Background and Purpose: The real benefits of stretching when used as training for the older adult population and for developing other physical capacities are still uncertain. Thus, the objective of the present work is to investigate the effects of stretching training combined with multi-component training on the physical capacities of physically inactive older women. Methods: Women aged 60 to 70 years were randomized into three groups: multicomponent training (MT), multicomponent training combined with flexibility training (CT), and control group (CG). Both training interventions were carried out for 14 weeks, with two weekly sessions. Participants were assessed for agility, muscle strength (sitting and standing and elbow flexion/extension), and cardiorespiratory fitness (6-min walk). Results and Discussion: Multicomponent training with flexibility presented a very large effect on the variables of strength, agility, and aerobic fitness, while multicomponent training had a medium effect on agility and a large and very large effect on muscle strength variables. This is the first study in the literature to analyze the effect of flexibility training, associated with multicomponent training, on other physical capacities. Conclusions: The results of the current study suggest that adding flexibility training to a multicomponent training program generates additional benefits to the development of other physical capacities.

Background: Multicomponent training has considerable adherence among older populations, but there is a lack of literature on the benefits of this training on older people’s posture. Literature also lacks stretching protocols that work the body in an integrated/unified way and respect the principle of individuality in exercise training. We evaluated the effect of a multicomponent training protocol combined or not with flexibility training in improving the posture and quality of movement in physically inactive older women, according to a score lower than 9.11 in the Modified Baecke Questionnaire for the Elderly (MBQE). Methods: 142 participants were evaluated and randomized in three training groups: multicomponent training (MT = 52), multicomponent and flexibility training (MFT = 43), and a control group (CG = 47). We evaluated joint amplitude using goniometry, flexibility with sit and reach and hands behind the back tests, quality of movement with the functional movement screen, and posture using biophotogammetry. Results: The MFT group had 15 parameters—flexibility and posture—with a very large effect size (ES > 1.30) and nine with average ES (0.50–0.79). MT presented two variables with large ES (0.80–1.25) and seven with average ES. CG presented three variables with high ES and five with average ES. Both interventions improved the quality of movement. Conclusions: These results demonstrate that 14 weeks of multicomponent and flexibility training in a group intervention can improve flexibility and posture levels in physically inactive older women.
