Operation 2: Peacock Flashcards
(33 cards)
Define both quantitive and qualitative data
Quantitive- can be written down or measured with numbers e.g 12 minute cooper run
Qualitative - subjective, looks at feelings, emotions and opinions. E.g Borg scale method of rating perceived exertion - performers intensity level
Define and compare objective and subjective data
Objective - involves facts and is measurable, bleep test measures stamina
Subjective data - data based upon personal opinions, assumptions, interpretation e.g sub maximal test of Harvard step test
Define and discuss validity and reliability
Validity -when the test actually measures what it sets out to do, is the research method relevant, is the test sports specific
Reliability -means the test can be repeated accurately, consistent and same outcome - tester should be experienced,equipment should be standardised, sequencing of test is important
What is proprioceptive training
Proprioception is subconscious process using a system of receptor nerves located in the muscle joints and tendons. Smooth co ordinated movements, brain needs accurate knowledge of arm and leg position
Uses hopping, jumping and balance exercise to restore lost proprioception
What are some example of strength training
Free weights- dumb bells, kettlebells, muscles have to stabilises the weight
Machine weights - machine has lots of control, early stages of an injury
Body - involves core exercise, body is resistance, helps balance posture
Therabands - latex and different strengths
Explain hyperbaric chambers
Chamber pressurised and 100% oxygen , more oxygen can be inspired, excess oxygen dissolve into the blood plasma, reduce swelling and both stimulate WBC activity
Define, explain and give examples of cryotherapy in both injury rehab and exercise
Cryotherapy - use of cooling to treat injuries, RICE, limit pain and swelling and decreasing blood flow
Ice bath - vasoconstriction, drains blood out of legs , new blood that invigorates the muscle with oxygen to help the cells function better
Discuss injury prevention methods
Screening - identify those at risk of complications from exercise, enhance performance, reduce injury, muscoskeletal ,ROJM,muscle imbalances
ECG- used to assess and monitor a performers heart
Protective equipment
Warm up
Flexibility,active -stretched position is held by the contraction of an agonist muscle, passive - uses an external force to help stretched position,static - muscle held in a stationary position 10, ballistic - swinging and bouncing movement
Taping and bracing - taping weak joint support and stability, bracing often involving hinged supports
Outline some recovery methods - compression garments,massage, foam rollers and sleep and nutrition
Compression garments - improve blood circulation, prevent medial problems - DVT, blood lactate removal, reduce symptoms of DOMS
Massage - prevent and relive soft tissue injuries,
Foam rollers - release tension between muscles and fascia
Sleep - non REM deep sleep, blood flow is directed away
Nutrition - replenishment of glycogen stores
Outline fluid mechanics and dynamic fluid force
Fluid mechanics is the study of an object or the human body that travels through any liquid or gas, swimmer through water
Dynamic -study of how forces affect them, drag and lift
Drag - slows something down, surface drag - friction between the surface of an object and the fluid environment ‘skin drag’ special clothing to reduce
Form drag - impact of the fluid environment on an object, shape drag, relates to streamlining
What factors reduce and increase drag
Velocity of moving body - greater the velocity through a fluid, greater the drag force
Cross sectional area of the moving body - large CSA increases drag
Shape and surface characteristics of a moving body - more streamlined, aerodynamic shape reduces drag . Cyclist with ridges and aerodynamic Helmet with air ducts
Define Bernoulli’s principle
Where air molecules exert less pressure the faster they travel and more pressure when they travel
Apply Bernoulli’s principle to a discs being thrown
Discuss (projectile) act as an aerofoil object , angle of attack is important
Top of discuss travel a longer distance than air underneath, faster velocity , lower pressure
Air above discus travels faster velocity, creates low pressure, upward lift force
created,stays longer
Optimum angle 25 and 40
Apply Bernoulli’s principle to describe downward lift force
Required In speed skiers, cyclist and racing cars
Needs to be pushed down so greater frictional force created
F1, spoiler is angled so lift force act in downward action, air above shorter distance - higher pressure and slower velocity
Define projectile motion and horizontal displacement
Movement of either an object or the human body as they travel through the air
HD- shortest distance from starting to finish point in a line parallel to the ground
What are the factors affecting horizontal displacement
Angle of release - dependent upon release and landing height ,when both release and landing heigh are equal - optimum: 45* , release heigh below landing heigh, greater than 45
Speed of release - greater release velocity of projectile, greater horizontal displacement travelled
Height of release - Greater release height, increase in horizontal displacement
Define and explain factors afferent flight paths of different projectiles
Weight and air resistance affect projectiles while they are in the air
Parabola - curve with matching left and right hand sides
What are horizontal and vertical component
Horizontal motion of an object
Upward motion of an object
Explain how training can adjust the recruitment of different fibre types
Low intensity endurance training will result in recruitment of different slow twitch muscle fibres
High intensity training e.g sprinting will recruit more type 2x fibres
High intensity training will increase the rate of fibre recruitment
Muscles gets stronger, fewer fibres see required to produce the force needed
Define 4 over use injuries
Strain - muscle tear
Tennis elbow - inflammation of the tendons
Stress fracture - fracture of the bone caused by repeated stress
Shin splints - ache or pain across chin bone from repeated stress of bones, muscles, joints
Summaries the advantages and disadvantages of cryotherapy for injury rehab
Adv- pain relief, reduced inflammation, muscle healing
Disadvantages- accessibility to resources, cost, skim damage, discomfort
Assess the factors affecting the movement of swimmer through water
Technique
Fluid friction
Level of fitness
Gravitational pull v buoyancy
Explain attitude and the Triadic model
Attitude - value aimed at an attitude object
Triadic model - three parts of an attitude: cognitive,affective and behavioural
C- belief
A- relates to feelings and interpretation
B- actions of the performer
Explain learned helplessness and and strategies to avoid it
LH- using internal stable reasons for losing such as ability
Avoid - attribution retraining: changing the reasons for failure, provide motivation via reinforcement, achievable goals, stress any personal improvements made during the game
