Title: Physical Activity and Physiological Cost Index (PCI) in Multiple Sclerosis (MS)


Dr. Abdolhossein Parnow is assistant professor at exercise physiology. He has totally his expertise in work with physical activity and neuromuscular adaptations as well as he works on effects of physical activity and exercise training on people with Multiple Sclerosis disease and Migraine disorder. In this area, he investigate ways to be influence for these people to find economic ways that may improve the physiology function and quality of life. Since the physical activity has been shown has more advantages than other treatments, finding optimal exercise training types would be important outputs to access the goals.



Studies has been reported that regular aerobic exercise has cardiorespiratory benefits in the general population so that improves Vo2max and decreases O­2 consumption in rest and during submaximal activity such as walking. Physiological Cost Index (PCI), therefore, is a tool that measures energy cost during walking via the heart rate during walking activity, rest, and speed of walking (m/min). In addition, the dysfunction of Muscular and cardiorespiratory systems in people with Multiple Sclerosis (MS) leads to increase energy consumption cost during walking and decrease Vo2Max. MS is an autoimmune degenerative disease of the CNS and diagnosed in young adults between the ages of 20 and 40. Based on the body of evidence, recommendations have been made to include appropriate exercise prescription as an adjunct to MS treatment therapy. In addition, it has documented that PCI increases in people with MS since the HR increases during walking and at rest as well as walking speed decreases. Based on above reports, the higher value of PCI in MS results from cardiorespiratory and macular systems’ dysfunction. Our findings showed that regular aerobic exercise affects HR during walking and at rest and it improves walking speed and VO2Max in people with MS. These results, therefore, has been shows that physical activity could play main role in PCI improvement in people with MS. PCI probably helps neurologist, exercise trainers, and physiotherapist to plan optimal programs used as rehabilitation or prevention programs. By considering the benefits of physical activity, it would be presented the role of physical activity and PCI in people with MS in this workshops and be discussed how the exercise training should be design and execute.
