About this study

Official title: Investigation of the (Potential) Therapeutic Effects of Vicia Faba L. Peptides Combined With Resistance Training on the Strength, Function, and Body Composition of Physically Active and Inactive Older Adults: A Randomized, Double-Blind, Placebo-Controlled Clinical Study

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Vicia faba L.-derived peptidesDietary supplement

    Participants assigned to the experimental intervention will receive 2.5 g/day of Vicia faba L.-derived peptides for four weeks. The supplement will be administered once daily as a powder using a measuring scoop containing the prescribed dose and diluted in 300 mL of drinking water. Participants will consume the supplement at home every day, including weekends. Containers will be returned at the end of the intervention to assess adherence.

  • PlaceboDietary supplement

    Participants assigned to the placebo intervention will receive silicified microcrystalline cellulose once daily for four weeks. The placebo will be administered as a powder diluted in 300 mL of drinking water and will be standardized to match the mode of presentation and administration of the experimental supplement. Participants will consume the placebo at home every day, including weekends. Containers will be returned at the end of the intervention to assess adherence.

  • Supervised Resistance TrainingBehavioural

    All participants will complete a supervised resistance training program for four weeks, with three sessions per week performed on non-consecutive days. The program will target the major muscle groups of the upper and lower limbs using resistance-training equipment, free weights, and other available implements. Exercise prescription will be individualized according to each participant's functional capacity, previous experience, and clinical limitations. Training loads will be progressively adjusted throughout the intervention according to individual progress and exercise tolerance.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Fat-Free Mass (kg)

    Change in fat-free mass following the 4-week intervention. Fat-free mass will be assessed using multifrequency bioelectrical impedance analysis (InBody 570) under standardized pre-assessment conditions. Fat-free mass will be expressed in kilograms (kg).

    Measured: Baseline and after 4 weeks of intervention

Secondary outcomes (11)
  1. Change in Handgrip Strength (kgf)

    Change in handgrip strength. Handgrip strength will be assessed using a hydraulic hand dynamometer. Three measurements will be performed for each hand, with approximately 30 seconds of rest between attempts. The mean of the three measurements will be used for analysis, and results will be expressed in kilograms-force (kgf).

    Measured: Baseline and after 4 weeks of intervention

  2. Change in Maximal Voluntary Isometric Contraction and Muscle Power during Knee Extension and Flexion

    Maximal Voluntary Isometric Contraction (MVIC) and Muscle Power during Knee Extension and Flexion will be assessed using a Biodex Multi-Joint System dynamometer. Muscle power during concentric knee flexion and extension will be evaluated at angular velocities of 60°/s and 180°/s. MVIC will be measured across 3 attempts, with a 1-minute resting interval, with the knee flexed at 90°. Outcome for MVIC will include peak torque (N·m), while outcome for muscle power will consist in total work done.

    Measured: Baseline and after 4 weeks of intervention

  3. Change in Lower-Limb Strength Endurance (repetitions)

    Lower-limb strength endurance will be assessed using the 30-Second Chair Stand Test. The outcome will include the total number of complete sit-to-stand repetitions performed within 30 seconds.

    Measured: Baseline and after 4 weeks of intervention

  4. Change in Upper-Limb Muscle Power (meters)

    Upper-limb muscle power will be assessed using the Seated Medicine Ball Throw Test. With the bench standing in 45°, participants will throw a medicine ball (3 kg for men, 2 kg for women) forward from a seated position using a chest-pass movement. Throwing distance, in meters, will be measured from the starting point to the point where the ball first contacts the floor.

    Measured: Baseline and after 4 weeks of intervention

  5. Change in Dynamic Balance

    Dynamic balance will be assessed using the Instrumented Timed Up and Go (iTUG) test with the Baiobit inertial sensor system. Outcomes will include total completion time (in seconds) and kinematic parameters related to the different phases of the task.

    Measured: Baseline and after 4 weeks of intervention

  6. Change in Self-Reported Functional Disability

    Self-reported functional disability will be assessed using the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0), an instrument developed by the World Health Organization for the cross-sectional measurement of functional disability, applicable to any health condition. Scores will be calculated according to the World Health Organization technical manual using the simple scoring method, in which raw scores for each domain are summed and subsequently transformed into a 0-100 point scale, where higher values indicate a greater level of disability.

    Measured: Baseline and after 4 weeks of intervention

  7. Change in body fat percentage

    Change in body fat percentage, in percent, will be assessed using multifrequency bioelectrical impedance analysis (InBody 570) under standardized pre-assessment conditions.

    Measured: Baseline and after 4 weeks of intervention

  8. Change in Vastus Lateralis and Rectus Femoris Muscle Thickness (cm)

    Change in Vastus lateralis and Rectus Femoris Muscle Thickness will be assessed by ultrasonography of the dominant limb at 30 and 70% of the distance from the greater trochanter of the femur and the lateral femoral condyle. Muscle thickness will be measured in centimeters.

    Measured: Baseline and after 4 weeks of intervention

  9. Change in Physical Frailty Phenotype

    Physical frailty will be assessed using the Fried Frailty Phenotype, which includes five components: unintentional weight loss, self-reported exhaustion, reduced handgrip strength, slow walking speed, and low physical activity level. Participants will be classified as non-frail, pre-frail, or frail.

    Measured: Baseline and after 4 weeks of intervention

  10. Change in Intensity of Depressive Symptoms

    Change in the intensity of depressive symptoms will be assessed using the Beck Depression Inventory - Second Edition (BDI-II), a self-report instrument widely used to measure the severity of depressive symptoms and validated for the Brazilian population. The questionnaire consists of 21 items, each containing four options graded from 0 to 3 points, reflecting the increasing intensity of symptoms over the past two weeks. The total score ranges from 0 to 63 points, with higher scores indicating greater severity of depressive symptoms. To interpret the results, the following conventionally used cut-off points will be adopted: 0-13 (minimal), 14-19 (mild), 20-28 (moderate), and 29-63 (severe).

    Measured: Baseline and after 4 weeks of intervention

  11. Change in Quality of Life

    Change in Quality of life will be assessed using the World Health Organization Quality of Life-OLD (WHOQOL-OLD). The instrument consists of 24 questions distributed across six facets: Sensory Functioning, Autonomy, Past/Present/Future Activities, Social Participation, Death and Dying, and Intimacy. Each facet comprises four questions, resulting in a multidimensional assessment of quality of life related to aging. Responses are recorded on a five-point Likert scale (ranging from 1 to 5) based on the degree of intensity, satisfaction, frequency, or agreement associated with each question. Initially, the values obtained for each facet will be summed, followed by the transformation of the scores onto a 0-100 scale, allowing for better interpretation and comparison of results across participants and different assessment time points. On this transformed scale, higher values will indicate a better perception of quality of life.

    Measured: Baseline and after 4 weeks of intervention
