Construction of a Sports Ludogram as a Form of Duel: Playing a sport is not anodine; it is the result of a symbolic representation of that sport. Studying the gestures of a player during a match, before or after winning a point, after an adversary's double faut or after a final winning point, can reveal that social symbolism by other than traditional methods. Sports reveal intense manifestations of emotions and how is one to account for the different modes of these emotional manifestations in relation to the stages of a match? Tennis, table tennis, field tennis, badminton and volleyball serve as our research terrain. We explain the development followed in constructing a methodological tool for data collection called the ludogram.
