If doctors could give you just one piece of advice about what is best for your heart, they would say: Be active. That’s because regular exercise can correct more wrongs, and it can do so better than any other heart-smart pursuit. For women who have had a heart attack, being physically active has special significance. It counts big time in reducing their risk of having another one.
No matter what your size, shape, weight, or age, the health of your heart is strongly dependent on how active you are. “If you want a healthy heart, there is nothing more powerful than being physically fit”.
On the other hand, the consequences of being inactive are major. A sedentary lifestyle is just as bad for the heart as smoking or having high cholesterol or high blood pressure, according to the American Heart Association. Research on women indicates that physical inactivity may even be a bigger risk for a heart attack than obesity.
These are ominous facts when you consider that 70 percent of American women do not exercise regularly, and 41 percent report, they are not active at all. Even more distressing to doctors is research showing that the number of women who exercise regularly is going down instead of going up. That’s because they know that physical fitness can be a life-saver.
This was demonstrated recently by researchers at Johns Hopkins University in Baltimore that measured the fitness levels of 3,000 women ages 30 to 80 and followed their heart health for an average of 20 years. Overall, those whose physical fitness was below average were 3½ times more likely to die of heart disease than the women who scored above average. But another finding is what really set off alarms: Women who had below-average fitness, but were considered at low risk for heart disease, where 13 times more likely to die of heart disease than women who scored above average for fitness. Overall, the death rate increased as fitness levels decreased.
The researchers considered two measurements as the key: The amount of physical activity the women could sustain safely, based on a standard treadmill test, and the amount of time it took their heart rates to return to normal.
The treadmill test is significant because nearly two-thirds of women who succumb to a sudden death heart attack have had no previous heart-related symptoms, reported the research team. Furthermore, the study suggests that women may benefit from higher fitness levels even without positive changes in weight or blood pressure and cholesterol levels.
Inactivity: A Teen Trend
Statistics show that only 52 percent of high-school girls are enrolled in physical education classes and only half of them attend fitness classes daily. Among pre-teens, 61.5 percent does not participate in any organized after-school or weekend physical activity.
By the time a girl reaches age 16 or 17, 31 percent of white and 56 percent of black teenagers do not participate in any kind of after-school physical activities. The American Heart Association notes the parallel between these statistics and the rise in overweight and increase in smoking among teen girls.
