Sarcopenia and decreased muscle strength in the elderly woman: resistance training as a safe and effective intervention

A principle component of age-related weakness and frailty in women is sarcopenia. This decrease in skeletal muscle mass is a progressive syndrome that will affect the quality of life for elderly women by decreasing the ability to perform many activities of daily living. Strength training is known to be an effective means of increasing muscular strength and size in many populations, and can be utilized successfully to significantly improve muscle strength, muscle mass and functional mobility in elderly women up to the age of 96 years. Such exercise can minimize the syndrome of physical frailty due to decreased muscle mass and strength. Any rehabilitation or exercise program for the elderly woman would benefit from the inclusion of such a training regime.     

A comparison of three physical activity programs for health and fitness tested with older women: Benefits of aerobic activity,aqua fitness,and strength training

ABSTRACT

Inactivity has been associated with decreased quality of life of older people, and many physical activity programs are encouraged. However, the heterogeneity of the different exercise programs available is well recognized. The objective was to compare three physical activity programs (strength training, aqua fitness, and aerobic exercise) to discern the differences in the benefits achieved by each of them in older women over a period of 6 months. For that, a double-blind randomized trial sorted 347 women over 50 years old into three groups of exercise programs; they completed three sessions of evaluation that included the measurement of weight and body mass index and used the Senior Fitness Test (SFT) and SF-12 questionnaire. A t-test for related samples compared the evolution of each group, and ANOVA statistic was used to compare the effect of the different exercise programs. The results showed that women should consider performing aerobic activity up to age 60. After that age, aerobic activity or strength training can provide greater benefits.     

Body Composition and Physical Self-Concept in Older Women

ABSTRACT

We sought to determine the performance and anthropometric correlates of physical self-concept and self-esteem and to observe whether long-term resistance training would alter these variables in postmenopausal women. Forty-four nonsmoking, community-dwelling, Caucasian women aged 50–75 years participated in the study. Half of the subjects participated in a 9-month regimen of weight-bearing exercises performed 3 times per week which emphasized lower body muscle strength and power development. At baseline, total body fat was negatively associated with physical self-concept and perception of physical appearance but not with self-esteem. Perception of physical appearance improved in both exercisers and controls after the 9-month trial but was most noticeable in exercisers who had low self-esteem at baseline. The only predictor of improvement in perception of physical appearance was a decrease in lower body fat mass. Minimal or nonsignificant change in psychological measures associated with the training may be due to high initial values.     

A selective review of prenatal exercise guidelines since the 1950s until present: Written for women,health care professionals,and female athletes

BackgroundTraditional society values have long-held the notion that the pregnant woman is construed as a risk to her growing fetus and is solely responsible for controlling this risk to ensure a healthy pregnancy. It is hard to ignore the participation of pregnant women in sport and exercise today, especially in high-level sports and popular fitness programs such as CrossFit™. This challenges both traditional and modern prenatal exercise guidelines from health care professionals and governing health agencies. The guidelines and perceived limitations of prenatal exercise have drastically evolved since the 1950s.AimThe goal of this paper is to bring awareness to the idea that much of the information regarding exercise safety during pregnancy is hypersensitive and dated, and the earlier guidelines had no scientific rigor. Research is needed on the upper limits of exercise intensity and exercise frequency, as well as their potential risks (if any) on the woman or fetus.DiscussionPregnant women are physically capable of much more than what was once thought. There is still disagreement about the types of exercise deemed appropriate, the stage at which exercise should begin and cease, the frequency of exercise sessions, as well as the optimal level of intensity during prenatal exercise.ConclusionResearch is needed to determine the upper limits of exercise frequency and intensity for pregnant women who are already trained. Healthy women and female athletes can usually maintain their regular training regime once they become pregnant.     

The Effect of a Multicomponent Dual-Modality Exercise Program Targeting Osteoporosis on Bone Health Status and Physical Function Capacity of Postmenopausal Women

Purpose: Exercise is important for the prevention of osteoporosis and the reduction of fracture risk because it improves muscle mass and strength, besides improving balance. We evaluated the effect of a specific exercise program on bone mass and quality and physical function capacity in postmenopausal women with low bone mineral density. Methods: Participants (N = 125) underwent a bone mass (Dual X-ray Absorptiometry), bone quality (osteosonography), and physical functional capacity assessment. Fifty-eight of them took part in an 11-month exercise program (E), that included a multicomponent (strength, aerobic capacity, balance, joint mobility) dual-modality (on ground and in the water; alternating group and home-based exercise periods) exercise regimen. The others represented a control group (C) that did not exercise. After the exercise program all participants were reevaluated. Results: After the training program: femoral neck T-score significantly improved in E; C significantly decreased all bone quality (osteosonography) parameters, whereas E showed no differences; E significantly improved all the physical function capacity parameters, while most of them decreased or did not change in C. Conclusions: A specific exercise program targeting osteoporosis improves physical function capacity, reduces physiological bone loss, and maintains bone quality in low bone mineral density postmenopausal women.     

Prevalence of frailty and associated factors in Korean older women: The KLoSA study

The purpose of this study was to identify the prevalence of frailty in older women and its associated factors using data from the Korean Longitudinal Study of Aging (KLoSA). The level of frailty was moderate/severe in 20.2% of the women. Age, socioeconomic status, and depressive symptoms were significantly associated with all levels of frailty. Sensory function and grip strength were associated with both mild and moderate/severe frailty. The only factors associated with moderate/severe frailty were marriage status and regular exercise. Understanding the risk factors of frailty may help health care providers to deliver tailored interventions to prevent this condition and its adverse outcomes.     

Factors that may influence midwives work-related stress and burnout

Research questionTo determine the incidence and level of work-related stress and burnout in midwives and contributing and protective demographic factors that may influence those levels.Participants and methodAll registered midwives (152) working in two public hospital maternity units within the same health service district in NSW completed the Maslach Burnout Inventory Human Services Survey and a demographic survey including care model, shift work, lifestyle data and exercise level.FindingsThere was a response rate of 36.8% with 56 (56/152) midwives completing the surveys. Almost two thirds (60.7%) of midwives in this sample experienced moderate to high levels of emotional exhaustion, a third (30.3%) scoring low personal accomplishment and a third (30.3%) experiencing depersonalization related to burnout. Significant differences were found among groups of midwives according to years in the profession, shifts worked, how many women with multiple psychosocial issues were included in the midwife's workload and the midwife's uptake of physical exercise. Those midwives who had spent longer in the profession and exercised scored low burnout levels.ConclusionThe impact of years in the profession, shifts worked, how many women with multiple psychosocial issues were included in their workload and the midwife's level of exercise significantly affected how these midwives dealt with burnout and provided care for women. As the response rate was low, and the study cannot be generalised to the entire midwifery workforce but provides important insights for further research. Understanding factors related to burnout can benefit health care institutions financially and in terms of human costs, especially in view of consistent international shortages of midwives.     

A Pilot Study of the Application of the Transtheoretical Model During Strength Training in Older Women

A Transtheoretical Model (TTM) goal-setting tool was used during strength training in women. Volunteers (mean age = 69, N = 27) were assigned to a strength training only or strength training/behavior change 12-week intervention. A pre/posttest, quasiexperimental design assessed TTM constructs, Health-Related Quality of Life, and functional fitness measurements. Multiple ANCOVAs revealed significant differences between groups on lower body strength (p = .001), upper body flexibility (p = .002), Decisional Balance (p = .024,) and Stage of Change for Exercise (p = .010). Stage of change progression may be enhanced using a goal-setting tool during strength training in older women.     

Frailty selection in bivariate survival models: A cautionary note

One problem that researchers face in analyzing the survival times of groups of related individuals is selecting how the distribution of frailty—an unobserved (or not adequately observed) random factor— should be specified. Several distributions have received attention—for instance, the gamma distribution and a nonparametric N‐point, discrete probability distribution. Researchers have selected these distributions more for mathematical convenience than for their ability to represent biological, social, or economic reality, and the implications of choosing one functional representation of frailty over alternative choices have not been studied extensively. In particular, researchers have paid little attention to the type of association that exists among survival times of individuals in a group or between those of a pair under specific frailty distributions. This research paper explores the association among survival times under gamma, inverse Gaussian, nonparametric N‐point, and Poisson distributions. It shows that the pattern and strength of this association depends on how the distribution of frailty is specified.     

Is the outcome of frailty syndrome gender dependent?

ABSTRACT

We assessed the relationship between the stages of the frailty syndrome and the development of limitations in the activities of daily living, hospitalization, and death among women aged ≥80 as compared to men over the course of 12 months. The Fried criteria and selected tests of comprehensive geriatric assessment were performed in 213 participants (phase 1). After 12 months, detailed feedback on the general health and functioning was collected (phase 2). Statistically significantly higher mortality (p < .05) was found among men as compared to women. The number of deaths in the frail group was higher among frail men than frail women (p < .007).     

Women’s experiences of decision-making and attitudes in relation to induction of labour: A survey study

BackgroundRates of induction of labour have been increasing globally to up to one in three pregnancies in many high-income countries. Although guidelines around induction, and strength of the underlying evidence, vary considerably by indication, shared decision-making is increasingly recognised as key. The aim of this study was to identify women’s mode of birth preferences and experiences of shared decision-making for induction of labour.MethodAn antenatal survey of women booked for an induction at eight Sydney hospitals was conducted. A bespoke questionnaire was created assessing women’s demographics, indication for induction, pregnancy model of care, initial birth preferences, and their experience of the decision-making process.ResultsOf 189 survey respondents (58% nulliparous), major reported reasons for induction included prolonged pregnancy (38%), diabetes (25%), and suspected fetal growth restriction (8%). Most respondents (72%) had hoped to labour spontaneously. Major findings included 19% of women not feeling like they had a choice about induction of labour, 26% not feeling adequately informed (or uncertain if informed), 17% not being given alternatives, and 30% not receiving any written information on induction of labour. Qualitative responses highlight a desire of women to be more actively involved in decision-making.ConclusionA substantial minority of women did not feel adequately informed or prepared, and indicated they were not given alternatives to induction. Suggested improvements include for face-to-face discussions to be supplemented with written information, and for shared decision-making interventions, such as the introduction of decision aids and training, to be implemented and evaluated.     

Exercise training in thermo-mineral spring water has beneficial effects on hemodynamic and health-related factors in young-older hypertensive women: A randomized control trial

ABSTRACT

The aim of the study was to evaluate the effects of an 8-week aerobic training in mineral geothermal water on hemodynamic variables, VO_2max, and body composition in sedentary hypertensive women. Twenty postmenopausal women (58.55 ± 3.28 years) were divided into an exercise group (2 days/week, 30–40 minutes, 60%–75% of HR_max) and control group. Compared to the control group, a signi?cant reduction in systolic blood pressure, heart rate, rate pressure product, body fat percent, and a signi?cant improvement in VO_2max values was found. Aerobic training in thermo-mineral spring water is a safe and effective training modality in the young-older hypertensive population.     

Improvements in Quality of Life in Women after Resistance Training Are Not Associated With Age

Twenty-three women completed a resistance training program three or four days per week. At baseline and after eight weeks they completed the Vitality Plus Scale measuring exercise-related changes in quality of life. Greater scores indicated better quality of life. Significant improvements in quality of life (p < .001), upper body strength (p < .001), and lower body strength (p < .001) were observed despite training frequency. Age was not associated with quality of life or strength either pre- or posttraining. Resistance exercise three days a week improved quality of life in women, and these improvements were not influenced by age.     

Relationship Between Sarcopenia and Fracture Risks in Obese Postmenopausal Women

ABSTRACT

It is known that obesity is inversely correlated with fracture risk. It remains unclear if a low muscle mass (sarcopenia) modulates the relationship between obesity and bone mass density. Twenty-seven obese women were matched for total fat mass (± 0.5 kg) and age (± 4 yrs) and divided in 3 equal groups: class II sarcopenic, class I sarcopenic, and nonsarcopenic. Body composition (DXA) and dietary intake were measured. Our results suggest that obesity may offer some protection against osteoporosis, even in sarcopenic postmenopausal women. However, further studies are needed to examine the actual implication of these results on a clinical standpoint.     

Yoga education program for older women diagnosed with sarcopenia: A multicity 10-year follow-up experiment

ABSTRACT

This article reports a multicity yoga education program (YEP) experiment aimed at improving gait speed, muscular strength, and functional performance in Asian and African older women diagnosed with sarcopenia. Posttest gait speed and muscle strength scale scores were higher, and the six functional performance tests scores were above average for women who were from Asian cities; middle class; currently married; living with spouse, children, or kin; with good self-rated health; who regularly attended the YEP lessons and regularly self-practiced. Instructors’ self-practice record was the strongest predictor of higher posttest scores. The YEP is an effective long-term prevention for sarcopenic older women.     

Improving women’s experiences of perineal suturing: A pragmatic qualitative analysis of what is helpful and harmful

BackgroundPerineal trauma requiring suturing is increasing, along with the associated physiological and psychological morbidities for women. Provider training appears to focus more on technical aspects rather than respectful, relational care for women. Studies exploring women’s experiences have identified that how women are cared for can significantly impact upon overall experiences.AimTo identify areas of improvement to the perineal suturing process and provide robust recommendations for urgent change by investigating what aspects are most traumatic to women and which are most supportive.MethodsA pragmatic qualitative analysis of data generated from 15 in-depth interviews with women who were sutured following birth.FindingsRegardless of tear severity, what was identified as helpful included anything that made the process better by increasing feelings of trust and reassurance, and providing women with a sense of being seen and heard. Harmful experiences were identified as those that worsened the experience, by increasing feelings of fear and vulnerability and leaving women with a sense of being disregarded or disrespected.ConclusionThe study confirmed that how the suturing process is conducted can have a significant detrimental impact upon women’s short- and longer-term physical and psychological well-being.Implications for practiceAn improved experience for women is most likely with kind professionals who explain the process as it goes along, check-in regularly and validate how the women feel. Women prefer to be sutured by a known professional, only if this provider is also kind and respectful.     

Factors Associated with Long-Term Benzodiazepine Use Among Elderly Women and Men in Quebec

ABSTRACT

The goal of this study was to compare factors associated with long-term benzodiazepine use by elderly women and men (n = 1701) who participated in the Quebec Health Survey (QHS). Data from the 1998 QHS were linked with data from the administrative files of the Régie de l'assurance maladie du Québec. Results showed that elderly women were more at risk than men for long-term benzodiazepine use. Results of the multivariate logistic regression did not show a significant difference between women and men on any of the risk factors studied. Other factors such as elderly and physician attitudes deserve further study to explain differences in long-term benzodiazepine use between elderly women and men.     

Heterogeneity,dependence among causes of death and Gompertz

Heterogeneity in a population with respect to mortality, or variation in “frailty”; among members of that population, which has been discussed extensively in the literature over the last decade and a half is essential to any realistic model of dependence among causes of death. The main problem then is the development of a mortality model incorporating heterogeneity and cause of death which is both realistic and of manageable proportions.

In a recent paper (J. H. Pollard, 1991), it has been shown that many life table results are remarkably insensitive to the strict shape of the mortality curve, at least for more developed populations, and that accurate approximations can in many cases be obtained knowing only the mortality rates at two representative ages (e.g. 50 and 70). These results and the Gompertz “law”; of mortality can be used to develop manageable approximate formulae for the expectation of life under heterogeneity and correlation among the causes of death. The formulae are confirmed by simulation.

Numerical results indicate, somewhat surprisingly, that the effects of correlation among causes of death, even at quite high levels, on expectation of life and changes on expectation of life when particular causes of death are reduced or eliminated are relatively minor.
