’t 100% accurate

25
Q

Purposes of screening?

A

. Identify past or current injuries and prevent further injuries
. Identify imbalances, assess joint mobility, identify postural weaknesses
. Identify cardiac risks or other general risks

26
Q

What is protective equipment?

A

Creates a protective barrier between the performer and the object

27
Q

How does a warm up prevent injury?

A
  1. Raises body’s muscle temperature
  2. Blood flow increases the amount of O2 and nutrients to the muscle
  3. Increased elasticity of muscles
  4. Joints and tendons prepare for strenuous activity
  5. Heart rate increases
  6. Respiratory rate increases
28
Q

What are the three phases of a warm up?

A
  1. General pulse raiser
  2. Stretching
  3. Sports specific
29
Q

What are the 4 types of stretching?

A

. Ballistic
. Active
. Passive
. Static

30
Q

What is ballistic stretching?

A

Uses swinging and bouncing movements

31
Q

What is active swinging?

A

When a stretched position is held by the contraction of an agonist muscle

32
Q

What is passive stretching?

A

Use of an external force to help the stretched position

33
Q

What is static stretching?

A

When a muscle is held in a stationary position for more 10 seconds or more

34
Q

What is taping and bracing?

A

. Weak joints can be supported and made more stable
. Stops further injury and allows rehabilitation to begin
. Kinesiology tape is used on muscles as it has less flexibility

. Bracing is more substantial and involves hinged supports
. Extra stability

35
Q

What is proprioceptive training?

A

Teaches your body to control the position of a deficient or an injured joint

36
Q

How can proprioceptive training be done using a wobble board and why is it beneficial?

A

. The unpredictable movements of the balance board re-educates your body quickly
. Teaches the body to control the position of joints subconsciously
. Involves hopping, jumping and balancing activities
. Easily accessible

37
Q

What are the different strength training methods?

A

. Free weights
. Machine weights
. Body weight
. Therabands

38
Q

What are free weights and why can they be used?

A

Free weights are dumb bells, kettle bells are controlled by the individual whilst lifting. The varying degrees of weight can be used to build up to full strength and can target specific injured muscle groups more easily

39
Q

What are machine weights and why can they be used?

A

The machine has control, there are set movement patterns. They are useful for early stages of injury as they are controlled

40
Q

Why is body weight exercises used?

A

These exercises put less stress on the body, as the performer is only required to hold their own body weight, this allows injured muscles more chance of recovery

41
Q

What are therabands and why are they used?

A

They are elastics that provide resistance. Resistance increases as injury improves. They offer variety in resistance so can also be used in early stage of injury

42
Q

Pros and Cons of therabands?

A

+
. Different bands of varying resistance, allowing athletes to choose the correct resistance depending on the stage of their injury

-
. Therabands can snap causing further injury

43
Q

Pros and Cons of body weights?

A

+
. Useful because they are low impact -> good for early stage of recovery

-
. Less opportunity to overload and build strength to high degree

44
Q

Pros and Cons of machine weights?

A

+
. Provide athlete with a lot of control allowing them to improve strength

-
. range of motion by machine may be limited
. tends to focus on larger muscle groups
. movements don’t always mimic sporting actions

45
Q

Pros and Cons of free weights?

A

+
. performer can make exercises sports specific
. ensures correct muscles are strengthened

-
. poor form/technique can lead to further injury

46
Q

What is hydrotherapy and how does it help injury?

A

. In warm water (35-37 degrees)
. Improves blood circulation, relieve pain and relax muscles
. Buoyancy of the water supports the body reducing the load on the joints allowing more work than on land
. Exercising against the load of the water helps strengthen the injured area
. The buoyancy of water can help support injured joints (hydrostatic pressure)
. Can include squats, lunges, walking and running

47
Q

What are hyperbaric chambers and how does it help injury?

A

. Pressurised like an aeroplane where they have 100% pure oxygen
. The pressure increases the oxygen breathed in and absorbed into the injured area
. Excess oxygen dissolves into the blood plasma reducing swelling as haemoglobin becomes saturated with O2
. Increases white blood cell production and supply to the joint
. Removes lactic acid
. Reduces recovery time

48
Q

What is cryotherapy and how does it help injury?

A

. The use of cold temperatures to treat an injury
. RICE is used on common muscle strains (Rest, Ice, Compression, Elevation)
. Limits pain and swelling by reducing blood flow
. Whole body cryotherapy (WBC) is a chamber cooled to below -100 degrees, people are given socks, gloves, and a swimming costume, can only stay for up to 3 mins
. Through vasoconstriction blood is taken back to the core to keep warm
. When placed back in a warm environment, the blood floods back bringing O2 to help injured cells

49
Q

How do compression garments help injury?

A

. They improve circulation to stop deep vein thrombosis (DVT)
. They can be used in sport to reduce inflammation and aid lactate removal
. Also reduces delayed onset of muscle soreness (DOMS)

50
Q

How do massages help injury?

A

. Regular exercise creates tension in soft tissue which is released by massage
. Benefits inc: - improved blood flow, increased nutrients and O2 to aid healing, removal of lactic acid, stretches soft tissue releasing tension and pressure, breaks down scar tissue which can cause mobility issues

51
Q

How do foam rollers help injury?

A

. Releases tension between muscle and fascia
. Improves mobility and prevent injury by improving blood flow

52
Q

How does cold therapy help injury?

A

. Cools the surface of the skin using ice causing pain relief
. Vasoconstriction on the vessels decreasing blood flow and reducing swelling
. Can reduce muscle spasms by reducing motor nerves
. Decreases metabolic rate

53
Q

How does ice baths help injury?

A

. Body restricts blood flow
. Vasodilation occurs when you leave the bath so oxygenated blood rushes to the muscles bringing oxygen
. Speeds up recovery

54
Q

What does a lack of sleep cause?

A

. Lack of REM sleep causes less blood to be available for recovery
. Inefficient sleep causes a reduction in growth hormone production
. Reduced concentration/ repair
. Cause tiredness

55
Q

What is the effect of a lack of sleep on the performer?

A

. Low recovery and performance levels
. Fatigue and slow recovery
. Risk of injury increased
. Lack of concentration/ slow reaction times

56
Q

How soon after should nutrition/energy be taken in after activity?

A

Within 20 minutes

57
Q

Why should you consume liquid after activity rather than food?

A

Liquid is absorbed far more quickly than solid so provides a quick raise in energy levels from drinks to aid recovery
