Stress test for sportsmen and women

"The sports checkup allows to rule out possible pathologies that contraindicate the sports practice, and in this way to carry it out without risks and to avoid injuries that are derived from an inadequate practice".


The Clinica Universidad de Navarra offers effort tests especially directed at sportsmen and women or people who wish to start in sports.

Conducted by medical specialists in the area of Sports Medicine, the objective of the stress tests is to evaluate the response of the organism during physical effort.

In this way, the anaerobic threshold of each individual is determined, at which point the sportsperson's muscles are no longer capable of consuming glucose and begin to synthesize lactic acid. These thresholds are a fundamental part when designing a training plan and knowing the ideal intensity when training.

In the Clinic, the test of effort is integrated in the Sport Valuation, examination that looks for to offer to the sportsman a deeper study than the one that could offer a test of independent effort, including in addition to this one, a series of tests, controls and additional recommendations to manage to improve the sport performance and a free activity of risks.

When is the stress test for sportspeople indicated?

The stress test determines the anaerobic threshold, which occurs at a certain heart rate (beats per minute). Once this threshold is exceeded, the body begins to produce lactic acid and sports performance begins to decline.

Knowing this level, an appropriate training plan can be defined in order to raise the threshold and improve sports performance.

Thus, the stress test serves to determine the appropriate level of physical effort for each individual so that training is more productive and progress is made more quickly and effectively.

In addition, it allows the detection of some arrhythmias, myocardiopathies and congenital or rheumatic cardiopathies, or the prognosis of some heart diseases, avoiding risks in the sport activity.

How is the stress test for athletes carried out?

In all effort tests, the aim is to bring the athlete in a controlled way to the point of exhaustion in order to assess the body's response. This can be achieved on a treadmill, where the patient runs, or on a cycloergometer, if the athlete is a cyclist and prefers this option.

The stress test can be performed with greater or lesser complexity. The most complete version is the one that includes the measurement of the body's gas consumption and an electrocardiogram to evaluate the heart's response, for whose interpretation a specialized physician is indispensable.

Stress tests are generally safe. Some patients may have chest pain or may faint or fade. A heart attack or dangerous irregular heart rhythm rarely occurs.

Usually, people who are likely to have such complications are known in advance to have weak hearts, and are not usually tested.

After the test you can resume your normal activities.

During the subsequent sports practices, you should take into account the recommendations based on your aerobic and anaerobic thresholds to achieve greater sports performance.
