Relación entre potencia y resistencia en jugadores sub-20 de fútbol
The objective of this research was to determine the correlation that exists between the power and resistance to speed in soccer players of the Sub-20 category of the professional team Patriotas Boyacá. Using an analytical empirical approach and a non-experimental correlational descriptive design, with a sample of 18 players aged 18.61 ± 0.9 years, weight 70.55 ± 6.6 Kg, height 178.5 ± 8.7 Cm and a BMI of 22.13 ± 0.1%. The Bosco test was applied to them in the Abalakov (ABK), Counter Mouvement Jump (CMJ) and Squat Jump (SJ) and the Sprint Repeat Ability (RSA) tests, in order to analyze the study variables. For the statistical analysis SPSS v.22.0 (IBM Company Chicago) was used, performing the Pearson correlation coefficient (r) parametric data and an Alpha greater than or equal to 0.05.From the results obtained from the Bosco test in height, data was found in SJ 38.4 ± 3.35 cm; in ABK 45.4 ± 4.03 cm, and,for CMJ 38.5 ± 4.82 cm. On the other hand, the results for the RSA test indicate that the fatigue index of athletes obtained an average of 7.514 ± 4.08%. The data showed results in the demonstration that there is no correlation between the ABK takeoff and the RSA power (p=0,015); while the takeoff of the SJ and CMJ jumps if they are related to the power of the RSA test (p = 0.056) (p = 0.688) respectively. Additionally, it is concluded that there is a relationship between the fatigue index, the best sprint in the RSA test and the power of the RSA test (p = 0.026).
