The U.S. Department of Health and Human Services (1980) has called for improvements in the fitness of American youth. As a result, the National Children and Youth Fitness Study (Ross & Gilbert, 1985) has revealed that almost one-half of all American school-age children have sub-optimal cardiorespiratory functioning. Although adults appear to be improving their cardiovascular capacity, the fitness level of children is diminishing. Physical fitness has also been found to positively affect the psychological characteristics of adults, but research is limited on similar effects in children. / The purpose of this study was to investigate the effects of an aerobic running program on the psychological and physical fitness of eighth grade children. In addition, this study investigated the effects of an aerobic running program on the creativity of junior high school children. / Eighty-five eighth grade students participated in the study. Following random assignment to groups, the treatment subjects engaged in a five day per week structured aerobic running program. Control subjects participated in traditional, non-aerobic physical education. Using multivariate analyses of variance (MANOVA), the results revealed no statistically significant differences between groups on measures of psychological fitness. However, statistically significant differences were found between groups on measures of physical fitness and creativity. An eight week follow-up measure of aerobic capacity found no statistically significant differences between groups. / Source: Dissertation Abstracts International, Volume: 48-03, Section: A, page: 0594. / Thesis (Ph.D.)--The Florida State University, 1987.

Seven normal, healthy, male volunteer subjects were exposed to four different environmental conditions at random on four separate occasions: breathing room air with an ambient temperature of 25(DEGREES)C (NN); breathing room air with an ambient temperature of 8(DEGREES)C (NC); breathing an hypoxic gas mixture (12% oxygen in nitrogen) with a neutral temperature (HN); and breathing an hypoxic gas mixture in the cold (HC). Measurements were taken pre-exposure and every 15 min during 90 min of resting exposure and 30 min of exercise of heart rate, blood pressure, core temperature, pulmonary ventilation, and oxygen uptake. Blood samples were taken by venipuncture pre-exposure, at 45 and 90 min of resting exposure, and 5 min post-exercise and subsequently analyzed for glucose, glycerol, and lactic acid concentration. Shivering was measured by electromyography during the two cold exposures. / Hypoxia led to significant increases in heart rate, systolic blood pressure, ventilation, respiratory quotient, blood lactate, and perceived exertion during exercise, while causing significant depression of core temperature and oxygen uptake. Exposure to cold significantly increased systolic and diastolic blood pressure, pulmonary ventilation, oxygen uptake, blood glucose, and blood glycerol, while resulting in significant decreases in heart rate, core temperature, and respiratory quotient. Shivering and diastolic pressure were significantly higher, and core temperature was significantly lower, in HC compared to NC. Heart rate, systolic pressure, ventilation, respiratory quotient, and blood lactate showed tendencies to be elevated in HC compared to NC, while oxygen uptake and blood glycerol tended to be depressed. These results suggest that (1) the work output and energy requirements of the myocardium may be greater in HC than in NC, since 'pressure work' is more energetically expensive than 'volume work', in which only stroke volume and cardiac output are augmented, and (2) hypoxia concomitant with cold exposure may result in an increased reliance on shivering for heat production. / Source: Dissertation Abstracts International, Volume: 48-03, Section: A, page: 0596. / Thesis (Ph.D.)--The Florida State University, 1987.

The purpose of this study was to determine the effect of setting specific, difficult goals on performance on the Army Physical Fitness Test (APFT) by cadets enrolled in a Reserve Officers' Training Corps (ROTC) precommissioning program. The subjects used for this study were contracted Advanced Course cadets in the Army ROTC program at Florida State University who were assigned to either a goal-setting group or to a do-your-best group. / The final APFT performance data showed that setting specific, difficult goals for the goal-setting group did not result in higher performance scores than the do-your-best group cadets who were asked to do their best on the APFT. In fact, the do-your-best group cadets demonstrated a higher average improvement on the APFT. / Questionnaires designed to assess attitudes were administered to the cadets in both groups at the beginning, midway through, and after the final APFT. For the goal-setting group there was unanimous acceptance of the goals. There was, however, a slight decrease in the cadets' perception of the realistic nature of, as well as a slight decrease in their confidence of achieving, their APFT goals. They also responded with a slight decrease in the difficulty of their APFT goals. There was a surprisingly large decrease in the group's commitment to their APFT goals. On the final questionnaire the group reported that they tried hard on the APFT and that they were moderately successful on the APFT. They also preferred to set their own goals or to set them with the ROTC cadre. / For the do-your-best group the initial and mid-semester questionnaires showed a total willingness to do their best. However, on the final questionnaire one cadet reported an unwillingness to do his best. The group reported a steady decrease in their perception of the realistic nature of constantly working hard at doing their best on the APFT, and in their confidence that they could give their best effort throughout the study. The group also reported that they found doing their best to be moderately difficult. There was also a large decrease in their commitment to doing their best over the duration of the study. On the final questionnaire, 50% of the cadets reported that they had set goals despite none being set for them. / Source: Dissertation Abstracts International, Volume: 55-03, Section: A, page: 0505. / Major Professor: Dewayne J.

This study is aimed at the modelling of mesoscale processes such as up/downwelling and ice edge eddies in the marginal ice zones. A 2-dimensional coupled ice-ocean model is used for the study. The ice model is coupled to the reduced gravity ocean model (f-plane) through interfacial stresses. The constitutive equations of the sea ice are formulated on the basis of the Reiner-Rivlin theory. The internal ice stresses are important only at high ice concentrations (90-100%), otherwise the ice motion is essentially free drift, where the air-ice stress is balanced by the ice-water stress. / The model was tested by studying the upwelling dynamics. Winds parallel to the ice edge with the ice on the right produce upwelling because the air-ice momentum flux is much greater than air-ocean momentum flux, and thus the Ekman transport is bigger under the ice than in the open water. / The upwelling simulation was extended to include temporally varying forcing, which was chosen to vary sinusoidally with 4 day period. This forcing resembles successive cyclone passings. In the model with thin oceanic upper layer, ice bands were formed. The up/downwelling signals do not disappear in wind reversals because of nonlinear advection. This leads to convergences and divergences in oceanic and ice velocities which manifest themselves as ice banding. At least one wind reversal is needed to produce one ice band. / A constant wind field exerted on a varying ice cover will generate vorticity leading to enhanced up/downwelling regions, i.e., wind forced vortices. Steepening and strengthening of the vortices are provided by the nonlinear terms. As in the case of ice band formation, the wind reversals will separate the vortices from the ice edge, so that the upwelling enhancements are pushed to the open ocean and the downwelling enhancements underneath the ice. / Source: Dissertation Abstracts International, Volume: 45-11, Section: B, page: 3454. / Thesis (Ph.D.)--The Florida State University, 1984.
