Abstract: In the last seasons the junior baseball teams of Matanzas have shown poor effectiveness in the run of the bases, having speed a determining factor in the game and therefore essential to achieve success in a baseball game. The objective of this research is to design a combined plyometric-speed training to enhance the run to first base home in baseball junior category players. To do this, a training program is applied based on the combination of plyometric and speed exercises dosed in three stages: first, general strength and low intense plyometric exercises, then, the introduction of moderate intensity plyometrics, and finally, the combined work of plyometrics of moderate-high and high intensity with speed exercises. The sample studied was composed of ten junior players, who participated in the XLVI Cuban Baseball National Championship. Three measurements were taken: first, at the end of the anatomical adaptation phase, then at the end of the muscular hypertrophy phase and the beginning of the intramuscular coordination-maximal strength combined with explosive strength and finally in the special preparation stage. To analyze the effectiveness of the exercises proposed in the time of the first home base race and in the reaction time, analysis of variance is applied, with a level of significance equal to 0.05. It is shown that there are significant differences in the time taken in the test that included the home first base racing, between each of the moments of preparation that were made, with a decrease of 4.40%. Meanwhile, in the first base home test hitting the hand with which the player batted and the moments in which controls were made influenced in the home first base time, showing a decrease of 3.38% in the effectiveness of the first base home race between the controls and a 3, 31% in the left-handed players in relation to the right-handers. On the other hand, in the test with a medical ball of 3kg with rotational movement and home-first base race, a decrease in the time of effectiveness of 6.33% is reflected In the study, it is confirmed that there is a decrease in times with medical ball throwing (3kg) with rotational movement and home first base with a decrease in the effectiveness of 3.19% between the initial and final control.

Abstract: As the fastest racket sport in the world, playing badminton involves jumps, lunges, multidirectional movements with fast-spaced changes of direction, rapid postural changes, repetitive movements of upper limb and prolonged gripping of racket with high velocity movements. These high physical demands for badminton suggest that injuries related to badminton among players may have a frequent occurrence. Therefore, the epidemiology of badminton related injuries had been studied among competitive (elite and sub elite) players and recreational players of all ages in many countries. Therefore, the current review discusses the literature on epidemiology (incidence/prevalence, severity, location, type, competition/practice injuries) of badminton related injuries among competitive badminton players in diverse populations. The search strategy included PubMed, Science Direct and Google Scholar search from the year 1979. Fourteen (14) studies which have investigated epidemiology of badminton injuries were found. Injury incidence/prevalence was diverse in different populations. Majority of badminton related injuries are recoded as mild injuries. Lower limb was recorded as the most susceptible region for badminton related injuries. Overuse injuries have been recorded as the dominant type of injury. Dominance of competition/practice injuries was diverse in different populations. It is evident that the epidemiology of badminton related injuries shows a population difference. Investigating the epidemiology of injuries in a given population is required to understand the extent of injuries and identify the priority areas to implement specific injury prevention progammes.
