Abstract

Osteoporosis is a chronic disease of major public health concern. Characterized by low bone mass and increasing risk for fracture, osteoporosis occurs to a greater extent in women. Resistance training is a mode of exercise that can be used to build peak bone mass during youth, thereby preventing osteoporosis later in life. Our aim was to evaluate the effectiveness of a resistance training protocol designed to apply loads to the hip and spine in men and women. We recruited recreationally active men (n = 12) and women (n = 12), ages of 18-23. An additional 10 participants (5 men, 5 women) served as controls. Volunteers completed questionnaires to assess health history, physical activity, dietary intake, and menstrual history. The training program was performed for 24 weeks, on 3 nonconsecutive days per week, including exercises for the upper, lower, and core musculature, marked by an undulating periodization varying between 67 and 95% of 1 repetition maximum (1RM) on the multijoint exercises of bench press, squats, and deadlifts. Dual energy X-ray absorptiometry (Hologic Explorer, Waltham, MA, USA) was used to assess bone mineral density (BMD, g · cm(-2)). A 2-tailed analysis of covariance, controlling for body mass index, reveal...Continue Reading

Biomechanics

Biomechanics examines the generation of internal forces within the body and investigates the effects and control of forces that act on or are produced on tissues. Here are the latest discoveries.
