This book was released on 2014 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Author's abstract: It is important for elite endurance athletes to have practical and reliable means of measuring fatigue throughout their training. Variations in Autonomic Nervous System activity (ANS) may provide an effective marker of fatigue and of recovery. ANS control of heart rate is well known to be affected by exercise training, and those adaptations can be determined using measures of heart rate variability (HRV). Previous research has examined the effect of training on HRV and ANS control of heart rate in males, there is a lack of any comprehensive studies that address adaptations in female athletes. Therefore, the purpose of this study was to investigate the changes in HRV and ANS fluctuations in female swimmer athletes throughout an entire collegiate swim season. 9 Division I female swimmers (Age: 20.6±1.01) were used to determine HRV at three different points in their competitive training: pre-season, mid-season, and post-season. During each testing session, HRV was measured both at rest and during a maximal 400 yd freestyle swim. Heart rate values were determined using Polar heart rate monitors, and the HRV analyses was conducted using Kubios 2.0 HRV analysis software. Global ANS balance was shown to significantly shift towards Sympathetic (SNS) predominance during the mid-season testing and significantly shift towards parasympathetic (PNS) predominance during post-season testing. HRV analysis appears to be an appropriate tool to monitor the effects of physical training loads on performance and fitness in female athletes, and it can be used to help identify and prevent overtraining states.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Heart rate variability (HRV) measurements vary depending on a person's body position. The purpose of this study was to compare the postural effects on HRV between Division III swimmers and Division III runners. This was an experimental and cross-section study. Division III swimmers and cross-country runners (N = 29), ages 18 to 22 years old, participated in an orthostatic stressor while HRV measurements were taken after 10 minutes of laying down, immediately standing, and after 10 minutes of continued standing. Three separate 2x3 mixed factorial ANOVAs were used for heart rate (HR), low frequency to high frequency (LF/HF) ratio, and high frequency (HF) measurements, to compare the two types of athletes across the three time points. For both types of athletes HR significantly increased when comparing 10 minutes of supine to immediately standing (p

Download or read book The Influence of Sleep and Heart Rate Variability on the Occurrence of Injuries Illnesses and Missed Participation Days in NCAA Collegiate Swimmers written by Bruin Armwald and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Athlete populations are at an increased risk of suffering an injury or illness due to their high level of physical activity. Additionally, athletes may not attain adequate bodily recovery following their training and/or competition sessions. This is particularly true of collegiate athletes who balance the demands of their sport with academic responsibilities. Recent innovations in wearable technology have allowed researchers to track specific recovery metrics such as sleep and heart rate variability. This study utilized the WHOOP Performance Optimization System to measure sleep and heart rate variables in a group of 11 NCAA Division 1 swimmers (Males= 8, Females= 3) for the duration of their season. Data related to covariables including training load and body composition were also recorded. Outcomes of interest were injuries, illnesses, and missed participation days. Descriptive statistics as well as stepwise logistical regression were used to discern the influence of predictor variables on the occurrence of adverse health events. Ten athletes completed data collection and were used for analysis. Average total sleep time was 6.51 ( 0.23) hours, and average HRV was 78.08 ( 7.54) ms. Regression analysis identified total sleep as a significant predictor of illnesses (OR= 0.70, 95% CI= 0.55-0.89, P

Download or read book Fitness Measures and Health Outcomes in Youth written by Institute of Medicine and published by National Academies Press. 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 Effects of Endurance Training and Hydration on Baroreceptor Response and Orthostatic Tolerance in Athletes Vs Non athletes written by Kaitlin Dunn and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to assess the effects of hydration status on orthostatic vital signs and the baroreceptor response following an inversion table test in both endurance-trained individuals and sedentary individuals. The study consisted of two different groups of women: sedentary and aerobically fit. The sedentary group had five women who reported rarely exercising. The fit group consisted of five women who participate in endurance training, either running or swimming, at least three days a week. The independent variables were the degree of inversion and time between vital sign measurements. The dependent variables included the values for the individuals’ heart rate and blood pressure, as well as self-reported symptoms of syncope, during inversion. These values were measured at rest and every thirty seconds while inverted. During the first trial, the subjects fasted for at least three hours before two minutes of inversion. Immediately after the first trial, the subjects drank a 16 oz. bottle of water over a ten minute span. After hydration, the subjects completed another two minutes of inversion. It was hypothesized that the endurance-trained subjects would experience less change from baseline in heart rate and blood pressure than the sedentary individuals during both the hydrated and dehydrated trials. It was also hypothesized that heart rate and blood pressure of all subjects would change less during the hydrated trial than during the dehydrated trial. Self-reported symptoms were hypothesized to be more abundant in sedentary individuals than in endurance trained individuals across both trials. Data concluded that aerobically fit and hydrated individuals can regulate their heart rate and blood pressure more quickly than unfit and dehydrated individuals, but the differences in these values between the two groups were not significant (p>0.05). It was also concluded that sedentary and dehydrated individuals were more likely to experience symptoms of pre-syncope than endurance-trained and hydrated individuals.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers the essence of sports training, new concepts and technologies, the prerequisites and scope of an individualised approach to training as well as how to integrate the main methodological paradigms of sports training systems using the theory of adaptation. Modernisation and analysis of a body's potential plus features of efficient adaptation make it possible to adjust training loads and to ensure excellent sporting performances, particularly with the help of artificially controlled training environments. This book suggests the use of modern training methods in endurance sports. For example, it shows the benefits of focused application of exercises in developing local and regional muscular endurance, and provides recommendations on training for important competitions. It also describes the peculiarities of short-term reactions and the long-term adaptation of athletes to the techniques mentioned and to a higher level of performance.

This book was released on 2023-11-28 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exercise testing is a versatile tool for health purposes. When used in combination with specific devices and sensors, it can provide valuable diagnostic and prognostic information in a wide range of populations. Exercise testing outcomes are also useful for training prescriptions and defining responses to clinical trials evaluating interventions. Whole-body maximal tests (e.g., cardiopulmonary exercise testing), field tests (e.g., walking tests), and modalities isolating a muscle group (e.g., isokinetic endurance testing) all have their advantages and limits and should be viewed as complementary. Recent advances in wearable technology and artificial intelligence provide unique opportunities to broaden the application of these tests and facilitate their interpretation. In the meantime, the clinimetric properties of some widely used exercise tests are still poorly documented in several clinical populations, which hampers optimal diagnosis and management. Moreover, most exercise tests used in clinical practice are suffering from a lack of ecological validity and there is a need to develop and valid new testing modalities that best mimic daily life functioning. This Research Topic aims to extend our knowledge regarding the validity and clinical utility of various exercise testing modalities and facilitate their interpretation. This topic supports a multimodal approach to exercise testing and welcomes reports investigating either whole-body or local muscle testing. Submission of research combining different exercise modalities and investigating their potential links are particularly encouraged. Inter-disciplinary research with studies integrating concepts, tools, and data from various disciplines like exercise physiology, biomechanics, and psychology are of particular interest for this Research Topic. This topic is not restricted in terms of age, medical conditions, or type of disease but manuscripts must have clear implications for human health.

Download or read book Recovery and Stress in Sport written by Michael Kellmann and published by Routledge. This book was released on 2019-03-19 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: Balancing training, stress, and recovery is essential for achieving optimal performance. The performance of professional athletes can be severely compromised by overtraining, injuries, prolonged periods of competition, or even life events outside their sporting lives. The current recovery-stress state depends on preceding stress and recovery activities, but through simultaneous assessment of stress and recovery, a differentiated picture can be provided. This manual includes two measurement instruments to gauge individual recovery, enabling both athletes and coaches to better understand the often-unconscious processes that impinge upon peak performance, and to monitor the physical, mental, emotional, mental, and overall recovery-stress state before and after training. The Acute Recovery and Stress Scale (ARSS) and the Short Recovery and Stress Scale (SRSS) are instruments that systematically enlighten the recovery-stress states of athletes. Through utilization of the ARSS and the SRSS, athletes and coaches can better understand the importance of daily activities, including how they can relate to stress/recovery and the direct impact on athletic performance. In addition to the instruments themselves, both of which are simple and easy to use, the manual also discusses their development, their basis in theory, and case studies showcasing their usage. The ARSS and the SRSS provide important information regarding the current recovery-stress state during the process of training, and are essential tools for coaches, sport scientists, sport psychologists, and athletes alike.
