The purpose of this investigation is to determine if the provision of a protein and carbohydrate beverage during and/or after endurance exercise affords improved performance in a subsequent bout of exercise compared to carbohydrate alone. The secondary purpose of this project will be to evaluate if the addition of protein enhances fluid retention, thereby minimizing the effects of dehydration and consequently improving exercise performance.
This research study was developed and is currently in implementation under the guidance of Dr. Byrne and Dr. Mattern with the assistance of five undergraduate exercise physiology students. These students enrolled in an independent study course to participate in this research project.
This study is being supported by Infinite Nutrition.
There is evidence that Social Cognitive Theory (SCT) based interventions may be successful in increasing physical activity among college students. The study sought to determine if a SCT course based, peer education fitness training intervention could enhance physical activity. The objective of the study was to determine if a peer fitness training intervention was effective at increasing: 1) physical activity levels, 2) fitness, and 3) academic achievement of the participants.
This study was the result of an interdepartmental collaboration with Dr. Jennifer Boyle from the Department of Health Science. Study implementation was achieved by having exercise physiology students conduct a variety of physiological assessments at the beginning of the semester on 45 students enrolled in HLS 301: Principles of Healthy Living. Each of the exercise physiology students was then matched with three HLS 301 students who serve as their “clients” for the course of the semester. At the end of the semester the exercise physiology students performed post assessments on their clients such that they could observe physiological changes.

The purpose of this study was to determine how raisins influence the postprandial serum glucose and insulin responses in 3 separate groups of people: 1) a healthy, young adults, non-athletic group, 2) a group of young adult competitive endurance athletes, and 3) a group of persons with impaired fasting glucose.
Dr. Byrne and Dr. Mattern collaborated with the Ohio State University and Rochester Clinical Research to execute this study. Undergraduate exercise physiology students were able to assist with data collection. Two of the students developed a research poster which was presented at the Annual Meeting of the American College of Sports Medicine.

The purpose of the study was to determine if raisins, when eaten as a pre-exercise food for people with impaired fasting glucose, will result in more stable blood glucose and insulin levels during low intensity aerobic exercise compared with a glucose solution or an energy bar providing the same amount of carbohydrate.
