“…The overall injury incidence in the present study (IIR ME 35.88 (95% CI 30.70 to 41.68)) was lower than that reported by Pieter13 (IIR ME 138.46 (95% CI 113.58 to 167.17)) and Macan et al 14 (IIR ME 110.73 (95% CI 96.33 to 126.69)), but higher than that reported by Arriaza et al 15 (IIR ME 14.95 (95% CI 11.44 to 19.21)). The reason for these differences is unclear, but may be related to differences in study populations and/or methodology.…”

“…While the study populations in the present study (6–17-year-olds in Slovak national tournaments) and in the studies by Pieter13 (7–15-year-olds in one Dutch national tournament) and Macan et al 14 (12–17-year-olds in several Croatian national tournaments) are relatively similar, the study by Arriaza et al 15 featured 14–15-year-olds competing in three WKF World Karate Championships. In comparing their findings with those reported by Pieter,13 Arriaza et al 15 suggested that differences in competition rules may potentially explain the observed differences in injury rates. Another possible explanation is potential differences in operational injury definitions and injury recording procedures.…”

“…Similar findings were reported by Pieter and colleagues [32] in elite adult judo athletes. In taekwondo, female British competitors also exhibited similar characteristics [29], and the same pattern was observed in Dutch girl karatekas [28] and their Croatian counterparts [20]. It has been suggested that female athletes are more inclined to report an injury [4], although this has not been consistently confirmed via statistical analyses.…”

“…The injury rates of the younger judokas in the current study, however, were lower than those found in a more recent study [31] of Canadian boys (134.62/1,000 A-E, 95% CI: 64.10-205.14) and girls (333.33/1,000 A-E, 95% CI: 170.00-496.66) who practiced taekwondo. Dutch boy and girl karatekas also incurred more injuries (99.74/1,000 A-E (95% CI: 77.32-122.16) and 115.11/1,000 A-E (95% CI: 75.23-154.99), respectively [28]. Although the estimated percentages of injuries in the other studies were higher, the CIs generally overlap with the CIs of this study and do not clearly demonstrate significant differences, except between Filipino and Canadian girls.…”

SummaryStudy aim: The aim of this study was twofold: first, to compare the incidence of injuries between male and female athletes in the junior and youth divisions during competition, as well as to identify body parts commonly injured and the types of injury frequently incurred; second, to assess overall incidence of injuries in relation to the frequency and duration of training as well as supplemental training. Material and methods: Subjects were Filipino judokas (n = 192) competing in 4 major divisions at a national competition in Manila in 2009. Injury rates are expressed per 1,000 athlete-exposures, and the confidence intervals around the rates were computed.Results: There was no difference in injury rate between boys (84.03/1,000 athlete-exposures (A-E), 95% CI: 47.20-120.86) and girls (37.04/1,000 A-E, 95% CI: -14.29-88.37). Although the boys were at a higher risk than the girls, the difference was not significant (OR = 3.13, 95% CI: 0.62-15.76). The junior women were at a higher risk than the girls (OR = 6.30, 95% CI: 1.26-31.66). Neither training frequencies of ≤2, 3, and ≥4 sessions per week nor training durations of ≤2 and >2 hours were significant predictors of injury. Supplemental training was not found to be related to the occurrence of injuries. Conclusion: Judo is a relatively safe physical activity for young adults and children. Training variables, such as frequency and duration, and supplemental training do not influence the occurence of injury.

“…This, in turn, leads to a better performance, avoiding teaching and learning mistakes and preventing possible injuries that occur during practice or competition (Macan, Bundalo-Vrbanac & Romic, 2006;Pappas, 2007;Pieter, 2010;Zetaruk, Violan, Zurakowski & Micheli, 2005).…”

Presently, coaches and researchers need to have a better comprehension of the kinesiological parameters that should be an important tool to support teaching methodologies and to improve skills performance in sports. The aim of this study was to (i) identify the kinematic and neuromuscular control patterns of the front kick (maegeri) to a fixed target performed by 14 experienced karate practitioners, and (ii) compare it with the execution of 16 participants without any karate experience, allowing the use of those references in the analysis of the training and learning process. Results showed that the kinematic and neuromuscular activity during the kick performance occurs within 600 ms. Muscle activity and kinematic analysis demonstrated a sequence of activation bracing a proximal-to-distal direction, with the muscles presenting two distinct periods of activity (1, 2), where the karateka group has a greater intensity of activation -root mean square (RMS) and electromyography (EMG) peak -in the first period on Rectus Femoris (RF1) and Vastus Lateralis (VL1) and a lower duration of co-contraction in both periods on Rectus Femoris-Biceps Femoris and Vastus Lateralis-Biceps Femoris (RF-BF; VL-BF). In the skill performance, the hip flexion, the knee extension and the ankle plantar flexion movements were executed with smaller difference in the range of action (ROA) in the karateka group, reflecting different positions of the segments. In conclusion, it was observed a general kinesiological pattern, which was similar in karateka and non-karateka practitioners. However, in the karateka group, the training induces a specialization in the muscle activity reflected in EMG and kinematic data, which leads to a better ballistic performance in the execution of the maegeri kick, associated with a maximum speed of the distal segments, reached closer to the impact moment, possibly representing more power in the contact.Palabras clave: Kinesiology; electromyography; motor control; martial arts; combat sports.
