Item Preparing health teachers for health challenges in the twenty-first century(Department of Teacher Education, University of Ibadan, 1999) Moronkola, O. A.; Odelola, J. O.Item AEROBIC, ANAEROBIC AND HAEMATOLOGIC RESPONSES OF COLLEGE OF EDUCATION MALE STUDENTS TO DEHYDRATION REHYDRATION AND SUPERHYDRATION(1992) ADEGUN, J. A.The purpose of the study was to investigate the influence of dehydration, rehydration and superhydration on the aerobic, anaerobic, haematologic and some related body composition variables in College of Education male students. A repeated measures experimental design was used for the study. The subjects were twenty healthy Physical and Health Education students of Ondo State College of Education, Ikere- Ekiti. They were volunteers certified fit by the physician .before they were allowed to take part in the study. The variables tested were maximum oxygen consumption (Maxvo 2). Recovery heart rate, myocardial oxygen consumption, speed, power, packed cell volume (PVC), osmotic fragility, percent body fat and lean body weight. The subjects were pre-assessed on the selected variables. For the first condition, the subjects were dehydrated so that over 3% of the body weight of each was lost before the exercise and subsequent reassessment. Also, they were allowed two weeks after dehydration for rehydration to take place before being exposed to exercise and evaluation. For superhydration, the subjects drank 2 litres of water each 30 minutes before the evaluation took place. Nine sub-hypotheses were formulated and tested at significant level of 0.05. The data were analysed, using descriptive and inferential statistics. The descriptive statistics used were mean, range and standard deviation. The inferential statistics was the ANOVA. The method of Scheffe was used to determine where the differences. The results showed significant differences in weight, speed, recovery heart rate, maximum oxygen consumption (Maxvo 2), myocardial oxygen consumption as well as the haematologic variables of packed cell volume (PVC) and Osmotic fragility among the three levels of hydration. Superhydration affected only maximum oxygen consumption (Maxvo2). Recovery heart rate, myocardial oxygen consumption, PCV and Osmotic fragility. Other variables were not influenced significantly by the various conditions. Its concluded that dehydration was detrimental to physical performances and red blood cells while superhydration enchanced aerobic capacity.Item ANALYSIS OF OCCUPATIONAL STRESS AS RELATED TO SOME PSYCHOSOCIAL AND CAREER VARIABLES OF NIGERIAN UNIVERSITY TEACHERS(1994-12) ACHALU, E. I.This study investigated occupational stress as related to psychosocial variables of job satisfaction and psychological well-being of teachers in the first generation Nigerian Universities. Also the study assessed the differences in occupational stress experienced by the teachers with respect to career variables such job status and years of teaching experience as well as biographical characteristics namely, age and sex. The research method was a cross-sectional survey design. Cluster sampling technique was used to select teachers in the first generation Nigerian universities. A total of 300 university teachers responded to the Teacher Stress and Job Satisfaction Questionnaire as well as the General Health Questionnaire. Descriptive statistics were used to summarise the data. Multiple regression, chi-square, t-test and Analysis of Variance (ANOVA) were used to test the hypotheses at .05 level of significance. Scheffe post-hoc test was used to detect differences among groups where ANOVA was found significant. The results show that an overwhelming majority of the teachers (67.0%) were experiencing moderate levels of occupational stress while 15.0% and 18.0% were experiencing low and high levels of stress respectively. Despite this, 97.0% of the teachers reported moderate to high levels of job satisfaction with only 3.0% reporting low job satisfaction. Also a majority of the teachers (94.0%) reported moderate to high levels of psychological well-being. The reason for the findings are not clear. but it could be that the teachers have learnt to cope with the stressors encountered in the course of their work. Possibly, it could that the reported high levels of job satisfaction may have helped to moderate or reduce the impact of stress on the teachers' health. Regression analysis revealed a positive and significant relationship between occupational stress and job dissatisfaction (r=.43; P < .001); between occupational stress and psychological symptoms (r = .35; P < .001); and between job dissatisfaction and psychological symptoms (r = .45; P < .001). These findings are consistent with previous studies on teacher stress. Furthermore, there were no significant differences in total occupational stress levels with respect to age, sex and years of teaching experience. However, there was a significant difference in stress levels experienced by the teachers with respect to job status. Professors and Readers reported the lowest levels of stress followed by Senior Lecturers with junior lecturers-experiencing the most stress. The study identified the major sources of occupational stress among the Nigerian university teachers. Shortage of teaching materials, poor working conditions, heavy workload, time pressure, overcrowded classrooms, low salary and unfavourable conditions of service ranked accordingly as the most significant causes of stress. Finally, the present study indicated that occupational stress, job satisfaction and psychological health are closely related and that greater stress leads to low job satisfaction and some degree of psychological dysfunction. Thus occupational stress has negative effects on teachers' health and well-being. Moreover the results support the view in literature that teaching is a satisfying but a demanding and stressful occupation. Based on the findings of this study recommendations were made on how to reduce occupational stress and improve the health and quality of life of university teachers.Item Enhancing students' physical fitness through physical and health education teaching(Stirling-Horden Publishers (Nig,) Ltd., Ibadan., 1997) Oladipo, D.This paper critically examines the ways by which students' physical fitness can be enhanced through the teaching of physical and health Education.

The paper emphasizes that there is need to develop both the health related physical fitness components and performance-related physical fitness components of students through chalkboard classroom teaching practical teaching of various games and sports and during training for school sports. The benefit of physical fitness is not limited to an individual but it is also an index to any Country's National posture. The vigour of any Country is no stronger than the vitality and will of her Country men.
