Heart rate responses to resistance exercise have been more widely reported than changes in stroke volume and cardiac output. The small-to-modest increase in cardiac output during resistance exercise is the result of a modest increase in heart rate and an unchanged or decreased stroke volume. During resistance exercise, heart rate increases modestly but stroke volume decreases; thus cardiac output is only modestly increased.
Dr. Steven N. Blair investigates the health risks associated with physical inactivity and discusses effective, proven methods you can take to encourage people to start—and keep —moving.

The Campaign for Tobacco-Free Kids, American Heart Association, American Cancer Society Cancer Action Network, American Lung Association, and the Robert Wood Johnson Foundation recently released a report titled "A Broken Promise to Our Children: The 1998 Tobacco Settlement 11 Years Later". The states this year (Fiscal Year 2010) will collect $25.1 billion in revenue from the tobacco settlement and tobacco taxes, but will spend barely 2 percent of it—$567.5 million—on tobacco prevention and ...
Blood pressure is reported as two distinct numbers: systolic blood pressure (top number) and diastolic blood pressure (bottom number). The pressure in the blood vessels during the heart’s contraction phase is called systolic blood pressure, and the pressure during the relaxation phase is called diastolic blood pressure. Risk begins to increase once resting systolic blood pressure exceeds 115 mmHg and diastolic blood pressure exceeds 75 mmHg.
The AHA strongly recommends that a physician, licensed to practice medicine in the community in which the health/fitness facility is located, should provide the oversight of the facility’s emergency response system and AEDs. Likewise, orientation of new facility members might include a simple printed information card indicating the location of pertinent emergency response postings in the facility; the locations of the emergency telephone and AED; which staff members may need to be employed ...
The Exercise/Physical Activity and Screening for You (the EASY) can be used independently by older individuals or completed with their health care providers. There is now substantial evidence documenting the many health benefits associated with physical activity for adults of all ages (Netz et al. Physical activity improves health even for chronically ill or frail older adults for whom it is often falsely believed that physical activity will exacerbate versus ameliorate underlying health ...
