The purpose of this study was to determine the validity of the Ebbeling one-stage submaximal treadmill protocol to estimate maximal oxygen uptake in overweight males and females. Forty-five male and females (36.5±10.9 years; 170.2±9.9 cm; 77.9±9.0 kg) were categorized into overweight groups using a BMI of 25-29.9 kg/m2. The subjects performed a submaximal protocol that consisted of one 4-minute stage with individualized speeds of 2.0-4.5 mph at 5% grade and subsequently performed a maximal exercise test. There were significant relationships between observed and estimated VO2max for males (r=.796), females (r=.426), and gender combined (r=.844). There was an underestimation in the estimation of VO2max in the present study when comparing males (10%), females (26%) and gender combined (17%) subjects. The results indicated that a body mass index between the values of 25-29.9 kg/m2 did create a difference in estimating VO2max in the present study when comparing that to Ebbeling et al.

The purpose of this project was to determine the effects of 6 g of ground cinnamon added to farina (Cream of Wheat) cereal on blood glucose levels between obese and normal weight individuals. Thirty students, aged 19-30 years, were recruited to participate in this study. During study visits, participants were given one of two test meals (74 g of farina with and without 6 g of cinnamon) followed by seven blood glucose measurements over a two-hour period. A significant difference was seen in glycemic response between the two dietary conditions, but not between the two BMI groups (normal and obese). The two BMI groups were combined for analysis of dietary conditions. Ingestion of the cinnamon cereal resulted in significantly lower blood glucose responses at minutes 15, 30, 45 and 60 compared to the plain cereal. The results of this study confirm the positive glucose-lowering effects of cinnamon. / Department of Family and Consumer Sciences
