Vicia Faba Peptides and Resistance Training in the Elderly

This randomized, double-blind, placebo-controlled clinical trial aims to investigate the effects of supplementation with peptides derived from Vicia faba L. combined with supervised resistance training in physically active and inactive older adults. Approximately 100 adults aged 60 years or older will be enrolled. Participants will first be classified as physically active or inactive according to their habitual physical activity level and will then be randomly assigned to receive either Vicia faba L.-derived peptides (2.5 g/day) or placebo. All participants will complete the same supervised resistance training program three times per week for four weeks and will receive nutritional monitoring. Assessments will be performed before and after the intervention to investigate changes in muscle strength and power, body composition, functional mobility, postural balance, physical function, frailty, mental health, quality of life, and cognitive performance. The study will also examine whether habitual physical activity level influences the responses to the combined supplementation and resistance training intervention.
