The purpose of this investigation was to determine the effects of roller ski and running exercises on Energy Output, MET, Fat and carbohydrate metabolism of cross- country skiers. The Purpose was to determine different modes of exercise. Dry land exercise devices which roller skiing and running. It was hypothesized that submaximal roller ski exercises could develop endurance capacity as running exercise. All analyses were indicated there are no significant differences between the exercises modes in Q, MET, and CHO metabolism except fat metabolism between 10th and 15th minutes in running exercises. The reason for increasing fat metabolism in 10-15 minutes of exercise may be explain to lowering exercise intensity or fatigue mechanism in that intensity. As intensity of exercise increase CHO using also increase by the same way. Economy the oxygen cost of walking or running at varying speeds. The basic generalization about economy is that, over a wide range of velocities, the energy cost is rectilinearly related to the speed.3 On the other hand, differences among individuals in terms of running economy are often extensive, ranging from 20-30%, in subjects of equal training and performance status. The reason for this observation has not been determined.2 Roller ski and running exercises has different velocity and fatigue. CONCLUSION: The results suggested that fat metabolism in running exercise between 10-15 minutes significantly increase, while in two exercises modes Q, Met, and CHO metabolism increased at the same degree.
