Maximal Aerobic Exercise of Individuals with Multiple Sclerosis Using Three Modes of Ergometry
This study examined metabolic and cardiopulmonary responses during maximal effort exercise in persons with multiple sclerosis (MS) using arm cranking (ARM), leg cycling (LEG), and combined arm/leg cycling (LEG/ARM). Ten individuals with MS were matched to ten, non-MS persons. Peak oxygen uptake (VO(2peak)) was determined via a leg/arm ergometer on 3 separate days. VO(2peak) was significantly higher for the non-MS group for the ARM and the LEG/ARM tests (p<.05), but not for the LEG test. Heart rate (HR) at peak exercise for the MS group was 89, 86 and 91% of age predicted maximal HR during ARM, LEG and LEG/ARM exercise, respectively. The non-MS group was able to reach 96% of its age-predicted HR(max) during all protocols. The addiditive physiologic responses during combined arm/leg ergometry could be advantageous for fitness training persons with MS by dispersing the exercise over a larger muscle mass, placing less stress on any one group. This may translate into improved endurance for ambulation and/or performance activities of daily living.
