How does the body lose physical strength?

Regular exercise increases both strength and endurance. Therefore, if you take a long break from exercising, both of these factors decrease. Many studies have made interesting findings about this decline, according to the health information website Everyday Health (USA).

Taking a break from training for two consecutive weeks can cause endurance to start to decline.

In terms of endurance, we can improve it with cardio exercises such as running. Activities like cycling, swimming, or dancing can increase endurance. The body's stamina improves with sustained physical activity over extended periods. The heart and lungs adapt to this intensity and become increasingly resilient.

Endurance won't be affected by a few days off from training, but it will gradually decrease over time. Generally, endurance will show a noticeable decline after two weeks of inactivity. A study in the journal Frontiers in Physiology found that the endurance of cardio enthusiasts began to decline after an average of 12 days without training.

There isn't much scientific evidence to indicate exactly how long it takes for endurance to completely decline after a period of inactivity. However, experts say this period can be several months, depending on the individual.

Another factor that declines when you stop exercising is strength. To improve strength and increase muscle mass, exercisers regularly perform exercises such as weightlifting, squats, push-ups, or pull-ups. Experts say that strength and muscle mass will not be significantly affected after 2-3 weeks of stopping exercise. Furthermore, this decline also depends on many factors such as age, gender, diet, hygiene, sleep, and physical condition before stopping exercise.

A study published in the International Journal of Exercise Science found that even after three weeks without exercise, the volunteers' muscle mass, strength, and athletic performance were unaffected.

Experts say that taking a few days off from training, or even a week or two, occasionally can be beneficial for the body. This break isn't long enough to significantly impact strength or endurance. Instead, it allows the body to rest and recover better, preparing it for a new training routine, according to Everyday Health.
