T-pattern detection in combat sports

Abstract

By identifying and analysing temporal patterns (T-patterns) in behaviour, this study aims to detect technical errors and behavioural sequences in the kosoto gari judo throw, and, based on this, to propose changes to the way in which judo is taught. The participants (n = 50: 38 men and 12 women; Mage = 19.23 years, SD = 1.12) were students studying for a physical education and sports science degree with no previous experience of judo. This was a systematic observational study in which the students were filmed performing the kosoto gari technique. The results, derived from descriptive statistics and a sequential analysis of T-patterns conducted by means of Theme 5, revealed that the students committed a series of typical errors when learning to perform the throw. Furthermore, these errors often appeared in sequence, mainly involving a lack of balance, the position of the feet and hips/trunk, an incorrect reap and the final arm movement. The results can be used to propose movement sequences that would ensure that the throw is learnt correctly, and also to enable recommendations to be made regarding the use of feedback.
