“…Performance in TKD is related to technical and select physical fitness components [4,5]. Among the physical fitness components -anthropometry, aerobic fitness sand neuromuscular function have been identified as important determinants of performance [6,7]and are evaluated routinely in athletes [8]. Relative to anthropometric characteristics, body height, body mass, body mass index (BMI), and body fat percentage (BF) have been shown to be critical [9,10].…”

Herbal products and supplements use by athletes has increased over the past decade. One such item being polyphenols. These are reported to reduce weight and modify body composition, which could aid athletes in many sports. Therefore, the purpose of the study was to determine the effect of 6 weeks supplementation with carob, a naturally occurring polyphenol, on body composition and aerobic capacity in youth taekwondo athletes. Twenty-three taekwondo athletes (21.9±1.2 years; 1.64±0.03m; 67.4±17.3kg;BMI: 22.8±5.5 kg/m 2) participated in a short-term (6-week) double-blind randomized design parallel fully controlled training study (pre-to-post measurements): Supplemented group (SG), n=11;placebo group (PG), n=12. Body composition, aerobic capacity, heart rate and RPE were analyzed before and after 6weeks of carob rich polyphenol ingestion. Significantly greater decreases in weight were observed for SG and PG (-2.82% and-0.51%respectively) with differences between groups (p<0.001). No significant differences were reported in percentage body fat and muscular volume between groups. Our results revealed an improvement of aerobic performance score and RPE with differences between groups. A cute polyphenol supplementation seemed to be effective in reducing body weight and improving aerobic performance in athletes.

“…Research in other combat sports, such as taekwondo (5) and kickboxing (6), examined the responses of HGS, CMJ and heart rate (HR) to official or simulated combats. In kickboxing, HGS decreased after an official combat and the magnitude of decrease was larger in winners than in losers (6).…”

“…In kickboxing, HGS decreased after an official combat and the magnitude of decrease was larger in winners than in losers (6). In taekwondo, CMJ increased and HGS likely decreased after a simulated combat (5). In addition to the acute physiological responses to boxing, a lack of information has also been shown with regards to the impact of different recovery strategies during breaks on these responses.…”

Previous research has well described the acute responses of the human body to boxing; nevertheless, less data exist about the effect of recovery modes differing for body position during breaks on these responses. Therefore, the aim of the present study was to examine the impact of two modes of break (sitting versus standing) on heart rate (HR), rate of perceived exertion (RPE), countermovement jump (CMJ) and handgrip muscle strength (HGS) in a simulated boxing combat of three 3-min rounds with 1-min breaks. Participants were male boxers (n = 15) with age, body mass, body height, body mass index and training experience of 21.4 (6.3) yrs, 67.7 (10.0) kg, 172 (6) cm, 22.9 (4.2) kg.m -2 and 2.9 (1.9) yrs, respectively. Mean HR was recorded through all rounds and breaks. Immediately after each round, participants were questioned for RPE (6 -20 Borg scale). CMJ and HGS were measured before and after combat. A mixed analysis of variance found no time × body position interaction on variables (P > 0.05). However, the p value almost reached statistical significance (P = 0.062, η 2 = 0.426) in the case of RPE, that was, compared to the sitting position, a trend of increased RPE for the standing position across time was observed. A main effect of time on HR, RPE and CMJ was shown (P < 0.05), in which (a) HR was higher in the third round than the second and the first one (187, 184 and177 bpm, respectively, P < 0.001, η 2 = 0.609), (b) RPE was higher in the third round than in the first one (14.7 vs. 12.6, respectively, P = 0.047, η 2 = 0.457) and (c) CMJ after combat was higher than before (34.1 vs. 32.1 cm, respectively, P = 0.007, η 2 = 0.443). Even though this study did not provide evidence for different physiological impacts of body position during break in simulated boxing combat, it was indicated that manipulating the body position might affect the perception of effort.

Anthropometry and neuromuscular fitness have been shown to relate with taekwondo (TKD) performance; however, little information is available on the variation of these fitness components by sex and age in athletes practicing this sport. The aim of the present study was to examine the anthropometry and neuromuscular fitness of TKD athletes by sex and age. A total of 393 athletes (7–48 years old), separated into six age groups (7–9, 10–11, 12–13, 14–17, 18–32, and 33+), were examined for anthropometry and performed a series of neuromuscular fitness tests (flexibility, agility, muscle power, and isometric strength). An age × sex interaction on body mass, body height, and body fat percentage (BF, p≤0.003, η2≥0.045), but not on body mass index (p=0.172, η2=0.020), was shown, where a larger increase in body mass and body height from 12–13 to 14–17 groups was observed in males than in females, and the sex difference in BF increased from 12–13 to 14–17 age group. An age × sex interaction on sit-and-reach (SAR) test, mean power output in the Bosco test, and Abalakov jump (p≤0.038, η2≥0.031) was observed with larger differences between 12–13 and 18–32 groups in males than in females. In SAR, it was remarkable that the male athletes achieved similar scores as female athletes in the 18–32 group. An age × sex group interaction on measures of isometric muscle strength (right and left handgrip, trunk, and legs) was also shown (p≤0.002, η2≥0.068), where larger differences in male than female athletes were observed between the 12–13 and 14–17 groups. From a practical perspective, coaches can use these findings as reference for the evaluation of their athletes. Because the anthropometric characteristics and neuromuscular fitness varied by sex (i.e., highest scores in males, except flexibility) and age (i.e., highest scores in the 18–32 age group) with unique sport-specific patterns in TKD athletes, these findings would be important for the development of specific training programs.
