The aim of this report was to clear the change of the physical fitness and life style of 1,773 freshmen (M: 969, F: 804) of Tokyo University of Fisheries, using their fitness measurements in 1995‐2000. Though in both sex the average of their height and weight was almost same through all this period, the female freshmen’s skin fold thickness of triceps and subscapula was becoming larger in these few years. ‘Masked obesity’ might be a new problem for the female students. The freshmen’s muscular power was on the decline, but their agility and endurance were rising in both sex. In all these years approximately 70 percent of male students took exercise once or more a week, and they spent one hour or more in one time for their exercise. In female students, the frequency and duration that they spent for exercise were different on each year. Less than half of males, but most of females had breakfast everyday in each year. Most of the freshmen got 6‐8 hours sleep a day, but among females the percentage of 6 or less hours sleep gradually increased.

Forty subjects were exposed to cigarette smoke produced by a smoking machine in a climatic chamber. The degree of air pollution due to cigarette smoke corresponded to 2.5 and 1.3 ppm Δ CO. The concentrations of particulate matter, NO and NO2, were measured.

Significantly more of the younger children (81 %) than of the elder children (70%) and the students (70 %) dislike passive smoking.
