Judo training improves aerobic capacity, with VO₂max values similar to those of team sports athletes. It stimulates physiological hypertrophy of the left ventricle, improving cardiac function. Autonomic regulation shows a parasympathetic predominance, indicating better stress adaptation. Vascular adaptations include increased arterial elasticity and optimal blood pressure management, with judoka exhibiting lower blood pressure values than the general population.
