Benefits of measuring cardiac vagal tone in athletes

• It provides an accurate measure of the degree of the brain's restraint of the heart, which can be used to indicate the strength and efficiency of the heart.



• The linear unit in which cardiac vagal tone is measured allows serialisation of the responses of the heart to physical training, or to particular regimes of exercise. A training curve can be established for the athlete.



• It helps the training instructor to design exercise that is most appropriate for improving cardiovascular performance of the athlete.



• It provides individual athletes with their own numerical upper limits of cardiovascular performances or responses to exercise and prevents the over-training that can cause irregular heart beats and unfitness.



• It indicates deterioration of cardiovascular performance due to inappropriate or   lack of exercises.



• Athletes can use it for numerical ranking of their cardiovascular fitness. There is no such facility at present in the world.



• It measures cardiac reserve by assessing cardiac vagal tone (the higher the cardiac reserve, the   fitter the person)
