Item FUERZA DE AGARRE Y SU RELACIÓN CON LA RESISTENCIA MUSCULAR EN DEPORTISTAS DE CONTACTO(2026-01-27) Aguayo Toro, Karen Anahí; Bonilla Ayala, Josselyn Gabriela; Universidad Técnica de Ambato / Facultad de Ciencias de Salud / Carrera de FisioterapiaThe present study, entitled “Grip strength and its relationship to muscular endurance in contact sports athletes,” aimed to determine the relationship between hand grip strength and upper limb muscular endurance in 40 contact sports athletes from the Cotopaxi Sports Federation, aged between 14 and 17 years. A quantitative, correlational, cross-sectional approach was used. Grip strength was assessed using a Jamar hydraulic dynamometer, while muscular endurance was measured through push-ups and pull-ups. The results showed that the average grip strength of the right hand was 27.89 kg and that of the left hand was 25.48 kg, highlighting a lateral dominance in the right hand. In terms of muscle endurance, the athletes achieved an average of 30 repetitions in the push-up test and 4 repetitions in the pull-up test, demonstrating greater performance in pushing exercises. Statistical analysis was performed using Spearman's Rho coefficient, obtaining a positive and significant correlation between grip strength and performance in the pull-up test (ρ = 0.635 right; ρ = 0.642 left; p < 0.001), while no significant correlation was found with the push-up test. These results demonstrate that greater grip strength promotes the ability to sustain repetitive efforts, making it an important indicator of functional performance in combat sports. It can therefore be concluded that grip strength is related to upper limb muscle endurance, highlighting its decisive role in athletic performance.
