This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predicted maximal aerobic capacity (VO2max), using submaximal exercise tests, is used to evaluate fitness for job performance, especially within the military. Women who use oral contraceptives experience a rhythmic variation of circulating synthetic hormones that can influence submaximal exercising heart rate. The purpose of this study was to examine the validity and reliability of two submaximal heart rate-dependent cycle ergometry exercise tests, one used by the Air Force (AF) and one suggested by the American College of Sports Medicine (ACSM), for women using oral contraceptives. Eighteen healthy and fairly active women, aged 19-22 years, completed a maximal treadmill exercise test with indirect calorimetric determination of VO2max followed two days later by submaximal testing. Each of the three tests were conducted in both the quasi-luteal (Q-L) phase (the second week of the active pill) and the quasi-follicular (Q- F) phase (the last 3 days of placebo administration). VO2max was lower (by 1.1 + 0.63 ml/kg/min) in Q-L than in Q-F (Q-L = 38.2+ 1.1 ml/kg/min, Q-F = 39.3 1 1.1 ml/kg/min, P = 0.055). Comparison of VO2max predicted by the AF test to the true maximal value revealed a slight, statistically non-significant (1.5%) overestimation in the Q-L phase (AF = 38.8 1 1.8 ml/kg/min vs Max = 38.2 1 1.1 ml/kg/min, P = 0.3) and a larger underestimation (5%) in the Q-F phase (AF = 37.41 1.8 ml/kg/min vs Max = 39.3 11.1 ml/kg/min, P = 0.06). Between the two phases, the predicted values of the AF test were significantly different (Q-L = 38.8 1 1.8 ml/kg/min, Q-F = 37.4 1 1.8 ml/kg/min, P = 0.02). The ACSM test underestimated VO2max in the Q-L (3%) phase and significantly.

Book excerpt: Phase 1A: Twenty-five healthy males, 18 to 30 years of age, completed this study to cross-validate the Banister-Legge (B-L) submaximal cycle ergometry test. The B-L nomogram for untrained and trained subjects and the USAF CE significantly underestimated the measured VO2 sub max. The B-L nomogram was not recommended as a protocol for use by the USAF. Phase 1B: Fifty-eight males and 61 females, 18 to 48 years of age, completed this study to develop new submaximal cycle ergometer protocols and prediction equations to estimate VO2 sub max. Ramp (registered) and ramp to steady-state (RSS) protocols, six prediction equations for men, and three prediction equations for women were developed. Phase 2: Thirty-one males and 36 females, 18 to 40 years of age, completed this study comparing the 1-mile walk and USAF CE test for estimating VO2 sub max. There were no significant differences between the VO2 sub max estimated by these tests and the measured VO2 sub max A subset of this population (17 males and 20 females) also completed R and RSS tests. There were no significant differences between the measured and estimated VO2 sub max for the 1-mile walk, the USAF CE, the six new equations for men, and one of three new equations for women.

Download or read book Validity of Submaximal Cycle Ergometry for Estimating Aerobic Capacity written by and published by . This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The accepted method for determining maximal oxygen consumption is collection and analysis of expired gases which has been limited to the research laboratory. Although a variety of tests may be more practical, the relative safety, validity, and reliability has been a concern. To simplify the Wahlund/Astrand-Rhyming protocols to enhance test precision as well as making it reasonable for the non-technically trained test administrator, a procedure has been developed that allows early selection of the most appropriate test work load. A computerized version makes it possible for non-trained personnel to safely administer this test for estimating aerobic capacity. This study critically evaluates the relationship between estimates of maximal oxygen consumption by a specific cycle ergometer protocol and (1) values obtained by the criterion method employing indirect calorimetry and exhaustive treadmill exercise, and (2) the very high and very low levels of aerobic capacity that are implicit for competitive endurance athletes and for documented sedentary adults, respectively.

Additional chapters present the current evidence on circadian endocrine physiology, exercise in older adults, exercise and hormone regulation in weight control, and the effects of overtraining in sports. Chapters brand new to this edition present the role of hormones in muscle hypertrophy, the effect of exercise on hormones in metabolic syndrome patients, how exercise impacts appetite-regulating hormones in clinical populations, and the relative energy deficiency in sport (RED-S) condition.

Download or read book Endocrinology of Physical Activity and Sport written by Naama Constantini and published by Springer Science & Business Media. This book was released on 2013-03-13 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the influence and interaction between physical activity and the endocrine system are of paramount importance in dealing with a multitude of health problems. In Endocrinology of Physical Activity and Sport, renowned physicians and researchers provide a comprehensive and expanded update on the scientific, clinical and practical components of endocrinology as related to sport and exercise. The authors thoroughly review what is known about how such activity effects the endocrine system and how in turn these hormonal responses affect many other organs and systems of the body. In addition, aspects of endocrinology in non-glandular tissue which have endocrine actions are addressed; for example, adipocytes and the release of leptin and related adipocytokines. Further, a wide range of clinically related topics such as athletic amenorrhea, osteopenia, sarcopenia, and hypogonadism are included. This new edition critically integrates what is known about the complex interaction of the endocrine system in the sports context and will again prove immensely valuable to all physicians and clinical investigators treating those active in sports today.

This book was released on 2005-06-18 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dietary Reference Intakes for Water, Potassium, Sodium, Chloride, and Sulfate The Dietary Reference Intakes (DRIs) are quantitative estimates of nutrient intakes to be used for planning and assessing diets for healthy people. This new report, the sixth in a series of reports presenting dietary reference values for the intakes of nutrients by Americans and Canadians, establishes nutrient recommendations on water, potassium, and salt for health maintenance and the reduction of chronic disease risk. Dietary Reference Intakes for Water, Potassium, Sodium, Chloride, and Sulfate discusses in detail the role of water, potassium, salt, chloride, and sulfate in human physiology and health. The major findings in this book include the establishment of Adequate Intakes for total water (drinking water, beverages, and food), potassium, sodium, and chloride and the establishment of Tolerable Upper Intake levels for sodium and chloride. The book makes research recommendations for information needed to advance the understanding of human requirements for water and electrolytes, as well as adverse effects associated with the intake of excessive amounts of water, sodium, chloride, potassium, and sulfate. This book will be an invaluable reference for nutritionists, nutrition researchers, and food manufacturers.
