  2. The Scientific Method: The Steps

  3. Making Observations Kinesiology is the academic discipline which involves the study of physical activity and itsimpact on health, human performance, society, and quality of life.

  4. Making Observations • Adopting a crouched position when cycling allows me to complete a 30 mile ride faster (Biomechanics) • I have heard that if I take certain supplements I will recover from a bout of physical activity faster (Physiology) • When I’m stressed my performance suffers (Psychology) • My child seems to be a lot more clumsy than he used to be (Development) • My friend has far fewer lapses of memory than me (Fitness and Health)

  5. Asking a Question: Defining the Problem When I take certain supplements I recover from a bout of physical activity faster • What supplements? Creatine • When are they taken? Before, during, or after? Before • What sort of physical activity? High intensity but for a short time Will taking a month-long regime of creatine help with recovery from repeated bouts of short duration, high intensity physical activity?

  6. Forming the hypothesis: Anticipating Outcomes The “Null” Hypothesis A statement of no difference

  7. Forming the NULL Hypothesis: Taking a month-long regime of creatinewill have no impact on recovery from repeated bouts of short duration, high intensity physical activity?

  8. Forming the hypothesis: Anticipating Outcomes #1 Experimental Hypothesis: Non Directional Statement of difference(s) #2 Experimental Hypothesis: Directional Statement of specific difference(s)

  9. Forming Experimental Hypotheses: Taking a month-long regime of creatinewill influence recovery from repeated bouts of short duration, high intensity physical activity? Taking a month-long regime of creatinewill shorten recovery from repeated bouts of short duration, high intensity physical activity?

  10. Conducting an Experiment: Getting the Answers Will taking a month-long regime of creatinehelp with recovery from repeated bouts of short duration, high intensity physical activity? • Independent Variable: Creatine or No Creatine • Dependent Variable: Estimate of Recovery

  11. Organizing the Data: Descriptive Statistics #1 Organize or Sort Categorize, Rank, etc #2 Estimate central tendency Mean, Median, Mode #3 Estimate variability Range, Variance, Standard Deviation

  12. Organizing the Data: Descriptive Statistics #1 Correlation relationships or associations #2 Regression prediction #3 T-tests and/or ANOVA Tests of difference

  13. How are these data used?Presenting findings

  14. Communicating Findings #1 Journal Article #2 Verbal Presentation #3 Posters

  15. Ways these findings may be used ? #1Impetus for research #2Basis for rehabilitation protocols #3Background for equipment design #4 Rationale for Policy Change
