Abstract

Purpose:

This study aimed to compare physiological responses and time-motion 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 (63 vs 31; P=0.05, respectively). For official and simulated karate matches, the numbers of high-intensity actions (i.e. offensive and defensive fighting activity) were 146 and 185, respectively (P>0.05), lasting from <1s to 5s each. Total fighting activity phase was lower during official compared to simulated matches (21.08.2s vs 30.49.9s, P<0.01, respectively). Effort (10.02.8s) to rest (11.92.7s) ratio (E:R) was 1:1 and high-intensity actions (1.60.3s) to rest (11.92.7s) ratio was higher than 1:7 during simulated combat. During official karate match, the activity and rest duration were 10.03.4s and 16.24.1s, respectively (E:R ratio 1:1.5), while high-intensity actions were 1.50.3s, resulting in an E:R ratio of 1:11. Blood lactate concentration was higher during official (11.141.82 mmol.l-1) compared to simulated karate combat (7.802.66 mmol.l-1) (P<0.05). Subjective perceived exertion differed significantly between official and simulated combat (142 vs. 122; 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.
