| description | Purpose: This study aimed to compare physiological responses and timemotion analysis between official and simulated karate combat. Methods: Ten high-level karatekas participated in this study, which included official and simulated karate combat. Results: Karatekas used more upper-limb attack techniques during official combat compared to simulated ones (6 [+ or -] 3 vs 3 [+ or -] 1; P=0.05, respectively). For official and simulated karate matches, the numbers of high-intensity actions (i.e. offensive and defensive fighting activity) were 14 [+ or -] 6 and 18 [+ or -] 5, respectively (P>0.05), lasting from |

Results: Karatekas used more upper-limb attack techniques during official combat compared to simulated ones (6 [+ or -] 3 vs 3 [+ or -] 1; P=0.05, respectively). For official and simulated karate matches, the numbers of high-intensity actions (i.e. offensive and defensive fighting activity) were 14 [+ or -] 6 and 18 [+ or -] 5, respectively (P>0.05), lasting from <1s to 5s each. Total fighting activity phase was lower during official compared to simulated matches (21.0 [+ or -] 8.2s vs 30.4 [+ or -] 9.9s, P<0.01, respectively). Effort (10.0 [+ or -] 2.8s) to rest (11.9 [+ or -] 2.7s) ratio (E:R) was 1:1 and high-intensity actions (1.6 [+ or -] 0.3s) to rest (11.9 [+ or -] 2.7s) ratio was higher than 1:7 during simulated combat. During official karate match, the activity and rest duration were 10.0 [+ or -] 3.4s and 16.2 [+ or -] 4.1s, respectively (E:R ratio 1:1.5), while high-intensity actions were 1.5 [+ or -] 0.3s, resulting in an E:R ratio of 1:11. Blood lactate concentration was higher during official (11.14 [+ or -] 1.82 mmol.[l.sup.-1]) compared to simulated karate combat (7.80 [+ or -] 2.66 mmol.[l.sup.-1]) (P<0.05). Subjective perceived exertion differed significantly between official and simulated combat (14 [+ or -] 2 vs. 12 [+ or -] 2; P<0.05, respectively). The majority of karatekas' perceived exertion was higher in the lower limb muscle groups irrespective of the karate combat condition. Conclusion: Official and simulated matches differ considerably, therefore coaches should create new strategies during training sessions to achieve the same effort and pause profile of competitive matches and/or that athletes should be submitted to frequent competitions to adapt themselves to the profile of this event.
