What Effects Does Weight Training Have on Heart Disease?
Healthy Heart Tissue
Weight training is important for cardiac health because heart disease risk
is lower when the body is leaner. One study found that cardiac patients gained
not only strength and flexibility but also aerobic capacity when they did
weight training three times a week as part of their rehabilitation program.
This and other studies have prompted the American Heart Association to recommend
weight training as a way to reduce risk of heart disease and as a therapy for
patients in cardiac rehabilitation programs.
Research and Background About Weight Training
Scientific research has shown that exercise can slow the physiological aging
clock. While aerobic exercise, such as walking, jogging, or swimming, has many
excellent health benefits—it maintains the heart and lungs and increases
cardiovascular fitness and endurance—it does not make your muscles strong.
Weight training does. Studies have shown that lifting weights two or three
times a week increases strength by building muscle mass and bone
density.One 12-month study conducted on postmenopausal women at Tufts
University demonstrated 1% gains in hip and spine bone density, 75% increases in
strength and 13% increases in dynamic balance with just two days per week of
progressive weight training. The control group had losses in bone, strength,
and balance. Weight training programs can also have a profound effect on
reducing risk for falls, which translates to fewer fractures.
