| This condition is known as orthostatic intolerance and is caused primarily by cardiovascular deconditioning that can occur in space. |
| This further demonstrates the effect of physical activity on improving strength secondary to deconditioning. |
| Affected children may restrict activity due to parental concern, musculoskeletal pain or deconditioning. |
| As well, physical disability can result in deconditioning, adding further to the problems of both fatigue and weakness. |
| Bone demineralization and generalized muscular deconditioning occur in all people who experience bed rest, immobility, or sedentary lifestyles. |
| Because skeletal muscles become deconditioned, the same state of deconditioning in respiratory muscles can be expected. |
