| dc.description.abstract | Introduction: The farmer’s carry is a loaded‑carry exercise in which an individual walks a distance while holding heavy loads in each hand, requiring substantial grip strength, whole‑body stability, and coordinated lower‑limb force production. Objective: This study aimed to examine the acute effects of a light‑load inclined farmer’s carry protocol on grip strength, rectus femoris muscle mechanical properties, and lower‑limb asymmetries. Methodology: Twelve healthy young adults completed a continuous treadmill walk at 4 km/h while carrying two 10kg dumbbells, progressing through five incline stages (0–8%), each corresponding to 50 meters. Grip strength and muscle mechanical properties were recorded after each stage during a 1‑minute rest. Results: Significant grip strength reductions were observed in both hands, with decreases of 10.10% in the dominant side (p < 0.05, η²p = 0.61) and 8.50% in the non‑dominant side (p <0.05, η²p = 0.41). Also, a significant decrease in logarithmic decrement was detected in the dominant side (p = 0.04, W = 0.19). At baseline, 0, 2 and 6% were also observed significant differences between the dominant side and non-dominant side in logarithmic decrement. Conclusions: Overall, inclined farmer’s carry efforts primarily induced peripheral, grip‑specific fatigue, with minimal alterations in rectus femoris muscle mechanical properties, supporting the use of inclines to safely increase task difficulty without excessive mechanical stress. | eng |
| dc.description.abstract | Introducción: El farmer’s carry es un ejercicio de transporte de cargas que requiere fuerza de prensión, estabilidad global y producción coordinada de fuerza de los miembros inferiores. Objetivo: Este estudio analizó los efectos agudos de un protocolo de farmer’s carry inclinado con cargas ligeras sobre la fuerza de prensión manual, las propiedades mecánicas del recto femoral y las asimetrías de los miembros inferiores. Metodología: Doce adultos jóvenes sanos realizaron una caminata en cinta rodante a 4 km/h transportando dos mancuernas de 10 kg. El protocolo incluyó cinco etapas de inclinación (0–8%), correspondientes a 50 metros cada una. Tras cada etapa, durante un descanso de 1 minuto, se evaluaron la fuerza de prensión y las propiedades mecánicas musculares. Resultados: Se observaron reducciones significativas de la fuerza de prensión en ambas manos, con disminuciones del 10.10% en el lado dominante (p < 0.05; η²p = 0.61) y del 8.50% en el lado no dominante (p < 0.05; η²p = 0.41). También se detectó una disminución significativa del decremento logarítmico en el lado dominante (p = 0.04; W = 0.19). Además, se observaron diferencias entre ambos lados en baseline y en las inclinaciones de 0, 2 y 6%. Conclusiones: El farmer’s carry inclinado indujo principalmente fatiga periférica específica de la prensión, con mínimas alteraciones en las propiedades mecánicas del recto femoral, apoyando el uso de inclinaciones para aumentar la dificultad de la tarea sin excesivo estrés mecánico. | spa |
