Book Description
"Whole body vibration (WBV) is a mode of exercise by which an individual stands on a vibration platform that may be oscillating and therefore creating vertical displacement which affects gravitational forces acting upon the whole body. Manipulations of platform amplitude or frequency can affect the rate of change of the WBV (i.e. acceleration) acting upon an individual. The specific influences of frequency or amplitude, however, are unknown. The aim of the study, therefore, was two fold; (1) to identify chronic WBV effects of neuromuscular performance within a community dwelling older adult sample, and; (2) to identify WBV methods that would elicit chronic neuromuscular performance changes within such a sample. The study incorporated a randomised controlled experimental design to examine the aim. Seventy-three community dwelling older adults freely consented to the requirements of the study (mean age = 72.0 years). Neuromuscular performance was quantified with the 5-Chair Stands test, the Timed Up and Go (TUG) test and the Tinetti test. Health Related Quality of Life (HRQOL) was qualified with the SF-36 Health Survey. A six week WBV intervention significantly changed the quantifiers of neuromuscular performance in a community dwelling older adult sample. The WBV intervention significantly reduced time taken to complete the 5-Chair Stands test (p

Book Description
There were four major purposes of this study.The first was to evaluate a novel scale for the descriptive measure of everyday task performance in older adults [The strategy of difficulty continuum scale (SDCS)].The second and third were to explore the efficacy of resistance (RT), functional (FT) or resistance and functional (FRT) training for the improvement of neuromuscular function and everyday task ability in low functioning older adults, respectively.The final purpose was to evaluate attitudes of strength exercise in the community dwelling older adults. The results from this project provides useful information about a scale to measure functional performance, adaptability of the aging neuromuscular system, appropriate exercise training protocols for the pre-clinically disabled older adult and the current knowledge of beliefs of strength exercise in the community.

Book Description
Neuromechanics of Human Movement, Fifth Edition, draws on the disciplines of neurophysiology and physics to explore how the nervous system controls the actions of muscles to produce human motion. This contemporary approach is much different from the traditional approach, which focuses solely on mechanics and does not consider the role of the sensorimotor system in the control of human movement. Authored by Roger Enoka, a widely recognized and esteemed scholar in neuromechanics, this influential text is an essential resource in biomechanics, motor learning, and applied physiology, making complex information accessible to students. With material based on updated research in the field, this fifth edition provides a scientific foundation to the study of human movement, and as such it uses precise terms and definitions when discussing ideas. An appendix showcases both the base and derived units of the metric system as well as other learning tools, including a glossary of terms and a comprehensive list of the equations presented throughout the text. The text includes 70 practical learning examples, giving students the opportunity to work through a variety of problems and explore current research and applications. Content is visually reinforced with 341 figures, including specific illustrations of the neuromechanics involved in sport and rehabilitation movements. References have been streamlined and moved to the end of each chapter to improve readability. And instructors will benefit from an image bank that includes most of the figures and tables from the text to use in course materials. Significant content updates in the fifth edition present information relevant for both research and clinical environments, including more contemporary examples throughout the text and a new chapter on movement analysis. The following are additional key changes: • New figures that highlight and clarify key points • New information on energy costs • Debunking the concept of motor unit types • Detailed information on the center of mass trajectory • Explanation of neuromodulation • Additional content on PET imaging to help examine activity intensity To encourage a comprehensive learning experience, this updated edition follows a logical progression where each part builds on the material from the previous section. It begins with an introduction to the biomechanical terms and concepts commonly used to describe movement, focusing on the relation between force and motion. Part II deals with the motor system and introduces essential concepts from neurophysiology required for understanding how movement is produced by the nervous system. Part III focuses on adaptability of the motor system, including the acute and chronic changes that can occur in response to deviations in an individual’s level of physical activity. The fifth edition of Neuromechanics of Human Movement provides a scientific basis for the study of human movement while continuing to expand current knowledge in the fields of biomechanics and neurophysiology. By integrating these fields in a unique framework, this text offers professionals and students both valuable clinical information and inspiration to deepen their study of human movement.

Book Description
Recently, changes in human performance following whole-body vibration (WBV) training have been attributed to enhanced neuromuscular function. However, the exact neural and muscular mechanisms responsible for these changes remain less understood. The purpose of this study was to evaluate the acute and chronic effects of whole body vibration on the neural control of movement and muscle performance. Twenty male and female subjects with no history of leg injury were randomly assigned to either an experimental or control group. To assess the acute effects of WBV, data was collected from subjects immediately before and following an exposure to WBV (3 bouts of 2 minute with one minute rest between bouts). During the vibration exposure, subjects stood quietly on the platform with a slight amount of knee flexion. Subjects in the control group performed trials of quiet standing on the laboratory floor. Trial length, rest periods and body positions were identical for both groups. The variables used to evaluate the acute effects were electromechanical delay and rate of force development. To assess the chronic effects, the experimental group received WBV training in the laboratory over the course of 4 weeks. The training consisted of 3 sessions per week. During each session, the subjects performed 3 standing trials (2 minutes with one minute rest between bouts). The control group also reported to the laboratory for training consisting of trials of quiet standing. EMD and RFD were also used to assess chronic changes as well as two other measures on neural control, specifically presynaptic inhibition. The two measures of presynaptic inhibition were extrinsic presynaptic inhibition (EPI) and intrinsic presynaptic inhibition measured by paired reflex depression (PRD). The analysis for an acute effect consisted of a 2x2 (Group x Test) ANOVA for the dependent measures EMD and RFD. The experimental (WBV) group demonstrated a significant group x test interaction for the electromechanical delay (p=0.02) and rate of force development (p=0.03). The experimental group decreased EMD by 16% (from 23.42 ms to 19.3 ms) and increased RFD by 15.6% (from 274N/sec to 323 N/sec). The analysis for the chronic effect consisted of 2x3x2 (Group x Test x Time) repeated measure ANOVAs for the dependent measures (EMD, RFD, EPI, and PRD). After a 4 week of WBV training, the experimental (WBV) group demonstrated a significant decrease in electromechanical delay (EMD). The results also showed a significant group x test interaction for the rate of force development (RFD), and paired reflex depression (PRD) over the course of the study. There were no changes in extrinsic presynaptic inhibition noted in any of the comparisons. Through the use of these techniques and procedures, it is concluded that acute WBV has an effect on the EMD and RFD of the soleus muscle in young healthy subjects. Regarding chronic effects of WBV, our findings suggest that 4 weeks of WBV affects intrinsic presynaptic inhibition as measured by paired reflex depression as well as well as EMD and RFD.

Book Description
Over the past several decades, technological advances in computers, transportation devices, and other automated devices have decreased the need for human locomotion and physical activity in the workplace and at home. The need to be physically active in order to sustain and prosper in life has been almost fully eliminated by these technological advances. As a result, sedentary patterns of living have become more prevalent throughout all socioeconomic levels. Age related injuries and conditions including falls and osteoporosis can be debilitating or life ending and have been associated with sedentary behaviors as these can lead to decreased range of motion, muscular atrophy, impaired balance and motor control, reduced gait stability and speed, lower bone density, and subsequent falls. However, muscle weakness, dysfunction, and immobility do not have to consume an individual because the implementation of proper exercise interventions throughout the lifespan can delay or prevent age related injuries.Unfortunately, once a body has entered a state of detraining and lowered function it is often very difficult to reestablish neuromuscular control and bone density by using traditional exercise movements. The types of movements that will densify bones and replace degenerating muscle tissues are often very aggressive and require extensive equipment and supervision. Therefore, there is a need for a therapeutic intervention that can reinvigorate and reestablish neuromuscular control and bone density with little effort. The focus of the following studies is to investigate how the use of whole-body vibration as an exercise modality can improve physical function, as the study findings suggest this method of movement could be a solution to atrophy,weakness, and poor balance.Chapter 2 of this work presents a review of literature on whole-body vibration published in the Practical Pain Management journal. It addresses the current literature on a myriad of factors including pain, flexibility, bone density, balance, strength, and pulmonary rehabilitation.This review presents the findings of 65 studies, all which incorporate the use of a whole-body vibration platform on different populations, all possessing the common goal of assessing the body's response to vibration. Every condition studied in the review showed improvement,including pulmonary conditions like chronic obstructive pulmonary disease. This review of literature established and enhanced the author's curiosity and drive to perform additional studies using whole-body vibration as an exercise modality.Study 1 (Chapter 3) investigates the use of whole-body vibration on an active population with an average age of 53 years old and a max age of 69 years old. The subjects recruited were recreationally active golfers who did not partake it any specific fitness regimen or strength training program. The assessments administered to the study participants were chosen to reflect physical characteristics needed for golfing; however, these variables are also important in tracking and determining age related physical function. Subjects were tested for power using a kneeling medicine ball explosive chest pass, dynamic balance using the Y-Balance TestTM, core muscle endurance using the timed plank, and contralateral movement efficiency using a kineticstool called Fusionetics®. The study participants were separated into 3 groups, one which performed 4 simple body weight movements while standing on the whole-body vibration platform (VIB), one which completed the same movements while standing on stable group (GRD), and a control group who was asked to maintain their current regimen and not add additional exercise in (CON). There were significant improvements for VIB group (p
