EXERCISE COUNTERMEASURE TO WEIGHTLESSNESS DURING MANNED SPACEFLIGHT
Journal Title: Medicina Sportiva - Year 2014, Vol 18, Issue 1
Abstract
The purpose of this Brief Commentary is to review some of the problems inherent in past and current exercise machines that were designed as attempted countermeasures to weightlessness during manned spaceflight. A countermeasure is a procedure or device that prevents or minimizes the adverse health effects of prolonged weightlessness. This commentary also will show that there is a way to effectively perform exercises in a weightless environment that will counteract or at least reduce the loss of muscular size and strength, bone mineral density, and cardiovascular function during prolonged spaceflight.
