Although there is a significant appreciation of sex-based differences in cardiovascular health and disease, much less is known about the effects of sex on the physiology and pathophysiology of skeletal muscle. Statistical Analysis SAS statistical software package version 9. Participants ranged in age from 60 years to 85 years top coded and were Results Sample Characteristics Demographic, social and health characteristics of the sample are illustrated in Table 1. More than 3, genes have been identified as being differentially expressed between male and female skeletal muscle In the second model, CRP was found to have a statistically significant negative association with cognitive functioning for females but not males. Muscle quality MQ was defined as the muscle strength per kilograms of mass The range in WAIS scores for men was 0. Conclusion Measures of sarcopenia are associated with lower cognitive functioning in older adults, and for females, this association may be partly due to systemic inflammation. Age was measured as a continuous variable, in years and top-coded for participants with an age of 85 years or greater. The Mammalian Myosin Heavy Chain Gene Family and Muscle Fiber Types Because the myosin motor protein is so closely linked to muscle function, it is important to consider the effects of sex on myosin gene expression. Here, we review the sex-based differences in skeletal muscle fiber composition, myosin heavy chain expression, contractile function, and the regulation of these physiological differences by thyroid hormone, estrogen, and testosterone. Muscle Quality Skeletal muscle mass of the leg and isokinetic strength of the knee extensors were used to generate muscle quality measurements. High sensitivity C-reactive protein CRP assays were performed on blood samples using a Behring Nephelometer to estimate levels of inflammation. Early studies describing muscle fiber-type composition and development did not address the potential for differences between species and sex. Sarcopenia, cognitive impairment, frailty, inflammation Introduction The pervasiveness and risks associated with physical frailty increase with age, and strongly exacerbate early-onset morbidity and mortality. Based on previous research, we hypothesize that low muscle quality sarcopenia will be positively associated with cognitive decline, and that this association will be explained by the presence of high CRP levels. Bioelectrical impedance measurements for regional bone, fat and lean-tissue content were collected by means of a whole body DXA scan. Union Physiol. Further details of recruitment, procedures and study design are available through the U. Measurements of MQ for males ranged from 6. Research has shown that systemic inflammation intensifies inflammatory responses within the central nervous system, contributing to cognitive decline 21 - Analysis was separated by sex, in order to examine differences between males and females in regards to the relationship between cognitive functioning, muscle quality and CRP. Cardiac, smooth, and skeletal are the three muscle types in mammals, with skeletal muscle being the most abundant tissue in the human body. Individuals over age 60, African Americans, Mexican Americans and low-income white Americans were over sampled. In this review, we discuss differences in skeletal muscle fiber-type composition and contractility between sexes and how these differences may be hormonally regulated. Data were collected from at-home interviews, and clinical and laboratory examinations, which took place at a Mobile Examination Center MEC. Www muscle sex com



Cardiac, smooth, and skeletal are the three muscle types in mammals, with skeletal muscle being the most abundant tissue in the human body. Although there is a significant appreciation of sex-based differences in cardiovascular health and disease, much less is known about the effects of sex on the physiology and pathophysiology of skeletal muscle. Data were collected from at-home interviews, and clinical and laboratory examinations, which took place at a Mobile Examination Center MEC. In order to account for age-related reductions in both muscle mass and muscle strength we chose to use muscle quality to conceptualize sarcopenia. High sensitivity C-reactive protein CRP assays were performed on blood samples using a Behring Nephelometer to estimate levels of inflammation. Analysis was separated by sex, in order to examine differences between males and females in regards to the relationship between cognitive functioning, muscle quality and CRP. Although there is no clear consensus concerning the clinical definition of frailty, there is concurrence that decreases in muscle mass, muscle strength and cognition are associated with manifestations of frailty 1 , 2. Age was measured as a continuous variable, in years and top-coded for participants with an age of 85 years or greater. Based on previous research, we hypothesize that low muscle quality sarcopenia will be positively associated with cognitive decline, and that this association will be explained by the presence of high CRP levels. The purpose of this study is to examine the association between sarcopenia and cognitive decline and the mediating role of inflammation. Senescence contributes to a rise in levels of interleukin-6 IL-6 , which can occur without a specific stressor, trauma or infection. In the second model, CRP was found to have a statistically significant negative association with cognitive functioning for females but not males. An analysis comparing the missing participants to the sample population indicated statistically equivalent sociodemographic characteristics for both groups. This is often the case in experimental models where sex is thought to confound results and therefore usually only males are studied. Results Sample Characteristics Demographic, social and health characteristics of the sample are illustrated in Table 1. For women, scores for the WAIS ranged from 3. Education was assessed as years of school completed, using the midpoint of reported categories. Muscle quality MQ was defined as the muscle strength per kilograms of mass These were used as control variables as they have been found to relate to frailty and cognitive decline Research has shown that systemic inflammation intensifies inflammatory responses within the central nervous system, contributing to cognitive decline 21 -

There are 11 myosin heavy chain MyHC genes that encode different myosin isoforms in mammals In addition to sarcopenia, the increase in IL-6 levels also promotes other aspects of frailty-related pathology, including cognitive decline. Furthermore, the inclusion of CRP in the second model significantly reduced the predictive power of muscle quality for females, as compared to model 1. The findings presented lay the basis for the continued work needed to fully understand the skeletal muscle differences between males and females. Sarcopenia, cognitive impairment, frailty, inflammation Introduction The pervasiveness and risks associated with physical frailty increase with age, and strongly exacerbate early-onset morbidity and mortality. Thus many of the key differences that exist between the sexes that will be presented here are likely to be the result, at least in part, of these differences in gene expression. Here, we review the sex-based differences in skeletal muscle fiber composition, myosin heavy chain expression, contractile function, and the regulation of these physiological differences by thyroid hormone, estrogen, and testosterone. In order to account for age-related reductions in both muscle mass and muscle strength we chose to use muscle quality to conceptualize sarcopenia. Union Physiol. Bioelectrical impedance measurements for regional bone, fat and lean-tissue content were collected by means of a whole body DXA scan. Sex stratified ordinary least squares regression models were utilized to estimate the relationship between muscle quality and cognitive functioning, while examining CrP as a possible mechanism and controlling for potential confounds. Participants Four hundred forty-five females and four hundred twenty-two males over age 60 from the National Health and Nutrition Examination Survey for were included. This study examined sex-specific differences in the relationship between low muscle quality and impaired cognitive functioning, while considering the role of inflammatory markers. The scale is considered to be a more precise indicator of dementia than the Mini-Mental Status Exam, and has been administered in the Health ABC study from the National institute on Aging High sensitivity C-reactive protein CRP assays were performed on blood samples using a Behring Nephelometer to estimate levels of inflammation. Because not all participants in the interview took part in the examination, participants who were included represented More than 3, genes have been identified as being differentially expressed between male and female skeletal muscle Materials and Methods Study Population The study population included a sample of males and females aged 60 and older from the U. Participants ranged in age from 60 years to 85 years top coded and were This increase may partly be due to changes in hormonal secretion related to aging which reduces their regulating effects on IL-6 and has consequences for musculoskeletal and metabolic function Although there is no clear consensus concerning the clinical definition of frailty, there is concurrence that decreases in muscle mass, muscle strength and cognition are associated with manifestations of frailty 1 , 2. Results Sample Characteristics Demographic, social and health characteristics of the sample are illustrated in Table 1. Further understanding of sarcopenia is essential, given that muscle mass and strength have implications for carrying out activities or employment, disability, physiological effects, declines in self-esteem, and falling 10 -

Individuals over age 60, African Americans, Mexican Americans and low-income white Americans were over sampled. Materials and Methods Study Population The study population included a sample of males and females aged 60 and older from the U. Skeletal muscles are composed of different types of fibers which diverge morphologically, biochemically, and functionally. The range in WAIS scores for men was 0. The purpose of this study is to examine the association between sarcopenia and cognitive decline and the mediating role of inflammation.

Senescence contributes to a rise in levels of interleukin-6 IL-6 , which can occur without a specific stressor, trauma or infection. Recently, attention has shifted to include muscle quality as an important determinant of sarcopenia and frailty, which is believed by some to be a better predictor of adverse health outcomes 13 , See other articles in PMC that cite the published article. For women, scores for the WAIS ranged from 3. Sarcopenia, cognitive impairment, frailty, inflammation Introduction The pervasiveness and risks associated with physical frailty increase with age, and strongly exacerbate early-onset morbidity and mortality. The scale is considered to be a more precise indicator of dementia than the Mini-Mental Status Exam, and has been administered in the Health ABC study from the National institute on Aging Research suggests that onset of sarcopenia is often accompanied or preceded by a pro-inflammatory state 15 - Abstract Objective Aspects of frailty such as sarcopenia and dementia are associated with a proinflammatory state; however, little research has examined the concurrence of these pathologies. More than 3, genes have been identified as being differentially expressed between male and female skeletal muscle Further details of recruitment, procedures and study design are available through the U. Table 1 Mammalian myosin genes, the proteins they encode, and where they are expressed Gene. Further research is need to examine the relationship between these frailty-related pathologies, which have substantial health and economic implications. Participants Four hundred forty-five females and four hundred twenty-two males over age 60 from the National Health and Nutrition Examination Survey for were included. Non-Hispanic whites made up Participants were allowed six trials, and the trial with the highest peak force was selected. In the second model, CRP was found to have a statistically significant negative association with cognitive functioning for females but not males. Four of these genes constitute the majority of MyHCs expressed in adult mammalian skeletal muscle: Conclusion Measures of sarcopenia are associated with lower cognitive functioning in older adults, and for females, this association may be partly due to systemic inflammation. Although there are varying degrees of MyHC isoform co-expression in single skeletal muscle fibers, individual fibers often contain a predominant MyHC isoform. The Greek term sarcopenia — meaning poverty of the flesh—has been operationalized to refer to decreases in muscle mass and strength which correlate with age 3. Furthermore, due to sex differences in frailty and levels of CRP 1 , 3 , 25 , we chose to stratify sex and examine males and females separately. Furthermore, the inclusion of CRP in the second model significantly reduced the predictive power of muscle quality for females, as compared to model 1.
