Factors associated with impaired functional performance in elderly women in primary health care

Objective: To identify the factors associated with functional performance, as well as to compare anthropometric, metabolic and inflammatory parameters according to the functional performance of elderly women in primary health care. Method: Two hundred and four elderly women (68.36 ±6.18 years) took part. Functional performance was considered impaired when the Timed Up and Go (TUG) test result was >12.47 seconds. Results: 116 elderly women had impaired functional performance (56.86%). They were older, had higher BMI, WC, WHtR, %BF and IL-6, worse cognitive performance and lower muscle strength (MS). Initially, age >70 years, FM <20Kg, WHtR ≥57cm, and IL-6 ≥18pg/mL were associated with impaired functional performance (OR=1.977; 95%CI=1.095-3.570; OR=2.935; 95%CI=2.663-5.274; OR=2.455; 95%CI=1.093-5.511; OR=2.663; 95%CI=1.503-4.718). In the logistic regression, IL-6 ≥18pg/mL and FM<20Kg remained associated with impaired functional performance (OR=2.540; 95%CI=1.383-4.665; OR=2.479; 95%CI=1.341-4.582). Conclusion: FM and inflammatory parameters should be considered in the context of the functional performance of elderly women in primary health care.

Pilates Exercises Improves Anticipatory Muscular Activation in Elderly Women: A RCT Study

Aims: to investigate the effects of Pilates exercise on the anticipatory activation of selected lower limb muscles and balance in elderly women who had previous history of falling. Methods: In this randomized clinical trial study, 22 elderly women were divided into the control (n = 10) and the experimental (n = 12) groups. The Berg balance scale and Timed Up and Go Test and electrical activity of selected lower-limb muscles were collected before and after the intervention period. The experimental group performed the Pilates exercises for eight weeks (three sessions of one hour per week). Results: Pilates exercises had a significant effect on the Berg balance scale (p = 0.001), the timed up and go test (p < 0.001), the onset time of the tibialis anterior (p < 0.001), vastus lateralis (p = 0.004), vastus medialis (p = 0.033), and biceps femoris (p = 0.001). Conclusion: Pilates exercises can improve anticipatory activation of lower extremity muscles, balance and performance in elderly women with falling history.

Gait speed and functional performance in elderly women with knee osteoarthritis

Abstract Introduction: Knee osteoarthritis is a degenerative and inflammatory disease that causes skeletal muscle dysfunction and induces limitation of functional activities, such as gait. Objective: To assess the relationship between gait speed and functional performance in elderly women with knee osteoarthritis. Methods: 38 elderly women were divided into two groups: knee osteoarthritis group (KOAG) (n = 24, 68 ± 4.42) and control group (CG) (n = 14, 66.35 ± 3.54). Gait speed data was assessed through Qualisys system and functional performance through a checklist of the International Classification of Functioning, Disability and Health (ICF). Results: Comparing with CG (p &lt; 0.05), KOAG patients had lower gait speed (p = 0.004) and worse functional performance in d4500 (walking short distances), d4501 (walking long distances), d4502 (walking on different surfaces), and d4503 (walking around obstacles) ICF categories. By associating gait speed and functional performance in KOAG, significant differences were found in the d4500 (p = 0.019) and d4501 (p = 0.035) categories, but none for either the d4502 (p = 0.511) or d4503 (p = 0.076) categories. Gait speed was negatively correlated with d4500 (rho = -0.585, p = 0.003), d4501 (rho= -0.552, p = 0.005), and d4502 (rho = -0,548, p = 0,006). Conclusion: Gait speed is related to functional performance in elderly women with knee osteoarthritis for the activities of walking short distances, walking long distances, and walking on different surfaces. However, it seems that gait speed is not related to walking around obstacles.

Photobiomodulation (PBM) Therapy on Muscle Performance in Elderly Women

Contribution of lower limb muscle strength to walking, postural sway and functional performance in elderly women

BACKGROUND: Aging-related deterioration of the lower limb muscle strength could highly influence the functional performance of elderly individuals. OBJECTIVE: To investigate how advancing age impacts the lower limb muscle strength and consequently affects the balance and walking performance. METHODS: Twenty-seven community-dwelling elderly females underwent isokinetic ankle dorsi/plantar flexion (ADF/APF), inversion/eversion (AIN/AEV), knee flexion/extension (KFL/KEX), hip flexion/extension (HFL/HEX), and abduction/adduction (HAB/HAD) tests, the six-minute walk test, open-eyed biped balance test on foam rubber and the performance-oriented mobility assessment (POMA). RESULTS: The Pearson’s product-moment correlation coefficients demonstrated that advancing age negatively influenced the relative work and moment produced in all the muscle groups, the POMA score (r=-0.51), walking speed (r=-0.62), and the vertical (r= 0.55) and anteroposterior (r= 0.54) postural sway velocities. The peak moment and work values of AINs and APFs; KFLs and KEXs; and HABs, HFLs, and HEXs showed a significantly positive correlation with the walking speed (α⩽ 0.05). CONCLUSION: The strength of HFLs, HEXs and HABs, as the important contributors to the walking performance, underwent attenuation as the age increased, consequently resulting in impairments of stepping profiles of elderly females. Elderly females are needed to be trained to reach the optimum levels of lower limb muscular strength to overcome premature incapacitation and have control over their independence in daily activities.

The impact of hippocampal segmentation methods on correlations with clinical data.

In vivo measurement of hippocampal volume with magnetic resonance imaging (MRI) has become an important element in neuroimaging research. However, hippocampal volumetric findings and their relationship with cardiovascular risk factors and memory performance are still controversial and inconsistent for non-demented adults. To compare total and regional hippocampal volumes from manual tracing and automated Freesurfer segmentation methods and their relationship with mid-life clinical data and late-life verbal episodic memory performance in older women. This study used structural MRI datasets from 161 women who were scanned in 2012 and underwent neuropsychological assessments. Of these participants, 135 women had completed baseline measures of cardiovascular risk factors in 1992. Our results showed a significant correlation between manual tracing and automated Freesurfer output segmentations of total (r = 0.71), anterior (r = 0.65), and posterior (r = 0.38) hippocampal volumes. Mid-life Framingham Cardiovascular Risk Profile score is not associated with late-life hippocampal volumes, adjusted for intracranial volume, age, education, and apolipoprotein E gene ε4 status. Anterior hippocampal volume segmented either with manual tracing or automated Freesurfer software is sensitive to changes in mid-life high-density lipoprotein (HDL) cholesterol level, while posterior hippocampal volume is linked with verbal episodic memory performance in elderly women. These findings support the use of Freesurfer automated segmentation measures for large datasets as being highly correlated with the manual tracing method. In addition, our results suggest intervention strategies that target mid-life HDL cholesterol level in women.

Whole Body Vibration Training on Muscle Strength and Brain-Derived Neurotrophic Factor Levels in Elderly Woman With Knee Osteoarthritis: A Randomized Clinical Trial Study.

Background: Osteoarthritis of the knee (kOA) is a chronic, progressive, degenerative health condition that contributes to the imbalance between the synthesis and destruction of articular cartilage. Recently, whole body vibration (WBV) training has been recommended as an effective alternative for strength training in elderly people, and various physiological effects are obtained in response to exercise performed on a vibratory platform, such as an increase in muscle activation and improved muscle performance. However, the effects of WBV particularly on the strength of the quadriceps muscle and neuronal plasticity are unknown.Objective: The aim of this study was to evaluate the effects of adding WBV to squat training on the isometric quadriceps muscle strength (IQMS) and the plasma levels of brain-derived neurotrophic factor (BDNF) in elderly woman with kOA.Methods: Fifteen elderly women ≥65 years of age with kOA were randomized into two interventions: (1) the vibration group (VG), in which participants performed squat exercise training in association with WBV or (2) the exercise group (EG), in which participants performed squat exercise training without vibration, for 12 weeks 3×/week.Results: Compared to the EG group, the VG group demonstrated a significantly greater delta (Δ) in IQMS values (IC95% 0.43–7.06; p ≤ 0.05) and in Δ BDNF plasma levels (IC95% −32.51 to 4.217; p ≤ 0.05) after the intervention period. There was an association between increase of Δ BDNF plasma levels and increase of Δ IQMS (β = 0.57; R2 = 0.32; p = 0.03).Conclusion: The addition of WBV to squat exercise training improves lower limb muscle performance in elderly women with kOA. These findings suggest that the improvement in muscle performance is related to neuromuscular adaptations induced by WBV.Clinical Trial Registration: www.ClinicalTrials.gov, identifier NCT03918291.

Functional resistance training can increase strength, knee torque ratio, and functional performance in elderly women.

Functional resistance training can increase strength, knee torque ratio, and functional performance in elderly women. The aim of the present study was to understand the effects of closed kinetic chain exercises with constant load on muscular strength, the knee torque conventional ratio (hamstring:quadriceps – H:Q), and functional capacity in the elderly. Nine untrained healthy elderly women participated in experimental resistance training. Ten-repetition maximum (10RM) for the deadlift, isokinetic maximum voluntary concentric contraction, and functional capacity were assessed before and after the 7-week resistance-training program. Magnitude based inference analysis was used to examine the differences in muscle strength and functional performance. Therefore, the smallest worthwhile change was calculated and 90% confidence intervals were also determined to characterize muscle strength and functional performance. The analysis demonstrated an increase in the deadlift and knee flexor torque (60o/sec) after the experimental intervention. Furthermore, stair ascent, knee extensor torque (120o/sec), knee flexor torque (120o/sec), and knee ratio (60o/sec) also presented a positive effect in the same training period. Conversely, knee extensor torque (60o/sec), and knee ratio (120o/sec) did not show conclusive responses. In conclusion, resistance training with functional closed kinetic chain exercises and constant volume load (i.e., 65% of 1-repetition maximum) can increase deadlift 10RM, isokinetic concentric torque, the conventional H:Q ratio, and stair ascent performance in elderly women.

Education as a Protective Factor Moderating the Effect of Depression on Memory Impairment in Elderly Women.

ObjectiveThe cognitive reserve theory explicates individual differences observed in the clinical manifestation of dementia despite similar brain pathology. Education, a popular proxy of the cognitive reserve, has been shown to have protective effects delaying the onset of clinical symptoms including memory. This study was conducted to test whether education can moderate the negative effect of depressive mood on memory performance in elderly women residing in the community.Methods29 elderly “unschooled” female (less than 6 years of formal education) and 49 “schooled” female (6 or more years) people were compared with regard to association between depressive mood and verbal memory functioning, which were measured by the Geriatric Depression Scale and the Elderly Verbal Learning Test, respectively.ResultsThe results showed that completing or receiving more than primary school education significantly reduced the negative association between depressive mood and memory performance. Participants who did not complete primary schooling showed a decline in memory test scores depending on the level of depressive mood; whereas participants who have completed or received more than primary education displayed relatively stable memory function despite varying level of depressive mood.ConclusionOur findings imply that education in early life may have protective effects against memory impairment related to elderly depression.

The Effect Of Resistance Training On Strength, Balance, And Coordination In Elderly Women

PURPOSE: Analyze the effect of 12 weeks of resistance training on strength, coordination, and balance performance in elderly women. METHODS: The effect of resistance training on strength, coordination, and balance performance was assessed in a total of 39 postmenopausal elderly women (age 71 ± 9 yrs) who were selected to participate in a protocol of 12 weeks of resistance training. The sample was separated into two groups, the intervention group (IG) with 29 women and the control group (CG) with 10 women. The resistance training protocol was applied three times a week engaging muscle groups between superior and inferior muscles. The exercises performed to superior muscles were the Pulley, Peck-Deck, Triceps Pulley, Hammer and Side Lateral Raise and the exercises to the inferior muscles were the Abductor, Adductor, Extension Chair, Flexor Bench, and Leg press 90°. Flexibility was tested using a Well’s Bench where the participant performed 3 attempts and the best score was recorded. The dynamic balance was analyzed using a circuit that was performed before the intervention beginning and at the end of 12 weeks. Following the prescriptions proposed by Rikli & Jones, the coordination test was performed using a complex task mixed with a circuit. RESULTS: The strength in superior limps statistically improved between CG and IG (11.40 ± 2,87 vs 19.50 ± 1,52) with similar results with the inferior limps strength (14,90 ± 3,10 vs 26,56 ± 3,17, p=0,001). Regarding dynamic balance, the IG presents a decrease in the time to complete to task compared to the CG (14,62 s ± 1,83 s vs 12,71 s ± 0,62 s, p < 0.05). There are no differences in the coordination between GC and IG. CONCLUSION: The main conclusion of this manuscript brings a new paradigm to the training methods used in elderly populations. The benefits related to the strength development using resistance training are in accordance with the present literature, however, in opposition to the present literature, we found that resistance training is effective in developing dynamic balance. Dynamic balance is fundamental in avoiding falls, which are one of the most common injuries in the elderly population. Therefore, it is fundamental that elderly people work to develop health and wellness by incorporating resistance training as a strategy to develop strength and balance.

Effects of once-weekly shallow water aerobic exercise on functional performance in elderly women

The purpose of this study was to examine the effects of 24-week shallow-water aerobic exercise on functional performance in postmenopausal women. Thirty-seven women aged 60+ (mean age 67.2 ± 4.8 years) were self-selected to a water exercise group (n = 21) or to a comparison group (n = 16). The training consisted of a 24-week (60 min.day−1, 1 d.wk−1) supervised and guided exercise programme that included aerobic and strength training using an aquatic noodle in shallow water (1.2 m). Outcome measures were 30-s chair stand and 30-s arm curl tests, assessed at baseline and 24 weeks. Significant differences between groups were analyzed using Fisher’s exact test. At 24 weeks there was a significantly (p < 0.05) greater improvement in measure of upper-body strength in the water exercise group. Arm curling improved by 15.8 versus 14.3% in the water exercise and comparison groups, respectively.

Effect of Brain Training on Cognitive Performance in Elderly Women Diagnosed with Mild Cognitive Impairment

Estrogen receptor beta polymorphisms and cognitive performance in women: associations and modifications by genetic and environmental influences.

Genetic and environmental risk factors contribute to the pathogenesis of Alzheimer's dementia. Besides known genetic risk factors like the apolipoprotein (APO) Eε4 allele, single nuclear polymorphisms (SNPs) of the estrogen receptors (ESRs) are candidate genetic risk factors, while air pollution represents an environmental risk factor for dementia. Effects of these risk factors and their interaction were investigated in the SALIA cohort of 834 non-demented elderly women. Cognitive function was assessed by the CERAD-plus test battery. Air pollution was estimated by land use regression (LUR) models. Genotyping was carried out for nine ESR1 and ESR2 SNPs and two ApoE SNPs. Carriers of minor ESR2 alleles showed significantly reduced cognitive performance in the CERAD total score with most pronounced deficits in semantic memory (rs1256062, rs10144225, and rs2274705) and executive function (rs1256062). The minor allele effects of ESR2 were stronger in carriers of APOEε4 for the cognitive domain 'executive function' (p value of interaction 0.023 for rs1256062). The investigated ESR1 SNPs were not associated with cognition. Furthermore, we found a significant gene-environment interaction between the ESR2 SNP rs1256062 and air pollution on cognition. Carriers of two major alleles of rs1256062 were more susceptible for an air pollution-induced decrease in performance of 'figure copying' than carriers of minor alleles (p value of interaction, e.g., 0.031 for PM2.5). In conclusion, ESR2 but not ESR1 minor alleles were associated with lower cognitive performance in elderly women with an indication of a gene-gene interaction with APOEε4. We also found indications for gene-environment interactions of ESR2 with traffic-related air pollution exposure on cognitive performance.

The impact of caffeine use across the lifespan on cognitive performance in elderly women

Habitual caffeine consumption has often been associated with decreasing age-related cognitive decline. However, whether habitual caffeine use preferentially spares different cognitive processes is unclear. Furthermore, whether basing habitual caffeine consumption patterns on current consumption or on a lifetime measure better represents an individual's use remains unclear. In the present study, we collected information from women, aged 56–83, about their current caffeine consumption patterns and history of use, including age they began consuming caffeine. Regression models assessed the relationship between caffeine consumption and performance on batteries designed to probe speed of processing, inhibition, memory, and executive function. While we found no direct associations between caffeine exposure and cognitive performance, we found that caffeine consumption and participant BMI interacted for inhibitory function and speed of processing performance. We discuss possible protective effects of long term caffeine use as well as the possibility of dose dependent effects.

Low level laser therapy associated with a strength training program on muscle performance in elderly women: a randomized double blind control study.

The aging process leads to a gradual loss of muscle mass and muscle performance, leading to a higher functional dependence. Within this context, many studies have demonstrated the benefits of a combination of physical exercise and low level laser therapy (LLLT) as an intervention that enhances muscle performance in young people and athletes. The aim of this study was to evaluate the effects of combination of LLLT and strength training on muscle performance in elderly women. For this, a hundred elderly women were screened, and 48 met all inclusion criteria to participate in this double-blind placebo-controlled trial. Volunteers were divided in three groups: control (CG = 15), strength training associated with placebo LLLT (TG = 17), and strength training associated with active LLLT (808nm, 100mW, 7J) (TLG = 16). The strength training consisted of knee flexion-extension performed with 80% of 1-repetition maximum (1-RM) during 8weeks. Several outcomes related to muscle performance were analyzed through the 6-min walk test (6-MWT), isokinetic dynamometry, surface electromyography (SEMG), lactate concentration, and 1-RM. The results revealed that a higher work (p = 0.0162), peak torque (p = 0.0309), and power (p = 0.0223) were observed in TLG compared to CG. Furthermore, both trained groups increased the 1-RM load (TG vs CG: p = 0.0067 and TLG vs CG: p < 0.0001) and decreased the lactate concentration in the third minute after isokinetic protocol (CG vs TLG: p = 0.0289 and CG vs TG: p = 0.0085). No difference in 6-MWT and in fatigue levels were observed among the groups. The present findings suggested that LLLT in combination with strength training was able to improve muscle performance in elderly people.

The effects of strength training on cognitive performance in elderly women.

Aging is a degenerative process marked by recognized functional, physiological, and metabolic impairments, such as dynapenia and diminished cognitive capacity. Therefore, the search for innovative strategies to prevent/delay these physiological and cognitive disorders is essential to guarantee the independence and life quality of an elderly population. The aim of this work is to verify the effect of a 12-week resistance exercise program on the general physical aptitude and cognitive capacities of elderly and sedentary women. Twenty-nine women (65.87±5.69 years) were divided into two groups. The control group was composed of eight elderly women who met the same inclusion criteria of the study and the strength training group was composed of 29 elderly women who were subjected to a resistance exercise program defined by 12 upper and lower limb exercises combined in 3×10 repetitions with 1-minute interval between repetitions and two resting minutes between exercises (three times/week). Weight loads were fixed between 60% and 75% of the apparent 1 repetition maximum, which was estimated by the test of 10 maximum repetitions. The direct curl was performed for upper body strength evaluation with 2.3 kg dumbbells for 30 seconds, whereas the chair test was used for lower body evaluation (total sit–stand movements in 30 seconds). The cognitive capacities of subjects were evaluated by “The Montreal Cognitive Assessment” questionnaire. After 12 weeks, the elderly group showed significant increases in the average upper body strength (58%), lower body strength (68%), and cognitive capacity (19%). The present study demonstrated that regular resistance exercises could provide significant gains on the upper and lower body strength concomitant to positive improvements on cognitive capacities of elderly women, bringing enhanced life quality.

Aerobic training modulates T cell activation in elderly women with knee osteoarthritis.

Osteoarthritis of the knee (kOA) is a disease that mainly affects the elderly and can lead to major physical and functional limitations. However, the specific effects of walking, particularly on the immune system, are unknown. Therefore, this study aimed to analyze the effect of 12 weeks of walking (3×/week) on the leukocyte profile and quality of life (QL) of elderly women with kOA. Sixteen women (age: 67±4 years, body mass index: 28.07±4.16 kg/m2) participated in a walking program. The variables were assessed before and after 12 weeks of training with a progressively longer duration (30–55 min) and higher intensity (72–82% of HRmax determined using a graded incremental treadmill test). The QL was assessed using the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36), and blood samples were collected for analysis with a cell counter and the San Fac flow cytometer. Walking training resulted in a 47% enhancement of the self-reported QL (P<0.05) and a 21% increase in the VO2max (P<0.0001) in elderly women with kOA. Furthermore, there was a reduction in CD4+ cells (pre=46.59±7%, post=44.58±9%, P=0.0189) and a higher fluorescence intensity for CD18+CD4+ (pre=45.30±10, post=64.27±33, P=0.0256) and CD18+CD8+ (pre=64.2±27, post=85.02±35, P=0.0130). In conclusion, the walking program stimulated leukocyte production, which may be related to the immunomodulatory effect of exercise. Walking also led to improvements in the QL and physical performance in elderly women with kOA.
