Aerobic Exercise May Protect Against Dementia

Aerobic exercise may help improve memory and thinking skills among older adults with mild cognitive impairment (MCI). In this study, researchers found that seniors who performed aerobic workouts four times a week for six months had a greater increase in brain volume than participants in a control group who did not exercise. The exercise group also showed significant improvement in thinking and memory. Study co-author Dr. Jeongchul Kim comments, “Any type of exercise can be beneficial. If possible, aerobic activity may create potential benefits for higher cognitive functioning.”

Benefits of HIIT

High-intensity interval training (HIIT) consists of short bursts of vigorous exercise with periods of rest. The American Council on Exercise says HIIT offers the following benefits: a major boost to anaerobic and aerobic fitness, increases sensitivity to insulin and lowers levels of fasting insulin, helps decrease percent body fat, and it can help exercisers achieve significant results in less time.

Just Walk

Walking is an inexpensive and simple exercise that has been shown to offer numerous health benefits for bones, muscles, and joints. Dr. Carolyn Hettrich, a spokesperson for the American Academy of Orthopaedic Surgeons reports, “Sometimes the hardest part of working out is getting started… Walking requires minimal preparation, but yields significant benefits. Establish a routine by incorporating at least 30 minutes a day for five days a week.” American Academy of Orthopaedic Surgeons, June 2016

Being Physically Fit Reduces Depression Risk After Heart Attack

People who are physically fit may be less likely to become depressed after a heart attack. Researchers looked at 189 middle-aged and older Norwegians and found that those who exercised regularly in the years preceding their heart attack were less than half as likely to become depressed after a myocardial infarction than those who rarely or never exercised. The findings are important as heart attack survivors are three time more likely to have depression. Though the study did not prove cause and effect, it certainly appears that exercise protects against depression after a heart attack.

Daily Moderate Exercise Reduces Disability Risk in Seniors

Daily moderate exercise can mean the difference between becoming housebound or keeping up with everyday activities later in life. Researchers found that daily moderate exercise among participants ages 70 to 89 reduced loss of mobility by 28% and increased walking ability by 18%. The exercise involved walking 150 minutes a week as well as strength, flexibility, and balance training. Co-principal investigator Dr. Jack Guralnik adds, “The very purpose of the study is to provide definitive evidence that physical activity can truly improve the independence of older adults.”
