Transcript of Optimal Aging Through Fitness

"Improving one's physical fitness can reduce the risk of death by 44%" (Blair et al 1995)
Having a higher level of physical fitness can promote a better view on self image, esteem, and depression (Kirkealdy et al 2002; Strawbridge et al 2002; Goodwin 2003)

Prescribing Exercise
-Elderly people who exercise are less likely to be diagnosed with dementia
-recommended 75 min of vigorous physical activity throughout the week
-also 20-30min of moderate intensity almost every day has a positive result of physical function
-Decline in muscle mass 1-2% each year after 50
-more likely to continue exercising in old age if active throughout life
-middle-age adults give up sports and leisure activities because of job/family

Benefits of fitness
Physical fitness can predict both cardiovascular and all-cause mortality
-aerobic capacity, strength, speed, agility, coordination, flexibility
Exercise is the best way to delay and prevent the negative effects of aging while also improving health
Physical Activity: body movement made by muscle action which increases energy expenditure
Exercise: planned, structured, repetitive, purposeful physical activity
Physical Fitness: capacity to perform physical exercise
Having strong muscle tone is another way to prevent dying
-reduce risk of falling
-What other ways could it help?
Anti-Aging Therapy Through Fitness Enhancement
-increase daily physical activity
-do not over train (why?)
-aerobic exercise like walking helps cardiovascular health
-3 to 5 days per week
-dynamic exercise: mimic every day activities and done at controlled speed with normal breathing pattern
-88 healthy low-active older adults
-Disruption of axons and myelin in WM is one of the primary reasons for age-related cognitive decline
-maintaining WM structural connectivity can help preserve brain function and increase ability to live independently throughout old age

-structured exercise and light PA linked to greater WM integrity in temporal regions, which are prone to age-related changes
-Low-active adults showed to have negative impacts on the hippocampus which is responsible for learning and memory processing
-increasing PA = beneficial brain health
