This book was released on 2010 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous research has shown that muscle activation patterns of the anterior thigh influence knee joint mechanics and in particular, patellar tracking. Vastus lateralis and vastus medialis muscles are located on the lateral and medial sides of the quadriceps group respectively. They are the primary muscles responsible for maintaining patellar tracking through the patellofemoral groove in order to prevent knee conditions such as patellofemoral pain syndrome. If either the vastus lateralis or vastus medialis muscle has a predominant level of activation, then the patellar will tend to be drawn to one side of the patellofemoral groove. Rehabilitation protocols for treating patellar maltracking and patellofemoral pain often focus on improving muscle activation of vastus medialis. Vastus medialis is the smallest anterior thigh muscle responsible for leg extension, with lower activation levels often resulting in the patellar being drawn laterally. Although rehabilitation protocols may focus on medial muscle activation, both muscles are innervated by the same nerve, suggesting that improved vastus medialis muscle activation will also result in improved vastus lateralis muscle activation. To combat this problem it has been suggested that turning the foot out to 45 degrees may improve vastus medialis activation due to the interaction of the adductor magnus muscle. Another theory suggests that vastus medialis will be in a relatively higher position than vastus lateralis when seated, and therefore, the muscle needs to work harder to oppose gravity. Three exercises (leg press, squat and terminal leg extension) were assessed in order to determine if commonly employed rehabilitation protocols can improve vastus medialis activation. The exercises were performed with two foot positions (parallel/vertical and turned out to 45 degrees) at 5 0 % of 3 R M and the resultant E M G activity was normalised to a series of isometric M V C trials. Single differential electrodes were placed on the muscle bellies of vastus medialis and vastus lateralis, running parallel to the muscle fibres, with an earth electrode over the patella. Synchronised E M G and video data were collected to allow for the assessment of muscle activation during seated and standing posture exercises, open and closed kinetic chain exercises and for both foot positions to determine if any of these exercise conditions would result in improved vastus medialis muscle activation. The results showed that any improved vastus medialis activation also coincided with improved vastus lateralis activation, with both muscles contracting to perform leg extension motion. Higher levels of muscle activation generally occurred when the foot was in a parallel/vertical foot position, and the squat exercise resulted in higher levels of muscle activation than both of the seated exercises. The two closed kinetic chain exercises also demonstrated higher levels of muscle activation when the leg was in a flexed position, while the open kinetic chain exercise produced higher levels of muscle activation as the leg moved toward an extended position.
Book Synopsis The Effects of Foot Angle and Leg Position on the Activation Levels of Vastus Medialis and Vastus Laterals by : Priya
Download or read book The Effects of Foot Angle and Leg Position on the Activation Levels of Vastus Medialis and Vastus Laterals written by Priya and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This study aimed to determine the influence of foot angle and leg position on the activation levels of vastus medialis (VM) and vastus lateralis (VL) muscles during two common leg extension exercises. Specifically, this study aimed to preferentially recruit VM by introducing a gentle stretch over the muscle, through the combination of thigh adduction and tibial external rotation (with the foot turned out to 45 degrees). Healthy and asymptomatic volunteers (N=29) performed two leg extension exercises, leg press and terminal leg extension, in two different foot positions (feet parallel/vertical, or foot turned out to 45 degrees) and with or without a component of thigh adduction achieved by placing a firm ball between the knees of the subject. Subjects included were participants of team sports. Outcome measures included: Peak EMG activation for VM and VL during the leg extension phase, normalised to MVC; Average EMG activation for VM and VL during the leg extension phase, normalised to MVC; and Knee flexion angle at the time of peak VM and VL activation. Data for each condition were compared using a three factor repeated measures ANOVA. Trends in the data revealed a tendency toward higher muscle activation during the closed kinetic chain exercise (leg press) compared to an open kinetic chain exercise (terminal leg extension). These peak activation values also occurred with the leg in a more flexed position during the leg press compared to the terminal leg extension exercise. However, it was also observed that turning the foot out to 45 degrees does not greatly influence muscle activation in a preferred direction. Furthermore, introducing a gentle stretch over the muscle by adding components of thigh adduction and leg external rotation (with the ball in place) was found to be ineffective in selectively activating VM under these experimental conditions. On the basis of these findings and within the limitations of this research, it was concluded that whilst dynamic quadriceps contractions are undertaken, altered limb or foot position towards tibial external rotation and hip adduction has no influence on preferential activation of VM in asymptomatic individuals.

Book Synopsis Biomechanics of Cycling by : Rodrigo R. Bini
Download or read book Biomechanics of Cycling written by Rodrigo R. Bini and published by Springer Science & Business. This book was released on 2014-04-30 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bicycles have been a common device to enhance physical fitness level in gyms and training centers along with solid use in competitive sport. For that reason, biomechanics of cycling has grown as a research field with many publications addressing different perspective of the interaction between the cyclist and his bicycle. The most common end point of research on biomechanics of cycling is optimization of performance and reduction of injury risk. One goal of this book is to meet the growing need for a comprehensive presentation of contemporary knowledge on biomechanics of cycling which will positively influence the activity of cycling in a global fashion. In order to accomplish this purpose, ten chapters are presented with focus on varying methods for biomechanical analysis of cycling motion. The introduction section provides an overview of the main methods for assessment of cycling motion, including motion analysis, pedal force measurements, muscle activation, anthropometry and joint kinetics. These methods are discussed in depth in individual chapters followed by chapters on characteristics of bicycles and potential perspectives to improve their configuration in order to improve performance of cyclists and reduce their overuse injury risk. Moreover, a preliminary method to train technique in cyclists is shown. A final chapter provides authors perspective on the upcoming technology that should be effective in helping training of cyclists.
