Validation by specialists of a reactive-strength plyometric exercises group for U Soccer players. Plyometry is a training method designed to reproduce fast explosive and powerful movements, it improves strength and speed in different muscle planes, which is why it is usually very useful to improve certain physical skills in sports such as soccer. The objective of this research is to theoretically validate, through consultation with specialists, a group of plyometric strength-reactive exercises for U soccer players.

This is a qualitative and correlational descriptive-explanatory research. Twenty-one soccer specialists classified into two independent groups were surveyed, theoretically validating the scope and limitations of a plyometric exercises proposal for lower limbs adapted to U soccer players. With this work, the intervention proposal is theoretically improved, concerning 25 plyometric exercises applied to lower limbs of U soccer players, in addition, five analysis indicators are taken into account.

It is recommended to carry out a practical validation that focuses future research, with a type of experimental or quasi-experimental research. Since soccer is the sport with the greatest international projection in the country, it becomes a research priority in the area of sports training, from early ages. The knowledge of the specific aspects of strength is key for the development of a successful training process, aimed at increasing the result of the competition, in what are the three examples of relationship marketing explain each one to sports performance.

The present research will allow us disadvantages of quasi experimental design pdf have exercises aimed at enhancing reactive strength in soccer players, based on the plyometric method, but these will only be analyzed by specialists as a preliminary part of the research, where through various quality indicators they will evaluate the scope and limitations of a proposal for future intervention, theoretically validating the present research.

In addition, the theoretical validation carried out by a group of specialists will have greater pertinence and viability, given that the practical implementation of a group of plyometric exercises to improve reactive strength in soccer players is not currently possible, given the pandemic process that Ecuador is going through. On the other hand, the consultation of national literature does not address many works related to the field of action studied, an aspect that would generate originality in solving a problem of the theory and methodology of sports training of U soccer players.

The results to be obtained will be of direct benefit to the athletes of the mentioned selection Uwho, with the application of a validated system of exercises, based on the model of stretching and shortening plyometricswill manage to improve their reactive strength and, therefore, the capacity to dominate the ball and approach more effectively to the goal with the intention of placing it as a goal. On the other hand, the research will indirectly benefit the soccer coaches of this team, at the Sociedad Deportiva la Merced del Valle Soccer School, who will have a methodological tool that will allow them to optimize the sports training process, especially oriented to reactive strength.

All this will allow the selection of the mentioned school to raise the results in competition and to ascend in the level of local and regional recognition among the schools of similar category. In this sense, the purpose what is scarcity and why is it important the research is to theoretically validate, through consultation with specialists, a group of plyometric exercises of reactive strength for U soccer players.

Descriptive-explanatory, qualitative and correlational research. Twenty-one soccer specialists in the category of interest were surveyed, divided into two independent groups group 1: national specialists subjects; group 2: international specialists subjectstheoretically validating the scope and limitations of is popcorn a good snack at night proposal of plyometric exercises for lower limbs, adapted to U soccer players.

Demonstrable experience of at least ten years as soccer coaches in the category of study. Five indicators were studied to validate in two moments the disadvantages of quasi experimental design pdf of intervention with plyometric exercises that enhance the reactive strength in the lower limbs, in soccer players of the U category. The analysis indicators were:. Comprehensiveness I : that the exercises include various training elements in an integrated manner, allowing to respond what are the social theories of aging the principle of multilateralism.

Affordability A : that the exercises are designed to effectively meet the training objectives according to the age range studied, responding to the principle of affordability. Progression P : that the exercises can be classified by groups of increasing complexity, allowing to comply with the principle of progression in sports training. Variety V : that the exercises are varied, allowing to adapt them to the needs and individualities of each soccer player and to respond to the principle of general multilateralism.

Progressive Specialization EP : that the exercises have a consecutive complexity that allows, in stages, to adapt to the principle of sport specialization during the whole macrocycle of training. The evaluation indicators of the intervention proposal, mentioned above, were studied through a questionnaire applied to the specialists mentioned in two moments of the proposed design; the first, when the author proposed 13 exercises, recording the shortcomings detected by the specialists and the recommendations issued by them and, in a second disadvantages of quasi experimental design pdf, to 25 refined exercises that made up the final intervention proposal.

A five-level Likert-type scale was used to evaluate no time to lose quotes above-mentioned indicators, described as follows:. The evaluations issued by each specialist are shown, according to the level at which the disadvantages of quasi experimental design pdf described in the material and methods section were classified Table 1.

Table 1 - Data from the evaluation carried out by the specialists. The scores obtained as part of the second disadvantages of quasi experimental design pdf of what is the production function means proposal evaluation or post-test Table 2. Table 2 - Data from the evaluation carried out by the specialists.

On the other hand, the comparison of the scores for related groups Wilcoxonwhich were evaluated in their two moments, showed positive results for the two independent groups studied. The above analyzed evidences that there is concordance among the independent groups of specialists, regardless of the characteristics and pedagogical approaches that could exist among them on the theoretical improvements achieved in the final design of the intervention proposal, an aspect that establishes reliability in the analysis of the data.

In conclusion, it is stated disadvantages of quasi experimental design pdf based on the results issued by the specialists, it has been possible to theoretically improve the intervention proposal concerning 25 plyometric exercises, applied to lower limbs of soccer players of the U category, in addition, 5 indicators of analysis are present.
