Influence of menopausal status on the main contributors of muscle quality.

Background: Muscle quality is a strong independent predictor of physical function. Body mass and fatness, muscle mass and cardiorespiratory fitness are known to influence muscle quality.

Objective: To identify the contributors of muscle quality in young and postmenopausal women and whether hormone replacement therapy (HT) could influence this relationship at the age of menopause.

Identifying recreational physical activities associated with muscle quality in men and women aged 50 years and over.

Background: Several studies conducted in a laboratory-related environment have shown that exercise is associated with increased muscle quality in older adults. The aim of the present study was to investigate whether recreational exercise may also be associated with muscle quality in men and women aged 50 years and over.

Methods: Data are from 312 individuals (215 women) aged 50 years and older.

Relationship between protein intake and dynapenia in postmenopausal women.

Objective: The purpose of this study was to investigate the relationship between protein intake and dynapenia.

Design: A cross-sectional/observational study.

Setting: Department of Kinanthropology at the University of Quebec at Montreal.

Relationship between long sleep duration and functional capacities in postmenopausal women.

Study Objective: The purpose of the present study was to examine the relationship between long sleep duration and functional capacities.

Methods: We conducted a cross-sectional study at the Department of Kinanthropology at the University of Quebec at Montreal. Forty eight non-frail postmenopausal women aged between 49 to 75 years were recruited using advertisements in local papers.

Is functional capacity related to the daily amount of steps in postmenopausal women?

Objective: The aim of this study was to investigate the relationship between functional capacity, muscle function, and daily step count in postmenopausal women.

Methods: Fifty-seven postmenopausal women aged 50 to 70 years were recruited. Body composition (body weight, body mass index, fat mass, and skeletal muscle mass), energetic metabolism (maximal oxygen consumption, total energy expenditure, daily step count), and functional capacity (muscle strength, muscle quality, chair stand, balance and alternate step tests) were measured.

Effects of tai chi training in dynapenic and nondynapenic postmenopausal women.

Objective: The purpose of the present study was to investigate the effects of a 12-week tai chi program in type I dynapenic and nondynapenic postmenopausal women.

Methods: Sixty-two postmenopausal women were recruited. Body composition, handgrip strength, functional capacities, cardiorespiratory functions (forced expiratory volume in 1 s and oxygen consumption per unit time peak), and quality of life (36-item Short-Form Health Survey) were measured before and after the intervention.

Relationship between dynapenia and cardiorespiratory functions in healthy postmenopausal women: novel clinical criteria.

Objective: Muscle strength seems to be a better indicator of physical limitations than skeletal muscle mass is. The purpose of this study was to investigate, using a new developed clinical tool, the relationship between type I dynapenia and cardiorespiratory functions in postmenopausal women.

Methods: Forty-six postmenopausal women were recruited and divided into two groups (dynapenic vs nondynapenic).
