Exercise as it relates to Disease/Effects of exercise on cognitive abilities in elderly populations
The Effects of Exercise on Cognitive Abilities in Elderly Populations[edit | edit source]
Background[edit | edit source]
Although the decline in cognitive abilities as we age is widely variable, in general our cognitive abilities do decline in older populations.[1] Studies into the effects that exercise can have on this decline have been produced for decades [2] and have produced a wealth of knowledge on the subject. Exercise has been shown to positively effect the cognition of elderly adults (Adults of 60+ years and those with degenerative diseases of 50–60 years).
The Effects Exercise has on Cognitive Ability[edit | edit source]
Apart from the obvious benefits to the physical capabilities through increased fitness and physical function,[3] exercise has long been shown to have a positive effect on cognition. Activities such as aerobic fitness training can have a “robust and beneficial influence on the cognition of sedentary older adults”[4] (although this adaptation can be fairly specific). Not only has it been shown improve cognitive function but also decrease cognitive decline [5] and incidences of degenerative diseases such as Alzheimer’s [6][7]
Recommendations[edit | edit source]
Recommendations for exercise in elderly populations (specific for improving cognition) align with those of the American College of Sports Medicine and the American Heart Association of:
Aerobic activity[edit | edit source]
Moderate-intensity 30 mins 5 days pw Vigorous-intensity 20 mins 3 days per week
Muscle Strengthening Activity[edit | edit source]
8-10 exercises on 2 or more non consecutive days per week using the major muscle groups
Benefits of Greater Amounts of Activity[edit | edit source]
Participation in exercise above the recommended Aerobic and Muscle Strengthing activity has increased benefits
Flexibility Activity[edit | edit source]
10 mins at least 2 days per week
Balance Activity[edit | edit source]
Some balancing activity should be included
