Fighting (F) and non-fighting (NF) relationship has been used to characterize the physical demands in taekwondo. The aim of this study was to analyze the time motion activity (F and NF) according to the weight category in taekwondo competitors. Time motion phases (F and NF) of 47 bouts of the first Cadet World Championship according to the weight category (fin, fly, bantam, feather, light, welter, light-middle, middle, light-heavy and heavy) were analyzed. Kruskall-Wallis followed by Mann Whitney U tests were used to analyzed differences between groups (p < 0.05). There are differences in F and NF according to the weight category. In NF phase, heavy athletes (welter, light-heavy and heavy) had longer NF periods than lighter athletes (fin, fly, light and light-middle). In F phase, fin, light-middle and light-heavy performed shorter F phases than fly, bantam, feather, light, welter, middle and heavy. It is concluded that trainings must be prepared to simulate competitive F and NF phases according to the weight category. Thus, coaches should propose to athletes F:NF ratios of activity similar to the real competition according to the weight category of each athlete.
