High cholesterol is a dangerous contributor to coronary heart disease. The National Cholesterol Education Program (NCEP) Guidelines from the National Institutes of Health state that a total-cholesterol level of 240 milligrams per deciliter (mg/dl) or higher indicates an elevated risk of having a heart attack. Optimally, LDL, the “bad” cholesterol, should be 100 mg/dl or below for high-risk individuals (those with cardiovascular disease [CVD], diabetes or a 20 percent [%] or greater chance of suffering a heart attack or dying from CVD in the next 10 years).
McCully, K.K., et al. 2004. Muscle metabolism with blood flow restriction in chronic fatigue syndrome. Journal of Applied Physiology, 96, 871-8.
Study. Exercise physiologists at the University of Georgia set out to determine whether chronic fatigue syndrome (CFS) is associated with reductions in blood flow and muscle oxidative metabolism.
Previous research has found that people who have had heart failure can benefit from exercise in hospital-based programs on equipment such as bicycle ergometers. However, Teresita Corvera-Tindel, RN, PhD, and colleagues note that this equipment might not always be available to patients. To see how patients would benefit from home-based walking regimens, they studied the impact of a progressive 12-week program.
Here’s another reason for your clients to maintain a healthy weight: Women who have gained more than 20 pounds since age 18 have a higher risk of developing breast cancer after menopause than women who have maintained their weight, according to research published in the February issue of Cancer Epidemiology Biomarkers and Prevention.
If you train clients with hypertension, you’ll want to check out the new position stand of the American College of Sports Medicine (ACSM) on “Exercise and Hypertension.” (It replaces ACSM’s 1993 position stand “Physical Activity, Physical Fitness, and Hypertension.”) ACSM’s latest stand views exercise as a cornerstone therapy for the primary prevention, treatment and control of the disease.
According to “Boomer Coalition Reality Check: When Boomer Optimism Becomes Denial,” a new survey conducted by RoperASW on behalf of the Boomer Coalition and the American Heart Association, Baby Boomers in the United States are very aware of cardiovascular disease. Unfortunately this knowledge is not spurring them to take action to combat the disease. For example:
Only 47% of survey respondents eat a
healthy diet each day.
Only 55% exercise more than three
times each week.
How many times have you heard clients complain about chronic pain in their wrists or hands when performing a certain exercise? Chances are, a majority of these complaints are coming from people diagnosed with carpal tunnel syndrome (CTS). According to the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health, 3 out of every 10,000 workers lost time from work in 1998 because of CTS (NINDS 2004). Half of these workers missed more than 10 days of work due to the condition.
Bart Staal, J., et al. Graded activity for low-back pain in occupational health care: A randomized, controlled trial. 2004. Annals of Internal Medicine, 140 (2), 77-84.
Background. Low-back pain is a common medical and social problem frequently associated with disability and absence from work. However, data on effective
return to work after interventions for low-back pain are scarce.
Now there’s yet another group that benefits from exercise: people with chronic heart failure. Properly supervised exercise programs improve the survival of this population, according to new research in the January 24, 2004, issue of the British Medical Journal.
