<dim:field element="description" qualifier="abstract" language="es-ES" mdschema="dc">El envejecimiento se asocia con disminuciones de la fuerza muscular y de la capacidad funcional, impulsadas por cambios neuromusculares y cardiovasculares. Además, se produce una reducción de la biodisponibilidad de óxido nítrico (NO), lo que puede afectar la función vascular y muscular. El objetivo de este estudio fue analizar los efectos de la ingestión aguda de 70 mL de zumo de remolacha rico en nitratos frente a un placebo sobre el rendimiento físico en mujeres sanas de entre 70 y 80 años. Nueve mujeres participaron en un ensayo aleatorizado, doble ciego y cruzado. La suplementación con zumo de remolacha produjo una mejora significativa en la fuerza isométrica de prensión manual de la mano dominante, pero no en la no dominante. No se observaron diferencias significativas en velocidad de marcha, prueba Timed Up-and-Go, potencia muscular de miembros inferiores, capacidad de marcha de seis minutos ni respuestas cardiovasculares.</dim:field>
<dim:field element="description" qualifier="abstract" language="en-GB" mdschema="dc">Aging is associated with declines in muscle strength and functional capacity, driven by both neuromuscular and cardiovascular changes. In parallel, ageing is accompanied by reduced nitric oxide (NO) bioavailability and potentially a reduced efficacy of the nitrate (NO₃⁻)–nitrite (NO₂⁻)–NO pathway, a route for NO generation that supports vascular and skeletal-muscle function. Thus, the aim of the present study was to examine the effects of acute ingestion of 70 mL of nitrate-rich beetroot juice (6.4 mmol NO₃⁻) versus 70 mL placebo (0.04 mmol NO₃⁻) on strength and functional performance in healthy older women aged between 70-80 years. Nine healthy women participated in this randomized, double-blind, placebo-controlled crossover experiment. Beetroot juice ingestion improved dominant handgrip strength but did not significantly affect walking performance, functional mobility, lower-limb power, cardiovascular responses, or six-minute walk performance compared with placebo.</dim:field>
