Research of Global Tilt and Functional Independence: Insights into Spinal Health of Older Women.

Spinal alignment intricately influences functional independence, particularly in older women with osteopenia experiencing mild neck and back pain. This study elucidates the interplay between spinal alignment, bone mineral density (BMD), and muscle strength in elderly women presenting with mild neck and back pain. Focusing on a cohort of 189 older women, we examined the associations among global tilt (GT), coronal and sagittal alignment, BMD, grip strength, and functional independence as gauged by the Barthel index. Our findings indicate significant associations between functional capacity and grip strength, bone density, GT, and pelvic tilt (PT). Elderly women with a Barthel Index above 80 demonstrated higher grip strength and better bone quality, reflected by less negative average T scores. These individuals also exhibited lower values of GT and PT, suggesting a better sagittal alignment compared to those with a Barthel index of 80 or below. The results highlight that deviations in GT and PT are significantly associated with decreased functional independence. These insights emphasize the importance of maintaining optimal spinal alignment and muscle strength to support functional independence in elderly women. This study underscores the potential for targeted interventions that improve postural stability and manage pain effectively in this vulnerable population.

Programações linear e ondulatória do treinamento de força induzem a mesmos resultados na aptidão física em mulheres idosas

Abstract The aim of the present study was to analyze the effect of two different types of resistance training programming (linear and daily undulating) on submaximal strength and functional capacity in elderly women. Twenty-two participants (64 ± 3 years) were randomly assigned to 2 training groups: linear programming (LP; n=12) and daily undulating programming (DUP; n =10). Functional capacity and submaximal strength (10RM) were analyzed before and after 12 weeks of resistance training. The results demonstrated improvement on strength and functional capacity after the resistance training period (p ≤ 0.05), except for the Bench Press (p = 0.30), for both groups DUP and LP. The Effect Size was, respectively, high for DUP (timed up and go test = -2.07, and timed sit test= 4.69), and high for LP (horizontal leg press = 2.35). For all other results, the effect size was trivial or small. No statistical difference was observed between programming models. The LP and DUP trainnings have similar results in increasing submaximal muscle strength in elderly women inexperienced in RT after 12 weeks of intervention (p ≤ 0,05). However, DUP appears to be more effective in increasing functional capacity. In practice, the professional can use both the LP and the DUP to improve the level of fitness in the early stages of training in this population. However, when the goal of programming is to increase functional capacity, DUP can be prioritized.

The Correlation Of Body Mass Index With Grip Muscle Strength In Elderly Women

Elderly (elderly) is closely related to problems with the musculoskeletal system. With increasing age, the elderly experience an aging process that will decrease the production of synovial fluid in the joints, decrease muscle tone and decrease muscle strength. One of the decrease in muscle strength is a decrease in hand grip muscle strength. Hand grip muscle strength can be influenced by several factors, one of which is body mass index (BMI). This study was conducted in May 2021 with the aim of knowing the relationship between body mass index and hand grip muscle strength in elderly women aged 60-67 years in Kemoning Village, Klungkung Regency, Bali. The research design used was cross sectional and obtained a sample of 12 people. Hand grip muscle strength was measured using the Hand Grip Dynamometer, while body mass index (BMI) was obtained from the calculation of body weight (kg) height (m²). The results of the study used the Pearson Product Moment correlation test with the value of Sig. (2-tailed) 0.000 and correlation closeness 0.887. This shows that there is a very strong significant correlation between BMI and hand grip muscle strength in elderly women aged 60-67 years. The hand grip muscle strength of the elderly with the thin category is smaller than the normal category.

Vitamin D Supplementation Associated With 12-Weeks Multimodal Training in Low Bone Mineral Density Older Women: A Randomized Double-Blind Placebo-Controlled Trial

To evaluate the influence of vitamin D supplementation associated with a multimodal exercise program on postural balance and muscle strength in elderly women with low bone mineral density and hypovitaminosis D.

Effect of resistance exercises applying maximum expiration on the respiratory muscle strength of elderly women.

Respiratory-muscle weakness is an important clinical problem. The respiratory system's health is a decisive factor in the physical and social life of the elderly. Changes in respiratory muscular strength and function activate the torso's adjustment ability, which affects daily activities. This study aimed to investigate the effects of resistance exercises combined with breathing exercises on the respiratory-muscle strength of elderly women. This study included 26 elderly woman, who were randomly divided into two sub-groups of 13 participants each. The experimental group performed breathing exercises and dynamic upper- and lower-extremity exercises, and the control group practiced only dynamic upper- and lower-extremity exercises. The maximum expiratory pressure (MEP) and maximum inspiratory pressure (MIP) were measured both before and at the end of the six-week study. In both groups, both the post-test MIPs and MEPs were significantly higher than the pre-intervention ones (p< 0.05). For MIPs, the between-group difference was not statistically significant, either before the intervention or post-test (p> 0.05). For MEPs, the between-group difference was statistically significant at post-intervention points (p< 0.05). The results showed that resistance exercises applying maximum expiration improved the respiratory-muscle strength of elderly women. These findings indicate that resistance exercises applying maximum expiration as described here in should be considered in patients who require breathing therapy, because the combination seems to significantly increase the strength of the respiratory muscles.

Effect of exercise therapy combined with branched-chain amino acid supplementation on muscle strength in elderly women after total hip arthroplasty: a randomized controlled trial.

Many patients develop a prolonged decrease of muscle strength after total hip arthroplasty (THA) despite their reconstructed hip joint. Physical exercise combined with branched-chain amino acid (BCAA) supplementation has been reported to improve muscle strength in elderly persons with sarcopenia. However, the effect of BCAA supplementation in patients after THA is unknown. This study examined the effects of BCAA supplementation combined with exercise therapy on the improvement of physical function in elderly patients after THA. The subjects were 31 elderly women who underwent THA. The participants were randomly assigned to two groups: BCAA (n=18) and control (n=13). The combined therapy was carried out for one month after THA. For the exercise intervention, a 3-set physical exercise program was conducted. For the nutritional intervention, the participants consumed 3.4 g of BCAA supplement or 1.2 g of starch immediately after the exercise intervention. BCAA supplementation combined with muscle strengthening exercises had a significant effect on knee extension strength of the contralateral side and on upper arm cross-sectional area. The improvement ratio of knee extension strength before and after intervention on the operated side was also significantly higher in the BCAA group. BCAA supplementation is effective for patients to improve the strength of some muscles when combined with physical exercises, but hip abductor muscle strength of the operated leg did not improve. A future study is needed to determine the efficacy of this combined therapy for hip abductor muscle strength.

The Effect of Lower Limb Resistance Exercise with Elastic Band on Balance, Walking Speed, and Muscle Strength in Elderly Women

Introduction: The aim of this study was to investigate the effect of an 8-week resistance exercise program on balance, walking speed, and muscle strength in elderly women.&#x0D; &#x0D; Methods: This randomized controlled trial was performed on 50 elderly women aged 60-66 years who were assigned to two groups of experimental and control. The Time Up and Go test, was used to measure dynamic balance, Romberg's test was used to measure static balance, and the 10 Meter Walk Test was used to measure walking speed, and the 30 Second Chair Stand test was used to measure muscle strength. Paired t-test and independent t-test was used for comparing balance time before and after the exercise program.&#x0D; &#x0D; Results: The mean duration of static balance increased in the experimental group from 21.64 ± 10.98 before exercise to 28.20 ± 13.47 after exercise (p &lt; 0.001). The mean duration of Up and Go Time decreased from 12.88 ± 1.45 seconds before exercise to 10.80 ± 1.80 seconds after exercise (p &lt; 0.001). Ten-meter walking time in the experimental group decreased from 1.15 ± 0.1 seconds before exercise to 1.00 ± 0.11 seconds after exercise (p &lt; 0.001) and muscle strength in the experimental group increased from 7.8 ± 1 before exercise to 9.56 ± 1.71 after exercise (p &lt; 0.001).&#x0D; &#x0D; Conclusion: Lower limb resistance exercises with elastic band improve static and dynamic balance and also walking speed, which possibly improve muscle strength. It is recommended that these exercises be considered in developing the elderly women's health care programs due to their accessibility, affordability, and reliability.

Reliability of a Test for Assessment of Isometric Trunk Muscle Strength in Elderly Women

Objective The aim of this study was to analyze the reproducibility of a protocol using the maximal isometric strength test of the trunk in elderly women aged above 60 years, without low back pain. Methods Twenty-one physically inactive elderly women, who had not engaged in any activity or exercise program in the past three months, participated in the cross-sectional study that consisted of two days of evaluations for the maximal isometric strength of the extensor and flexor muscles of the trunk, with a 48 h interval between the sessions. A platform with fixed seating was used, which allowed the fixation of the hip and lower limbs, with a load cell connected to a linear encoder. To verify the reliability of the test, the interclass correlation coefficient, variation coefficient, minimum detectable difference (MDD), standard error of measurement, and Bland–Altman graphs were calculated. Results No statistical difference was observed between the first and second evaluation, which indicates that there was no learning effect. Interclass correlation coefficient values were classified as very high and high for extensor (0.98) and flexor (0.86) muscles, respectively, besides low variation (9% for both muscle groups) and acceptable values for minimum detectable difference (extensors = 51.1 N, flexors = 48.9 N). In addition, the Bland–Altman analysis revealed low bias and values within the limits of agreement. Conclusion It is concluded that the test of maximum isometric strength of the trunk in healthy and trained elderly people presents high reliability. These values proved to be reliable if performed in at least two evaluation sessions, which confirms the hypothesis of the authors by the consistency of the measurement test.

The effects of hydrogymnastics on functional autonomy in elderly women: a meta-analysis

Abstract Aim: To Verify the effects of hydrogymnastics on functional autonomy in elderly women. Method: In November 2018, a systematic review of the literature was performed in the databases MEDLINE, SciELO, LILACS, PEDro, Cochrane, Web of Science, SPORTDiscus, SCOPUS e CINAHL. Two independent researchers selected randomized clinical trials, which evaluated the effects of hydrogymnastics over healthy elderly women performance on functional tests performance on functional tests. From each study they selected the number of participants in both experimental and control groups (EG and CG), age, intervention protocol, mean and standard deviation before and after the intervention for the following variables: legs and biceps muscular strength, posterior muscle chain extensibility, and agility - all of which compose the functional autonomy on Rikli and Jones test. We analyzed the methodological quality and the risk of bias through the Jadad Scale and the Cochrane tool respectively. We performed the data analysis through the random effects model and the mean difference between CG and EG. The analysis of the publication bias was done with Egger Test. Results: We found a total of 887 studies in the aforementioned databases, and five randomized clinical trials were included in the present meta-analysis. In spite of the evidence level is very low, the hydrogymnastics promoted an increase in agility and leg muscle strength in elderly women.

The impact of sarcopenic obesity on inflammation, lean body mass, and muscle strength in elderly women.

ObjectiveThe objective of this study was to apply the newly standardized definition for sarcopenia from the Foundation for the National Institutes of Health (FNIH) and the current definition for obesity to 1) determine the prevalence of sarcopenic obesity (SO) in obese elderly women; 2) compare the muscle strength, lean body mass, and markers of inflammation between obese elderly women with SO and nonsarcopenic obesity (NSO), and 3) elucidate the relationship between appendicular lean mass adjusted for body mass index (aLM/BMI) with muscle strength, lean body mass, and obesity indices.MethodsA total of 64 elderly obese women (age: 68.35±6.04 years) underwent body composition analysis by dual-energy X-ray absorptiometry. Participants were classified into two groups according to the definition of SO and NSO. Blood samples were collected for total cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein, uric acid, urea, interleukin-6 (IL-6), glucose, and creatine kinase (CK) measurements.ResultsThe SO group presented a significantly greater BMI, fat (%), glucose, a marginal trend toward significance for uric acid, and IL-6 compared to the NSO group. In addition, the SO group displayed lower values for muscle strength and lean body mass. From a correlation standpoint, a higher aLM/BMI was positively associated with lean body mass and muscle strength and negatively associated with a lower BMI and percentage body fat.ConclusionThe definition criteria from FNIH and obesity permit the ability to illustrate the prevalence and identify SO in elderly women with low muscle mass, low muscle strength, and impaired markers of inflammation.

Effects of a therapeutic exercises program associated with pompage technique on pain, balance and strength in elderly women with knee osteoarthritis

Abstract Introduction: Knee Osteoarthritis (OA) affects mainly elderly, being characterized by arthralgia, stiffness and strength and balance deficits. Scientific evidence suggests beneficial effects of exercise therapy on these changes, but lacks detailed protocols. In addition, there were published studies on effects of therapeutic exercise associated with pompage that were not located. Objective: To investigate the effects of a therapeutic exercise program associated with pompage on pain, balance and muscle strength in elderly women with knee osteoarthritis. Methods: A randomized pilot clinical trial that included 22 women (60 - 80 years) diagnosed with knee OA, randomized and allocated by simple raffle into two groups: intervention and control. Intervention group (strengthening and balance exercises and knee pompage) performed two sessions per week for 12 weeks. The control group received educational lectures, they were evaluated before and after 12 weeks: arthralgia- subscale pain of the Western Ontario and McMaster Universities Osteoarthritis Index questionnaire (WOMAC); postural stability- postural balance protocol by Biodex Balance SD and muscle strength- concentric peak torque of the knee extensor by isokinetic dynamometer. The Independent Student t test was used for intergroup analysis. Results: The intervention group compared with the control showed better results for the outcomes pain, balance and muscle strength after 12 weeks. However, the difference was statistically significant (p &lt; 0.05) for levels of antero-posterior oscillation (DM -0.28, 95% CI -0.54 a -0.02; p = 0.035) and global oscillation (DM -0.36, 95% CI -0.68 a -0.04; p = 0.028). Conclusion: The intervention had a positive effect on postural balance in elderly women with knee osteoarthritis.

Effect of low-intensity resistance training with heat stress on the HSP72, anabolic hormones, muscle size, and strength in elderly women.

Several recent studies have reported that heat stress stimulates the activation of heat shock protein 72 (HSP72), leading to an increase in muscle synthesis. Some studies suggested that low-intensity resistance training combined with heat stress could improve muscle size and strength. This study aimed to identify the effect of low-intensity resistance training with heat stress over 12weeks on the HSP72, anabolic hormones, muscle size, and strength in elderly women. The subjects were physically healthy women of 65-75years, who were randomly assigned to one of three groups: a low-intensity resistance training with heating sheet group (HRT group, n=8), a moderate-intensity resistance training (RT group, n=6), and a heating sheet group (HEAT group, n=7). Computed tomography scans, 1-repetition maximum (1RM), and blood samples were taken pre- and post-training. The HSP72 did not vary significantly between the different groups and times. The IGF-1 and 1RM had significantly increased in all three groups after the training (respectively, p<0.05). Moreover, the cross-sectional area (CSA) of the quadriceps showed a significantly greater increase in the HRT group than in the HEAT group (p<0.05). We found that low-intensity training with heat stress stimulated the anabolic hormones of elderly women, improving their muscle strength and hypertrophy. We believe that low-intensity training with heat stress is an effective way to prevent muscle atrophy and to improve muscle strength in elderly women.

Changes in muscle strength in elderly women after proprioceptive neuromuscular facilitation based training

Introduction Proprioceptive neuromuscular facilitation (PNF) can be used to improve the quality of life of both healthy and diseased subjects, including the elderly, who suffer muscular weakness due to aging, leading to an impairment in functional capacity. Objective Verify the effectiveness of PNF as a tool for functional conditioning. Materials and methods We evaluated a total of ten elderly women aged 60–70 years, clinically healthy and physically active. They had the force of motion of hip flexion with knee extension analyzed by an analog dynamometer. They were then randomly and equally divided into experimental (EG) and control group (CG). The GC was instructed to continue with their normal activities while the GE held 15 training sessions in the lower limb (LL) based on the diagonal D1 and D2. Finally, a new collection wrench the two groups was performed and the data compared. Results There was a significant increase in the average strength of GE, on the order of 31% (p &lt; 0.01). The GC also had increased strength, but not significant (p &gt; 0.05). Discussion : The results confirm that the FNP through initial work of readjustment and proprioceptive neuromuscular activation, and after that, conditioning of the muscle fibers (mainly resistive) is capable of amplifying the force developed by the muscle. Conclusion The PNF was effective as training to gain muscle strength, should be better analyzed as a tool fitness, not to cause health risks, have low cost and easy application.

Effects of combined application of progressive resistance training and Russian electrical stimulation on quadriceps femoris muscle strength in elderly women with knee osteoarthritis.

[Purpose] The aim of this study was to investigate the effects of combined application of progressive resistance training and Russian electrical stimulation on quadriceps femoris muscle strength in elderly women with osteoarthritis of the knee. [Subjects] Thirty women over 65 years of age diagnosed with knee osteoarthritis participated in the present study. The subjects were randomly assigned to a control group (n=10), a progressive resistance training group (n=10), or a Russian electrical stimulation group (n=10). [Methods] Each group was treated 3 times weekly for 8 weeks, and each session lasted 45 minutes. Muscle strength was assessed by measuring the peak torque of the quadriceps femoris muscle. Outcome measurements were performed at baseline and at the fourth and eighth weeks of the treatment period. [Results] All groups showed significant intragroup differences in the quadriceps femoris muscle peak torque after the treatment intervention. There were significant intergroup differences between the Russian electrical stimulation group and the other groups. [Conclusion] The results of this study suggest that combined application of progressive resistance training and Russian electrical stimulation can be effective in strengthening the quadriceps femoris muscle in elderly women with knee osteoarthritis.

Proprioceptive neuromuscular facilitation and strength training to gain muscle strength in elderly women

Introduction: The world population is aging, and this leads to progressive physiological changes and increased incidence of acute and chronic degenerative diseases. In this sense, one of the main changes occurring during this period is sarcopenia, characterized by decreased skeletal muscle mass. Objective: To perform comparative analyze of results of proprioceptive neuromuscular facilitation (PNF) techniques and strength training to gain muscle strength of biceps and quadriceps and grip in the elderly. Method: This is a prospective randomized study with purposive sample of 17 elderly patients undergoing a program of strength training and evaluation with a dynamometer, before and after applying the treatment protocol. After evaluation, subjects were randomly divided into two groups: PNF and Bodybuilding. Results: The group trained with PNF had more significant gain in muscle strength, biceps (p=0.0392*) and quadriceps (p=0.0230*) did not show statistically significant relevance in the grip (p=0.1075). In the group trained with weights there was no statistically significant difference: biceps (p=0.5338), quadriceps femoris (p=0.0679) and palmar (p=0.3758). Comparing both techniques, however, there was no statistical difference: biceps (p=0.5739), quadriceps (p=0.8450) and palmar (p=0.2457). Conclusion: This study showed that the period of 12 weeks of intervention seems to be sufficient to achieve gains in muscle strength with PNF technique, but when comparing the two techniques it was not statistically significant.

Decreased functional capacity and muscle strength in elderly women with metabolic syndrome

PurposeTo compare the metabolic parameters, flexibility, muscle strength, functional capacity, and lower limb muscle power of elderly women with and without the metabolic syndrome (MetS).MethodsThis cross-sectional study included 28 older women divided into two groups: with the MetS (n = 14; 67.3 ± 5.5 years; 67.5 ± 16.7 kg; 1.45 ± 0.35 m; 28.0 ± 7.6 kg/m2), and without the MetS (n = 14; 68.7 ± 5.3 years; 58.2 ± 9.9 kg; 1.55 ± 0.10 m; 24.3 ± 3.8 kg/m2). Body composition was evaluated by dual-energy X-ray absorptiometry and dynamic muscle strength was assessed by one-maximum repetition (1RM) tests in leg press, bench press and biceps curl exercises. Six-minute walk test, Timed Up and Go (TUG); 30-second sitting-rising; arm curl using a 2-kg dumbbell, sit-and-reach (flexibility), and vertical jump tests were performed.ResultsThere was no difference between groups regarding age (P = 0.49), height (P = 0.46), body fat (%) (P = 0.19), systolic (P = 0.64), diastolic (P = 0.41) and mean blood pressure (P = 0.86), 30-second sitting-rising (P = 0.57), 30-s arm curl (P = 0.73), leg press 1RM (P = 0.51), bench press 1RM (P = 0.77), and biceps curl 1RM (P = 0.85). However, women without the MetS presented lower body mass (P = 0.001), body mass index (BMI) (P = 0.0001), waist circumference (P = 0.02), waist-to-height ratio (P = 0.02), fat body mass (kg) (P = 0.05), lean body mass (kg) (P = 0.02), blood glucose (P = 0.05), triglycerides (P = 0.03), Z-score for the MetS (P = 0.05), higher high-density lipoprotein-cholesterol (HDL-C) (P = 0.002), better performance on TUG (P = 0.01), flexibility (P = 0.03), six-minute walk test (P = 0.04), vertical jump (P = 0.05) and relative muscle strength for leg press (P = 0.03), bench press (P = 0.04) and biceps curl (P = 0.002) exercises as compared to women with the MetS.ConclusionElderly women with the MetS have higher metabolic risk profile and lower functional capacity, muscle strength, lower limb power and flexibility as compared to women without the MetS. The evaluation of functional capacity may help to determine the degree of physical decline in older persons with the MetS, while exercise interventions should be encouraged.

Fish-oil supplementation enhances the effects of strength training in elderly women

Muscle force and functional capacity generally decrease with aging in the older population, although this effect can be reversed, attenuated, or both through strength training. Fish oil (FO), which is rich in n-3 (omega-3) PUFAs, has been shown to play a role in the plasma membrane and cell function of muscles, which may enhance the benefits of training. The effect of strength training and FO supplementation on the neuromuscular system of the elderly has not been investigated. The objective was to investigate the chronic effect of FO supplementation and strength training on the neuromuscular system (muscle strength and functional capacity) of older women. Forty-five women (aged 64 ± 1.4 y) were randomly assigned to 3 groups. One group performed strength training only (ST group) for 90 d, whereas the others performed the same strength-training program and received FO supplementation (2 g/d) for 90 d (ST90 group) or for 150 d (ST150 group; supplemented 60 d before training). Muscle strength and functional capacity were assessed before and after the training period. No differences in the pretraining period were found between groups for any of the variables. The peak torque and rate of torque development for all muscles (knee flexor and extensor, plantar and dorsiflexor) increased from pre- to posttraining in all groups. However, the effect was greater in the ST90 and ST150 groups than in the ST group. The activation level and electromechanical delay of the muscles changed from pre- to posttraining only for the ST90 and ST150 groups. Chair-rising performance in the FO groups was higher than in the ST group. Strength training increased muscle strength in elderly women. The inclusion of FO supplementation caused greater improvements in muscle strength and functional capacity.
