“…This sits predominantly within the psychological domain of confidence conceptualization. Lelard and Ahmaidi (), however, solely review the evidence surrounding physical activity interventions to prevent falls. Both papers do acknowledge the wider multifactorial dimensions of falls and as such any concept of confidence must recognize each domain.…”

“…This is despite the referenced impact, both physically and mentally, throughout these studies. Examples of these range from fall interventions trials looking at balance and strength training; evaluation of frailty in home assessments; the use of technology; through to cognitive behaviour therapy (Doughty, Lewis, & McIntosh, ; Henderson, White, & Eisman, ; Jancewicz, ; Kutner, Barnhart, Wolf, McNeely, & Xu, ; Lelard & Ahmaidi, ; Oliver, ; Parry et al, , ).…”

A concept analysis of confidence related to older people living with frailty

Aim To describe and define a concept of confidence in the context of older people living with frailty, which is important to the worldwide healthy‐ageing agenda preventing decline in independence and well‐being. Design Concept analysis informed by Walker and Avant's eight‐stage approach. Methods Electronic databases (MEDLINE, CINAHL and PsychINFO) from 1994–2018 were searched. Published studies exploring confidence and excerpts of papers referencing older people, frailty and confidence informed the concept analysis. Extracted attributes informed model case and additional case development. Appraisal of antecedents, consequences and empirical referents informed the final concept's construction. Results Three overall defining attributes of confidence were identified in this concept analysis: physical, psychological and social. A central feature is personal control, influencing internal and external factors. These control factors can be enabling factors (positive factors) or dis‐enabling factors (negative factors), affecting the frail older persons overall physical health and mental well‐being.

“…It has often been suggested that physical activity improves functional ability in older people (Lord and Castell, 1994; Maki and McIlroy, 1996; Lelard and Ahmaidi, 2015). As an indicator of functional status, physically active olders show higher walking velocity compared to aged-matched sedentary adults.…”

During gait initiation, postural adjustments are needed to deal with balance and movement. With aging, gait initiation changes and reflects functional degradation of frailty individuals. However, physical activities have demonstrated beneficial effects of daily motor tasks. The aim of our study was to compare center of pressure (COP) displacement and ankle muscle co-activation during gait initiation in two physically active groups: a group of walkers (n = 12; mean age ± SD 72.6 ± 3.2 years) and a yoga group (n = 11; 71.5 ± 3.8 years). COP trajectory and electromyography of leg muscles were recorded simultaneously during five successive trials of gait initiation. Our main finding was that yoga practitioners had slower COP displacements (p < 0.01) and lower leg muscles % of coactivation (p < 0.01) in comparison with walkers. These parameters which characterized gait initiation control were correlated (r = 0.76; p < 0.01). Our results emphasize that lengthy ankle muscle co-activation and COP path in gait initiation differentiate yoga practitioners among physically active subjects.

“…It is important to emphasize that balance in the elderly can be affected by a combination of extrinsic factors (floor type, ground irregularities, physical barriers) and intrinsic factors, which are mainly associated with deficits in muscle strength (maximal strength and muscular power) (29) and postural control (dynamic and static balance). Despite the increases in muscle strength achieved by the PT, it is conjectured that unimodal exercises, performed in mechanical systems and explosively, were not able to significantly favor sensorial and proprioceptive mechanisms associated to the joint system that would confer greater stability and, consequently, would reduce the risk of falls (30,31) . Unlike the TUG, which involves task velocity, the Berg Scale tends to quantify maintaining postures and balance such as: standing unsupported with eyes closed, standing on only one support with eyes closed, reaching objects on the ground from the standing position, etc.…”

“…These findings lead to the theory about the benefits of multimodal exercises in functional capacity and risk of falls in the elderly, in which it is postulated that strength training concomitant with proprioceptive and walking activities would result in more significant and broad gains than isolated practices. (33,34) Programs aimed at the functionality and balance of the elderly should take into account not only the physical benefits, but also the individual taste, the economic and social limitations faced by the great majority of the elderly, and the possibility of accomplishing them in the community in which they live and in their homes seeking to increase adherence to such practices (31) . As for the emotional aspects, these were favored in both interventions, but significantly in the control group.…”

Introduction:The muscular strength exercises can be an effective intervention to prevent falls and to favor the functional capacity (FC) in the elderly. However, few studies have reported the benefits of power training (PT) and the subjective perception of the elderly on these activities. Objective: to evaluate the repercussions of a power training protocol on functional capacity and subjective health parameters in the elderly. Method: It was a prospective study involving 48 elderly people. Two groups were composed: a power training group (PG) with 22 participants with a mean age of 68.14 (5.46) years and the control group (CG) was composed of 32 elderly individuals aged 68.03 (4.83) years. Health-related quality of life was measured from the Medical Outcomes Study 36 -Item Short-Form Health Survey (SF-36). The FC was measured by the Berg Balance and Time Up and Go tests. The PT was performed 2x/week, with duration of 50 min/session, for 14 weeks (first two weeks of adaptation; first six weeks 3X/10-15 repetitions of 40-50% of the Subjective Perceived Exertion (SPE) / 6 following weeks 3X/6-10 repetitions of 60-70% of the SPE). The CG performed rhythm activities with the same frequency and weekly duration. Result: It was observed favorable results in FC after 14 weeks of power training. There was also a positive evaluation of most sf-36 domains, with emphasis on physical and emotional aspects. However, the perception of the elderly in relation to the pain domain presented negative results. Conclusion: The PT positively influenced the FC, the physical and the emotional aspects of the elderly; negatively affected the pain and maintained the low risk of fall after 12 weeks of intervention, without presenting intercurrences during the intervention.
