Effects of multicomponent exercise program with progressive phases on functional capacity,fitness, quality of life,dual-task and physiological variables in older adults: Randomized controlled trial protocol

IntroductionThe multicomponent exercise program must be carried out in phases, due to the low tolerance of the old adults to prolonged efforts, since their functional reserve is reduced.The aim of study is investigate the effects of Multicomponent on Progressive Phases Program on functional capacity, fitness, quality of life, dual-task and physiological variables in the elderly.MethodsThis is a randomized controlled trial protocol with blind examiners. The protocol was registered at clinictrials.gov (protocol number: NCT04118478). The experimental group will participate in a progressive multi-component program of 27 weeks divided into 3 phases of 9 weeks each of them. Primary outcomes will be determined by evaluating functional capacity using the Short Physical Performance Battery (SPPB), gait speed, and Time up and Go test. Fitness will be determined by the handgrip, 2-min step test, chair sit and reach test, and back scratch test. Quality of life will appear with the SF-36 questionnaire and dual-task with the walking-while-talking test. The physiological variables evaluated will be heart rate and blood pressure at rest, autonomic balance and forced spirometry. Secondary outcomes are determined by measuring the level of physical activity, motivation for exercise, and anthropometric variables.DiscussionThe results derived from this research will increase the knowledge about the effects of a program of this type. The possible discoveries could serve as a guide to encourage future researchers to develop similar protocols. The purpose of the program is to serve as a practical and viable tool for the benefit of older people.Clinical trial registry protocol: NCT04118478.     

Medida de la capacidad funcional y la calidad de vida relacionada con la salud de un grupo de personas mayores que llevan a cabo un programa de caminatas: estudio piloto

Introduction

This pre-experimental study analyses the Functional Capacity (FC), Body Mass Index (BMI), Health Related Quality of Life (HRQoL) and Health Capital Stock (HCS) of elderly people participating in a Walking program in Granollers (Barcelona).

Material and methods

One hundred and seventy-three participants were invited to participate. One hundred and one of them were users of the Municipal Program for Elderly People, and 72 received information by the communication media. One hundred and thirty-one (76.3%) of the participants completed the Program.The intervention consisted of a 6-month program, supervised by a specialist instructor once a week and controlled daily by a pedometer.The 6-minute walk test (6MWT) was analysed for the FC, and the EuroQoL for the HRQoL. The preferences derived from the EuroQoL scores and the Life Expectancy were used to calculate the FC. The monetary data were obtained using a fixed value.

Results

An increase in the average number of steps was observed after the program, especially in men. The results also showed a decrease in the BMI. The participants showed a improvement in overall health perception at the end of the program. The HCS scores confirmed the improvement in the HRQoL in men.

Conclusions

The Program was positive for increasing the number of steps and improving physical condition and health. The usefulness of the pedometer as a motivational tool of physical exercise is discussed.     

Valoración de la fuerza,la flexibilidad,el equilibrio,la resistencia y la agilidad en función del índice de masa corporal en mujeres mayores activas

Introduction

Overweight and obesity are increasing at an alarming rate among older people. This is mainly because this population is predominantly sedentary. The aim of this study was to classify, according to the body mass index (BMI), a group of older active women and to evaluate the different basic physical abilities as a function of this.

Material and methods

The BMI and fitness were evaluated in 60 elderly active women (mean age: 66.14 ± 6.59 years) using the 2-minute step test, arm curl test, chair stand test, back scratch test, chair-sit and reach-test, flamenco test, and 8-foot up-and-go test.

Results

It was found that 52.23% of the women studied had a normal BMI and 47.76% were slightly overweight. There were no cases of obesity or underweight. Women with normal BMI had better values in all tests than overweight women. Significant differences were found in the flamenco test (P < .05), and 8-foot up-and-go test (P < .01).

Conclusions

Older women who usually do physical activity had a normal or slightly overweight BMI. It was also found that women with lower BMI have better resistance, flexibility, balance and strength.     

Deterioro cognitivo y riesgo de caída en el anciano

Risk of fall is significantly increased in old people with cognitive decline due to specific associations between gait parameters and cognition. This association has recently been demonstrated, there being increasing evidence that cognitive domains such as attention, executive function and types of memory are critical for the correct regulation of gait. Gait disturbances can appear as early predictors of dementia in elderly patients. In the assessment of the fall risk, the use of dual tasks is novel, simple and relevant, especially in cognitive decline. Evidence for interventions in this population is limited, with vitamin D and physical exercise being the most encouraging, for decreasing the risk of fall in dementia.     

Revisión sobre el deterioro funcional en el anciano asociado al ingreso por enfermedad aguda

Hospitalization is a risk for elderly population, with a high probability of having adverse events. The most important one is functional impairment, due to its high prevalence and the serious impact it has on the quality of life. The main risk factors for functional decline associated with hospitalization are, age, immobility, cognitive impairment, and functional status prior to admission. It is necessary to detect patients at risk in order to implement the necessary actions to prevent this deterioration, with physical exercise and multidisciplinary geriatric care being the most important.     

Asociación entre la realización de ejercicio e indicadores de funcionamiento físico y cognitivo. Comparativa de resultados en función de la edad

Background

Gerontology research shows the importance of physical exercise for active aging. This study demonstrates the relationship between the practice of aerobic exercise, and physical fitness (muscle strength, respiratory capacity and motor speed) and cognitive performance (memory and visual-perceptual speed) and analyzes whether age is a modulating factor of this relationship.

Material and methods

The sample included 690 subjects with an age range of 30-85 years. The level of physical exercise was assessed using self-report form. Two sub-scales were used for the evaluation of cognitive performance: Digit Span Backwards and Digit Symbol (both are sub-scales of the Wechsler Adult Intelligence Scale - WAIS). The physical fitness was assessed using bio-behavioral measurements (strength, lung capacity, speed). To test the combined effect of exercise and age on the two variables (physical fitness and cognitive performance) two separate factorial analysis of variance were performed (procedure - general linear model: Univariate).

Result

The most significant result showed that scores on cognitive performance is a function of the intensity of the physical activity (F=4.8; P<0.002). With regard to physical fitness, its relationship with physical exercise is also significant (F=4.10; P<0.007) as well as the interaction between exercise and age (F=2.2; P<0.001).

Conclusions

The intensity in achieving aerobic exercise is associated with physical fitness and cognitive performance. Age has a specific weight in the association between exercise and physical fitness, this effect is higher in the older age groups (65-74 and 75-85 years for 30-49 and 50-64 years). These data suggest the compensatory effect of exercise on decline in old age.     

Efectos del ejercicio físico en la funcionalidad y calidad de vida en mayores institucionalizados diagnosticados de gonartrosis

Introduction

At present, aging and increased life expectancy implies a greater susceptibility to dependence, which then leads to the irreversible loss of quality of life, in many cases due to chronic diseases such as osteoarthritis (OA). The aim of this study was to determine the effect of a treatment based on aerobic exercise in institutionalised elderly people diagnosed with knee osteoarthritis.

Material and method

An experimental, prospective, single blind study was conducted. The sample (n = 31), was divided into two groups. The experimental group (n = 17) was treated based on aerobic exercise for 4 weeks with 2 sessions per week and each lasting 50 minutes. We conducted a pre-test and post-test assessment using a visual analogue scale, WOMAC questionnaire and SF-36 as measuring instruments. The statistical program SPSS15.0 was used for the analysis of the data.

Results

We obtained significant differences in the t-test for paired samples in the three dimensions of the WOMAC questionnaire, P<.001, in the perceived pain P<.001 and in the physical function, vitality and mental health dimensions of the SF-36 with a 95% confidence interval.

Conclusion

Exercise gave positive results in functional (pain, stiffness, physical function) and psychological aspects (mental health and vitality) in the institutionalised elderly.     

Modulación antioxidante y antiinflamatoria del ejercicio físico durante el envejecimiento

Aging is characterised by a gradual loss of the functional reserve. This, along with the fostering of sedentary habits and the increase in risk factors, causes a deterioration of antioxidant defences and an increase of the circulatory levels of inflammatory and oxidative markers, boosting a low-rate chronic inflammation, defined as inflamm-aging. This phenomenon is present in the aetiopathology of chronic diseases, as well as in cognitive deterioration cases associated with aging. The objective of this review is to describe the modulation of antioxidant and anti-inflammatory effects of physical exercise of moderate intensity and volume in the elderly. Evidence of its effectiveness as a non-pharmacological resource is presented, which decreases some deleterious effects of aging. This is mainly due to its neuroprotective action, the increase in circulating anti-inflammatory markers, and the improvement of antioxidant defence derived from its practice.
