π’ 4.2 Preperation & Training Method in Relation to Maintaining Physical Activity & Performance Flashcards
(51 cards)
What is quantitive data
Factual information and numerical data
What is qualitive data
Subjective data, looks at feelings, opinions and emotions
What is rating perceived exertion (RPE)
Simply giving an opinion about how hard you feel your body is working during exercise
What is the Borg scale used for
Use the Borg scale to assign numbers to how you feel your level is intensity is during training
What is objective data
Data based upon facts
Example of an objective measurement
The wingate test, used to measure anaerobic power where a performer cycles as fast as possible for 30 seconds on a cycle ergometer, resistance applied. A counter is used to count how many times the flywheel completes one full turn in 5 second intervals.
What is subjective data
Data based upon personal opinions, assumptions, interpretations and beliefs.
What is validity
When the test actually measures what it sets out to
To assess the validity, what 2 questions are important
- is the research method relevant and does it do exactly what it sets out to?
- is the test sport specific?
What is reliability
Means the test can be repeated accurately
To ensure a test is reliable what needs to be taken into account
- tester should be experienced
- equipment should be standardised
- sequencing of tests is important
- repetition to avoid human error
What is the first stage of a warm up and what is its effect
To perform some kind of cardiovascular exercise such as jogging. This will gently increase your heart rate, increasing cardiac output and through vascular shunt, more blood directed to working muscles.
What is the second stage of a warm up
Stretching / flexibility exercises
2 types of static stretching
Active
Passive
What is static stretching
Stretching whilst not moving
What is active stretching
The performer working on one joint, pushing it beyond its point of resistance, lengthening the muscle and connective tissue surrounding it
What is passive stretching
When stretching occurs with the help of an external force, e.g partner or gravity or wall
What is ballistic stretching
Performing a stretch with swinging or bouncing movements to push a body part even further
What is the third stage of a warm up
Should involve movement patterns that are to be carried out, e.g shooting in basketball or netball
4 physiological effects of a warm up
- reduces possibility of an injury by increasing the elasticity of the muscle tissue
- release of adrenaline will increase HR and dilate capillaries allowing more oxygen to muscles
- muscle temperature increases this will enable oxygen to dissociate easier from haemoglobin and also allow increase enzyme activity
- increase speed of nerve impulse conduction allowing us to be more alert, improve reaction time
What is a cool down
Takes place at the end of exercise and consists of some form of light exercise to keep the heart rate elevated
Physiological Effects of a cool down
- allows oxygen to be flushed through the muscle, removing and oxidising any lactic acid that remains
- allows skeletal muscle pump to keep working, which maintains venous return and prevents blood from pooling in the veins. This could cause fainting, dizziness and occasionally loss of consiousness
- limits effects of DOMS which occurs from a structural damage to muscle fibres and connective tissue surrounding the muscle fibres
What are the principles of training
Specificity
Progressive overload
Reversibility
Recovery
SPORR
What is specificity
Making sure the training you do is relevant for your chosen activity, have to consider whether you are using the same energy system, muscle fibres, skills and movements
