Is Resistance Training an Option to Improve Functionality and Muscle Strength in Middle-Aged People with Multiple Sclerosis? A Systematic Review and Meta-Analysis.

Background: Currently, it is essential to adopt physical therapy strategies, such as resistance training, to enhance muscle strength and gait in middle-aged individuals (ages 45-65) suffering from Multiple Sclerosis. This is crucial in combating the typical symptoms of neurodegenerative diseases associated with functional loss. The objective of this study is to determine the effects of resistance training interventions on walking and muscle strength in middle-aged people with Multiple Sclerosis. Methods: A systematic review with meta-analysis was conducted by searching specific keywords in the PubMed, Scopus, Cochrane, and Web of Science databases. For inclusion, studies had to incorporate resistance training as a primary or significant component of the overall intervention for middle-aged patients with MS. Out of the 3675 articles identified, 12 randomized clinical trials met the criteria for inclusion in the review, with resistance training being a consistent feature in all of them. Results: Muscle strength and gait were evaluated as the main variables, with fatigue and the quality of life as secondary variables. This review reveals that resistance training significantly improves muscle strength. Resistance training achieves modest and non-significant improvements in gait. Notably, studies combining resistance training with motor control exercises achieve results of greater clinical significance in terms of gait. However, resistance training yields variable positive effects on perceived fatigue and the quality of life. Conclusion: Resistance training is useful for improving muscle strength; however, walking needs to be combined with motor control training.

Moderate-intensity continuous training and high-intensity interval training modulate the composition of the oral microbiota of elderly adults: Randomized controlled trial.

OBJECTIVE: We investigates the effects of 16-week high-intensity interval training and moderate-intensity continuous training on the composition of the oral microbiota. To the best of our knowledge, at the time of writing this paper no other scholars had described the oral metagenomic changes associated with prescribed exercise in older adults. METHODS: Forty-three participants aged 60-74 years were randomized 1:1:1 to a control group, high-intensity interval training or moderate-intensity continuous training twice weekly for 16 weeks. Saliva samples were sequenced at baseline, week 8 and week 16 of intervention. RESULTS: High-intensity interval training produced significant differences over time in Richness and a clear trend to decreased Simpson and Shannon diversity indices. In contrast, Simpson and Shannon indices showed an upward trend over time with moderate-intensity continuous training, which also decreased Firmicutes and increased Bacteroidetes levels. Significant differences in the abundance of pathogenic species were also observed after the participants completed the exercise interventions of either type. CONCLUSIONS: Both types of exercise promoted subtle changes in the oral microbiota, confirming the modulatory effect of high-intensity interval training and moderate-intensity continuous training on the oral microbiome.

Falls and Sleep Disorders in Spanish Alzheimer's Disease in Nursing Homes: An Observational Study.

OBJECTIVE: The main objective of this study was to establish a relationship between the number of falls and sleep problems experienced by patients with Alzheimer's disease. MATERIALS AND METHODS: This was a cross-sectional study. A total of 114 Spanish aged people with Alzheimer's disease institutionalized in nursing homes and 80 independent Spanish aged people without neurodegenerative diseases living at home were enrolled in this study and completed in-person interviews and digital questionnaires. RESULTS: The mean age was 78.98 ± 8.59 years. Sleep disorders were related to continuous stress (p = 0.001; OR = 4.729) and a high frequency of falls (p = 0.001; OR = 2.145), while predictor variables associated with falls in patients with Alzheimer's disease were continuous medical visits (ß = 0.319, p < 0.001), family history of dementia (ß = 0.212; p = 0.014), and sleep disorders (ß = 0.235; p = 0.007). Second, the analysis showed that moderate physical activity (p = 0.001; OR = 0.147), continuous medical visits (p < 0.001; OR = 0.621), and high level of study (p = 0.011; OR = 0.334) were protective factors against Alzheimer's, while older age (p = 0.035; OR = 1.087), type II Diabetes Mellitus (p = 0.042; OR = 3.973), number of falls (p = 0.021; OR = 1.409), and daily drug intake (p = 0.001; OR = 1.437) were risk factors for Alzheimer's. CONCLUSIONS: Sleep disturbances are related to stress and falls in a sample of 114 Spanish AD aged people institutionalized in nursing homes, and the falls they experience are related to ongoing medical visits, a history of dementia, and sleep disturbances. Therefore, a bidirectional relationship was established between falls and sleep disorders in these patients. Moreover, this study showed that a greater frequency of falls and high daily drug intake could constitute novel risk factors for Alzheimer's disease, in addition to already known factors, such as age and type II Diabetes Mellitus, while being physically active and a high level of studies are protective factors against Alzheimer's disease.

Influence of Nutritional Status and Physical Fitness on Cognitive Domains among Older Adults: A Cross-Sectional Study.

BACKGROUND: The health issues presented by the aging population can result in reduced muscle mass, poorer physical function, and cognitive impairment. The goal of this study was to determine how nutritional status and physical fitness relate to cognitive impairment in older adults. METHODS: A cross-sectional descriptive and analytical study involving 100 participants was carried out to analyze the impact of nutritional status and physical fitness on cognitive impairment. Nutritional status was assessed with the Eating Assessment Tool (EAT-10) and The Mini Nutritional Assessment-Short Form (MNA-SF); physical fitness via the implementation of manual grip evaluation, the 4-m walking test (4-MWT), and the Timed Up and Go (TUG) test; and cognitive impairment evaluation was conducted using the Mini-Mental State Examination (MMSE), the Boston Naming Test (BNT) and the Controlled Oral Word Association Test (COWAT). RESULTS: Data analysis revealed that higher malnutrition status was associated with fewer correct responses in the COWAT (R2 = 0.421), while a correlation between higher MMSE and BNT scores, faster completion times for the 4-m walking and TUG tests, and an increase in handgrip strength load was also observed. CONCLUSION: The analysis of the data revealed that those individuals with superior nutritional status and greater levels of physical fitness outperformed others on the cognitive evaluation.

Differences in Various Strength Manifestations Between the Flat and Retracted Bench Press Variants: Are They Affected by Subjects' Experience or Strength Levels?

ABSTRACT: Piepoli, A, Miras-Moreno, S, Janicijevic, D, Martínez-Amat, A, and García-Ramos, A. Differences in various strength manifestations between the flat and retracted bench press variants: are they affected by subjects' experience or strength levels? J Strength Cond Res 37(12): 2339-2345, 2023. The objective of this study was to explore the effect of retracting the scapulae during the free-weight bench press (BP) exercise on various strength manifestations and perceptual variables. Twenty-eight recreationally trained male lifters (BP 1-repetition maximum [1RM] = 96.1 ± 20.8 kg) randomly performed in 2 different sessions: the flat BP (scapulae free to move during the movement) and retracted BP (shoulders retracted during the movement). Three strength manifestations were evaluated: (a) explosive strength -mean velocity (MV) achieved against 3 submaximal loads (40, 60, and 80%1RM); (b) maximal strength -1RM; and (c) endurance strength -number of repetitions completed to failure against the 70%1RM. Discomfort and ratings of perceived exertion (RPE) values were also recorded immediately after completing each test. The upward displacement of the barbell was lower for the retracted BP compared with the flat BP at the 3 submaximal loads ( p ≤ 0.024), but no significant differences between the BP variants were observed for the MV at submaximal loads ( p ≥ 0.473), 1RM ( p = 0.147), number of repetitions completed to failure ( p = 0.447), RPE at submaximal loads ( p ≥ 0.363), or discomfort during any test ( p ≥ 0.611). Subjects always demonstrated a greater strength performance with the BP variant most used in their training programs, but the differences between the flat and retracted BP were not affected by subjects' maximal strength values ( p ≥ 0.162). These results suggest that retracting the scapulae during the BP exercise presents minor effects on different strength manifestations and perceptual measures of effort and discomfort.

Does participation in therapeutic exercise programs after finishing oncology treatment still ensure an adequate health status for long-term breast cancer survivors? A ≥ 5 years follow-up study.

PURPOSE: The aims of this study were to evaluate whether the effects of two therapeutic exercise programs are sustained over time (≥ 5 years) in long-term breast cancer survivors (LTBCS). Second, to determine the influence of the current level of physical activity (PA) performed on cancer-related fatigue (CRF) that these patients may present ≥5 years later. METHODS: A prospective observational study was conducted with a cohort of 80 LTBCS in Granada during 2018. Firstly, considering their participation in one of the programs, they were allocated into two groups: usual care and therapeutic exercise program, to assess CRF, pain and pressure pain sensitivity, muscle strength, functional capacity, and quality of life. Secondly, they were also classified into 3 groups according to current level of weekly PA performed: ≤ 3, 3.1-7.4, and ≥ 7.5 (MET-hour/week) respectively, to assess its impact over CRF. RESULTS: Although the positive effects of the programs are not sustained over time, a trend toward significance can be observed for a greater reduction in overall CRF levels, lower intensity of pain in the affected arm and cervical region, and greater functional capacity and quality of life in the group that underwent therapeutic exercise. Additionally, 66.25% of LTBCS are inactive ≥ 5 years after completion of the program and furthermore, such inactivity is accompanied by higher CRF levels (P .013 to .046). CONCLUSION: The positive effects of therapeutic exercise programs are not maintained over time for LTBCS. Additionally, more than half of these women (66.25%) are inactive ≥ 5 years after completion of the program, this inactivity being accompanied by higher levels of CRF.

Impact of Qigong exercises on the severity of the menopausal symptoms and health-related quality of life: A randomised controlled trial.

The aim of the present study was to analyze the effects of a Qigong exercise programme on the severity of the menopausal symptoms and health-related quality of life (HRQoL) of community-dwelling postmenopausal women. This was done by means of a randomised clinical trial with a sample of 125 women who were assigned to either a control (n = 62) or an experimental group (n = 63). The severity of their menopause-related symptoms and HRQoL were assessed through the Menopause Rating Scale (MRS) and the 36-item Short-Form Health Survey (SF-36) respectively, before and after the intervention period. The main findings of our study reveal significant improvement in the severity of menopausal symptoms at the somatic, psychological, and urogenital levels, as well as in the total score of the MRS. Additionally, participants assigned to the Qigong group experienced improvement in the general health, physical functioning, role-physical, bodily pain, vitality, and mental health domains of the 36-item Short-Form Health Survey, as well as in its physical component and mental component summaries. We can therefore conclude that, among Spanish postmenopausal women, a twelve-week Qigong exercise programme has beneficial effects on the severity of menopausal symptoms and HRQoL.HighlightsWe have studied the effects of Qigong on menopause-related quality of life.Qigong is a useful tool in the management of the severity of menopausal symptoms.A 12-week Qigong programme showed benefits on health-related quality of life.Trial registration: ClinicalTrials.gov identifier: NCT03989453.

Time course and predictors of persistent cancer-related fatigue in long-term breast cancer survivors: a prospective observational study.

PURPOSE: The present study investigated whether the level of cancer-related fatigue (CRF) after finishing oncology treatment was related to higher levels of persistent CRF and its relationship with both functional and psychological disturbances. Second, to identify potential predictors of persistent CRF. METHODS: Eighty BC survivors were classified into non-fatigued (≤ 3.9) or fatigued (≥ 4), according to their Piper Fatigue Scale total score after finishing oncology treatment. The time course of fatigue and the impact on its domains, pain, mood state, perceived physical fitness, the level of physical activity, and quality of life were assessed at ≥ 5 years. RESULTS: Women classified as fatigued after finishing oncology treatment had not only a higher prevalence of persistent CRF (41.2%) at the reassessment, but also greater levels of pain (P = .006 to .048) and mood disturbances (P = .007 to .015), and lower levels of physical fitness condition (P = .002 to .039) and quality of life (P < .001 to < .05) over time. Regression analyses revealed that "sadness/depression," "global health status," "physical activity level," and "type of treatment" were significant predictors of persistent CRF (r2 = .692). CONCLUSION: Higher levels of CRF implied greater levels of persistent CRF and a lower functional and psychological profile over time. 69.2% of of persistent CRF was explained.

High-intensity interval training among middle-aged and older adults for body composition and muscle strength: A systematic review.

Background: The aging of population is leading to the investigation of new options to achieve healthy aging. One of these options is high-intensity interval training (HIIT), although its effects on body composition and muscle strength are currently unclear. The objective of this systematic review is to examine the scientific publications on the effects of HIIT on the body composition and muscle strength of middle-aged and older adults. Methods: The search was carried out in the PubMed, Cochrane Plus, Web of Science, CINAHL and SciELO databases without limitation of publication dates. The literature search, data extraction and systematic review were performed following the PRISMA standards and the risk of bias of the selected studies was assessed using the Cochrane Collaboration Risk-of-Bias. Results: Initially 520 publications were identified, out of which a total of 8 articles were finally selected to be included in this systematic review. Improvements in body composition were seen in six of the selected items and an increase in muscle strength in seven of the eight. Regarding physical function, improvements were found in both gait speed and balance. Conclusions: This systematic review found that HIIT is effective in improving body composition and increasing muscle strength. However, when comparing HIIT to moderate-intensity continuous training, it is not clear that HIIT is more beneficial; a firm conclusion cannot be drawn due to the scarcity of published studies, their variety in methodology and the ambiguity of their results, so it is suggested to carry out more research in this area.

Qigong for mental health and sleep quality in postmenopausal women: A randomized controlled trial.

BACKGROUND: Menopause is one of the stages in a woman's life that affects her psychological health, the most frequent being anxiety and depression. In addition, another problem related to this stage is the lack of sleep that causes a decrease in the quality of sleep. The purpose of this randomized controlled trial was to analyze the effectiveness of a Qigong exercise program on sleep quality, anxiety, and depression in Spanish postmenopausal women. METHODS: A total of 125 women were randomly assigned to an experimental group (EG) (n = 63) that carried out a Qigong exercise program for 12 weeks, or a control group (CG) (n = 62), which did not perform any type of intervention. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) and anxiety and depression using the Hospital Anxiety and Depression Scale (HADS). RESULTS: Women who underwent an intervention program experienced significant improvements for all measured variables, except for the use of sleeping medication and daytime dysfunctions that did not show any significant effect with respect to the group and group × time interaction. CONCLUSIONS: After an intervention based on a BaDuanJin Qigong exercise program for 12 weeks, improvements were observed in sleep quality, sleep latency, sleep duration, sleep efficiency, sleep disturbances, the total score of the PSQI, anxiety and depression in postmenopausal Spanish women.

Associations between Muscle Strength, Physical Performance and Cognitive Impairment with Fear of Falling among Older Adults Aged ≥ 60 Years: A Cross-Sectional Study.

(1) Background: Fear of falling has become a significant health problem in older adults and is already considered as important as falling because of its long-term detrimental effects on older adults' physical and psychosocial functioning. The aim of this study was to analyze the associations between both upper and lower limb strength, gait parameters and cognitive impairment with fear of falling in older adults. (2) Methods: A cross-sectional study involving 115 older-adult participants was used to assess the impact of both upper (Handgrip dynamometer, TKK 5401 Grip-D, Takey, Tokyo, Japan) and lower limb strength (Chair stand test), gait parameters (OptoGait-System Bolzano, Bolzano, Italy) and cognitive impairment (COWAT word association test) with fear of falling in older adults (Falls Efficacy Scale-International FES-I). (3) Results: Multivariate linear regression analysis showed several independent associations with the fear of falling. A higher time to perform the Chair Stand test was associated with higher scores in FES-I (R2 = 0.231), while a lower score in both Semantic Fluency (S COWA) and Phonologic Fluency (P COWA) was associated with a decreased score in FES-I (R2 = 0.052 and 0.035). (4) Conclusions: Both higher step and stride length (OptoGait), lower body strength (Chair test) and both poorer semantic (S COWA) and phonologic (P COWA) fluency were all associated with fear of falling.

Acute Effects of High-Intensity Functional Training and Moderate-Intensity Continuous Training on Cognitive Functions in Young Adults.

BACKGROUND: The purpose of the present study was to compare the influence of an acute bout of high-intensity functional training (HIFT) with an acute bout of moderate-intensity continuous training (MICT) on measures of cognitive function. METHODS: Sixty-nine young adults (Mean ± SD: age = 21.01 ± 2.79 yrs; body mass = 69.65 ± 6.62 kg; height = 1.74 ± 0.05 m; Body Mass Index = 22.8 ± 1.41) gave informed consent and were randomly divided into three groups. The HIFT group, with 27 participants, performed a high-intensity (>85% Max. HR) circuit of functional exercises for 30 min. The MICT group, with 28 participants, performed moderate-intensity (70-80% Max. HR) continuous training on a cyclo-ergometer. The control group did not perform any activity. The Stroop Test, Word Recall and N-Back Test were completed to assess during the familiarization period, immediately before and immediately after the training's bouts. RESULTS: The repeated measures ANOVA did not show significant mean differences for any group. However, the T-Test for the paired samples demonstrated very significant differences in the Stroop Test, in terms of fastest response time (FRT; mean difference (MD) = -1.14, p < 0.01, d = 0.9), mean response time (MRT; MD = -2.16, p < 0.01, d = 0.66) and the number of correct answers (NCA; MD = 1.08, p < 0.05, d = 0.5) in the HIFT group and in the MICT group (FRT; MD = -1.79, p < 0.01, d = 0.9), (MRT; MD = -3.07, p < 0.01, d = 0.9) (NCA; MD = 1.54, p < 0.05, d = 0.5). CONCLUSIONS: There were no differences in the control group. HIFT and MICT may elicit specific influences on cognitive function, mainly in executive function and selective attention.

Factors Associated with the Level of Physical Activity in Middle-Aged Colombian People during Lockdown in Response to COVID-19: A Cross-Sectional Study.

(1) Background: Due to the pandemic caused by COVID-19, mandatory confinement was declared, which generated a decrease in the practice of physical activity (PA). Based on this problem, it was proposed to study the associations between PA in relation to depressive symptoms, quality of sleep, and the quality of life of middle-aged people who work in the university context during compulsory confinement as a result of COVID-19. (2) Methods: A total of 336 middle-aged people (48 ± 6.67) participated in this analytical cross-sectional study. The variable levels of PA, quality of sleep, symptoms of depression, and quality of life were measured with the International Physical Activity Questionary (IPAQ), the Pittsburgh Sleep Quality Index (PSQI), the Zung Self-Rating Depression Scale (ZSDS), and the SF-12v2 questionnaire, respectively. (3) Results: A logistic regression model was used to analyze the relationships between the level of PA and depressive symptoms (OR = 2.053), total sleep duration (OR = 0.495), sleep disturbances (OR = 2.414), quality of sleep (OR = 2.471), use of sleep medication (OR = 0.348), daytime dysfunction (OR = 1.809), general health (OR = 0.949), and physical functioning (OR = 0.987). (4) Conclusions: In middle-aged people, during compulsory confinement, being insufficiently active is a risk for depressive symptoms and disturbances in sleep quality.

Changes in satisfaction with female genital self-image and sexual function after a Qigong exercise intervention in Spanish postmenopausal women: a randomized-controlled trial.

OBJECTIVE: To analyze the effectiveness of a Qigong exercise program on satisfaction with female genital self-image and female sexual function in postmenopausal Spanish women. METHODS: A total of 49 women were randomly assigned to an experimental group (n = 22) that carried out training based on Qigong exercises for 12 weeks and a control group (n = 27) that did not carry out any type of intervention. Female genital self-image was measured through the Female Genital Self-Tmage Scale and female sexual function through the Female Sexual Function Tndex; both variables were measured before and just after the intervention. RESULTS: Results showed that women who participated in the Qigong exercise program showed significant improvements with respect to female genital self-image, as well as in the domains of desire, arousal, lubrication, satisfaction, and pain and the total score of the Female Sexual Function Index, but, on the contrary, were not found in the orgasm domain. CONCLUSIONS: Our results suggest that Qigong has the potential to improve female genital self-image and female sexual function among postmenopausal Spanish women.

The Effects of High-Intensity Functional Training on Cognition in Older Adults with Cognitive Impairment: A Systematic Review.

(1) Background: High-Intensity Functional Training (HIFT) is a new exercise modality that emphasizes multi-joint functional movements adaptable to any fitness level and promotes greater muscle recruitment. Previous studies have evaluated the positive effects of HIFT on mental and cognitive health but have not evaluated it in older people. This study aims to conduct a systematic review of randomized controlled trials assessing the effects of HIFT on general cognition in older adults with cognitive impairment. (2) Methods: Following the PRISMA 2020 guideline, articles that did a high-intensity functional physical exercise intervention on cognitive performance in older adults with mild to moderate cognitive impairment (MMSE > 10) or dementia, aged 55 years or older, published between 2011 and 2021 in five different electronic databases: PubMed, Web of Science, Scopus, CINAHL, and Cochrane plus were included. (3) Results: 7 articles were included, all having general cognition as their primary outcome. All assessed general cognition using the Mini-Mental State Examination, the ADAS-Cog, or both. All studies had at least one HIFT experimental group with a frequency of 2 sessions per week and a variable duration between protocols of 12, 13, 16, and 26 weeks. Two articles showed that a progressive HIFT program improves general cognition, four articles showed no significant changes within or between groups and one article concluded that a HIFT intervention does not slow cognitive decline. (4) Conclusions: Evidence exists of the benefits of HIFT on general cognition in older adults with cognitive impairment, assessed using the MMSE, the ADAS-cog, or both. Two articles that showed improvement in cognitive function used progressive HIFT with 80% RM at 6, 12, and 1 weeks; however, in the other articles, due to the heterogeneity of intervention protocols, measurement time points, and control group activities, mixed results were evidenced

Handgrip Strength-Related Factors in a Colombian Hypertensive Population: A Cross-Sectional Study.

(1) Background: This study determined the factors associated with manual grip strength in people with high blood pressure (HBP); (2) Methods: 219 subjects participated in this cross-sectional study, which evaluated muscle strength (manual dynamometer), sociodemographic factors, clinical characteristics, level of physical activity (International Physical Activity Questionnaire-IPAQ score), and depression (Zung's Depression Self-Rating Scale); (3) Results: The bivariate analysis found that handgrip strength in people with HPB was associated with sex (p = 0.000), age (p = 0.000), ethnicity (p = 0.019), smoking habits (p = 0.037), alcohol consumption (p = 0.004), diastolic blood pressure (p = 0.012), weight (p = 0.000), height (p = 0.000), measurement of waist circumference (p = 0.002), depression (p = 0.041), and IPAQ score (p = 0.000). Regardless of being male or female, handgrip strength was associated with age (p = 0.009), IPAQ (p = 0.000), weight (p = 0.038), height (p = 0.000), DPB units (p = 0.043), and depression (p = 0.020). The multivariate generalized linear gamma regression model showed that the coefficient with the greatest weight, regardless of sex, was age (p = 0.043), level of physical activity (24% more at high level than at low level, p = 0.031), and depression (moderate/severe depression level) associated with lower handgrip strength (p = 0.025); (4) Conclusions: Handgrip strength showed an association with level of physical activity, age, and level of depression in a middle-aged population with HBP.

Small-sided games in amateur players: rule modification with mini-goals to induce lower external load responses.

The aim of this study was to compare the acute physiological (i.e., heart rate-related variables) and neuromuscular responses (i.e., sprint and jump) and time-motion characteristics (i.e., external load variables) when modifying the game design (possession play vs. mini-goals without a goalkeeper) during 4-a-side in amateur senior football players. Male senior football players (n = 16) performed two formats of small-sided games (SSGs) in two different testing sessions (4-a-side with possession play and mini-goals rule). Differences in time-motion characteristics and physiological parameters of players were measured with the Global Positioning System (GPS), and tested before and after (pre- and post-SSG) for neuromuscular assessment. A repeated measures analysis of variance (ANOVA), with Bonferroni post-hoc test, showed that both SSG formats induced changes in sprint performance (before-after comparison) (p ≤ 0.05). Moreover, the results showed that the variables muscle oxygen saturation, rate of perceived exertion, 85-89% heart rate peak, total distance, total distances at low speed, total distances at high speed, m/min, accelerations at low speed, accelerations of ≥ 2.5 m.s-2, maximal speed, and average speed were statistically significantly different among game conditions. The players' performances are affected by the inclusion of mini-goals during 4 vs. 4 SSGs. The results provide useful information for training and task design that replicate specific physical demands (i.e., accelerations of ≥ 2.5 m.s-2, total distances at high speed or total distances at low speed).

The Influence of Pilates Exercises on Body Composition, Muscle Strength, and Gait Speed in Community-Dwelling Older Women: A Randomized Controlled Trial.

ABSTRACT: Aibar-Almazán, A, Martínez-Amat, A, Cruz-Díaz, D, Jesús de la Torre-Cruz, M, Jiménez-García, JD, Zagalaz-Anula, N, Redecillas-Peiró, MT, Mendoza-Ladrón de Guevara, N, and Hita-Contreras, F. The influence of Pilates exercises on body composition, muscle strength, and gait speed in community-dwelling older women: a randomized controlled trial. J Strength Cond Res 36(8): 2298-2305, 2022-Population aging is a global phenomenon that has wide-ranging consequences for the health of individuals, including age-related obesity, muscle loss, and a decline in muscle strength and gait speed. These alterations are associated with disability, functional decline, and mortality in older adults. The objective of this study was to analyze the effects of Pilates exercises on body composition, handgrip strength, and physical performance among community-dwelling Spanish women aged 60 and older. A randomized controlled trial of a 12-week Pilates training program was conducted. A total of 109 women were randomly allocated to either a control ( n = 54) or a Pilates ( n = 55) group. Body composition was evaluated by bioelectrical impedance. Body mass index (BMI), percentage of body fat, and height-adjusted skeletal muscle mass index (SMI) were assessed before and immediately after the intervention, as were physical performance, estimated by gait speed (timed up-and-go test), and handgrip strength. Statistically significant improvements ( p < 0.05) were observed both within and between groups for handgrip strength (Cohen's d = 0.40 and 0.52 respectively) and gait speed (Cohen's d = 0.86 and 0.87 respectively). After 12 weeks, BMI significantly decreased (Cohen's d = 0.07) only in the Pilates group. No significant differences were observed regarding SMI. In conclusion, a 12-week Pilates exercise intervention on community dwelling women over 60 years old shows beneficial effects on muscle strength, physical performance, and BMI, but failed to induce any changes on body composition.

Qigong for Muscle Strength and Static Postural Control in Middle-Aged and Older Postmenopausal Women: A Randomized Controlled Trial.

In the present study, we aimed to determine the effects of a Qigong exercise program on the muscle strength and postural control in middle-aged and older postmenopausal women. This is a randomized clinical trial (https://clinicaltrials.gov/ct2/show/NCT03989453) conducted on 125 women who were initially assigned to either an experimental group (n = 63) that performed a Qigong exercise program for 12 weeks or to a control group (n = 62) that did not receive any intervention. Muscle strength (dynamometer) and postural control (stabilometric platform) were evaluated before and immediately after an intervention period. The main findings of this study suggest that the women in the experimental group had improvements in muscle strength, mean velocity of the displacement of the center of pressure (CoP) with both eyes open and closed, and the surface sway area covered by the CoP, as well as the mediolateral and anteroposterior oscillations of the CoP, only with eyes open. The results of the present study determined that a 12 week Qigong exercise program has beneficial effects on muscle strength and postural control of middle-aged and older postmenopausal Spanish women.

Menopausal Symptoms, Postural Balance, and Functional Mobility in Middle-Aged Postmenopausal Women.

The aim of the present study was to determine the associations between the severity of the menopausal symptoms and postural balance and functional mobility in middle-aged postmenopausal women. A cross-sectional study was performed (171 participants, 57.18 ± 4.68 years). Severity of the menopausal symptoms (on the Menopause Rating Scale), postural balance (stabilometric platform) with eyes open and closed, and functional mobility (timed up and go test) were determined. A multivariate linear regression was performed, with body mass index, waist to hip ratio, age and fall history as possible confounders. Our findings showed that a greater severity of the menopausal symptoms at a psychological level was associated, under both eyes open and closed conditions, with worse postural control assessed by the length of the stabilogram (adjusted R2 = 0.093 and 0.91, respectively), the anteroposterior center of pressure displacements (adjusted R2 = 0.051 and 0.031, respectively) and the center of pressure velocity (adjusted R2 = 0.065 for both conditions). Older age was related to greater mediolateral displacements of the center of pressure with eyes open and closed (adjusted R2 = 0.45 and 0.58, respectively). There were no associations between the menopausal symptoms' severity and functional mobility. We can conclude that a greater severity of psychological menopausal symptoms was independently associated with worse postural balance in middle-aged postmenopausal women.
