4.2 preparation and training methods Flashcards
Define quantitative data with example
can be written down or measured with numbers e.g. cooper run distance is measured in metres + results compared to a standardised table
Define qualitative data with example
is descriptive and looks at the way people think or feel e.g. Borg scale measures rating of perceived exertion by assigning numbers to how you feel during training
Define objective data with example
based upon facts and is measurable e.g. maximal fitness tests like multi-stage fitness test
Define subjective data with example
based upon personal opinions, assumptions, interpretation and beliefs. involves opinion. e.g. sub-maximal fitness test like harvard step test
Define validity
when the test actually measures what it sets out to do
What 2 questions are important when assessing validity?
1) is the research method relevant and does it do what it sets out to do? e.g. sit and reach test only measures flexibility of hamstrings and lower back so is a valid test for lower body flexibility but not upper body
2) is the test sport-specific?
Define reliability
where the test can be repeated accurately and consistent results are achieved
What needs to be taken into account to ensure a test is reliable?
- tester should be experienced
- equipment should be standardised
- sequencing of tests is important
- repetition of tests to avoid human error
State the physiological effects of a warm-up?
- reduces the possibility of injury by increasing the elasticity of muscle tissue
- the release of adrenaline will increase heart rate and dilate capillaries which allows more oxygen to be delivered to the skeletal muscles
- muscle temperature increases which enables oxygen to dissociate more easily and increases enzyme activity
- an increase in the speed of nerve impulse conduction, allows us to be more alert (improving reaction time)
- efficient movement at joints through increased production of synovial fluid
- allows for rehearsal of movement
- mental rehearsal, stress or anxiety reduction, psychological preparation
- supplies an adequate blood flow to the heart to increase its efficiency
Define active stretching
involves the performer working on one joint, pushing it beyond its point of resistance, lengthening the muscles and connective tissues surrounding it
Define passive stretching
when a stretch occurs with the help of an external force e.g. a partner, a wall or gravity
Define ballistic stretching
involves performing a stretch with swinging or bouncing movements to push a body part even further
Define static stretching
when the muscle is held in a stationary position for 30 seconds or more
What is the first stage of a warm-up?
cardiovascular exercise
What is the purpose of the first stage of the warm-up?
- gently increases heart rate
- which increases cardiac output and breathing rate
- more blood directed to the working muscles through vascular shunt
- which all increases amount of oxygen being delivered to the muscles
