Muscle forces or gravity : What predominates mechanical loading on bone ? : Introduction

Mechanical basis of bone strength: influence of bone material, bone structure and muscle action

This review summarises current understanding of how bone is sculpted through adaptive processes, designed to meet the mechanical challenges it faces in everyday life and athletic pursuits, serving as an update for clinicians, researchers and physical therapists. Bone's ability to resist fracture under the large muscle and locomotory forces it experiences during movement and in falls or collisio...

Bone Health: Part 2, Physical Activity

Mechanical loading is a crucial factor for maintaining skeletal health. Physical activities, exercise, and sports provide a wealth and variety of mechanical loads to bones, through muscle forces, ground reaction forces, and other contact or impact forces. Weightbearing activities can be effective exercises to enhance bone health—particularly, those that involve jumping and impact loads (with gr...

Ground reaction forces during locomotion in simulated microgravity.

BACKGROUND Significant losses in bone density and mineral, primarily in the lower extremities, have been reported following exposure to weightlessness. Recent investigations suggest that mechanical influences such as bone deformation and strain rate may be critically important in stimulating new bone formation. HYPOTHESIS It was hypothesized that velocity, cadence, and harness design would si...
