2. Outline
• Physical health and cognition
• how exercise improve general health?
• physical health vs. brain health
• Sport and cognition (coming soon)
• can elite athletes show superiority in
cognitive processing?
• Inside the brain of athletes

5. Definitions of physical-health-related factors
• Fitness
• A general state of good health, usually as a result of exercise
and nutrition
• subcomponents of physical fitness: muscle, cardiovascular..
• Physical activity
• Any bodily movement produced by skeletal muscles that
requires any energy expenditure
• Physical inactivity is the 4th leading risk factor of global
mortality

6. Why this issue is important?
Wen et al., 2011, The Lancet
The relationship between physical activity volume and mortality reduction compared with
individuals in the inactive group
A prospective cohort study with 416175 individuals from 1996 to 2008 in Taiwan

14. Active lifestyle vs. reaction times in elderly adults
• Reaction time (RT) tasks have often been used to
assess cognitive performance in adult adults
Spirduso, 1975, J. Gerontol.

performance

32. Interesting problems in Taiwan

33. WHO 2011 recommendations of physical activity
• Children aged 5 - 17 years
• 60 minutes of moderate-to-vigorous-intensity
• 3 times per week
• aerobic activities or those help strengthen muscle and bone
• Adults aged 18 - 64 years
• at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity
• at least 2 days/week of muscle-strengthening activities involving major muscle groups
• Older adults aged 65 and above
• at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity
• at least 3 times/week of physical activity with balance improvement
• at least 3 muscle-strengthening activities involving major muscle groups
• As could as possible

34. Take home messages
• Exercise may help maintain or improve brain
functions in elderly adults
• Children with higher levels of fitness may have
greater cognitive functions and better academic
achievement
• Why you sit here??
