Hawks and published by . This book was released on 2014 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of the different estrogen and progesterone concentrations during different menstrual cycle phases on recovery after exercise have been studied minimally, with contradicting results. Therefore, the purpose of this investigation was to study the effects of the menstrual cycle on EPOC and lactate concentration during recovery from maximal exercise in physically active women. Regularly exercising eumenorrheic women (n=4) participated in this study by completing two testing days: one during the mid-follicular phase, and the other during the mid-luteal phase. A three day meal plan consisting of 1.5 g protein·kg body mass -1 ·d-1 , 30% of total kcal from lipid, and remaining kcal from carbohydrate was followed before each of the test days. On each test day, blood draws for phase confirmation and a maximal oxygen consumption (VO2max ) test to volitional exhaustion were completed. At minutes 0, 3, 6, 10 and 20 of recovery, blood lactate concentration was measured and excess post-exercise oxygen consumption (EPOC) analyzed throughout. There was no statistical significance (p

This book was released on 2012 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are several different physiological differences between males and females that can affect exercise performance. Particularly, women experience the menstrual cycle when variations of estrogen and progesterone occur every 23-38 days. This fluctuation of hormones can have many physiological effects on the body. While estrogen helps decrease cholesterol levels, increase fat metabolism, and promote bone health, progesterone acts by increasing ventilatory drive. Oral contraceptive pills regulate the hormone fluctuations of the menstrual cycle and provide a more physiological stable environment for users. Although women play and compete at all phases of their menstrual cycle, the specific phase may have an impact on their sports performance. This study was designed to determine the effects of menstrual cycle phase and oral contraceptive use on aerobic and anaerobic exercise performance. Subjects were 7 female varsity student-athletes at Central Connecticut State University who were currently taking a 28 day cycle oral contraceptive pill. They completed a VO2 max treadmill test and anaerobic bike test at the follicular phase and luteal phase of one menstrual cycle. The follicular phase was defined as when the subject was taking her inactive birth control pill and the luteal phase was defined as when she was taking her active pill. Results found that there was no difference in VO2 max, final heart rate, RER, or blood lactate accumulation between phases during the aerobic running to exhaustion test. There was also no difference in peak power, work, mean power, and fatigue index between phases during an anaerobic bike test. However, there was a difference in final blood lactate accumulations in anaerobic exercise, with values being higher during the follicular phase. It is suggested there was no change in exercise performance because highly trained athletes have already adapted to the physiological changes caused by the fluctuations of hormones. Any perceived differences in performance could be due to psychological factors of performing when menstruating. More research should be done explaining the effects of the menstrual cycle and oral contraceptives on exercise performance, specifically with highly trained athletes.

This book was released on 1992 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The researcher examined the potential differences in lactate threshold, blood lactate concentrations, run time to exhaustion, and cardiorespiratory indices between menstrual cycle phases of eumenorrheic distance runners (25.1 Z 3.52 yrs). Testing was done in the early follicular phase (FP) , 2-4 days after the onset of bleeding and the mid-luteal phase (LP) , 6-8 days after ovulation. Ovulation was determined by a 0.3°C increase in basal body temperature. During each phase, the subjects performed a maximal effort test during which lactate threshold (LT) , peak lactate (peak . HLA), VO2 Max, and maximal heart rate (Max HR) were measured (N = 8), and an 85% submaximal run to voluntary exhaustion test during which blood lactate concentrations (HLA) , VO2 Ve, RER, RPE, end RPE, HR, and run time to exhaustion (RTE) were measured (N = 7). No significant differences (p > .05) were found between phases ln HLA, LT, Peak HLA, RER, RPE, Ve, VO2 VO2 Max, Max HR, HR, RER, and RTE. These results suggest that menstrual cycle phase has no effect on metabolic responses, cardiorespiratory responses, or performance parameters of eumenorrheic distance runners.

Available in PDF, EPUB and Kindle. Book excerpt: "In this fifth edition of Principles of Exercise Testing and Interpretation, as in earlier editions, we attempt to develop conceptual advances in the physiology and pathophysiology of exercise, particularly as related to the practice of medicine. The underlying theme of the book continues to be the recognition that the most important requirement for exercise performance is transport of oxygen to support the bioenergetic processes in the muscle cells (including, of course, the heart) and elimination of the carbon dioxide formed as a byproduct of exercise metabolism. Thus, appropriate cardiovascular and ven- tilatory responses are required to match those of muscle respiration in meeting the energy demands of exercise. As depicted by the logo on the book cover, normal exercise performance requires an efficient coupling of external to internal (cellular) respiration. Appropriate treatment of exercise intolerance requires that patients' symptoms be thought of in terms of a gas exchange defect between the cell and the environment. The defect may be in the lungs, heart, peripheral or pulmonary circulations, the muscles themselves, or there may be a combination of defects. Thus, we describe the pathophysiology in gas transport and exchange that affect any site in the cardio- respiratory coupling between the lungs and the muscles. We illustrate how cardiopulmonary exercise testing can provide the means for a critical evaluation by the clinician-scientist of the functional competency of each component in the coupling of cellular to external respiration, including the cardiovascular system. To achieve this, clinical cases are used to illustrate the wide spectrum of pathophysiology capable of causing exercise intolerance"--Provided by publisher.

Available in PDF, EPUB and Kindle. Book excerpt: As sports have become more competitive over recent years researchers and trainers have been searching for new and innovative ways of improving performance. Ironically, an area as mundane as what an athlete eats can have profound effects on fitness, health and ultimately, performance in competition. Sports have also gained widespread acceptance in the therapeutic management of athletes with disorders associated with nutritional status. In addition, exercise has been one of the tools used for studying the control of metabolism, creating a wealth of scientific information that needs to be placed in the context of sports medicine and science. Nutrition in Sport provides an exhaustive review of the biochemistry and physiology of eating. The text is divided into three sections and commences with a discussion of the essential elements of diet, including sections on carbohydrates, proteins, fats, vitamins and trace elements, and drugs associated with nutrition. It also discusses athletes requiring special consideration, including vegetarians and diabetics. The second section considers the practical aspects of sports nutrition and discusses weight control (essential for sports with weight categories and athletes with eating disorders), the travelling athlete (where travel either disrupts established feeding patterns or introduces new hazards), environmental aspects of nutrition (including altitude and heat), and the role of sports nutritional products.

Available in PDF, EPUB and Kindle. Book excerpt: Alphaherpesviruses are a fascinating group of DNA viruses that includes important human pathogens such as herpes simplex virus type 1 (HSV-1), HSV-2, and varicella-zoster virus (VZV): the causative agents of cold sores, genital ulcerous disease, and chickenpox/shingles, respectively. A key attribute of these viruses is their ability to establish lifelong latent infection in the peripheral nervous system of the host. Such persistence requires subversion of the host's immune system and intrinsic antiviral defense mechanisms. Understanding the mechanisms of the immune evasion and what triggers viral reactivation is a major challenge for today's researchers. This has prompted enormous research efforts into understanding the molecular and cellular biology of these viruses. This up-to-date and comprehensive volume aims to distill the most important research in this area providing a timely overview of the field. Topics covered include: transcriptional regulation, DNA replication, translational control, virus entry and capsid assembly, the role of microRNAs in infection and oncolytic vectors for cancer therapy. In addition there is coverage of virus-host interactions, including apoptosis, subversion of host protein quality control and DNA damage response pathways, autophagy, establishment and reactivation from latency, interferon responses, immunity and vaccine development. Essential reading for everyone working with alphaherpesviruses and of interest to all virologists working on latent infections.
