Objective:
To determine the importance of physical activity in the occurrence of osteoporotic fracture and to examine the impact of exercise frequency on osteoporotic fracture among a national sample of women aged 50 years and older.
Design And Setting:
This study involved female participants in the Third National Health and Nutrition Examination Survey (NHANES III), Phase 1.
Subjects:
The sample consisted of 2,325 women aged 50 years and older who were interviewed for Phase 1 of NHANES III.
Measurements:
Predictor variables that were examined in this study included heredity, age, race, body mass index, physical activity, smoking status, alcohol use, and dairy product intake. Multivariate analysis was conducted.
Results:
Race, age, body mass index, and inactivity were significant risk factors Predicting the occurrence of osteoporotic fracture.
Conclusions:
Athletic trainers in clinical settings are in an ideal position to educate female patients about risk factors for osteoporotic fracture. The clinical athletic trainer may incorporate balance training, generalized strengthening, and other fall-prevention activities into rehabilitation programs in order to help prevent osteoporotic injuries.

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...

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...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

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...
