Test 3 Flashcards
What is agility?
A rapid whole body movement with change of velocity or direction in response to a stimulus
How is agility related to SPEED factors?
A distinct physical quality compared to agility
How is agility related to STRENGTH factors?
Leg strength, bilateral reactive strength, unilateral muscle strength
How is agility related to COGNITIVE factors?
Ability to use cues earlier in skill execution to anticipate opponent’s movement
505 Test (Agility)
(+): most valid test, highest correlation in turning phase (-): did not correlate highly with velocity, requires expensive equipment, no stimulus present
Illinois Agility Test (Agility)
(+): considered standard test, correlated strongly with top speed, doesn’t require expensive equipment (-): less valid than 505 test, no stimulus present
Reactive Agility Test (Agility)
(+): stimulus present, able to test cognitive aspect (-): sport-specific, expensive equipment, stimulus displayed in a 2D format
Basic idea of Illinois Agility Test
Navigate a course as quickly as possible that requires an individual to make sharp turns and weave
What has to be considered to produce valid and reliable test results for the Illinois Agility Test?
Validity: monitors the effect of training on an athlete’s physical development Reliability: dependent on how strict test is conducted and individual’s level of motivation
What is health-related quality of life?
A multi-dimensional concept that includes domains related to physical, emotional, and social functions; focuses on the impact health has on quality of life
How can health-related quality of life be assessed?
The Healthy Days Measures Short Form-36
Scales of the SF-36
Vitality Physical functioning Bodily pain General health precautions Physical role functioning Emotional role functioning Social role functioning Mental health
How is the SF-36 administered and what must be considered during the scoring process?
Patient-reported survey Items are scored so that a high score defines a more favorable health state
What is salutogenesis?
A stress resource orientated concept which focuses on resources that maintains and improves the movement towards health
What is the background of salutogenesis?
Antonovsky: found how specific personal dispositions serve to make individuals more resilient to the stressors of daily life Characteristics that help an individual cope and remain healthy (GRR & SOC)
What is the ease-disease continuum?
A stressor causes a state of tension, which can either be pathogenic or have neutral or even healthy consequences
What role does the ease-disease continuum play withing salutogenesis?
How we react to the stressor through our GRRs determines our SOC and resilience
What generates health in light of the salutogenic theory?
Generalized resistance resources (GRRs)
What is the sense of coherence?
When a person has a pervasive, enduring though dynamic, feeling of confidence that one’s environment is predictable and that everything will work out as well as can reasonably be expected
How is the SOC-Score calculated?
Calculated using three components - comprehensibility, manageability, and meaningfulness
What is represneted by higher or lower SOC-scores?
Higher = better Lower = worse
What is the basic idea of linear correlation?
The degree to which a straight line best describes the relationship between two variables
Examples of linear correlation
- Athletic participation & academic achievement - High level of fitness & earning higher academic grades
What is a scatter diagram?
Used to determine correlation of data
How to interpret a scatter diagram
Positive: data heights increase Negative: data heights decrease No correlation: no relationship between variables
What statistical measure for linear correlation are available?
- Spearman Rank-Difference Correlation Coefficient - Pearson Product-Moment Correlation Coefficient
What to consider when interpreting correlation
- Do it with caution - High correlation doesn’t indicate that one variable causes something to happen to another - Purpose of correlation must be considered
What is the basic idea of a t-test?
Used when an individual seeks to determine the difference in performance and results of various groups
Examples of when t-tests are used
- Males vs. females - Athletes vs. non-athletes - Smokers vs. non-smokers
What is the idea of a t-test for independent groups?
Comes from the same population or background; used to determine the significance between two independent result averages
What is the idea of a t-test for dependent groups?
Random sample from a normal population
What are the differences between these two approaches?
Compares only one test instead of two, eliminating the need for the equal variances assumption
