Longitudinal Changes in Selected Physical Capabilities: Muscle Strength, Flexibility and Body Size

Longitudinal changes in selected physical capabilities: muscle strength, flexibility and body size.

OBJECTIVES first, to record, in a representative sample of older men and women, longitudinal changes in (i) maximal voluntary strength of the handgrip muscles, (ii) maximal range of movement in the shoulder joint and (iii) body weight and skeletal size; second, to explore associations between the changes in muscle strength and both customary physical activity and health outcomes. DESIGN longi...

Longitudinal Changes in Muscle Strength, Flexibility and Knee Laxity during Puberty in Girls

From the onset of puberty, females are at a greater risk of sustaining a non-contact anterior cruciate ligament (ACL) rupture than males [1]. One factor commonly associated with greater ACL injury risk is increased passive knee laxity and the accompanying decrease in knee joint stability [2]. Females tend to display fluctuations in knee laxity across the menstrual cycle [3] as well as greater a...

Longitudinal muscle strength changes in older adults: influence of muscle mass, physical activity, and health.

The longitudinal changes in isokinetic strength of knee and elbow extensors and flexors, muscle mass, physical activity, and health were examined in 120 subjects initially 46 to 78 years old. Sixty-eight women and 52 men were reexamined after 9.7 +/- 1.1 years. The rates of decline in isokinetic strength averaged 14% per decade for knee extensors and 16% per decade for knee flexors in men and w...

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. ...
