Efecto agudo de los entrenamientos de fuerza, velocidad, pliometría y velocidad contra resistencia en la carrera de velocidad

Speed plays a main role in sport performance in both collective and individual sports. The aims of this study are: a) to determinate the acute effect of speed, strength, resisted speed and plyometric training on speed performance and speed phases, and b) to analyze the performance data with individual and group analysis. Eleven sprinters (mean age of 21.8 ± 3.04, height of 1.764m ± 0.062 and weight of 69.645kg ± 4.946), with experience as sprinters in 100, 200 or 400m events participated in 5 training sessions assigned in a random order. Each condition was performance on different days, separated by at least 48 hours, and a 100-meter test was applied before and after each condition. Time recording was performance every 20 meters in the 100m test. Two way and three-way variance analysis (ANOVA) of repeated measurements were performance with the aim of studied the effect of the types of training on the speed race and on their distance intervals. Statistical descriptive and graphics were used for the individual analysis. For the group analysis, no significant interaction was found between measurements and types of trainings (F = 1.733 p = 0.162), and between measurements, distance intervals and types of trainings (F = 0.569 p = 0.903). However, in the individual analysis it is noted the differences between athletes on the response to each training type, being the speed training the one in which more subjects enhanced.
