Foundations of Space Biology and Medicine. Volume 2, Part 3, Chapter 3. Impact Accelerations

Abstract

The problem most specific to space medicine is the potential change of impact tolerance due to reduced bone mass and muscle strength caused by prolonged weightlessness and physical inactivity. Considerably more research is required as space missions will be extended over many weeks and months. The relationship between bone strength, bone mass and muscle strength must be explored as a function of gravitational load, isotonic and isometric exercise, time pattern and diet; for osteoporosis of disuse appropriate time scaling factors for bone dynamics as a function of gravitational exposure and activity time patterns must be established relating animal experiments to human conditions. Changes in injury patterns due to these changes in the musculoskeletal system must be known and understood.
