When does the body reach its peak strength? A 47-year study reveals the age of peak fitness and beyond

A long-term scientific study lasting 47 years has revealed the age at which a person reaches peak physical fitness, as well as the age at which a gradual decline in physical abilities begins, with results described as encouraging for those who start exercising later in life.

Peak fitness: A defined time window

According to what was reported by the Mirror newspaper, the study's results showed that physical ability and muscle endurance reach their highest levels between the ages of 26 and 36 for both men and women, before beginning a gradual decline after the age of thirty-five.

Inactivity accelerates decline

Researchers noted that individuals who lead a sedentary lifestyle are more likely to experience a noticeable decline in their physical functions after surpassing peak age, compared to those who maintain regular physical activity.

Notable figures on fitness loss

According to scientists at the Karolinska Institute in Sweden, physical ability can decline by as much as 48% between the ages of 35 and 63. This decline begins at a relatively slow pace but accelerates with age, highlighting the importance of continuing physical activity.

Exercise after 35… Positive results

Despite this natural decline, the study carried encouraging news, showing that adults who start exercising after the age of 35 can improve their physical ability by between 5% and 10%, which positively reflects on overall health and quality of life.

Researchers' message: It's not too late

Maria Westerstål, a lecturer in the Department of Laboratory Medicine and the principal author of the study, said: "It is never too late to start moving. Physical activity can slow the decline in physical performance, even if it cannot completely stop it."
