Quantitative data definition-
Data containing numerical information
Qualitative data definition-
Non numerical data that looks at feelings, opinions and/or emotions
Subjective data definition-
Information based upon personal opinions, assumptions, interpretations and/or beliefs
Objective data definition-
Information based upon facts and is measurable
Validity definition-
When a test measures what it claims to measure
Reliability definition-
Test results are consistent when repeated and outcomes of the test stay the same
What must be taken into account to ensure reliability?
-The tester should be experienced
-The equipment should be standardised
-The motivation of the participant
-Tests should be repeated to avoid human error
Why should we warm up?
-For physical and mental readiness
-To reduce the risk of injury
What are the three stages of a warm up?
-Cardiovascular exercise (pulse raiser)
-Stretching
-Sport-specific movement patterns
Effects of a pulse raiser on the body-
-Gently increases heart rate
-Increases cardiac output (HR x SV)
-Increases breathing rate
-Directs more blood to working muscles (vascular shunt)
Ultimate aim of a pulse raiser-
To increase the volume of oxygen being delivered to the muscles
Static stretching definition-
Stretching while not moving - can be active or passive
Ballistic stretching definition-
Stretching with swinging or bouncing movements to push the body part even further
Effects of stretching during warm up on the body-
-Increases range of motion at the joints
-Increases the ease with which muscles can be extended
-Reduces risk of injury
Physiological effects of a warm up-
-Reduces possibility of injury
-Increased heart rate and increased oxygen transported to correct parts of body
-Efficient movement at joints through production of synovial fluid
-Increased muscle temperature
-Increase in the speed of nerve impulse conduction
-Psychological preparation e.g. mental rehearsal
How does warming up reduce the possibility of injury?
It increases the elasticity of muscle tissue
Effect on body of muscle temperature increasing during a warm up-
It enables oxygen to dissociate more easily from haemoglobin and allows for an increase in enzyme activity which makes energy readily available through better chemical reactions
Effect on performance of an increase in the speed of nerve impulse conduction during a warm up-
It allows us to be more alert which improves reaction time
What does a cool down involve?
Some form of light exercise
Purpose of a cool down in relation to lactic acid removal-
It keeps the heart rate elevated, in order to keep blood flow high and allow oxygen to be flushed through the muscles. This removes and oxidises any lactic acid that remains
Purpose of a cool down in relation to the skeletal muscle pump-
It allows the skeletal muscle pump to keep working which maintains venous return and prevents blood from pooling in the veins
Effects of blood pooling-
Fainting, dizziness and occasionally a loss of consciousness
Purpose of a cool down in relation to DOMS-
Can limit the effect of DOMS
What is DOMS and what are the characteristics of it?
Delayed Onset of Muscle Soreness- characterized by tender and painful muscles often experienced 24-48 hours after heavy exercise
