Physical activity, muscle function, falls and fractures

Physical activity, muscle function, falls and fractures

STUDY DESIGN A thematic review. OBJECTIVES To evaluate if physical activity enhances muscle strength, improves balance, and reduces the fall frequency and the fracture incidence. BACKGROUND One of the major medical problems of today is the increasing incidence of fragility fractures. Muscle strength and fall is one of the major determinants of a fracture. If physical activity could increase...

Objective measures of physical activity, fractures and falls: the osteoporotic fractures in men study.

OBJECTIVES To determine the association between objectively measured physical activity (PA), fractures, and falls. DESIGN Longitudinal cohort study. SETTING Six U.S. clinical sites. PARTICIPANTS Two thousand seven hundred thirty-one men with a mean age of 79.

The Association of Food Intake and Physical Activity with Body Composition, Muscle Strength and Muscle Function in Postmenopausal Women

Background and Objectives: Sarcopenia is explained as age-related reduction in muscle mass and performance. Some of the most important risk factors for sarcopenia include age, malnutrition, and sedentary life style. The aim of this study was to investigate the association of food intake and physical activity with body composition, muscle strength and muscle function in post-menopausal women. ...

Physical Exercise for Prevention of Falls and Fractures

Responses of Muscle Mitochondrial Function to Physical Activity: A Literature Review

Skeletal muscles play an active role in regulating the metabolic homeostasis through their ability for relating to adipose tissue and endocrine hormones. Contraction of the skeletal muscle leads to increased release of several myokines, such as irisin, which is able to interact with the adipose tissue. Physical activity promotes the irisin mechanism by augmenting the peroxisomes (PGC1-α) in the...
