Metabolic Rate Lab Report

Introduction: In this experiment, cardiovascular fitness is being determined by measuring how long it takes for the test subjects' to return to their resting heart rate. Cardiovascular fitness is the ability to "transport and use oxygen while exercising" (Dale 2015). Cardiovascular fitness utilizes the "heart, lungs, muscles, and blood working together" while exercising (Dale 2015). It is also how well your body can last during moderate to high intensity cardio for long periods of time (Waehner 2016). The hypothesis is that people who exercise for three or more days will return to their resting heart rate much faster than people who only exercise for less than three days.

Freeman (2008) furthers Eckert et al’s argument by stating that the actin filaments of the muscle cell in organisms are able to intake ATP (adenosine triphosphate) faster and will move the organism faster when higher temperatures are imposed. This is because of an increase in enzyme reaction rates (Freeman 2008). These arguments can be applied to our experiment to help explain the trends observed. It can be argued that as the Gammarus setosus experiences the cold treatments, the organ of Bellonci senses the cold temperature, which in turn signals the organism to preserve its energy to protect itself; therefore, the organism will swim slower. In addition, the enzymes in the muscle cells of the organism, when experiencing the cold treatments, will have decreased ability to carry out enzymatic reactions, therefore inhibiting the uptake of ATP, which will cause the organism to swim slowly. Conversely, as the organisms are put into the heated treatments, the organ of Bellonci senses the heat, and allows the organism to swim faster, since it does not have allocate as much of its energy towards survival. Furthermore, the enzymes in the cells will be able to catalyze reactions more quickly, therefore allowing the organism to swim faster. However, when the temperature of the surroundings is too high, the enzymes will denature, therefore, reducing the activity rate of

direct calorimetry. Furthermore, the amount of oxygen in the chamber reveals the amount of cellular respiration of the organism. While also, test the effects of decreasing oxygen, and later increasing the heat on the metabolic rate of goldfish. I hypothesize that an increase in temperature will increase their metabolic rate

In this lab, we are going to try to answer the question, Does body size affect endotherms metabolic rates? This question is very controversial among scientists. They’ve only agreed on one thing, there are different scalings between animals, but they don 't know how that affects metabolism and why (Hoppler and Weibel 2005). Some scientist’s studies show that body size in endotherms does affect metabolism rate due to SA/V ratios. The ratios affect the endotherms metabolism based on how high or low the SA/V ratio is. An animal with a larger SA/V ratio puts off more heat to their environment. This results in smaller animals having to burn through their food more to maintain their body temperature (“Unit 4 Demos More on Metabolic Rate”). What led us to the formation of our experiment was the experiment performed in the article Smith et al. (2015). In

Introduction: Exercise is a physical activity or particular movement that is used in order to become healthier and stronger. (1) Exercise, in all of its forms, has various effects on the different systems in the human body. One of the main benefits is cardiovascular health, including circulation and heart health. Exercise uses a lot of energy, which the cells derive from oxidising glucose. Meaning that the heart has to work harder to pump more blood throughout the body and the heart has to beat faster in order to achieve a high effort. (2) The heart benefits from exercise include being able to pump more blood through the body and continue working at a higher level with less strain. (3)

The ad claims that Zyladex plus promotes weight loss. The ad states that " As much as 4 inches and 50% of all excess fat gone in just 14 days!" This ad expresses the fast and efficient weight loss in a little amount of time. So many americans have problems with their weight. They try many methods to getting their bodies as fit as possible. People would do anything to lose weight and this ad lures many desperate consumers into buying their product.

Metabolic syndrome is a group of disorders that predisposes to the cardiovascular disorders and constituted a significant risk for coronary heart disease, however, its effect on gene expression pattern is unclear. The considerable evidence demonstrated that genetic factors predispose to the cardiovascular complications. Metabolic syndrome significantly alters cardiac gene expression profile which may be involved in the development of cardiovascular disease.

Dr Tebi is hands-down one of the best medical doctors I have seen in a long time and I am 63 years old! Being a Type I diabetic for 60 years and a Senior Systems Engineer, I do my homework before placing my health and well being into someone's hands. Even more so now that many healthcare professionals are medical groups that rely on spending very little time with patients to meet quotas. Dr Tebi's bed-side manner is calm, positive, thorough, attentive, flexible, and personal. My visit was for a diabetic checkup where he went through each item on the lab report with detailed explanations so that I knew exactly how my diabetic control was. During his review of your health he makes you feel very comfortable and relaxed allowing me to easily

For this experiment we strived to answer whether or not the type of exercise affects heart rate? We predicted that heart rate will increase slower when a human test subject is doing sit ups compared to burpee’s. Our null hypothesis stated that the heart rate will not change when a human test subject is doing sit ups compared to burpees. We conclude with all our data that Burpees increase heart rate faster than sit ups do, and that the type of exercise does affect your heart rate. The slope of the burpee best fit line was clearly higher than the sit up one.

Living things release energy by a process called respiration. When aerobic respiration occurs, sugar and oxygen are converted into energy, water and carbon dioxide, which is a waste product that is released into the atmosphere by excretion.

The clinical significance of metabolic syndrome (MS) is well defined and described since the 1920’s. The general conditions defines MS, and are part of the equation to determine the results from the National Cholesterol Education Program Adult Treatment Panel (NCEP/ATP III) definition and from the Centers for Disease Control (Center for Disease Control and Prevention, 2013).

Introduction The objectives of lab 9 were to introduce us to the techniques available to assess body composition, practice using these techniques to estimate body composition and to understand the differences in their techniques and their advantages and disadvantages. Methods First we measured BMI, or body mass index. To calculate your BMI you take you weight (kg) divided by height (m) squared. Although this test is not a good way to track changes in body composition, it has important implications for relation body composition to health outcomes.

Predictors of insulin resistance (IR) usually suffer from poor sensitivity and high specificity when applied to populations other than the original one, thereby limiting their diagnostic usefulness. In order to better define the optimal cut-off values of several biochemical predictors of insulin resistance we studied a cohort of non-diabetic subjects in whom we obtained a direct measurement of insulin resistance and, additionally, performed an OGTT and also, measured triglycerides to calculate several predictors of insulin resistance.

this experiment, five Homo sapiens will be used as subject for the experiment. Exposure to extreme temperature, (below 2 0 degrees Celsius) causes increase in metabolic reaction 2 . High water temperatures, conversely, cause the stimulation of heat

The influence of CO2 depends on CO2 concentration, time of exposure, type and stage of maturity of the product (Fonseca et al., 2002). Elevated levels of CO2 cause reduction in respiration rate, however, concentrations of 20% CO2 leads to significant increase in anaerobic respiration (i.e. ethanol and acetaldehyde production), and irreversibly damages the tissues. Similar to decreased O2 level, increased CO2 concentration also inhibits the decarboxylation reactions of normal respiratory process causing it to shift to the anaerobic pathway (Kader and Saltveit, 2002. Variable patterns of respiration were observed among different commodities. Pal and Buescher (1993) reported decrease in respiration rate at 10% CO2 and increase at 30% CO2. The idea of respiratory inhibition by CO2 was first supported by simple explanations, i.e., that CO2 was a product of the respiration process and, caused simple feedback inhibition (Herner, 1987; Wolfe, 1980).
