The purpose of the study was to examine the relationship between treadmill time, maximal oxygen consumption and pace characteristics of the 1.5 and 3 mile runs and to compare the distances and pace characteristics as predictors of aerobic capacity. Subjects were 70 college aged males, ages 18 to 25, enrolled in jogging and conditioning classes at North Texas State University. Three tests were administered: the 1.5 mile run, the 3 mile run and the Bruce treadmill test. The data were analyzed using correlations and factor analysis. Conclusions of the investigation were (1) the 1.5 and 3 mile runs are valid measures of aerobic capacity, (2) the 3 mile run does not significantly increase the correlation between VO2max and endurance runs and (3) pacing characteristics are evident in the 1.5 and 3 mile runs.

A research report submitted to the Faculty of Health Sciences, University of the Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the degree Of Master of Family Medicine Johannesburg, July 2014 / BACKGROUND Physical activity has been consistently shown to play an important role in healthy ageing. While motivators and barriers to regular physical activities among old people residing in old age homes have been studied in other parts of the world, the researcher found no studies on this subject in South Africa. Therefore, the aim of this research was to identify the motivators and barriers to regular exercise in elderly people residing in old age homes in Ekurhuleni Southern sub-district of Gauteng province. METHODS This was a descriptive cross sectional study conducted among elderly residents in old age homes in Ekurhuleni Southern Sub-district. A structured questionnaire was administered in the common languages: English, Afrikaans and Zulu. The data was collected by the researcher (assisted by research assistants) from 139 residents in seven old age homes. A Pearson chi square test was used to examine the relationship between participants’ characteristics with regular exercise. RESULTS This study showed that having knowledge of exercise benefits (P-value= 0.001) an opportunity to socialize (P-value= 0.001) was statistically associated with regular exercise. Similarly, younger age (P- value= 0.02), high educational attainment (P-value= 0.03), being of white race (P -value= 0.04) were the main motivators to regular exercise. In contrast, poor health (P-value=0.001) and lack of knowledge of exercise benefits (P-value=0.001) were the major barriers to regular exercise. CONCLUSION Increasing residents’ knowledge of the benefits of regular exercise, opportunity for socialization and providing support to elderly people are crucial in increasing the uptake and maintenance of regular exercise among elderly people living in old age homes in Ekurhuleni Southern Sub-district.

The U.S. Department of Health and Human Services has made the promotion of regular physical activity a national health objective, and experts believe that physical education can play a significant role in the promotion of physical activity. Feasible measurement tools to assess physical activity behavior, by physical educators, are lacking. One validated instrument is the System for Observing Fitness Instruction Time (SOFIT; McKenzie, Sallis & Nader, 1991). SOFIT's physical activity data are collected using momentary time sampling (MTS) with a 20-second interval length and provide estimates of Moderate to Vigorous Physical Activity (MVPA). Whether variations in interval lengths would adversely affect the accuracy of the MVPA data has not been investigated. From a clinical perspective, if physical education teachers are to utilize MTS procedures for on-going assessment they will require longer time intervals to collect accurate MVPA data. Therefore, this project sought to determine the accuracy of MVPA levels collected through varying observation tactics (i.e., 20s, 60s, 90s, 120s, 180s, and random) relative to those collected through duration recording (DR). Video records of 30 randomly selected elementary school physical education classes were utilized for this study. Utilizing modified physical activity codes from SOFIT, the researchers collected MTS data regarding students' MVPA at varying interval lengths (i.e., 20s, 60, 90s, 120s, 180s, and random). Three statistical techniques, Pearson-product moment (PPM) correlation coefficients, Repeated Measures Analysis of Variance (RM ANOVA), and Average Error (AE), were utilized to demonstrate concurrent validity of the varying interval lengths. Results demonstrated moderate-low to high correlations between the 20s, 60s, 90s, and random interval lengths and the DR tactic during the total class. The RM ANOVA indicated similarity between all the varying interval lengths and the DR tactic for total class observation. The MTS procedure that created the least amount of AE across classes was the 20s variable followed by the 60s, random, and 90s variables. These findings build empirical evidence for the use of a 60s, random, and 90s MTS procedure for the purpose of MVPA assessment by physical educators. / Graduation date: 2004
