Australian scientists debunk the myth about heart damage from training
As reported by TUT.AZ, researchers from the Victor Chang Cardiac Research Institute in Australia have proven that physical exercise not only doesn't harm the heart but significantly strengthens it. The results of the work were published in the scientific journal JACC: Advances.
Scientists have dispelled the popular misconception that increased heart rate during sports contributes to the "wear and tear" of the heart muscle. The study showed the opposite: people who regularly engage in physical exercise have a resting heart rate approximately 10% lower than those leading a sedentary lifestyle.
The research data demonstrate a significant difference: physically active participants had a resting heart rate of about 68 beats per minute, while less active people had rates reaching 76 beats. As a result, a trained person's heart makes approximately 11,500 fewer beats per day. For reference: the normal resting pulse for healthy adults is considered to be in the range of 60 to 100 beats per minute.
Professor La Gerche, who led the study, emphasized that a low resting heart rate is an important indicator of good physical fitness and long-term health.
"Despite the fact that during physical exercise the heart works more intensively, the reduced pulse at rest completely compensates for this increased activity," the scientist explained.
