Descrizione dettagliata

This study was a single-blind (assessors), randomized controlled trial with parallel groups, comparing the effects of MCT and EBT. Both groups participated in structured physical activity interventions following a quantitative methodological approach. Participant allocation (ratio 1:1) was performed using an online randomization tool (https://www.randomizer.org) by an investigator not involved in assessments. The methodology followed the CONSORT (Consolidated Standards of Reporting Trials) guidelines for randomized clinical trials (Turner et al., 2012). The study was registered in the U.S. ClinicalTrials.gov (registration ID: NCT0678002). The interventions lasted 16 weeks and were conducted twice per week on non-consecutive days: Mondays and Wednesdays for the EBT group, and Tuesdays and Thursdays for the MCT group. Each session lasted 60 minutes. The assessed outcomes included general physical fitness (Chair stand, Arm curl, 2-minute step test, Chair sit-and-reach, Back scratch, TUG, and MIHS for dominant and non-dominant sides), postural balance variables (energy and center of pressure velocity in medio-lateral and antero-posterior directions) under eyes-open and eyes-closed conditions and HRQoL. All assessments were performed in the afternoon (between 4:00 p.m. and 6:00 p.m.) in a temperature-controlled laboratory, using standardized evaluators to ensure consistency between pre- and post-intervention measurements. During the intervention period, no participants experienced musculoskeletal or cardiorespiratory injuries, and no pain was reported either prior to the assessments or during the training sessions.

Intervento / Trattamento
Comparatore attivo: Elastic band training program
EBT was implemented based on previous studies demonstrating its safety and effectiveness for older women. The elastic bands (Ultimate Elastic Resistance Band System Elite, country) was used during the intervention. The elastic bands were color-coded (yellow, red, green, and black), with each color representing a different resistance level used to prescribe and adjust training load.
Comportamentale: Elastic band training program
The training program included resistance exercises targeting the major muscle groups of both the upper and lower limbs. Upper-limb exercises consisted of let pulldown, scapular retraction, shoulder abduction, biceps curl, triceps extension, and upright row. Lower-limb exercises included leg press, ankle eversion, ankle dorsiflexion, knee extension, knee flexion, and hip flexion. Participants initiated the program using the lowest resistance level, with progressive increases in training volume throughout the intervention. The progression of training volume followed the same periodization used in the MCT group. During weeks 1 to 4, participants performed three sets of 10 repetitions per exercise with 2-minute rest intervals between sets. Between weeks 5 and 8, volume increased to four sets of 10 repetitions, maintaining the same rest interval. During weeks 9 to 12, participants performed four sets of 12 repetitions, and during weeks 13 to 16, the same volume (4 × 12 repetitions) was main
Sperimentale: Multicomponent training program
The MCT main phase consisted of a strength training circuit targeting the major muscle groups of the upper limbs (biceps, triceps, deltoids, and latissimus dorsi) and lower limbs (quadriceps, hamstrings, gluteus, and gastrocnemius). The circuit also incorporated exercises designed to improve cardiorespiratory fitness, agility, and postural balance, including both static and dynamic balance tasks. Exercises were performed using body weight and external implements, such as dumbbells, kettlebells, poles, and medicine balls.
Comportamentale: Multicomponent training program
During weeks 1 to 4, participants performed three sets of 10 repetitions per exercise with a 2-minute rest interval between sets. Movements were executed at a controlled tempo of approximately 2 seconds during the concentric phase and 4 seconds during the eccentric phase. Between weeks 5 and 8, training volume increased to four sets of 10 repetitions per exercise, maintaining the same rest interval. During weeks 9 to 12, participants performed four sets of 12 repetitions. Finally, during weeks 13 to 16, the training volume (4 × 12 repetitions) was maintained while the rest interval was reduced to 90 seconds in order to increase the training stimulus. Strength training intensity was monitored using the OMNI-Resistance Exercise Scale of Perceived Exertion (Lagally & Robertson, 2006; Petro et al., 2025), with participants maintaining perceived exertion values between 5 and 8, corresponding to moderate-to-vigorous intensity.

Physical fitness
Lasso di tempo: 16 weeks
The Senior Fitness Test was assessed, which provides an evaluation with excellent reliability and easy application. The tests were performed in the following order. The chair stand test was conducted as the initial test in the battery to determine lower limb muscle strength, and the number of repetitions completed in 30 seconds was recorded. The second test was the arm curl test, which measured upper limb muscle strength by counting the number of repetitions completed in 30 seconds while holding a 1.4 kg (3 lb) dumbbell. Then, the 2-minute step test was performed to assess cardiorespiratory fitness, counting the number of knee elevations achieved by each participant, reaching at least a 70-degree angle at the hip joint. Lower limb flexibility was measured in centimeters during the chair sit-and-reach test. The back scratch test was conducted to measure upper limb flexibility, recorded in centimeters. The TUG test was performed to assess agility and dynamic balanc

Go/No-Go task
Lasso di tempo: 16 weeks
Motor inhibition was assessed using a computerized Go/No-Go task administered individually in a quiet, temperature-controlled laboratory environment with standardized lighting conditions. Participants wore noise-cancelling headphones to minimize external distractions. The task was implemented using OpenSesame software and presented on a monitor positioned approximately 60 cm from the participant. Visual stimuli consisted of colored circles (blue and yellow) displayed randomly within a fixed central area on the screen. Participants were instructed to respond as quickly as possible to Go stimuli by pressing the space bar on a keyboard and to withhold their response when a No-Go stimulus appeared. The stimulus-response mapping was counterbalanced across participants to control for potential color-related biases. Feedback for incorrect responses was provided through a brief visual signal displayed at the center of the screen. The task comprised a total of 160 trials
16 weeks
Cognitive status
Lasso di tempo: 16 weeks
Cognitive status was evaluated using the memory, phonetic fluency, and temporal-spatial orientation (by its Spanish acronym, MEFO) survey, a brief and clinically validated screening instrument designed to assess global cognitive status in older people . The MEFO comprises three core domains: episodic memory, assessed through delayed recall tasks; verbal fluency, typically evaluated via category-based word generation; and temporal-spatial orientation, which examines awareness of time-related information. These components are integrated into a composite score that reflects overall cognitive status. Higher scores indicate better cognitive functioning.

Postural balance
Lasso di tempo: 16 weeks
Static postural balance was objectively assessed using a posturographic platform (Artoficio, model Rev0610, Chile), which incorporates load sensors to quantitatively record center of pressure (COP) oscillations. The sampling rate was set to 40 Hz. The following postural balance variables were analyzed: energy, medio-lateral center-of-pressure velocity (ML speed), and antero-posterior center-of-pressure velocity (AP speed), each assessed under eyes-open (EO) and eyes-closed (EC) conditions. Participants were instructed to step onto the platform and maintain a stable foot position without adjusting their stance throughout each trial. Foot position was standardized across participants. Individuals were instructed to stand barefoot with feet placed parallel and hip-width apart (approximately at the level of the anterior superior iliac spines), with heels aligned along a predefined reference line marked on the platform surface. The assessment consisted of three consecutive 30-second condit

Health-related quality of life
Lasso di tempo: 16 weeks
This questionnaire was applied using the Short Form Health Survey (SF-36) second version. It evaluates eight health dimensions: physical function, physical role, body pain, general health, vitality, social function, emotional role, and mental health. The score is obtained by summing the responses, ranging from 0, representing the poorest health status, to 100, representing the best health status
