Cardio

Endurance before the word “cardio”

Running, swimming and cycling existed long before these activities were combined under a gym label. They were used to get around, to practice a hobby or to prepare for a competition. The word “cardio” today brings together these practices around a common function: sustainably using the cardiovascular system to improve physical condition.

The popularization of aerobics

Kenneth Cooper played a major role in bringing endurance training to the general public. His book Aerobics, published in 1968, offered an organized way of developing fitness through physical activity. The approach linked regular practice to health and prevention, beyond the sole pursuit of sporting performance.

The creation of the Cooper Institute and the monitoring of populations over time have extended this approach through research. Exercise testing and cardiovascular fitness have become tools to study the link between physical fitness and health. Endurance could thus be presented as a capacity to maintain throughout life, and not just as an athletic quality.

A practice that takes several forms

Cardio therefore does not just mean running on a treadmill. Indoor equipment, group classes and outdoor sports offer different ways to produce this effort. This diversity allows you to choose according to your tastes: the common objective remains regular practice, even if the sensations, the technique and the setting change a lot between a bike and a swimming pool.

Intense methods, without compulsory method

Interval training has taken on an important role in discussions of endurance, particularly to get a high stimulus in a limited time. Research shows that intensity influences adaptations, but also that multiple formats can work. Health recommendations thus retain moderate and intense options: cardio is not reduced to the most spectacular method.
