“…A number of key technical points have been identified based on kinematic analysis of elite and subelite military personnel (21) and combat athletes (7,13). The initial phase should be in a stance with the body mass centered on the back lower limb; however, this might vary due to the tactical approach or an unexpected situation.…”

“…Several studies have shown that the dominant muscles during kicking are the hip and knee flexors and extensors, hip rotators, tensor fascia lata, and ankle flexors (2,19,21,23,26). Hip muscle moment is most pronounced about 100 ms before impact (19), and shin velocity is generated primarily by the rectus femoris and vastus lateralis.…”

“…The dynamic outcome of the kick is also dependent on the product of mass, linear velocity (6), and the angular velocities of the kicker's body segments and joints (4). Thus, the coordination of the kinematic chain is critical in ensuring the effectiveness of the kick technique (2,21). For example, there is a relationship between the velocity of the knee and foot and the values of F max (27).…”

“…Although the front push kick is a relatively easy movement pattern to execute, specific technique training and conditioning is irreplaceable for its performance development. This is especially true if the push kick is performed under different loading and fatigue conditions in military close combat (21).…”

Kicking is an essential skill for combat athletes and military personnel. Therefore, the aim of this article is to present evidence-based training principles to achieve beneficial changes in technique and performance through functional training. The profile of subelite and elite kickers is presented and is used as a foundation for exercise prescription in both populations. The article emphasizes the importance of combining both functional training with a core emphasis and traditional general strength preparation to improve all aspects of front push kick performance. Example training programs for both subelite and elite kickers are presented that are based on a block periodization approach.

Background: The need for a strong grip in ‘ground’ martial arts is undisputed, but it is not obvious in karate. It may be expected that in the case of advanced karate fighters where dynamic combat movements dominate, the level of speed skills will be high. However, does the karate style affect the Ditrich rod dexterity and the strength of the players’ handshake? Methods: 39 participants were analyzed, all of whom were elite karate fighters—21 in the Kyokushin style (age: 31.4 ± 6.3; body weight: 77.2 ± 18.2 kg) and 18 in the Shotokan style (age: 23.3 ± 11.8 years; body weight: 70.9) ± 14.2 kg). They performed the following: a test of reaction speed and dexterity with a Ditrich rod, and a hand grip strength test with a dynamometer. Results: The data shows that there is no difference in the Ditrich rod test for both the left and right hand among the analyzed Kyokushin and Shotokan fighters. Significant differences were recorded in the grip strength of both hands (p < 0.05). There is a positive correlation between the strength of the grip on both hands (r = 0.593; p < 0.05). Discussion: Kyokushin-style karate players have a higher grip strength than those trained in the Shotokan style. Perhaps this is due to differences in the preparation for fights. The analysis showed no statistical significance in the Ditrich rod test. It is probable that the level of dexterity in karate is independent of the training canon.

Principal Component Analysis can Be Used to Discriminate Between Elite and Sub-Elite Kicking Performance

Contemporary descriptions of motor control suggest that variability in movement can be indicative of skilled or unskilled performance. Here we used principal component analysis to study the kicking performance of elite and sub-elite soldiers who were highly familiar with the skill in order to compare the variability in the first and second principal components. The subjects kicked a force plate under a range of loaded conditions, and their movement was recorded using optical motion capture. The first principal component explained >92% of the variability across all kinematic variables when analyzed separately for each condition, and both groups and explained more of the variation in the movement of the elite group. There was more variation in the loading coefficient of the first principal component for the sub-elite group. In contrast, for the second principal component, there was more variation in the loading coefficient for the elite group, and the relative magnitude of the variation was greater than for the first principal component for both groups. These results suggest that the first principal component represented the most fundamental movement pattern, and there was less variation in this mode for the elite group. In addition, more of the variability was explained by the hip than the knee angle entered when both variables were entered into the same PCA, which suggests that the movement is driven by the hip.
