Fortalecimiento del core y su incidencia en el mejoramiento de la resistencia en carreras de larga duración

Abstract

The present investigation was carried out in the De la Madre Park, located in the city of Cuenca, Azuay province. The objective of the study was to analyze the strengthening of the core and its incidence in the improvement of endurance in long-term races, in runners aged 18 - 45 years who train in the athletics club "Morlacos Running Club". For the development of the study, a training program was developed and applied to 20 athletes who train for long-term athletic events. Participants were selected according to inclusion criteria. The program was applied for 8 weeks, three days a week, after the usual training sessions, with a day of rest between sessions. This study is quasi-experimental without a control group. The main variables used for this research were the strengthening of the core and the improvement of time resistance; the secondary variables were: age, body mass index, training time. The physical performance of the athletes was evaluated through a pre-test and post-test, which consisted of traveling a distance of 10km in the open air on a 400m track. For the data analysis, the IBM SPSS Statistics 22 computer software was used. The Shapiro-Wilks test was also used in order to check the normality of the data, the Student's t test for paired samples for the level of significance between the pre-test and post-test and a linear regression was performed to examine the influence of the secondary variables on the result. The results obtained showed a significant difference p <0.05 of 1’15” of the post-test versus the pre-test for the distance of 10Km. Therefore, the application of a core training program for 8 weeks, 3 times a week, evidenced an improvement in endurance for longterm athletic races.
