what happens to the area of a stress fracture
becomes tender and swollen
where are stress fractures most common
in weight bearing bones of the legs
what else can contribute to a stress fracture
- unfamiliar surfaces
- inappropriate equipment
how does a stress fracture occur
the fatigued muscle transfers the stress overload to the bone which results in a tiny crack

define an intrinsic risk factor
factors from within the body
describe the intrinsic risk factors of injury
- aspects of an athletes physical makeup or individual variables like poor posture and alignment, previous injury and insufficient nutrition
- training effects such as inappropriate flexibility, strenght imbalance and poor preparation for training
give and example of poor preparation
running a marathon without adequate training beforehand
what should preparation for an activity include
- warm up
- nutrition
- hydration
- sleep
- training
describe previous injury as an intrinsic risk factor for injury
- weakness in connective tissues
- imbalance between muscle groups
- decreased joint stability
- altered biomechanics
describe posture and alignments issues as an intrinsic risk factor for injury
different leg lengths, scoliosis or lordosis (misalignment can cause joints to weaken and muscular imbalances)
describe age as an instrinsic risk factor for injury
increases risk of injury as bone tissues loses strength and connective tissues suffer overuse, wear and tear they become prone to injury
describe age as an instrinsic risk factor for injury
increases risk of injury as bone tissues loses strength and connective tissues suffer overuse, wear and tear they become prone to injury
describe nutrition as an intrinsic risk factor for injury
for prevention and recovery:
- protein = growth and repair.
- carbohydrate for energy and prevent fatigue, fats for protection and cushioning
- vitamins and minerals such as VD and calcium for growth and repair
define inadequate fitness as an intrinsic risk factor for injury
leads to injury if the intensity, duration and frequency of training or ability of opponesnt are too high
explain what eaely fatigue leads to
- poor technique
- wrong decisions
- drop in performance
describe inappropropriate flexibility level as an intrinsic risk factor for injury
a lack of flexibility in the connective tissues can limit range of motion and lead to sprains/ strains
how can flexibility be improved prior to performance to help prevent injury
- an appropriate warm up with sport specific mobility exercises may increase performance while limiting risk
define an extrinsic risk factor for injury
injury risks or forces from outside the body
identify extrinsic risk factors for injury
- poor biomechanical training and performance techniques
- incorrect equipment and clothing
- inappropriate overload without progression and lack of variance in training
describe incorrect equipment and clothing as an extrinsic risk factor for injury
- equipment must be suitable for age, stature and ability of participant
- e.g. mini-tennis by lawn tennis = smaller court, racket, net lower and bouncing balls to reduce injuries to skeleton
decsribe poor performance techniques as an extrinsic risk factor for injury
- using poor technique puts excess strain on the muscles, tendons and ligaments
- chronic injury e.g. tennis elbow is associated with poor backhand technique
- acute injury e.g. poor technique with free weights can cause strains
how do coaches play an essential role in preventing injuries caused by poor biomechanical training and technique
- teach correct technique
- warm up routines
- practices are appropriate for age and ability of player
give an example of why coaches must be up to date with guidelines
e.g. rugby chnages to scrum engagement
- step instructor ensuring correct equipment and routine is within performers ability
describe how equipment can help prevent injury from extrinsic risk factors
- protective equipment can be worn e.g. netballer wear ankle braces
why do athletes wear sport specific clothing
to maximise performance and avoid injury
give example of sport specific clothing
describe what technelogicsl fabrics can do
- second skin : increases flexibility for gymnast so they can use their full range of motion OR helps cyclist by minimising air resistance so limits fatigue as clothing is smooth
- wick away moisture: aiding in thermoregulation
- be light weight
- contain padding : shoulder girdle in American football prevents fractures and dislocations
how can footwear aid in prevention of injury in sport and give an example
- designed to meet demand of sport
- can be specific to the athlete and the splaying surface
e.g. distance runners require cushioning for shock/ absorption/ basketball trainers have lateral ankle support
describe how inappropriate overload without progression and lack of variance can be an extrinsic rsk factor for injury
- progressive overload must be appropriate for age, ability, stature and injury status of athlete
how can injuries occur with inappropriate overload wihtout progression and lack of variance
- if intensity is too high
- the frequency or duration is too great
- no variance may cause repetitive strain
describe how warming up thoroughly will reduce the risk of injury
- it increases muscle elasticity
- increases bodys muscle temperature
- increase heart rate & respiratory rate
- increase blood flow and so delivery of oxygen and nutrients to working muscles
explain the 3 stages of a warm up
- perform cardiovascular exercise e.g. jogging to gently increase heart rate & so increase cardiac output, breathing rate so more blood is directed to wokring muscles (vascular shunting) recieving more oxygen
- stretching/ flexibility/ & mobility exercises
- sport specific drills to activate neural pathways & rehearse movement pathways
how long should a warm up last
20-45 mins with gradually increasing intensity
describe how cooling down will help active recovery
- removes waste products like lactic acid and CO2

- prevent blood pooling
- prevent delayed onset muscle soreness
how long should you cool down for
20-30 mins by gradually decreasing in intensity
describe the distinct stages of a cooldown
- moderate intensity activity of 40-55% VO2max to maintain HR, venous return mechanisms and blood flow to remove waste products
- stretching exercises to reduce muscle tension, increase muscle relaxation and gradually lower muscle temperature
define delayed onset of muscle soreness
pain and stiffness in muscle, which peaks 24-72 hours after exercise, associated with eccentric muscle contracation
describe how you would assess a sports injury in sport
SALTAPS
- STOP: stop the game if player is injured
- ASK: ask questions about injury e.g. where does it hurt
- LOOK: search for signs such as bruising, swelling, broken skin, bleeding or foreign objects
- TOUCH: gently palpate the injured area to indentify painful regions of inflammation
- ACTIVE MOVEMENT: ask the player whether thay can move the injured area without assistance
- PASSIVE MOVEMENT: if there is movement then gently move the injured area through its range of movement
- STRENGTH TESTING: ask the player to stand, lift or put pressure on the injured area if they can
describe acute management of soft tissue injuries
PRICE
- PROTECTION: protect the injury from further damage e.g. splint
- REST: allow time to heal and prevent further damage
- ICE: apply ice indirect to skin to reduce inflammation and pain - 10 mins of ice application, repeat after 60 min break
- COMPRESSION: compress the injury with tear tape, crepe or stretch bandage to reduce swelling
- ELEVATION: raise the injury above the heart level to reduce blood flow to the area and reduce swelling
what are the 6Rs for recognising a concussion
- RECOGNISE: players, parents, coaches, officials shouls be aware of the signs and symptoms of concussion
- REMOVE: if the player has a concussion or is suspected of having a concussion they must be removed from field or play immediately
- REFER: must go to a qualified healthacrre professional to assess and treat the condition
- REST: players must rest from exercise until symptom free and not be left alone for 24 hours
- RECOVER: players must fully recover before returning to play (adults minimum 1 wek, u18s 2 weeks)
- RETURN: to return to play the athlete must be symptom free and have writeen authorisation to return
define rehabilitation
the process of restoring full physical function after injury has occured
describe the 3 sages of rehabilitation
- early stage: gentle exercise encouraging damaged tissue to heal
- mid stage: progressive loading of connective tissues and bones to develop strength
- late stage: functional exercises and drills to ensure the body is ready to return to training
what is the aim of massage as a method of rehabilition of an injury
to prevent or relieve soft tissue injuries
describe the benefits of a sports massage
- increase blood flow to soft tissue so more oxygen & nutrients can pass through to help repair any damage
- removes lactic acid
- causes stretching of soft tissue to relieve tension and pressure
- breaks down scar tissue, which if not removed can lead to mobility problems in muscles, tendons and ligaments
describe the 3 stages of rehabilitation when stretching
- acute stage: first 3 days no stretching as part of PRICE. complete rest is needed
- mid phase: gentle rehab up to two weeks, heat therapy and gentle and passive stretching
- later phase: for a further 2 weeks focus on range of movement, strength & coordination. PNF can be done besides static and passive stretctching techniques.
why is stretching used as a long term method of rehabilitiation of injury
important to increase strength and range of motion in your connective tissues
describe the aim of cold therapy as a method of recovery
useful after intense exercise where it can target any minor aches and pains
explain how cold therapy works as a method of injury recovery
- cooling the surface of the skin using ice gives pain relief and causes vasoconstriction of the blood vessels which decreases blood flow and reduces bleeding and swelling
- a decrease in swelling enables the muscles to have more movement
- ice can also reduce muscle spasms by decreasing motor activity
- speed of nerve impulses slow down due to cold conditions
- metabolic rate is decreased
describe the aim of cryotherapy as a method of injury rehabilitation
use of cooling to treat injuries. quicker alternative to ice baths
explain how injuries such a muscle strains are treated
with RICE
this involves applying ice to limit pain and reduce swelling by decreasing blood flow to the injured area
what is the physiological explanation as to why cryotherapy is a method of injury rehab
- whole body cryotherapy involves the use of cryogenic chambers to reduce pain and inflammation
- the chamber is cooled by liquid nitrogen to a temperature below -100 degrees and the athlete remains in the chamber wearing gloves & socks & swimming costume for up to 3 minutes
- the freezing gas surrounds the body so that the blood from the arms and legs flows towards the core in an attempt to keep the body warm and protect vital organs from the extreme cold
- on leaving the chamber, the blood returns back to the arms and legs rich in oxygen which helps heal injured cells
define heat therapy
applying heat to an area before training for therapeutic effect such an increased blood flow
describe the aim of heat therapy
to reduce muscle tension, stiffness and pain
explain the aim of heat therapy
- causes vasodilation and increases blood flow to help assist healing injuries around 48 hours post injury and during rehabilitation
- may include heat packs, hot towels, heat rubs and warm water immersion for up to 20 mins
- not to be used for acute phase as it will increase swelling
define contrast therapy
the use of alternate cold and heat for therapeutic effect such as increased blood flow
when should contrast therapy be used after injury
3-5 days post injury after the acute phase
describe the common approach to contrast therapy
- immerse body up to shoulder level post exercise
- use cold water followed immediately by warm water
- have a coke to warm water ratio of 1:3 or 1:4 mins
- have an accumulation of 6-10 mins in cold water
- this causes vasoconstriction followed immediately by vasodilation causing a pumping action to heal damaged tissues
what are the benefits of heat therapy
- vasodilation of blood vessels increasing blood flow
- decreasing muscle tension, stiffness and pain
what are the risks of heat therapy
increased swelling and pain after acute injury
what injuries is heat therapy used for
chronic injuries and late stage acute injuries before exercise
what are the benefits of cold therapy
vasoconstriction og blood vessels decsreasing blood flow, swelling and pain
whar are the risks of cold therapy

skin abrasions if direct contact between ice and skin
for what injuries is cold therapy used for
acute injuries and after exercise to relieve symptoms of exercise induced muscle damage
what are the benefits of contrast therpay
large increases in blood flow and nutrient delivery to damaged tissue
decreased swelling and pain
what are th erisks of contrast therapy
limited benefit over and above cold therapy
for what injuries is constrast therapy used for
acute injuries after bleeding and inflammation have stopped and to relieve symptoms of exercise induced muscle soreness
describe the 3 phases of physiontherapy
- fisrt phase = pain relief, minimise swelling, ice therapy and shoulder sling for support
- second phase = tailored exercises to maintain rotator cuff muscle strength
- third phase = restore normal range of motion, muscle length, connective tissue mobility and resting muscle tension about the shoulder joint with mobilisation, massage, stretching & possibly acupuncture

- cold therapy like ice packs/ ice baths post-exercise
- massage and stretching techniques
- anti-inflammatory and pain meds
- medical attention if dark urine and heavy swelling as may indicate level of muscle damage has affected the kidneys
