The Activity Profile of Elite Low-Kick Kickboxing Competition.
PURPOSE:
Determine the performance aspects (time-motion and technical-tactical analysis) of top-level low-kick kickboxers according to gender, weight-categories, combat rounds, and match outcome.
METHODS:
Seventy-two kickboxers (44-malesand 28-females) were studied. Thirty-six bouts (male=61, female=41 rounds) were analyzed using a time-motion system. Time structure was classified into three-phases: preparatory-activity time (PT), fighting-activity time (FT), and stoppage-activity time (ST).
RESULTS:
Referee's decisions caused an overall effort-pause ratio (E:P) of ~1:1.5, with a significant difference between weight categories (light and middleweights=1:1.5; and heavyweight=1:1). This ratio was ~1:6 when high-intensity actions-to-pause activities were considered. Significant differences were also observed between rounds (all, P<0.001), with1st, 2nd, and 3rdrounds E:P ratio of: 1:1, 1:1.5,and ~1:2, respectively. The relative times of FT and PT, total-attacking actions, upper-limb actions, number of technical actions performed on the head, and the number of high-intensity actions(HIA)were higher in males than females(all, P=0.05). Males performed higher number of jab-cross actions and fewer low-kick compared with females (P<0.001). Males used upper-limb (63.4%) more than lower-limb techniques (36.6%), targeting in the head (56.9%) more than the body/leg (43.1%) with no significant differences with females (P>0.05). E:P ratio was similar between winners and losers. However, the number of technical actions performed on the head, counter-attack actions, jab-cross technique and total punches were higher in winners than losers(all, P<0.05).
