You’ll live longer with some physical activity

By Leave a Comment

Even the simplest physical activity may lengthen lives — no sweating required, new research shows.

In fact, mundane physical activity like household chores may count.Sound too good to be true? That’s the finding from the National Institute on Aging’s Todd Manini, PhD, and colleagues.

“Simply expending energy through any activity may influence survival in older adults,” they write in The Journal of the American Medical Association‘s July 12 issue.

Does their theory hold water? Perhaps, says a journal editorial. Manini’s finding on longevity motion is “provocative and if documented by future research would have major implications for physical activity recommendations,” the editorialists write.

Attention Baby Boomers: Even A Little Exercise Makes A Difference

By Leave a Comment

“What is the most important thing I can do to protect my health/improve my health?”

I’ve been asked this many times and my answer is always the same.

Change your eating habits and get moving.

Article after article points out the power even a little exercise can have on your health!

You don’t need to run a marathon, ride the STP (Seattle-to-Portland bike ride), or spend the majority of every day at the gym in order to see the benefits of exercise.

Yes, we are all busy – but as I remind myself…if I don’t take care of me, what will tomorrow bring?

For further reading, here is a link to the article mentioned above. But when you are done reading…go for that walk!

How To Reduce Your Risk Of Having A Stroke

By Leave a Comment

May is Stroke Awareness Month and the American Heart Association | American Stroke Association has launched new guidelines for stroke prevention.

Here are some things that you can be doing:

  • Get your blood pressure checked. Hypertension (high blood pressure) is a significant risk factor. You can reduce your risk of stokes due to hypertension with proper treatment.
  • Don’t smoke and eliminate your exposure to secondhand smoke.
  • If you have diabetes, it is imperative that you maintain tight control of your blood pressure, as well as your cholesterol.
  • If you already have hypertension reduce you intake of sodium (salt) to no more than 2.3 grams per day and increase your potassium intake to (4.7 gms per day) – eat a diet high in fruit, vegetables, low-fat dairy products and low in saturated and total fat.
  • Lower your total cholesterol to acceptable levels.
  • Be physically active (moderate-intensity) for at least 30 minutes a day. That’s one brisk walk for 30 minutes.

The American Stroke Association recently launched Power To End Stroke, an aggressive education and awareness initiative to reach African Americans, who are at greater stroke risk than other ethnic groups.

Consistent, Moderate Exercise Reduces Women’s Risk of Sudden Cardiac Death

Linda Little, May 9, 2005 (New Orleans)

 Women should exercise more regularly for longer periods of time to reduce the risk of sudden cardiac death (SCD) both overall as well as during exertion, Boston researchers reported here at the Heart Rhythm Society (HRS) 26th annual scientific sessions.

Although they saw a short-term increase in the risk of SCD in women during moderate to vigorous physical activity, the risk lessened in women who reported more weekly exercise, the researchers said.

“Women who exercised regularly had a lower transient risk of [SCD],” said William Whang, MD, a cardiologist at Massachusetts General Hospital and Brigham and Women’s Hospital in Boston, Massachusetts, told Medscape. “For women who exercise, the transient risk was lower in women who exercised two or more hours a week.”

The study was the first to assess both the short- and long-term risks of SCD conferred by exercise among women.

“The important point of this study is that regular exercise can substantially reduce the risk of [SCD],” commented Dwight Reynolds, MD, HRS program chairman and chief of cardiology at the University of Oklahoma Health Science Center in Oklahoma City. “Even if the overall risk is low, if you don’t exercise, then the risk is increased.”

The researchers examined the relationship between self-reported physical activity and SCD in 70,000 women from the Nurses’ Health Study. Information on moderate to vigorous exertion in hours per week were collected during six different years starting in 1986 and ending in 2000. The information was collected via questionnaires and at the time of SCD by reviewing medical records and talking with the next-of-kin.

Women were queried on hours of such exercise as walking, jogging, running, bicycling, lap swimming, and aerobics performed in a week.

Of the almost 70,000 women with no cardiovascular disease or history of stroke, the relative risk for SCD within one hour of moderate to vigorous exertion was 6.2 times that of no exercise in a case crossover analysis, Dr. Whang noted.

Women who exercised fewer than two hours per week had 21 times the risk of SCD during the one-hour period after exercise compared with when they did not exercise. That risk was dramatically reduced in women who exercised regularly, Dr. Whang said. Women who exercised more than two hours a week had three times the risk for SCD in the time period after moderate to vigorous exertion compared with when they did not exercise.

Case crossover analysis estimated the odds ratios for exposure to moderate to vigorous exertion in the hour before SCD. The researchers then determined estimated hazard ratios for the long-term risk of SCD with increasing amount of exertion after adjusting for comorbidities and cardiovascular risk factors.

In a multivariate analysis that adjusted for biologic factors such as body mass index, hypertension, diabetes, and high cholesterol there was a consistent reduction in the risk of SCD with increased hours of exercise per week.

“Increasing amount of regular moderate to vigorous exercise was associated with a lower overall risk of SCD,” Dr. Whang told attendees.

With each increase in the number of hours of moderate to vigorous exercise, there was a relative risk reduction in SCD. For example, women who exercised more than four hours per week had about a 50% reduced risk of SCD. Those who exercised more than seven hours per week had a 66% reduced risk of SCD compared with women who exercised less than one hour.

The relative risk was under one for women exercising more than four hours per week, said Dr. Whang. “It’s consistent with common sense that exercise is associated with benefits in [SCD]; while a transient risk is present, it is very low,” he said. “Women should start off an exercise program slowly and build up. Regular exercise is beneficial.

The study was independently funded. The authors report no pertinent financial conflicts of interest. HRS 26th Annual Scientific Sessions: Abstract 12. Presented May 5, 2005.
