Abstract:
The aim of the current study was to investigate the relationships between limb muscular strength and bone mineral density (BMD) in a group of elderly subjects with low skeletal muscle mass index (SMI).55 elderly Lebanese subjects (35 women and 20 men) participated in the current study. Handgrip, one-repetition maximum (1-RM) dumbbell curl (1-RM biceps), 1-RM lying one arm triceps (1-RM triceps), 1-RM calf raise, 1-RM leg extension and 1-RM leg curl were evaluated using validated methods.In both genders, 1-RM biceps, 1-RM triceps, 1-RM leg extension and 1-RM leg curl were positively correlated to total hip BMD. The current study shows that limb muscular strength is positively correlated to hip BMD in elderly subjects with low SMI. This may have clinical implications in the field of osteoporosis prevention in elderly subjects with low SMI.

01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
01:09Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
01:25Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
