The crew on board need strong physical and spiritual strength and more necessity of exercise than those on land, but they usually find it difficult to carry out various types of exercise owing to lack of sporting equipment and facilities. Inboard exercise can be done besides the terrible ship rolling which has a great effect on physical strength exercise. The purpose of this paper is to suggest to the crew on board method and pattern of exercise for the improvement of their strength and endurance, and to enable the crew to make use of the suggested exercise. and finally to make it possible for them to improve their physical and to lead a healthy lives. For the improvement of the crew's strength and endurance, istonic and ismetric training were carried out. This paper suggests an exercise pattern with the application of the overload principle in order to strengthen physical power and endurance through the is tonic training. On the other hand, this paper also suggests an exercise pattern with and without sporting equipment so as to resist with maximum strength or to train to the best of physical ability with light overload through the isometric training. Finally, this paper tries to provide six training programs that allow complex training affer individual training. According to the given programs, the crew must carry out training more than three or four times a week and check the degree of the improvement of endurance during the period of training. The programs are also designed to let the crew know about stress of exercise through the check of the individual's changes in heartbeat rate while trainging and to intensify the function of the cardiorespiratory by increasing the hearbeat rate 60 or 70 times during the training more that of the state of rest.

To improve the ability in Standing Broad Jump, for 9 weeks, the experimental group have been made to practice jumping from the mat changing the height of the bar and the distance between the start-point and the bar, while the comparative group have been made to practice jumping from the mat onto the vaulting box, on which the comparative group practiced flight-gorm and landing. The result of the experiment is as follows: 1) The experimental group, by the help of subsidiary apparatus, have got used to Hitch Kick Style, in which jumped with his knees most folded, to jump higher, putting the center of gravity of the body forward, drawing the thigh towards the breasts, and stretching the legs out before landing, to reach far. 2) The comparative group, on the top of the vaulting box, have practiced Hang Style, but the measument of the record was too difficult to be correct. 3) The training method by practicing subsidiary events and using subsidiary apparatus have proved more effective than the training method by practicing Standing Broad Jump itself. 4) In standing Broad Jump, the students with the high stature and long upper thigh but light weight and small thigh Circumference have proved to have an advantage. 5) In vertical Jump, the students with high stature or with long lower thigh and long upper thigh have proved to have an advantage. 6) Practicing hopping on both feet on the steps has proved to be helpful in improving the record of Standing Broad Jump rather than that of Vertical Jump. 7) Between standing Broad Jump and Vertical Jump, the experimental group have proved to have a correlation(r=0.42 (p 0.01)), while the comparative group had a correlation(r=0.57 (p 0.01)). Therefore it can be said that there must be a correlation between them. 8) While the experimental group have proved to have an improvement of 0.46cm in Standing Broad Jump, 9.61cm in Vertical Jump, the comparative group have proved to have an improvement of 4.39cm in Standing Broad Jump, 7.86cm in Vertical Jump.

The purpose of this study was to explore the nature of the relationship between several factors representing the mental health enumerated in the psychology literature and the dadaptability to group life which all of th KMU students encounter. An empirical study was carried out to examine not only the differences in mental health of 4 kinds of students groups but also the impact of interaction which mental health affects to the adaptability to group life among grades. The several factors of the mental health can be utilized in suggesting the theoretical bases for the countermeasures of the effective group life along with the motivation of KMU students. The data investigating the impact of interaction between mental health and the adaptability to group life were collected from 537 KMU students selected from 4 different kinds of population-(1) Freshman group (2) Sophomore group (3) Junior group (4) Senior group-by the use of questionnaire method and interview. The 2-way analysis of variance (MANOVA) were used to analyze the data. The results of this study were found as follows; (1) There are significant difference in the cognition of gloom, personal sensitiveness, anagonism, anxiety and total score among 4 grade groups, (2) The freshmen group and the sophomore group have perceived gloom, personal sensitiveness, antagonism, and total score more acutely than the junior group and senior group have. (3) There are significant differences in perceiving an obession and personal sensitiveness according to the adaptation types to the group life; adaopted type, non-adapted type. The non-adapted group has recognized an obsession and personal sensitiveness more seriously than the adapted group has. (4) The interaction between grades and the adaptation status doesn't have an direct influence on the mental health.

This study investigated the correlation of physique factor( standing height, body weight, chest girth, body surface ) and vital capacity upon records of swimming discipline at sea water. The subjects are 194 sophomore students of Korea Maritime University who participated in the swimming discipline. The swimming records were divided into three groups - higher, middle and lower group. The results from this investigation are as follow ; 1. The standing height was above the average on the A, B+ record, body weight was above on the A+, A record, and vital capacity was above on the A+, A, B+, C record respectively. 2. The standing height, body weight, chest girth, body surface, vital capacity was significantly correlated between record P < 0.05 and P < 0.01. Therefore the higher record group has better physique factor and vital capacity than the middle or lower record group. 3. The standing higher of the higher record group was significantly correlated with body weight(0.514), body surface(0.768) and vital capacity(0.427), and body weight was significantly correlated with chest girth(0.525), body surface(0.940) and vital capacity. This standing heiht of the middle record group was sigificantly correlated with body weight(0.509) and body surface(0.779), and body weight was significantly orrelated with chest grith(0.618) and body surface(0.927). The standing height of the lower record group was significantly correlated with body weight(0.595), chest grith(0.363), body surface(0.802) and vital capacity(0.250), and body weight was significantly correlated with chest grith(0.678) and body surface(0.952).

The questionnaire survey for the seamen who had been in service on the ocean going vessels was conducted and the results are fumed out as the followings. Total number of seamen who had answered the questionnaire was 64 persons and the distribution status of service period group was identified as 16 persons for each of 4 groups; the group was classified as the group of less than 5 years, 5 - 10 years, 10 - 15 years, and more than 15 years. 1. Working conditions Working hours in a week was identified as 44-56 hours(45.3%) and the number of 45.3% of the seamen answered the working hours in week is more than 56 hours. The seamen of 25.0% are unsatisfied or very unsatisfied with their vocation. The seamen of 65.6% are smoking, and 45.3% of them drink. The seamen of 44.,3% drink once or more in a week. And the seamen of 67.2% do not take any exercise in a week. 2. Contribution to the seamen's fatigue and subjective symptom The most contributive factor to the seamen's fatigue was identified as the short of sleeping(21.5%), overwork(19.2%), poor working conditions (18.6%), and the friction in human relations also becomes one the contribution to the fatigue(14.0%). The subjective symptom by fatigue was identified as the feeling of languid, sleepy and tiredness of eyes. 3. Characteristics of the seamen's physical strength and Interrelations The grip strength and back strength of the seamen whose service period is less than 5 years were measured as 40.44kg and 127.8kg. The sit ups in the group of service period less than 5 years was measured as 36.84 times, and the vertical jump for the seamen in this group was measured as 46.55cm. The closed-eyes foot balance was measured as 33.64 seconds in the group of service period between 5 and 10 years, and side-step was measured as 35.31 times in the group of service period less than 5 years. The standing trunk flexion was measured as 10.54cm for the seamen whose service period is between 10-15 years, and the trunk extension was measured as 50.70cm for the seamen whose service period is less than 5 years. And the step test of the seamen whose service period is between 10-15 years was measured as 54.44 numbers, and the number of flickers of the seamen whose service period is less than 5 years was measured as 32.94.
