The Effects Of Overfeeding On Body Composition: The Role Of Macronutrient Composition - A Narrative Review, Alex Leaf, Jose Antonio

International Journal of Exercise Science

International Journal of Exercise Science 10(8): 1275-1296, 2017. Compared to investigations on hypocaloric diets, the effects of chronic overfeeding have been less studied. It has been posited that consuming calories in excess of daily caloric requirements will result in a gain in body weight and in particular fat mass regardless of which macronutrient(s) are consumed. However, recent evidence suggests that there is a quantitative difference in protein versus carbohydrate and/or fat overfeeding as it relates to body composition. Protein overfeeding or the consumption of a high protein diet may not result in a gain in body weight ...

Head And Neck Embryology: An Overview Of Development, Growth And Defect In The Human Fetus, Allison Baylis

Honors Scholar Theses

The purpose of this research is to explore the growth and formation of the head and neck from embryological development through puberty in order to understand how this knowledge is necessary for the development of dental and medical treatments and procedures. This is a necessary aspect of the medical and dental school curriculum at the University of Connecticut Health Center Schools of Medicine and Dental Medicine that needs to be incorporated into the current study of embryology for first-year students. Working with Dr. Christine Niekrash, D.M.D, this paper will cover the embryology and growth of the head, face ...

Comparison Of The Ymca Cycle Sub-Maximal Vo2 Max Test To A Treadmill Vo2 Max Test, Jeremy G. Carter, Kelly A. Brooks, Joshua R. Sparks

International Journal of Exercise Science: Conference Proceedings

INTRODUCTION: An individual’s maximum capacity to extract, transport, and utilize oxygen is reflected by their VO2 max (10,22). Numerous physiological factors affect a person’s maximal oxygen consumption. A person’s VO2 max is dependent on their pulmonary, cardiovascular, and muscular systems, which depends on their ventilation-aeration efficiency, central and peripheral blood flow, and metabolism of their active muscles (13,17). The six factors that have the most influence on a person’s maximal aerobic power are heredity, state of training, gender, body size and composition, age, and the mode of the exercise (16). A person’s VO2 ...

Vo2 Reserve Vs. Heart Rate Reserve During Moderate Intensity Treadmill Exercise, Tanner J. Solheim, Brad G. Keller, Charles J. Fountaine

International Journal of Exercise Science

International Journal of Exercise Science 7(4) : 311-317, 2014. ­VO₂ and heart rate (HR) are widely used when determining appropriate training intensities for clinical, healthy, and athletic populations. It has been shown that if the % reserve (%R) is used, rather than % of max, HR and VO₂ can be used interchangeably to accurately prescribe exercise intensities. Thus, heart rate reserve (HRR) can be prescribed if VO₂ reserve (VO₂R) is known. Therefore, the purpose of this study was to compare VO₂ R and HRR during moderate intensity exercise (50%R). Physically active college students performed a ...

Human Anatomy And Physiology Preparatory Course, Carlos Liachovitzky

Open Educational Resources

The overall purpose of this preparatory course textbook is to help students familiarize with some terms and some basic concepts they will find later in the Human Anatomy and Physiology I course.

The organization and functioning of the human organism generally is discussed in terms of different levels of increasing complexity, from the smallest building blocks to the entire body. This Anatomy and Physiology preparatory course covers the foundations on the chemical level, and a basic introduction to cellular level, organ level, and organ system levels. There is also an introduction to homeostasis at the beginning.

Accuracy Of The Omron Hbf-500 Body Composition Monitor In Male And Female College Students, Michael I. Pribyl, John D. Smith, G Richard Grimes

International Journal of Exercise Science

The Omron HBF-500 is an inexpensive body composition monitor that incorporates both hand-to-hand and foot-to-foot electrical impedance technology. At this time, studies examining the accuracy of the HBF-500 when estimating percent body fat (%BF) are scarce and if this instrument gains popularity due to its claimed precision, comparisons against validated techniques should be conducted. The purpose of this study was to assess the accuracy of the Omron HBF-500 body composition monitor using the BOD POD as a criterion. Forty-eight men and 33 women participated in the study (24.3±6.9 years, 171.0±10.0 cm, 78.4±18 ...

The Effect Of Cold On The Physiology Of Drosophila Larva Heart And On Synaptic Transmission At Crayfish Neuromuscular Junctions, Yuechen Zhu

Theses and Dissertations--Biology

Ectothermic animals are susceptible to temperature changes such as cold shock with seasons. To survive through a cold shock, ectotherms have developed unique strategies. My interest is focusing on the physiological function of during cold shock and prolonged cold exposure in the fruit fly (Drosophila melanogaster) and crayfish (Procambarus clarkii). I used Drosophila melanogaster as a model system to investigate cardiac function in response to modulators (serotonin, acetylcholine, octopamine, dopamine and a cocktail of modulators) in acute cold shock and chronic cold shock conditions as possible mechanism to regulate heart rate in the cold. To examine if the dampened heart ...

The Validity Of 7-Site Skinfold Measurements Taken By Exercise Science Students, Tiago V. Barreira, Matthew S. Renfrow, Wayland Tseh, Minsoo Kang

International Journal of Exercise Science

International Journal of Exercise Science 6(1) : 20-28, 2013. Skinfold (SKF) measurement is arguably the most ubiquitous method of estimating percent body fat (%BF) because of cost, ease, and feasibility. However, it is unknown how accurately novice exercise science students measure SKF thickness. Thus, the purpose of this study was to determine the validity with which exercise science students in an Exercise Physiology course measured skinfold thickness and estimated percent body fat (%BF) when compared to a skilled technician. Twenty-three novice undergraduate students were afforded both verbal measurement instruction and visual measurement demonstration and, subsequently, assessed SKF thicknesses of a ...
