Taekwondo (TKD) is one of the martial arts and combat sports, which is gaining popularity
around the world. In order to prescribe a specific training program, which can elucidate the
metabolic demands during the competition, it is paramount to investigate the physiological
responses of different forms of competitions (i.e., poomsae and combat). Moreover, it is
important to know the physiological stresses associated with a variety of training forms to
better orient the training program for enhanced physical performance. Thus, the objective of
the present chapter is to present and explain the physiological responses of both specific forms
of training and competition, and then to recommend practical applications for the prescription
of TKD training programs.
