Abstract

In this research, the coupling oar combined shafts of different materials was made, and then the influence on fatigue during rowing of vibration induced by using the coupling oar was evaluated. Initially, vibrations for six types of the coupling oar were analyzed. The tendency of natural frequency due to the rigidity and rubber existence in shaft was observed. The next, subjective evaluation for fatigue by using SD method, and objective evaluation by using a rowing measuring instrument were observed due to change the rowing rates by using a single scull boat. As a result, the necessity of appropriate combine of rubber into inboard side shaft and rigidity of outboard side shaft was suggested.
