| Research Abstract |
In 2004, we wrote a paper and made a presentation based on previously collected data. This data was analyzed from a longitudinal viewpoint to investigate changes in the physical fitness of early teenagers over one year. The relationship between fitness and related psychological factors were categorized into the following three categories : physical fitness and lifestyle ; physical fitness and mental health ; and physical fitness and motivation for physical activity.
Regarding the physical fitness and lifestyle category, the lifestyle of most 5^<th> and 6^<th> grade children affected their level of physical fitness, and those with a healthy lifestyle demonstrated a high level of fitness. However, it became clear that most lifestyles did not result in improved fitness over one year. Exceptionally, children who ate breakfast and exercised after school demonstrated a higher fitness level than those who did not and it is clear that these two factors strongly impact physical fitness. Also, re

garding the relationship between physical fitness and mental health, we pointed out that overall subscales (physical symptoms, depression, social anxiety, impulsiveness and deficiency) had a low impact on physical fitness over a one-year period. However, in boys, ‘social anxiety' was found to have a great explanatory value. It can be supposed that boys in their early teens who demonstrate high 'social anxiety' will exercise less with friends and therefore receive lower scores in physical fitness tests a year later.
In regard to motivation for physical activity, physical fitness scores of the 2002 test were taken as dependent variables, and subscale scores of the Motivation Inventory for Physical Education test in 2001 were used as independent variables. Multiple regression analysis found that the Self Concept Scale and Failure Avoidance Scale had a high explanatory value for boys and girls respectively. Hence, for boys, a sense of superiority exceeded their sense of inferiority, and the Self Concept Scale had an explanatory value related to their physical fitness. For girls, a sense of inferiority exceeded a sense of superiority, and thus the Failure Avoidance Scale seemed to be the determining factor. Less
