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.

Download or read book Recovery stress Questionnaire for Athletes written by Michael Kellmann and published by Human Kinetics. This book was released on 2001 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provides athletic specialists, trainers, and coaches with resources for monitoring athletes to avoid over-training, burnout, and decreased performance. The questionnaire is based on the hypothesis that an accumulation of stress in different areas of life, with insufficient opportunity for recovery, leads to a compromised psychophysical state. Stress states are based on 12 nonspecific and seven sports-specific scales. The questionnaire package offers tools to measure and track an athlete's recovery, including two complete questionnaires (72- and 56-item forms), manual scoring keys, profile sheets, and a user manual that describes questionnaire development and data and profile interpretation.c.

Download or read book High Intensity Exercise in Hypoxia Beneficial Aspects and Potential Drawbacks written by Olivier Girard and published by Frontiers Media SA. This book was released on 2018-01-25 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past, ‘traditional’ moderate-intensity continuous training (60-75% peak heart rate) was the type of physical activity most frequently recommended for both athletes and clinical populations (cf. American College of Sports Medicine guidelines). However, growing evidence indicates that high-intensity interval training (80-100% peak heart rate) could actually be associated with larger cardiorespiratory fitness and metabolic function benefits and, thereby, physical performance gains for athletes. Similarly, recent data in obese and hypertensive individuals indicate that various mechanisms – further improvement in endothelial function, reductions in sympathetic neural activity, or in arterial stiffness – might be involved in the larger cardiovascular protective effects associated with training at high exercise intensities. Concerning hypoxic training, similar trends have been observed from ‘traditional’ prolonged altitude sojourns (‘Live High Train High’ or ‘Live High Train Low’), which result in increased hemoglobin mass and blood carrying capacity. Recent innovative ‘Live Low Train High’ methods (‘Resistance Training in Hypoxia’ or ‘Repeated Sprint Training in Hypoxia’) have resulted in peripheral adaptations, such as hypertrophy or delay in muscle fatigue. Other interventions inducing peripheral hypoxia, such as vascular occlusion during endurance/resistance training or remote ischemic preconditioning (i.e. succession of ischemia/reperfusion episodes), have been proposed as methods for improving subsequent exercise performance or altitude tolerance (e.g. reduced severity of acute-mountain sickness symptoms). Postulated mechanisms behind these metabolic, neuro-humoral, hemodynamics, and systemic adaptations include stimulation of nitric oxide synthase, increase in anti-oxidant enzymes, and down-regulation of pro-inflammatory cytokines, although the amount of evidence is not yet significant enough. Improved O2 delivery/utilization conferred by hypoxic training interventions might also be effective in preventing and treating cardiovascular diseases, as well as contributing to improve exercise tolerance and health status of patients. For example, in obese subjects, combining exercise with hypoxic exposure enhances the negative energy balance, which further reduces weight and improves cardio-metabolic health. In hypertensive patients, the larger lowering of blood pressure through the endothelial nitric oxide synthase pathway and the associated compensatory vasodilation is taken to reflect the superiority of exercising in hypoxia compared to normoxia. A hypoxic stimulus, in addition to exercise at high vs. moderate intensity, has the potential to further ameliorate various aspects of the vascular function, as observed in healthy populations. This may have clinical implications for the reduction of cardiovascular risks. Key open questions are therefore of interest for patients suffering from chronic vascular or cellular hypoxia (e.g. work-rest or ischemia/reperfusion intermittent pattern; exercise intensity; hypoxic severity and exposure duration; type of hypoxia (normobaric vs. hypobaric); health risks; magnitude and maintenance of the benefits). Outside any potential beneficial effects of exercising in O2-deprived environments, there may also be long-term adverse consequences of chronic intermittent severe hypoxia. Sleep apnea syndrome, for instance, leads to oxidative stress and the production of reactive oxygen species, and ultimately systemic inflammation. Postulated pathophysiological changes associated with intermittent hypoxic exposure include alteration in baroreflex activity, increase in pulmonary arterial pressure and hematocrit, changes in heart structure and function, and an alteration in endothelial-dependent vasodilation in cerebral and muscular arteries. There is a need to explore the combination of exercising in hypoxia and association of hypertension, developmental defects, neuro-pathological and neuro-cognitive deficits, enhanced susceptibility to oxidative injury, and possibly increased myocardial and cerebral infarction in individuals sensitive to hypoxic stress. The aim of this Research Topic is to shed more light on the transcriptional, vascular, hemodynamics, neuro-humoral, and systemic consequences of training at high intensities under various hypoxic conditions.
Download or read book Pacing in Sport and Exercise written by Andrew Edwards and published by Nova Science Publishers. This book was released on 2014-07 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pacing in sport and exercise: a psychophysiological perspective is the first book which comprehensively examines the way humans pace exercise and sporting activities. This concept represents an exciting opportunity to combine the latest physiological and psychological theories with practical sport and exercise applications. The book will be an essential read for sport and exercise science academics, students, coaches, athletes and general exercise enthusiasts. Pacing is the strategy by which effort is managed across an exercise bout in relation to a specific goal and in the knowledge of the likely demands of the task. It is widely recognised that individuals distribute effort across a task and this is in evidence during all non-reflex exercise situations where individuals are able to receive and act upon neural feedback from peripheral physiologic systems. As such, pacing across a wide range of sport and exercise contexts is investigated and explained. Sporting activities as diverse as sprinting, soccer, triathlon, rowing and cycling are discussed. In addition, training methodologies to improve the ability to self-pace exercise are reviewed and a self-regulatory system to optimise training across all exercise types is proposed. Templates for consolidating training sessions, design and monitoring strategies are included. Pacing in relation to specific population groups such as children, overweight/obese individuals and those with chronic or acute illnesses is also discussed. Finally, it is hoped this new book will stimulate further research, growth and awareness of this important topic.

Download or read book High Altitude Physiology and Medicine written by W. Brendel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: High altitude physiology and medicine has again become important. The excep tional achievements of mountaineers who have climbed nearly all peaks over 8,000 m without breathing equipment raise the question of maximal adaptation ca pacity of man to low oxygen pressures. More importantly, the increase in tourism in the Andes and the Himalayas brings over 10,000 people to sites at altitudes above 4,000 and 5,000 m each year. At such heights several kinds of high alti tude diseases are likely to occur, and these complications require detailed medical investigations. Medical authorities need to inform both mountaineers and tourists as to how great a physical burden can be taken in the mountain environment without risk to health. Physicians need to know what kind of prophylaxis is to be employed at high altitudes to prevent the development of diseases and what therapeutic measures should be used once high altitude diseases have occurred. Moreover, the physical condition of the indigenous population living at higher altitudes such as the Andes and the Himalayas, who are exposed continuously to the stress of high altitude, requires our attention. We have become familiar with symptoms characteristic of chronic high-altitude disease: under special conditions this popu lation has a tendency to develop pulmonary hypertension, which is associated with pulmonary edema, pulmonary congestion, and right heart failure.

Available in PDF, EPUB and Kindle. Book excerpt: Renowned running coach Budd Coates presents Runner's World Running on Air, a revolutionary yet simple training method based on rhythmic breathing to help runners at all experience levels improve their performance, prevent injury, and experience the joy of running. Validating his method through a mix of accessible science, Eastern philosophy, and the experiences of test subjects, Coates shows readers how focusing on their breathing brings their minds and bodies into harmony and helps them run stronger, faster, and more comfortably. Rhythmic breathing increases lung volume; improves awareness and control; helps prevent injury and side stitches; improves running for those with asthma; allows runners to quickly set a pace for quality training and racing; and helps athletes manage muscle cramps. This book reviews the basics of rhythmic breathing, teaching readers how to perform it while walking and, eventually, while running. Weeklong sample schedules from different programs shows readers how to apply the rhythmic breathing scale to any workout. Coates also touches on the importance of stretching, cross-training, and core training and provides detailed training plans and schedules.
