New advice suggests that persons with cardiovascular conditions and those who do not regularly exercise may risk cardiovascular events during intense exercise.

People who have not exercised in a while should start with light walking, the new statement suggests.

Announcement from the American Heart Association (AHA) reports that people who do not workout frequently and with heart disease may be at higher risk for cardiovascular events in intense exercise.

They also suggest that people with sedentary lifestyles should develop and develop gradual exercise regimes.

It is also important to talk to a doctor before beginning a workout– regardless of its intensity.

The statement states that the increased awareness of the health benefits of exercise has led many to become more healthy. Nevertheless, the number of people who are engaged in high intensity training has risen too, for which their bodies may not be prepared.

The benefits of exercise

Studies have shown that physical activity is of great importance in a healthy life. Exercise has a range of benefits, including a reduction of the risk of major physical health problems and mental health Benefits.

In particular, an article in the European Preventive Cardiology Journal indicates that physical activity will reduce the risk of cardiovascular mortality by 35% and death by 33% in general.

An article in the British Journal of Pharmacology suggests that “exercise is so successful that it is a medicine.”

The authors of the new scientific declaration point out the fact that much more people practice because this research has become widely understood and accepted.

This also includes an increase in people who practice more intensively.

“Worldwide involvement in endurance training, competitive long-durance events and high-intensity interval training have significantly increased as the previous[ AHA] statement on exercise risk” says the authors.

The risks associated with exercise

Although exercising provides several health benefits, other groups of people may also be at risk from exercise.

“Exercise is medicine, and there can be no doubt that moderate to vigorous physical activity is beneficial to overall cardiovascular health,” says Prof. Barry A. Franklin, Chair of the New State Writing Committee, and Professor of physiology at Wayne State University, Detroit, MI.

“However, like medicine, it is possible to underdose and overdose on exercise — more is not always better and can lead to cardiac events, particularly when performed by inactive, unfit, individuals with known or undiagnosed heart disease.”

– Prof. Barry A. Franklin

In particular, high intensity exercise can be especially taxing on a person’s cardiovascular system.

“Many people run marathons, take part in triathlons and train at high intensity intervals. This declaration seeks to bring these vigorous activities[ in] context on the benefits and risks,” states Prof. Franklin.

More than 300 studies were taken into account in making their findings in the revised scientific statement. This shows that more practice is required for the vast majority of people. The benefits outweigh the disadvantages very much.

But suddenly performing significantly stronger exercise may increase the risk of cardiovascular events, such as heart attacks, for those people that are not physically active and those who have underlying medical conditions.

In its review of the literature, for example, the authors found that nearly 40% of the cardiovascular events first-time participants in triathlons showed the potential for poor training that increases the risk of adverse events.

Start slow and build up

As they find that people who wish to raise their level of physical activity should begin with an simple exercise scheme and over time increase their quantity and intensity.

Professor Franklin said: “It’s important to begin the exercise, but to go slowly, even in high school if you are an athlete.”

For example, if you do very little physical activity, you might start by walking regularly. If it is hard, then they can try to walk uphill regularly, and then jog gently.

The writers also recommend that before beginning any new exercise routine, if a person has a heart condition, they should consult with a doctor.

Despite the potential risks outlined in the sentence, it should not be taken by people to suggest that exercise of high intensity should be avoided. Further activity is good for the vast majority of people, and doing so in a controlled manner that increases the duration is low risk.

As the authors of the statement claim, “the benefits of long-term exercise training outweigh the risks to the majority of the population.”
