This book was released on 2012-12-10 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical fitness affects our ability to function and be active. At poor levels, it is associated with such health outcomes as diabetes and cardiovascular disease. Physical fitness testing in American youth was established on a large scale in the 1950s with an early focus on performance-related fitness that gradually gave way to an emphasis on health-related fitness. Using appropriately selected measures to collected fitness data in youth will advance our understanding of how fitness among youth translates into better health. In Fitness Measures and Health Outcomes in Youth, the IOM assesses the relationship between youth fitness test items and health outcomes, recommends the best fitness test items, provides guidance for interpreting fitness scores, and provides an agenda for needed research. The report concludes that selected cardiorespiratory endurance, musculoskeletal fitness, and body composition measures should be in fitness surveys and in schools. Collecting fitness data nationally and in schools helps with setting and achieving fitness goals and priorities for public health at an individual and national level.

Download or read book The Influence of Receiving Real time Visual Feedback on Breathing During Treadmill Running to Exhaustion written by Joseph Andrew Passafiume and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The body has various physiological responses to any form of exercise, which include an increase in ventilation, oxygen uptake, and heart rate as work-load increases. The body relies on breathing to fuel the working muscles with oxygen during exercise, and this fuel ultimately allows the exercise being performed to continue. Respiratory inductance plethysmography (RIP) is a method of monitoring breathing through the placement of elastic belts around the chest and abdomen, and through this method it is known that the most efficient breathing entails the chest and abdomen expanding and contracting at the same time. This research therefore sought to examine if providing runners with real-time visual feedback on the breathing pattern of the chest and abdomen during a run could improve time to exhaustion. 13 recreational runners (8 females, 5 males) were put through a treadmill fatigue protocol to voluntary exhaustion on two separate days. The testing days followed the same procedures with the one difference being whether visual feedback was provided during the treadmill fatigue protocol. Visual feedback on the chest and abdomen were provided through animations created in LabVIEW, with each animation being independently controlled via the method of RIP. Phase angle was calculated as an average over each running interval of interest. A phase angle closer to zero degrees signifies more efficient and synchronous movement of the chest and abdomen during breathing. Time to exhaustion was not significantly improved when visual feedback was provided (p = 1). Phase angle had a negative correlation with visual feedback (r = -0.089) but was not significant (p = 0.667). Six participants had an improved phase angle when visual feedback was provided, and in turn four of the participants had an improved time to exhaustion. Furthermore, three of these six participants improved phase angle by a value of 9 degrees or better, and all three of these participants improved time to exhaustion. These results suggest that receiving visual feedback and altering breathing pattern to a more efficient method could take more familiarization than originally assumed. Although the overall trend between time to exhaustion and phase angle was not shown to be significant across the entire group, sub-analysis of the participants that improved phase angle with visual feedback suggests the possibility that ultimately improving phase angle could lead to an improved time to exhaustion. Future work should focus on familiarizing all participants with any type of breathing technique or visual feedback prior to running to ensure that phase angle has a better chance of being improved.

Available in PDF, EPUB and Kindle. Book excerpt: The field of lifestyle medicine, which is the study of how daily habits and actions impact on both short- and long-term health and quality of life, continues to expand globally. The scientific and medical literature that supports the success of these lifestyle habits and actions is now overwhelming. Thousands of studies provide evidence that regular physical activity, maintenance of a health body weight, following sound nutritional practices, stress reduction, and other good practices all profoundly impact both health and quality of life. Following its predecessors, Lifestyle Medicine, Third Edition, is edited by lifestyle medicine pioneer, cardiologist Dr. James Rippe. This edition has been thoroughly updated and represents the expert opinions of 20 section editors as well as more than 150 expert chapter authors whose knowledge span all aspects of this emerging discipline. Topics cover lifestyle medicine practices including regular physical activity, proper nutrition, and weight management. These principles are applied to the prevention and or treatment of a wide variety of chronic conditions ranging from heart disease and diabetes to cancer, mental health, addiction, and injury prevention. This book serves as evidence base for individuals who wish to practice lifestyle medicine or incorporate some of its principles into either general medicine or subspecialty practice. It provides valuable information to healthcare workers in the fields of nutrition, exercise physiology, psychology, behavioral medicine, health promotion, and public policy where lifestyle medicine principles play an ever-increasing role.
Download or read book Physiological Responses at the Rating of Perceived Exertion at and Above the Gas Exchange Threshold During Treadmill Running written by Kristen C. Cochrane and published by . This book was released on 2016 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purposes of this study were to examine: 1) the metabolic, cardiovascular, respiratory, neuromuscular, and velocity responses during continuous, constant rating of .perceived exertion (RPE) runs at the RPE corresponding to the velocity at the gas exchange threshold (RPEGET) and 15% above GET (RPE GET+15%); and 2) the metabolic efficiency changes during continuous, constant RPE runs at RPEGET and RPEGET+15%. Eleven moderately trained runners performed an incremental treadmill test to exhaustion. GET and GET+15% were determined from the incremental test to exhaustion, and the velocity at GET and GET+15% were used to estimate the RPEGET and RPEGET+15% using linear regression. On separate days, subjects performed 60 min runs at RPEGET and RPEGET+15%, and physiological, neuromuscular, and perceptual responses were recorded. Polynomial regression analyses were used to examine the patterns of responses for all of the variables and paired-samples t-tests were used to determine changes in metabolic efficiency at RPEGET and RPEGET+15%. The results of the polynomial regression analyses indicated that there were negative, quadratic relationships (R2 = 0.96 -- 0.99) for V˙ O2, RER, V˙ E, and velocity vs. time at RPEGET and RPEGET+15%; positive, quadratic relationships (R2 = 0.87 and 0.74) for Fb vs. time at RPEGET and RPEGET+15%; and positive, linear (r2 = 0.73), and no significant (r2 = 0.0) relationships for HR vs. time at RPEGET and RPEGET+15%, respectively. There were negative, linear relationships (r2 = 0.96 and 0.63) for VL and VM EMG RMS vs. time, and positive, linear relationships (r 2 = 0.72 and 0.40) for VL and VM EMG MPF vs. time at RPEGET. In addition, there was a negative, linear relationship (r2 = 0.16) for VL EMG RMS vs. time, a positive, quadratic relationship (R2 = 0.74) for VM EMG RMS vs. time, and positive, quadratic relationships (R 2 = 0.73 and 0.96) for VL and VM EMG MPF vs. time at RPEGET+15% . There were decreases in metabolic efficiency at RPEGET and RPEGET+15%. These findings indicated that the only variable that tracked RPE was the normalized, composite HR vs. time response at RPE GET+15%, and that treadmill running at RPEGET and RPE GET+15% was sustainable for up to 60 min.
Download or read book Physiological Responses at the Critical Heart Rate During Treadmill Running written by Haley C. Bergstrom and published by . This book was released on 2014 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purposes of this study were to: 1) determine if the critical heart rate (CHR) model for cycle ergometry can be applied to treadmill running; and 2) examine the times to exhaustion (Tlim) as well as the VO2, ratings of perceived exertion (RPE), electromyographic amplitude (EMG AMP) and mean power frequency (MPF) responses during constant heart rate (HR) runs at CHR-5 b˙min-1 (CHR-5), CHR, and CHR+5 b˙min-1 (CHR+5). Thirteen runners performed an incremental treadmill test to exhaustion. On separate days, 4 constant velocity runs to exhaustion were performed. The total number of heart beats (HBlim) for each velocity was calculated as the product of the average 5 s HR and Tlim. The CHR was the slope coefficient of the HBlim versus Tlim relationship. The physiological responses were recorded during the constant HR runs. Polynomial regression analyses were used to examine the patterns of responses for all. The HBlim versus Tlim relationship (r2 = 0.995 - 1.000) was described by the linear equation: HBlim = a + CHR (Tlim). The CHR-5 (mean +/- SD = 171 +/- 8 b˙min-1, 88 +/- 3% HRpeak), CHR (175 +/- 8 b 8 b˙min-1 , 91 +/- 3% HRpeak), and CHR+5 (178 +/- 6 b˙min -1, 94 +/- 3% HRpeak) were maintained for 56.97 +/- 1.23, 48.37 +/- 11.04, and 20.11 +/- 16.08 min, respectively. There was no change in HR, quadratic decreases in velocity and VO 2, and quadratic or linear increase in RPE during continuous runs at a constant HR. At CHR-5, EMG AMP decreased and EMG MPF increased. There was an increase in EMG AMP and no change in EMG MPF at CHR, while there was no change in EMG AMP and EMG MPF decreased at CHR+5. These findings indicated the CHR model for cycle ergometry was applicable to treadmill running, and, on average, HR values that were less than or equal to the CHR, represented sustainable (30 to 60 min) intensities, while CHR+5 did not.
