In karate, precision, high speed, and tech- nique are the hallmarks of attack, counterattack, and defence. The aim of this study was the phase relation- ship between the proximal and distal joints during the execution of two technique of stroke karate: the punch gyaku tsuki and the kick mae geri. Material and Methods: The study included 14 male athletes, equally divided into 2 subgroups according to their current competi- tive level: sub-elite (SEG) and elite (EG). The karate stroke performance measure used was the linear veloci- ty peak of the wrist and foot. In order to analyze the intra-segment coordination, it was applied the nonlinear dynamics approach named continuous relative phase (CRP). From the CRP curve it was obtained the peak as well as the time to reach the CRP peak. It was also compared the index of the coordinative patterns’ variabil- ity, which was obtained by calculating the average of the CRP values and standard deviation. Results: The EG group showed significantly higher values in the linear velocity peak of the wrist and foot when com- pared to the SEG. With respect to the CRP curve peak and the coordinative patterns variability, the SEG group presented significantly higher values, showing no differences in the time to reach the CRP peak. Conclusions: The EG group presented a better intra-segment coordinative capacity during the execution of strikes. The sta- bility of coordinative patterns seems to have an intimate relationship with the technical refinement. Thus, this variable can be configured also as a predictor of performance.

Helmi Chaabène, Emerson Franchini, Bianca Miarka, Mohamed Amin Selmi, Bessem Mkaouer, and Karim Chamari Purpose: The aim of this study was to measure and compare physiological and time–motion variables during karate fighting and to assess eventual differences between winners and defeated elite karatekas in an ecologi- cally valid environment. Methods: Fourteen elite male karatekas who regularly participated in national and international events took part in a national-level competition. Results: There were no significant differences between winners and defeated karatekas regarding all the studied variables. Karatekas used more upper-limb (76.19%) than lower-limb techniques (23.80%). The kisami-zuki represented the most frequent technique, with 29.1% of all used techniques. The duration of each fighting activity ranged from <1 s to 5 s, with 83.8% ± 12.0% of the actions lasting less than 2 s. Karatekas executed 17 ± 7 high-intensity actions per fight, which corresponded to ~6 high-intensity actions per min. Action-to-rest ratio was about 1:1.5, and high-intensity- action-to-rest ratio was ~1:10. The mean blood lactate response at 3 min postcombat (Lapost) elicited during karate fighting was 11.18 ± 2.21 mmol/L (difference between Lapre and Lapost = 10.01 ± 1.81 mmol/L). Mean heart rate (HR) was 177 ± 14 beats/min (91% ± 5% of HRpeak).

För att underlätta uttalet anger jag lång vokal med ett streck ovanför, vilket framgår av ovanstående rubrik. Jag skriver japanska ord och uttryck med kursiv, med undantag för sådana ord som är helt ac- cepterade i svenska språket, t.ex. karate och budo.

  • Compare the Values of Blood Lactate and Heart Rate of Kickboxers During Kickboxing Matches
    Journal of Education and Training Studies Vol. 5, No. 7; July 2017 ISSN 2324-805X E-ISSN 2324-8068 Published by Redfame Publishing URL: http://jets.redfame.com Compare the Values of Blood Lactate and Heart Rate of Kickboxers during Kickboxing Matches Mustafa Karadağ Correspondence: Mustafa Karadağ, Firat University, Faculty of Sports Science, 23119, Elazig, Turkey. Received: April 4, 2017 Accepted: May 25, 2017 Online Published: June 1, 2017 doi:10.11114/jets.v5i7.2317 URL: https://doi.org/10.11114/jets.v5i7.2317 Abstract The aim of this study was to compare the values of heart rate (HR) and blood lactate (BL) of kickboxers during kickboxing match. This study was conducted with the participation of 18 male and 16 female sportsman in Turkish Kickboxing championship, an organization of Turkish Kickboxing Federation. After the participant athletes read and signed informed voluntary consent form (BGOF) prepared for them, the measurements were collected. While no significant difference was found between ages, pre-match HR, post-match HR, pre and post-match BL of male and female Kickboxers, a significant difference was statistically found between the height (P˂0.05) and body weights (P˂0.01) of athletes. Age distribution of athletes was determined as 14-23 and mean age distribution was determined as 17.03±2.41. HR pressures of athletes differs according to pre-match and post-match periods (P˂0.001). As HR frequencies increase by 29.4% according to pre-match HR regardless of the gender, this increase was determined as 31.4% for male athletes and 27.2% for female athletes.

Department of Physical and Sport Education, Faculty of Physical and Sport Sciences, University of León, Vegazana Campus, 24071–León, Spain Abstract: Aging leads to a general decline in body functions that affects quality of life. Sports practice is recommended as a means to attenuate the impact of the aging process. The aim of this study was to identify and analyze the neuromuscular activity and its patterns on active karate practitioners and assess the effects of the aging process. Two groups of black belt male karate practitioners, one with nine practitioners over 50 years old and the other with 21 practitioners aged between 20-30 years old performed the frontal kick mae-geri. Kinematic and electromyographic data of five muscles were collected from the right leg. Results showed two distinct periods of muscular activation in the mae-geri performance, with similar muscles activity patterns between groups. Nevertheless, some differences were found in the muscles’ activity onset and offset, in root mean square and in inter-muscle delay and co-contraction periods.

A system of 25 variables in total – 12 morphological, 12 basic motor (the system of predictor variables) and 1 variable of situational moving structure (criterion variable), i.e. the karate punch with the lead arm (oi-tsuki) – was applied on a sample of 82 karate trainees aged between 10 and 14.
