“…In addition to that, it is possible to affirm that karate is characterized as an intermittent modality of moderate to high intensity, according to the illustration in figure 3 (A and B), corroborating previous studies 3,4 and other modalities of martial arts [23][24][25] . Training stimuli from modalities with intermittent characteristics are efficient in promoting the significant increase in O 2max o pre-puberty children 26 , young adults, middle-aged 27 and elderly subjects 28 , of both sexes 27 , regardless of the training level, since the responses in the cardiorespiratory indices include from sedentary subjects to athletes 27,29 .…”

Karate practice can promote beneficial adaptations on the health-related components of physical fitness. Among the components, the maximum oxygen uptake ( O 2max ) is an important indicator of cardiorespiratory fitness, as it is also a strong and independent predictor of the risk of death from cardiovascular disease and all other causes. Previous studies have evaluated the heart rate (HR) responses in the karate modality during protocols elaborated by researchers who simulated training. However, the results should be carefully interpreted, since elaborated protocols can compromise the ecological validity of the HR behavior. Thus, the aim of the study was to monitor the HR to investigate the distribution of intensity during a karate training session (TS) with ecological validity preserved. Nine athletes (M (SD) = 22 (5.2) years; 60.3 (12.9) weight; 170.0 (0.10) height; 170.0 (0.10) cm; 11.6 (5.7) % fat) performed a maximal incremental test (IT) and one TS with continuous HR monitoring, subsequently distributed by Edward´s method. The mean TS duration was 91.3 (11.9) min (IC95% = 82.0 -100.5). The values of average and maximum HR of the TS were equivalent to 72 % (IC95% = 66 -78 %) and 94 % (IC95% = 89 -99 %) respectively, of maximum HR reached in the incremental test (HRmax). During 79.9 % (IC95% = 65.7 -94.1 %) of the total time of TS the athletes remained at intensity above 60% of HRmax. Thus, it was concluded that the TS lies within the ACSM recommendations concerning intensity, duration and weekly frequency, presenting itself as an interesting alternative of exercise to promote cardiorespiratory fitness.

“…Sometimes cardiovascular demands remained stable through the matches. This result is similar to that reported by another research who observed a small variation in HR in two karate combat simulations, one of 2 min and another of 3 min duration (Bouhlel et al 2006;Lide et al 2008). …”

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. While post-match BLs of athletes increase by 4.02 times compared to pre-match regardless of the gender, this increase was determined as 4.20 for male athletes and 3.82 for female athletes.Kickboxing is a combat sport which has high intensity of anaerobic physical fitness. Matches and rounds for HR and BL concentrations show the importance of the aerobic metabolism in kickboxing. However, the significant rise of HR and BL during simulated match indicates that the anaerobic metabolism is also important in kickboxing.

“…Kata represents a pre-arranged form of karate techniques in an exhibitive manner. Kumite means karate sparring, which involves the execution of offensive, defensive and counter-attack techniques against a rival [22,23]. Based on the World Karate Federation rules, an official kumite competition lasts 3 minutes for senior males and 2 minutes for senior females in elementary stages, and then lasts 1 more minute for each of them in the final stages and fight for medals [11].…”

SummaryStudy aim: The purpose of the present research was to determine the physical and physiological features of international level karate athletes. Material and methods: Eleven male karate athletes who were ranked at the top of their weight categories participated in this study. All of them were evaluated for anthropometric, body composition, somatotype and bio-motor characteristics in detail. Results:The main results (mean ± SD) were height: 181.54 ± 4.71 cm; sitting height: 97.27 ± 3.03 cm; arm span: 185.72 ± 7.28 cm; BMI: 25.02 ± 3.32 kg • m -2 ; Rohrer's index: 137.68 ± 16.72; skelic index: 53.58 ± 1.29; arm span (ape) index: 1.02 ± 0.02; fat mass: 7.51 ± 4.56 kg; fat-free mass: 75.26 ± 10.04 kg; body fat: 8.66 ± 3.65; endomorphy: 2.4 ± 0.85; mesomorphy: 5.2 ± 1.13; ectomorphy: 2.11 ± 0.99; VO 2max : 51.58 ± 3.39 ml • kg -1 • min -1 ; anaerobic power: 45.45 ± 4.39 W • kg -1 ; long jump: 249.7 ± 16.81 cm; upper-body strength: 100.27 ± 15.61 kg (1.21 ± 0.07 kg • kg -1 ); lower-body strength: 155.94 ± 19.49 kg (1.89 ± 0.14 kg • kg -1 ); whole-body strength: 156.97 ± 21.38 kg (1.9 ± 0.13 kg • kg -1 ) and flexibility: 37.63 ± 10.73 cm. Conclusions: A tall stature and long arm span, low body fat, markedly high mesomorphic build, moderately high aerobic power, outstanding anaerobic power, excellent lower-body explosive power, great muscular strength and high flexibility seem to be advantageous features for karate contestants.
