Download or read book The Effect of Mid flight Trunk Motion on Landing Mechanics written by Taylour J. Hinshaw and published by . This book was released on 2017 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: The anterior cruciate ligament (ACL) is a commonly experienced injury that can cause long-term negative health consequences. Previous research has observed increased trunk motion when ACL injuries occur during jump-landing tasks and suggest that trunk perturbation experienced while in the air may be a contributing factor to ACL injuries, however, the cause-effect relationship between trunk motion and ACL loading has not been established. The current researcher quantified the influences that both medial and lateral mid-flight trunk motions on landing biomechanics through center of mass analysis. Results from the current study showed that at initial contact, the upper body moved towards the reaching direction while the pelvis, ipsilateral leg, and contralateral leg moved in the opposite direction for the left and right reaching conditions when compared to the up condition. The ipsilateral leg moved closer to the overall COM and the contralateral leg moved further away, resulting in an asymmetric landing posture. The ipsilateral leg landed earlier for the left and right reaching conditions when compared to the up condition and also experienced a greater amount of vertical ground reaction force putting it at a higher risk for injury. Injury prevention programs should incorporate effective strategies to compensate for trunk motion experienced during the mid-flight of a jump.

Download or read book Advanced Strength and Conditioning written by Anthony Turner and published by Routledge. This book was released on 2022-02-15 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Becoming an effective strength and conditioning practitioner requires the development of a professional skills set and a thorough understanding of the scientific basis of best practice. Aimed at advanced students and novice-to-expert practitioners, in this book the authors explore the latest scientific evidence and apply it to exercise selection and programming choices across the full range of areas in strength and conditioning, from strength and power, speed and agility, to aerobic conditioning. Since the first edition of this text was written extensive research has expanded the supporting evidence base that provides the theoretical foundation for each chapter. In addition, some areas that were previously under-researched have now been expanded and some key concepts have been further challenged. Each chapter is written by experts with experience in a wide variety of sports, including both applied and research experience, ensuring this concise but sophisticated textbook is the perfect bridge from introductory study to effective professional practice. While advanced concepts are explored within the book, the coach must not forget that consistency in the application of the basic principles of strength and conditioning is the foundation of athletic development. Advanced Strength and Conditioning: An Evidence- based Approach is a valuable resource for all advanced students and practitioners of strength and conditioning and fitness training.

Download or read book Biomechanical Performance and Relevant Mechanism of Physical Medicine and Rehabilitation for Neuromusculoskeletal Disorders written by Qipeng Song and published by Frontiers Media SA. This book was released on 2023-11-23 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomechanical performance is a key to evaluating effectiveness in physical medicine and rehabilitation for neuromusculoskeletal disorders. Assessments can be applied to degenerative dysfunction (e.g., falls or knee osteoarthritis in older adults) and sports-related injuries (e.g., ankle sprain or anterior cruciate ligament injury). Patients' body movements and daily activity functions can be compared to the state of pre-injury condition or to the level of healthy individuals. Some cutting-edge studies have gone a step further and used biomechanical performance to develop physical medicine and rehabilitation approaches and explore the mechanisms behind their effectiveness. However, such studies are still relatively rare. This research topic is intended to encourage more relevant projects to be published. This research topic aims to encourage researchers to use biomechanical performance to design advanced physical medicine and rehabilitation approaches, evaluate the effectiveness of the rehabilitation approaches, and explore the mechanisms by which rehabilitation approaches work for neuromusculoskeletal disorders. Some studies have developed stretching approaches for the rehabilitation of knee osteoarthritis in older adults by measuring biomechanical performance during functional activities. Some studies indicated that the mechanism of physical activity to reduce falls in older adults lies in its effectiveness in increasing proprioceptive sensitivity, and further indicated that rehabilitation of proprioception may be a key to reducing falls in the fall-prone older adult population. Some other studies analyzed biomechanical performance in ankle ligament injuries to understand when, how, and why ligaments fail. As a result, this research topic will expand the application of biomechanical performance to better understand and treat neuromusculoskeletal disorders.
