Sarcopenia in Menopausal Women: Current Perspectives.
peer reviewedMenopause is associated with hormonal changes, which could accelerate or lead to sarcopenia. Functional impairment and physical disability are the major consequences of sarcopenia. In order to hamper these negative health outcomes, it appears necessary to prevent and even treat sarcopenia, through healthy lifestyle changes including diet and regular physical activity or through hormonal replacement therapy when appropriate. Therefore, the purpose of this narrative review will be 1) to present the prevalence of sarcopenia in postmenopausal women; 2) to address the risk factors related to sarcopenia in this specific population; and 3) to discuss how to manage sarcopenia among postmenopausal women
Effects of Citrulline alone or combined with exercise on muscle mass, muscle strength, and physical performance among older adults: a systematic review.
[en] PURPOSE OF REVIEW: To Establish the potential of Citrulline supplementation (CIT) combined or not with exercise on muscle function and physical performance via a systematic review of randomized controlled trials (RCTs) in human aged 50 years and older.
RECENT FINDINGS: Based on Preferred Reporting Items for Systematic Reviews and Meta-analysis guideline, 103 references have been identified. Among this number, only six RCTs (250 participants) matched the inclusion criteria and were included in the present systematic review. Among the included studies, five of six reported beneficial effects of CIT on muscle mass. Then, four of six studies reported CIT effects on muscle strength but also that CIT when combined to exercise results in further improvements in upper muscle strength. Finally, three of six studies reported beneficial CIT effect on physical performance and suggested that CIT with exercise displayed greater improvements in walking speed than exercise alone.
SUMMARY: CIT supplementation seems to be able to improve muscular and physical factors in frail elderly people (malnourished, hypertensive, obese, dynapenic-obese) compared to placebo. More importantly, CIT combined to exercise is more efficient than exercise or CIT alone. However, because of the small number (six) and heterogeneity (dose, duration, population) of the studies realized in older adults, further studies are needed to confirm its promising potential
Reference Standard for the Measurement of Loss of Autonomy and Functional Capacities in Long-Term Care Facilities
peer reviewedThe vast majority of people living in long-term care facilities (LTCFs) are octogenarians (i.e., in Québec, 57.4% of the residents are age 85 or older, 26.2% are between age 75 and 84, 10.7% are between age 65 and 74, and 5.7% are below age 65 (1)), who are affected by a great loss of physical or cognitive autonomy due to illnesses and are unable to maintain their independence, safety and mobility at home. For the majority of them, their last living environment will be a LTCF. Moreover, the annual turnover in LTCFs is one-third of all residents (2) while the average length of stay is 823 days (1). Therefore the main challenges for caregivers in LTCFs are the maintenance of functional capacities and preventing patients from becoming bedridden and isolated. Measuring the level of autonomy and functional capacities is therefore a key element in the care of institutionalized people. Several validated tools are available to quantify the degree of dependence and the functional capacities of older people living in long-term care facilities. This narrative review aims to present the characteristics of the specific population living in long-term care facilities and describe the most widely used and validated tools to measure their level of autonomy and functional capacities
Exercise Guidelines to Counteract Physical Deconditioning in Long-Term Care Facilities: What to Do and How to Do It?
peer reviewedWith age, older adults experience a decrease in muscle function and changes in body composition, which raise the risk of functional incapacity and loss of autonomy. These declines are more pronounced in older adults living in long-term care (LTC) facilities than those living in the community (ie, sarcopenia prevalence: ∼41% vs ∼10%; obesity prevalence: 30% vs17%). The main cause of these declines is chronic diseases, which are a driver of higher rates of sedentary behavior (85% of time in LTC). Exercise, however, is recognized to help counteract age-related decline, yet it is not integrated into clinical practice
