ANALYZING HITTING, KICKING, AND THROWING SPEED JOSE PALAO, PHD, CSCS, AND DAVID VALADES, PHD I n sports, the higher the level of competition, the higher speed of execution and subsequently, the less time there is for the players to execute. In sports where athletes have to hit, kick, or throw a ball, one of the keys for success involves the players’ ability to accelerate the game and reduce the opponent’s response time (e.g., kicking toward the goal, pitching, etc.). Improving the hitting, kicking, and throwing ability usually involves an increase in the athlete’s strength and/or an improvement in the movement mechanics (3). To monitor the ball speed in practice and in competition, it is possible to use radar (immediate feedback) or video analysis (indirect feedback). This monitoring can be done in isolated situations or in integrated situations. The use of these instruments allows coaches and strength and conditioning professionals to assess how the athletes are executing their movements objectively. Specific literature about strength training indicates that a speed reduction of more than 10% means that practice is not adequate for training the strength application (1). The measurement protocol must be established and followed for all the measurements in order to monitor the speed execution reliably (2). The goals for monitoring, level of the athletes, the instruments, and resources available must be considered in order to establish this protocol and the conditions of the measurement (generic or specific situation). Ideally, the monitoring should be done in real and simplified situations. The number of measurements per session, per week, etc. will vary in relation to the number of athletes to be evaluated, resources that are 42 available, time spent per athlete to perform the measurement, and level of integration with the practice. Once the data are obtained, they should be analyzed at least three ways. First, there should be an analysis of the data from each measurement; the data should be analyzed each time. This gives information about how the athlete is executing and his/her shape in this specific moment of the season. Secondly, the data accumulated throughout the season gives information about the evolution of the athlete and the effect of the training. Third, which is more general, involves comparing the values with reference values of the population and/or team. This allows for the needs and goals to be established for the athlete in the short-term as well as the long-term. 1. First level of analysis: qualitative analysis of the practice/ execution. During the season, the data are accumulated and a mean and/or speed peak can be established. From this reference value, the execution of the athlete must not descend more than 10% of the peak speed (1). This calculation can be done easily with a spreadsheet. Executions done in training under this value do not necessarily ensure that the training is valuable. If the data are obtained with radar, the data will allow for immediate feedback to the athlete; which, in turn, allows strength and conditioning professionals and coaches to monitor the quality of the practice in order to help keep athletes involved in practices.
