Purpose: To assess the technical and tactical demands of elite karate athletes in relation to 3 match sequences (ie, advantage, disadvantage, and drawing) and match outcome (ie, win/defeat).Methods: One hundred twenty elite seniors’ (60 men and 60 women) World Karate Federation combats were analyzed during 2 World Championships (2012 and 2014). Specific karate attributes (strategy, technique, tactic, target, and effectiveness) were evaluated and classified into 3 sequences: advantage, disadvantage, and drawing. Results: Karatekas performed more combination techniques in disadvantage sequences than in drawing sequences (P = .011). A higher number of timed-attack actions were reported during advantage sequences than during drawing sequences (P = .048). Winners of the whole combat had higher lower-limb technique rate (1.0 [0.9] vs 0.1 [0.3]; P = .044) and less rate of timed attack (0.3 [0.5] vs 0.6 [1.0]; P = .030) than defeated karatekas during advantage and drawing sequences, respectively. Conclusions: Winners used higher lower-limb technique and less timed-attack rates than defeated karatekas in advantage and drawing sequences, respectively. Indeed, using lower-limb technique during advantageous situations could be a powerful strategy to increase the lead. Therefore, it seems fundamental for coaches of top elite karatekas to put their athletes in simulated situations and push them to increase their use of lower-limb techniques.

Purpose: To evaluate the concept of decisive moment (DM) as a novel analysis approach providing insights into factors leading to successful high-performance k umite karate outcomes using time–motion variables. DM represents the moment from which 1 of the 2 opponents uninterruptedly dominates the other until the end of the fight. Methods: A total of 120 elite seniors (60 men and 60 women) World Karate Federation combats were analyzed during 2 World Championships (2012 and 2014). Specific characteristics of karate combat (strategy, technique, tactic, target, and effectiveness) were evaluated and classified in 3 sections: at, before, and after DM. Results: DM occurred at about 49% (32.8%) of bout duration. Up to DM no clearly identifiable differences in performance characteristics were found between winners and losers. At and after DM, an offensive strategy with focus on upper-limb techniques, attack and counterattack, targeting the head showed highest potential to achieve and maintain dominance and to win. After DM, losers showed increasingly reactive techniques, mainly timed attacks and combinatory techniques. Conclusion: The DM concept presents a novel approach to time–motion analysis, which for the first time allowed identification of clear discriminating factors of success and defeat in kumite karate at the highest performance level.

Many forms of mainstream coach education continue to sparingly address content specifically related to positive youth development and/or life skills, instead maintaining a focus on the technical and tactical aspects of sport. The purpose of the paper is to present the evaluation findings of the pilot implementation of the Coaching for Life Skills program, designed to serve coaches operating in the context of high school sport. The study qualitatively explored what participants believed they experienced during their participation in the Coaching for Life Skills program, which was delivered to 68 Canadian high school coaches. Participants took part in one of six three-hour workshop (i.e., three workshops in English, three workshops in French). Of these 68 coaches, 10 voluntarily agreed to take part in individual semi-structured interviews. Findings demonstrated how the participants believed they learned important elements related to the coaching of life skills, particularly in terms of increasing their awareness of life skills, improving coach-athlete relationships, and employing coaching strategies that deliberately target life skills development and transfer.

Despite this, real climbing performance requires coordinative action of whole body musculature, where mental, technical, and tactical aspects are involved. The increase in climbing performance after

Psychosocial development reflected player perceptions regarding psychological aspects of learning experience and the opportunity to feel leadership and mentoring. The overall experience
