According to literature, particularly from data obtained from the World Health Organisation, physical inactivity or sedentarism is one of the leading causes of the major non-communicable diseases, which contributes substantially to the global burden of diseases, death and disability. The burden of mortality, morbidity and disability attributable to non-communicable diseases is currently greatest and is continuing to grow in the developing countries. Most declines in physical activity are during the transition from high school to college or university. The aim of the study was to ascertain perceptions of physical activity, specifically / perceived benefits of, perceived barriers and perceived helpful motivational factors to physical activity among tertiary institution students in Rwanda, and to find out whether demographic and background characteristics have an influence on these perceptions.

The purpose of this study was to determine if isokinetic testing could be used as an effective means of assessing a players potential to play a certain position. The subjects were twenty four male division IA college football players. The Cybex 340 isokinetic testing device, twenty and forty yard dash, and standing broad jump were used to collect data. An analysis of variance test with repeated measures was used for the statistical analysis (ANOVA). Based on the findings of this study, no significant difference was found between offensive and defensive lineman, through isokinetic testing. However, a significant difference was found between the groups in the twenty and forty yard dash, and in the standing broad jump. Significant differences in these areas may have been attributed to a significant difference in body weight between the two groups tested. / School of Physical Education

While a great deal of research has been directed towards investigating the age-related decline in V02max, the effect of physical activity on the age-related decline in V02max has not been clearly established. Therefore, the purpose of this study was to examine the relationship between physical activity and the age-related decline in maximal oxygen consumption (VO2max) in apparently healthy individuals. In order to assess the effects of physical activity on the age-related decline in V02max, physiological data was obtained from 142 former participants (116 men and 26 women) (40 ± 8.0 years), in the Ball State University Adult Physical Fitness Program across an average of 12 ± 4.5 years. The subjects were divided into three physical activity group categories depending on their self-reported physical activity status at the time of the first and follow-up test. Those subjects who were sedentary at the first and last test were designated as SED-SED. Those who reported sedentary at the first test and active at the last test were designated as SEDACT and those who were physically active at the time of both tests were designated as ACT-ACT. The data from the analysis revealed that the rate of decline in V02mx expressed as change per year among adult men varied as a function of their reportedphysical activity habits. Those men designated as SED-SED and ACT-ACT experienced a statistically significant decline (p<0.05) in V02max during the follow-up period, while, those men designated as SED-ACT maintained their V°2max. The rates of the change in V02max (ml-kg- 1•min-1) for the men were -0.45, 0.03 and -0.22 ml•kg-l-min-1•yr1 for the SED-SED, SED-ACT and ACT-ACT groups respectively. The percent decline in V02max were 6%, 11% and 2% respectively. A statistical comparison of the rate of change among physical activity groups indicated a difference between the SED-SED and SED-ACT groups (p<0.05). Within the limitations of this study, these data suggested that there was no statistically significant difference in the rate of change in V02max (ml•kg-1•min-1-yr1) between the SED-SED and ACT-ACT physical activity groups. However, when presented as percent change per decade, the decline for those men who were sedentary at both time points was twice that of those men who reported an active lifestyle at both time points. Although the rates of change were not different for the SED-SED and ACT-ACT physical activity groups, those men with a physically active lifestyle maintained their aerobic power advantage as compared to sedentary men who remained sedentary. Furthermore, sedentary men who took up an active lifestyle had offset the decline in V02max (ml•kg-1•min-1) attributed to physical inactivity.The rates for the change in V02max (ml•kg-1•min-1-yr1) for the women were -0.36, 0.20 and -0.21 (ml•kg-1•min-1-yr1) for the SED-SED, SED-ACT and ACT-ACT groups respectively. While these changes were similar in direction and magnitude to those observed for the men, there were no statistically significant differences among the female groups (p>0.05). Therefore the results from the present study were inconclusive for women possibly due to the low sample size (n=26). / School of Physical Education

The purpose of this paper was to monitor the heart rates of-first, third, and fifth grade students during physical education classes to determine if the classes contribute to improvement in cardiovascular fitness levels. The study determined the average heart rate of students in physical education classes and determined the percent of time the heart rate remained in, above, and below a predetermined heart rate range of 140 to 180 beats per minute.Students from seven schools were involved in this study which included: 338 first graders, 236 third graders, and 217 fifth graders. Each school was visited three times.The measurement of heart rates was accomplished by placing a heart rate monitor on each student during their regular physical education class. The results indicated that the average heart rate for all first graders was 142.28 beats per minute (bpm), for all third graders was 141.68 bpm, and for all fifth graders was 142.85 bpm. The percentage of time spent in the pre-determined heart rate range for first grade students was 39.98%, third grade was 37.78%, and 40.64% for fifth grade. The percentage of time spent above the pre-determined heart rate range for first grade was 15.59%, 15.76% for third grade, and 13.91% for fifth grade. The percentage of time spent below the predetermined heart rate range for first grade was 43.99%, for third grade 46.32%, and 47.00% for fifth grade. The above findings revealed that the average heart rates did increase, although when further examining the percentage IN, ABOVE, and BELOW the pre-determined heart rate range the figures indicated that heart rates were not maintained at an appropriate level of intensity for the adequate time needed to increase cardiovascular fitness levels. If cardiovascular fitness is a goal in these classes, changes in class drills and games will be required to accomplish this goal. / School of Physical Education

Background and objectives: Physical fitness and stress resilience may influence the risk of gastrointestinal (GI) disease. High physical fitness level may reduce levels of systemic inflammation while psychosocial stress exposure can increase inflammation levels and intestinal permeability. The main objectives are to evaluate if poorer physical fitness and stress resilience in adolescence are associated with a raised risk of inflammatory bowel disease (IBD), peptic ulcer disease (PUD) and GI infections in adulthood and to assess evidence of causality. Materials and methods: Swedish registers provided information on a cohort of approximately 250,000 men who underwent military conscription assessments in late adolescence (1969 –1976) with follow-up until December 2009 (up to age 57 years). Cox regression evaluated the associations of physical fitness and stress resilience in adolescence with subsequent GI disease risk in adulthood. Results and conclusions: IBD: Poor physical fitness was associated with an increased risk of IBD. The association may be explained (in part) by prodromal disease activity reducing exercise capacity and therefore fitness. Low stress resilience was associated with an increased risk of receiving an IBD diagnosis. Stress may not be an important cause of IBD but may increase the likelihood of conversion from subclinical to symptomatic disease. PUD: Low stress resilience was associated with an increased risk of PUD. This may be explained by a combination of physiological and behavioural mechanisms that increase susceptibility to H. pylori infections and other risk factors. GI infections: Low stress resilience was associated with a reduced risk of GI infections, including enteric infections rather than the hypothesised increased risk.

The problem with which this study was concerned was that of developing a valid and reliable physical fitness test for college women which could be readily administered to large groups in a short period of time.

The problem of this study was to determine the effects of four dynamic exercise programs on physical fitness as measured by selected items from the American Association for Health, Physical Education, and Recreation Youth Fitness Test.

This study evaluated the effects of Project PACE, a program designed to increase physical activity, on the physical activity level and selected psychosocial variables of sedentary adolescent females ages 12 to 18. Psychosocial variables included self efficacy, attitude, perception of barriers, perceived social support, and knowledge. Of the 69 participants, 40 were enrolled in the treatment group and 29 were enrolled in the control group at the start of the study. The only significant differences were found for attitudes towards physical activity at base line. Findings from this study suggest that implementation of Project PACE protocol in school settings may produce some positive effects, but no significant findings were detected.

The purpose of the investigation was to determine the interrelationships of strength, speed, power and anthropometric measures in women. Sixty females ranging in ages from 18 to 25 volunteered as subjects. Subjects were measured for strength on the bench press, leg extension and leg curl, power vertical jump, speed--a 40 yard dash, body weight (BW) and fat weight (FW) using a scale and skinfold tests. The correlations for strength and power (.35 to .53), strength and speed (-.37 to -.56) and speed and power (-.45) were significant (p < .01). Partial correlations with (BW) and (FW) held constant were also significant, but were not significantly greater than their zero-order correlations.
