Abstract
In this report, a part of physical fitness data of seamen on active service was ed. Present. The subjects were seamen of 114 officers and 212 ratings. Measured items were "Side Step Test", "Vertical Jump" and "Zig-Zag Dribble" from the "Adult Physical Fitness Test" by The Ministry of education, and the measurements were administered in 1968. As the result, it was found that all the data on seamen were inferior to the data on the average Japanese adults obtained in the same year by The Ministry of Education except the fact that there was no difference in "Side Step Test" of any age of officers and in "Zig-Zag Dribble" of officers older than 45 years compared with the respective data on the average Japanese. As for the comparison between officers and ratings, officers are significantly superior to ratings in "Side Step Tests" and in "Zig-Zag Dribble", and "Vertical Jump" also was in the same. From the results, specific weight of seamen which was superior to the Japanese average was considered to be one of the reasons for the difference between seamen and the average. Japanese Investigations in the aspect of mental ability especially on seamen might be necessary.
