Effects of Individualized Strength-Speed Training on the Power of Two Young Soccer Players

A Case Study

Abstract

Both strength and speed are physical abilities that have been partially analyzed by working them separately, however, Power reflects the relationship between Force and Speed ​​(P = F x V) which recognizes the amount of force generated in an activity where there is a speed. The relationship of Force-speed (F-V) and Power-speed (P-V), underpin the Force-Power-Speed ​​profiles, characterized by the maximum mechanical capacities of the neuromuscular system of the lower limbs in various sports. This study focuses on soccer, where homogeneity in training is reflected, assuming that its athletes have the same conditions; a situation that does not favor the development and individual potential of each soccer player; therefore. The main objective of the research is to describe the effect of an individualized training plan, based on explosive strength (Strength-Speed) on the power of soccer players. A quantitative approach is used, with case study guidelines, with a sample of two young Chilean soccer players, who participated in individualized training plans; concluding that individualized work obtains benefits at levels of strength, contraction speed and greater muscular power, since the positive increase in the power levels of both young Chilean soccer players participating in the study is evident, thus favoring relevant qualities in this sport discipline. The results obtained contribute to the achievement of greater displacement (sprint) at the time of competing, reaching greater muscle tension and speed in them.
