Abstract

Grip strength is a key physical capacity in judo due to its influence on opponent control, technical execution, and competitive performance. The aim of this study was to analyze the effects of a maximal strength endurance training program on grip strength in pre-juvenile judokas from the Guano Cantonal Sports League. A quasi-experimental design was employed with baseline, intermediate, and final assessments over a 16-week intervention period. The sample consisted of 20 athletes aged 15 to 17 years who participated in a structured training program with progressive loads aimed at strengthening the muscles of the hands and forearms. Grip strength was assessed using hand dynamometry following a standardized protocol. The findings revealed an increase in grip strength in both the dominant and non-dominant hands, with improvements exceeding 16% between the initial and final assessments. A sustained upward trend was also observed throughout the intervention period. It was concluded that maximal strength endurance training was an effective strategy for improving grip strength in pre-juvenile judokas, contributing to the development of sport-specific physical performance in this discipline.
