High-intensity intermittent test (HIT)

This is an intermittent test carried out on a treadmill, exercise bike or on the field, which allows us to assess the athlete’s physiological response to high-intensity intermittent exercise. At the end of the exercise protocol, droplets of blood are drawn from the earlobe and some parameters are measured, including pH, bicarbonate (the blood buffer system) and lactate concentration in the blood. This test is important for assessing changes in the athlete’s fitness, particularly in team sports that involve high-intensity intermittent activities.
