Relying on modern means, the objectivization of the essential characteristics of strikes in relation to fighter's stances can provide elements able to lead, on the one hand, to their efficiency in the improvement process and, on the other hand, to the establishment of some basic technical elements incorporated into the learning algorithm. Hypothesis: Plantar pressure determines the strike efficiency. Objectives: To determine the relation among the fighting stances, strikes, plantar pressure and the execution speed within a checking experiment using one single group of subjects. Subjects: The research included 10 performance athletes (males) aged 21 to 24 years old. Initially, they were part of a sample made up of 35 subjects. Among the selection criteria (others than age), we mention the following: performance level, weight class and urban/rural provenance. Methods: The characteristics of our research required us to use the basic methods: observation method, questionnaire-based inquiry method, conversation method, test method, computerized method, statistical-mathematical method, but also the Pedar-X plantar pressure measurement system. Among the measures valorizing the plantar pressure, we mention: maximum pressures, mean pressures, aria. Results: The device software can emphasize, at the display level, the following elements: plantar print, pressure distribution on each of the insole sensors, 3-D pressure distribution, 2-D pressure distribution, gate analysis etc. Conclusions: The device used in our research (Pedar-X) allowed us to emphasize technical aspects extremely important to the field of motor activities, which can be implemented both in the learning initial stage and in the performance stage (by correcting the technical elements). An appropriate stance determines an appropriate plantar pressure, respectively an increased speed potential concretized in an increased efficiency. Plantar pressure becomes thus a technical landmark which determines the possibility to perform at an increased speed potential. The obtained results validate our research hypothesis and reject the statistical (null) hypothesis, a fact that compels us to extend to other technical aspects some studies which can prefigure new perspectives in the performance athletes' training. |
