Specialists validation to aerobic resistance exercises group for soccer's category U-14/Validación por especialistas a grupo de ejercicios de resistencia aeróbica para futbolistas Categoría Sub-14

Abstract

Aerobic endurance in soccer is considered a determining capacity, for which its enhancement is an indispensable part of the content of sports training, being useful to design specialized models for its improvement, which must first be submitted to theoretical validation. In this sense, the objective of the research is to theoretically validate, through national and foreign experts, a proposal on a group of exercises to develop aerobic endurance in soccer players of the U-14 category. The research is descriptive-explanatory of correlational order, an intervention proposal is validated with a group of aerobic endurance exercises for U-14 soccer players in two moments of the design. Five evaluative indicators were consulted to 25 specialists (Nationals: 14, Foreigners: 11), and the future intervention proposal was theoretically validated. Between independent groups, there were no significantly different evaluations in any of the indicators5. Between related groups, significant differences in favor of the posttest were evidenced, both in the national specialists (Comprehensiveness: r=0.001; Affordability: r=0.002; Progression: p=0.001; Variety: p=0.001; Progressive Specialization: p=0.001), and in the foreign specialists (Comprehensiveness: r=0.006; Affordability: r=0.004; Progression: p=0.002; Variety: p=0.003; Progressive Specialization: p=0.004). The future intervention proposal presented adequate Comprehensiveness, Affordability, Progression, Variety and Progressive Specialization, significantly improving the evaluations of the proposal in its second moment of design. On the other hand, there is an adequate degree of agreement regardless of the theoretical and methodological conceptions of each independent group, an additional value of the proposal presented by the author.
