How does the body lose physical strength?

When you exercise regularly, your body will increase both strength and endurance. Therefore, if you stop exercising for a long time, both of these factors will decrease. Many studies have made interesting findings about this decline, according to the health information site Everyday Health (USA).

Taking two weeks off from training straight can cause your endurance to start to decline.

With endurance, we can increase it with cardio exercises like jogging. , cycling, swimming or dancing. Endurance is increased when the body moves continuously for a long time. The heart and lungs adapt to this intensity of exercise and become more durable.

Endurance isn’t affected by a few days off, but it does decrease over time. In general, endurance starts to decline significantly after two weeks of not exercising. A study in the journal Frontiers in Physiology found that the endurance of people who do cardio starts to decline after an average of 12 days without exercise.

There is little scientific evidence to suggest how long it takes for endurance to completely decline after not exercising, but experts say it can take several months, depending on the individual.

Another factor that is reduced when stopping training is strength. To improve strength and increase muscle mass, people will regularly perform exercises such as weight lifting, squats, push-ups or pull-ups. Experts say that strength and muscle mass will not be affected much after 2-3 weeks of stopping training. In addition, this reduction also depends on many factors such as age, gender, diet, hygiene, sleep and physical condition before stopping training.

A study published in the International Journal of Exercise Science found that despite three weeks of no exercise, volunteers' muscle mass, strength and performance were not affected.

Experts say that occasionally taking a few days off from training, even 1-2 weeks, can be beneficial for the body. This break is not long enough to affect strength and endurance. But in return, the body will rest and recover better to return to a new training routine, according to Everyday Health.
