SALAZAR, María Clara Rodríguez  and  BALLESTEROS, Ángela Patricia Valero. Effect of an ACT Intervention on Aerobic Endurance and Experiential Avoidance in Walkers. Rev. Costarric. Psic [online]. 2015, vol.34, n.2, pp.96-111. ISSN 1659-2913.

The purpose of the present study was to identify the effect of an Acceptance and Commitment intervention Therapy (ACT) on aerobic endurance and experiential avoidance behavior of a group of walkers in Bogota. This study used a pretest-posttest design with a control group. The sample consisted of ten walkers of either sex, with an average age of 16.70 years, and a range between 15 and 20 years old, belonging to the Bogotá Athletics League. The participants were chosen as a conveniente sample. The instruments used were the 3000-meter test and the Acceptance and Action Questionnaire (AAQ). The ACT intervention was conducted in four sessions, where they developed the contents defined by the authors of this intervention (Wilson and Luciano, 2002). Non-parametric statistics were used for data analysis, by means of the Mann-Whitney U. The posttest results indicate a greater aerobic resistance in the 3000-meter test for the test group in comparison to the control group. Likewise the experimental group shows a greater acceptance for negative internal events.
