This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: Running related injuries occur between 20-25.9% per 1000 running exposure hours (1-5). Many factors contribute to this risk including experience, training habits, biomechanics, running surface, and elevation changes. Stress fractures are a common injury in track athletes and distance runners (6) and are associated with increased loading rates (7), which have been observed in downhill running (DHR)(8). Benefits accompanying incline training include improved maximal speed, stride rate (SR) and decreased contact time (9). DHR has shown to improve agility and change-of-direction ability (10) but has been linked to increased low back pain from bending and twisting related to muscle and lumbar region strains (11,12). However, trunk motion and gait characteristics have not been assessed beyond -15% grade in DHR. The purpose of this study was to examine experienced runners' trunk motion and gait characteristics at different speeds and DHR grades. Methods: Seven participants (21±1.91 years; 167.44±6.56 cm, 62.07±11.49 kg) completed randomized running trials at various speeds and grades (3.0, 3.5, 4.0 m/s; 0, -7, -14, -21% grade). Discussion: The present study revealed significant changes occurred at the steepest grade: increased SR, vertical ground reaction forces, and decreased stride length (SL). At the slowest speed, SL increased while SR decreased up to - 14% grade but increased at -21% while SL decreased. However, at the fastest speed, SR and SL decreased between -14 and -21% grade. This suggests changes in running mechanisms at different speeds and steeper grades than compared to level ground and shallow grades. Gait modifications at steep grades are likely to keep the center of gravity above the base of support. Observed zGRFs increases may lead to an increased injury risk, specifically at steeper grades.

Book excerpt: Reviews of The Science of Running:"The Science of Running sets the new standard for training theory and physiological data. Every veteran and beginner distance coach needs to have this on their book shelf."-Alan WebbAmerican Record Holder-Mile 3:46.91 "For anyone serious about running, The Science of Running offers the latest information and research for optimizing not only your understanding of training but also your performance. If you want to delve deeper into the world of running and training, this book is for you. You will never look at running the same."-Jackie Areson, 15th at the 2013 World Championships in the 5k. 15:12 5,000m best If you are looking for how to finish your first 5k, this book isn't for you. The Science of Running is written for those of us looking to maximize our performance, get as close to our limits as possible, and more than anything find out how good we can be, or how good our athletes can be. In The Science of Running, elite coach and exercise physiologist Steve Magness integrates the latest research with the training processes of the world's best runners, to deliver an in depth look at how to maximize your performance. It is a unique book that conquers both the scientific and practical points of running in two different sections. The first is aimed at identifying what limits running performance from a scientific standpoint. You will take a tour through the inside of the body, learning what causes fatigue, how we produce energy to run, and how the brain functions to hold you back from super-human performance. In section two, we turn to the practical application of this information and focus on the process of training to achieve your goals. You will learn how to develop training plans and to look at training in a completely different way. The Science of Running does not hold back information and is sure to challenge you to become a better athlete, coach, or exercise scientist in covering such topics as:· What is fatigue? The latest research on looking at fatigue from a brain centered view.· Why VO2max is the most overrated and misunderstood concept in both the lab and on the track· Why "zone" training leads to suboptimal performance.· How to properly individualize training for your own unique physiology.· How to look at the training process in a unique way in terms of stimulus and adaptation.· Full sample training programs from 800m to the marathon.

Download or read book Muscle Recovery After Exercise Training and Competition Physiological Indicators and Non invasive Monitoring Techniques written by Alessandro Moura Zagatto and published by Frontiers Media SA. This book was released on 2020-05-21 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The desire to improve muscle function and prevent overuse injuries from exercise and throughout training has led to the development of various methods to aid recovery and track readiness to perform. Ergogenic aids such as cold-water immersion, massage, and dynamic recovery procedures may have positive effects but the results of the related research remain equivocal. Furthermore, novel interventions in this scenario, like compression garments, ice vests, and photobiomodulation therapy are promising but need more evidence-based data to support their effectiveness. Similarly, to properly monitor individual physical conditioning, there is a growing interest toward unobtrusive measures to accurately represent physiological status during and/or after exercise. There are several techniques being used, such as subjective ratings of well-being, heart rate monitoring, hormonal and hematological profile assessments. However, more sensitive indexes like heart rate variability and muscle activation (voluntary and/or involuntary) are arising as attractive alternatives that may delineate physical conditioning status and readiness to perform more precisely than the aforementioned measures. The purpose of this Research Topic is to critically evaluate and summarize recent data from observational and intervention studies related to non-invasive methods designed to promote recovery and objectively monitor training status. Their association to physical performance and physiological recovery in athletes during training and competition is a major focus of this Topic.

Available in PDF, EPUB and Kindle. Book excerpt: Four samples of 5 consecutive tibial impact shock magnitudes (TIS) of each limb were collected at each running grade condition using piezoelectric accelerometers. Symmetry indices (SI) were calculated using TIS for left and right limbs from a previously established equation. The results indicate that measured SI was not significantly influenced by decreasing running grade conditions for all subjects. Also, there were no significant differences between preference groups across running grade conditions. A trend suggested differences between training groups across grade conditions, and analysis of covariance for stride length and step frequency indicated a significant difference between downhill trained and untrained subjects (p

Recent studies have shown that up to 85% of runners get injured every year, how natural is that? The most important question that running "barefoot" or "naturally" doesn't address is how we should run. Repetitive ground impact forces are at the root of most running injuries. A 30 minute jog can log more than 5,000 foot strikes; its because of this volume of movement that efficient

Available in PDF, EPUB and Kindle. Book excerpt: The popularity of high-intensity interval training (HIIT), which consists primarily of repeated bursts of high-intensity exercise, continues to soar because its effectiveness and efficiency have been proven in use by both elite athletes and general fitness enthusiasts. Surprisingly, few resources have attempted to explain both the science behind the HIIT movement and its sport-specific application to athlete training. That’s why Science and Application of High-Intensity Interval Training is a must-have resource for sport coaches, strength and conditioning professionals, personal trainers, and exercise physiologists, as well as for researchers and sport scientists who study high-intensity interval training.
