Usually, a rowing ergometer is installed on the floor, but it has been pointed out that the kinetics, kinematics, and coordination of muscles are different from rowing motion on water. In order to solve the above problems and simulate rowing operation on water, recently a slide ergometer in which two slides move forward and backward and a dynamic ergometer in which a stretcher moves forward have been developed. The purpose of this study was to clarify the characteristics of a slide mode rowing ergometer compared to the conventionally used fixed ergometer. Subjects performed rowing movements using two different style ergometers, a rowing ergometer (Concept 2, model c indoor rower) fixed to the floor and slide ergometer on rails conditions. The subjects were 11 high school level rowers and performed 2000m race simulations under two conditions. Rowing movements were filmed by high speed video camera (250fps) from right angles beside the subject. The calculated variables were the spatio-temporal variable of the handle, the mechanical output of the handle and stretcher, as well as trunk, hip and knee angles. Stroke frequency of the slide ergometer was higher than the fixed ergometer. The slide ergometer indicated had lower handle force and higher stretcher force than the fixed type ergometer. The hip joint extension angle of the slide ergometer was larger than the fixed type. From these results, it is suggested that because the exertion of force in the upper limb was small while using the sliding condition, a large amount of exertion and movement in the lower limb was required and the involvement of the hip joint and the trunk was increased. Rowing movement performed on slide condition has characteristics as larger mechanical output in legs compared to fixed one, which might be simulated movements as on-water rowing conditions
