Q

What is a chronic injury?

A

An injury which occurs due to excessive pressure on bones and muscles. Where muscles, bones, become weaken over time performing. An overuse injury rather than mechanical.

13
Q

What is Achilles tendinitis.

A

Occurs due to the overuse of the Achilles’ tendon where it breaks down and rubs against the bone causing swelling & pain in an athlete’s Achilles’ tendon.

Q

What is screening?

A

A method used to identify people who may have complications playing sport; helps prep for exercise; enhance performance and reduce injury.
Can also highlight past or current injury

17
Q

Give examples of tests used in screening

A

• Electrocardiogram (ECG) - electrodes place of the chest, w/ wires connected to print out electrical activity of the heart
• assessing muscular imbalances, core strength, range of movement, mobility and postural alignment and if there are any issues, programme is formed to improve performance

18
Q

What are the disadvantages of screening?

A

• not 100% accurate:
- can give false positive (miss a problem)
- can give false negative (identify a problem that doesn’t exist)
• gives player anxiety if they have a health problem

19
Q

Give some examples of protective equipment

A

• football - ankle/shin pads
• rugby - scrum cap, gum shield, body armour
• cricket - batting pads, thigh pads, box, helmet, gloves
• hockey - gum shield, gloves helmet, leg guard, pads, kickers, face mask for short corners
• squash - eye guards

20
Q

How does warming up impact performance?

A

• reduces possibility of injury as increases muscle temp and therefore elasticity
• HR and RR increased so starts delivery of O2 and nutrients to working muscles, prepping muscles, joints and tendons for strenuous activity

21
Q

What is the structure of a warm up?

A
  1. Pulse raiser/ CV exercise e.g. jogging = gently increasing heart rate + breathing rate + activating vascular shunt towards muscles
    2 . Stretching / flexibility exercises
    3 . Skill-based practice / movement patterns
22
Q

What are the 4 types of flexibility training?

A

• active stretching
• passive stretching
• static stretching
• ballistic stretching

23
Q

What is active stretching?

A

Where a stretched (and relaxed) antagonist muscle position is caused by the contraction of its agonist.
e.g. lifting leg up and holding it in a position

24
Q

What is passive stretching?

A

Using an external force to aid the stretched position
e.g. pushing against a partner or a wall

25
Q

What is static stretching?

A

Stretching whilst not moving; holding the muscle in the furthest place for up to 30 seconds
e.g. touching your toes

26
Q

What is ballistic stretching?

A

Using swinging and bouncing movements to push a muscle / body part further
e.g. swinging leg back and forth to stretch hamstring and glutes

27
Q

List rehabilitation methods of training?

A

• proprioceptive training
• strength training
• hyperbaric chambers
• cryotherapy
• hydrotherapy

28
Q

List recovery methods of training

A

• compression garments
• massage
• foam rollers
• cold therapy
• ice baths
• cryotherapy

29
Q

What is proprioceptive training?

A

Using jumping, hopping and balance exercises to restore lost proprioception and to teach the body to control the injured joint subconsciously
e.g. balance board

30
Q

What is strength training and what are the different methods used?

A

The use of resistance to prepare body for exercise and reduce chance of injury
• free weights - weights that have to be controlled when lifted, muscles have to stabilise while lifting e.g. DBS and KBs
• machine weights - used in early stages of injury; lifting weight that is under the control of a machine e.g. lat pull down machine / leg press / smith machine
• body weight - using body as resistance to improve core strength = improved imbalances that could lead to injury
• therabands - elastic latex bands that increase in strength as development occurs

31
Q

What are hyperbaric chambers?

A

Reduces recovery time by filling a chamber with 100% oxygen to reduce swelling and stimulate white blood cell activity and increase blood supply around injury site.

32
Q

What is cryotherapy (rehab of injured area)?

A

The use of cold temperature to treat injury e.g. Rest Ice Compression Elevation in injured area

33
Q

What is hydrotherapy?

A

The use of the buoyancy of warm water (35-37°C) to help support body weight to reduce load on joints / injury. Exercising against resistance of water strengthens injured area. It also improves blood circulation, relieves pain and relaxes muscles.

34
Q

What are compression garments?

A

The use of tight fabric to improve blood circulation, help blood lactate removal, reduce inflammation and problems relating to DOMS and prevent medical issues like deep vein thrombosis (blood clot in deep vein)

35
Q

What is a massage?

A

A treatment involving release of tension in soft tissues which can:
• increase blood flow to soft tissue so more O2 and nutrients can repair any damage
• removes lactic acid
• breaks down scar tissue which if not removed can lead to mobility problems in soft tissue

36
Q

What do foam rollers do?

A

‘Self-massage’ but relieves tension between the muscle and fascia (a fibrous layer of connective tissue that surrounds muscle group). Used to prevent injury and improve mobility.

37
Q

What do ice baths do?

A

A recovery method that involves sitting/standing in an ice cold bath for 5-10 minutes. Vasoconstriction around muscles and near surface as vasodilation occurs at the core to keep it warm. The flush of blood bring fresh oxygen to the working muscles, removing lactic acid, helping cells to better function and reduce soreness.

38
Q

What is cryotherapy (recovery in day to day exercise)?

A

Whole body cryotherapy involves stepping into a cryogenic chamber below -100°C for up to 3 minutes, initiating vascular shunt mechanism; when fresh blood returns to the muscles, more oxygen is provided, flushing out lactic acid, reducing inflammation and soreness.

39
Q

What is the importance of sleep and nutrition for recovery?

A

• Deep sleep is important for muscle recovery (3rd stage of NON-REM sleep) - where the brain waves are at their slowest, away from the brain to the muscles to restore energy.
•Minimum of 8-9 hours sleep is needed for a regular athlete.
• glycogen stores need to be replenished after exercise (first 20 mins post exercise = enhanced performance next day) Chocolate milk in first 20 mins post-exercise to optimise recovery
• 3:1 to 4:1 carbs to protein = resynthesise muscle glycogen more efficiently than carbs alone
