Kine 2P84 Lecture One Jan 9th 2017 Status- physical size, maturation, performance levels Progress- rate of development (height, weight) Comparison and Prediction- abnormalities, interventions Figure out what is wrong (if anything) PhysicalActivity and Performance- trainability (timing of, type of, how to..), attainment of physical performance goals    Examples of PracticalApplications 1. Maturity- Related Behaviors 2. Individualized Development Readiness a. Schools, Teams, Sports 3. Response to Performance Pressure? a. Is the activity in the best interest of the individual? 4. Gender Differences a. Should males and females be competing against each other? When should they separate? 5. Maturation considerations a. What to do about early of late "maturating" children? 6. Nature (Genotype) or Nurture (Phenotype) 7. How are skills developed? a. Stages and/or components? Timing? Sequence? 8. University versus Variability (Key Word in This Course) a. Ethnicity, Obesity, Family.. 9. Safety/Liability Issues 10. Sensitive or Critical Periods a. If something doesn’t happen during this period, its either not going to happen or its not going to come and it will effect us in the long run i. E.g., Osteoporosis (loss of bone mass) - we only gain bone mass in growing years, which is a sensitive period. If we don’t add a lot of bone mass (bad nutrition, no physical activity), you will never catch up when you're older   Common Research Challenges with Children and Youth • Ethical ◦ Consent ◦ Invasive techniques • If you are studying the temperatures and factors that effect heat stroke in children, so you must put children through rough circumstances in order to complete research • Methodological Issues ◦ Maturation effect (Only in Children) • Comparing with age vs comparing body size ◦ Body size ◦ Animal model Kine 2P84 Lecture One Jan 9th 2017 • Sometimes studies can be done on animals (puberty can not be studied on animals) ◦ Motivation, concentration, attention • Children will not be able to sit and pay attention as long as an adult • Study Design ◦ Correlation vs Control • Correlation study: What is the association between body size and muscle strength? • Control Study: What is the difference in bone strength between obese children and average weight? (More powerful) ▪ Normal children is the control group ◦ Cross-sectional vs longitudinal • Cross-sectional Study: If I want to know the change in muscle strength as children (age 6-17) grow (faster, not as costly,
