Book The Effect of Static Stretching and Order of Warm up on Isokinetic Peak Torque of the Knee Extensors

Download or read book The Effect of Static Stretching and Order of Warm up on Isokinetic Peak Torque of the Knee Extensors written by Eric J. Sobolewski and published by . This book was released on 2010 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purposes of these studies were to determine if an acute static stretch influenced isokinetic peak torque (IPT), and to examine if the order in which the warm up routine was performed affected peak knee extension torque. Twenty trained college male students performed maximal isokinetic knee extensions under four conditions: a control consisting of no stretching, a stretch only trial, jog then stretch, and stretch then jog conditions. Each stretch was held for a total volume of 360 s. Measurements were taken on a Biodex System 3 isokinetic dynamometer at speeds of 60° s−1 and 300° s−1. Data were analyzed using t-tests to compare the stretch condition with the control. The results indicated that there was a significant difference between the stretch and the control at 300° s−1 (p = 0.03 t = 2.42) but not at 60° s−1 (p = 0.16). A 2 x 3 ANOVA (300° s−1 x 60° s−1, and control x stretch then jog x jog then stretch) yielded no significance at either speed (p> 0.05). Conclusions from this study indicate that stretching should not be the sole exercise in a warm-up routine as previous research confirms the decrease in IPT after stretching. Another finding of this study is that the negative effects of stretching can be diminished when combined with an aerobic activity such as jogging prior to performance. Further research is needed to determine the underlying factors that contribute to the post stretch decrease in IPT and the factors that lead to the restoration of force after aerobic activity. Caution is advised since these were controlled tests in a laboratory and results may vary with actual performance.

Book Acute Effects of Antagonist Stretching on Jump Height and Knee Extension Peak Torque

Download or read book Acute Effects of Antagonist Stretching on Jump Height and Knee Extension Peak Torque written by John B. Sandberg and published by . This book was released on 2011 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: A great deal of research has shown decrements in force and power following static stretching. There has been little research investigating the acute effects of static stretching of the antagonist on the expression of strength and power. The purpose of this study was to investigate the effects of static stretching of the antagonist muscles on a variety of strength and power measures. Sixteen active males were tested for vertical jump height and isokinetic torque production in a slow knee extension (KES) at 60 [degrees]/s and a fast knee extension (KEF) at 300 [degrees]/s. Electromyography was taken during knee extension tests for the vastus lateralis and the biceps femoris muscles. Participants performed these tests in a randomized counterbalanced order with and without prior antagonist stretching. All variables for stretching and non-stretching treatments were compared using paired t tests at an alpha of .05. Paired samples t tests revealed a significant (p = .034) difference between stretch KEF and non-stretch KEF conditions. There was no significant (p> .05) difference between KES stretch and non-stretch conditions. Vertical jump height was significantly (p = .011) higher for the stretching treatment than the non-stretching treatment. Vertical jump power was also significantly higher (p = .005) in the stretch versus the non-stretch condition. Paired samples t test indicated no significant (p> .05) difference between testing conditions for electromyography, represented as a percentage of maximal voluntary contraction (MVC). These results suggest that stretching the antagonist hamstrings prior to high speed isokinetic knee extension increases torque production. It also demonstrated that stretching the hip flexors and dorsi flexors may enhance jump height and power. Practitioners may use this information to acutely enhance strength and power performances.

Book The Efficacy of Warm up and Stretching on Lower Extremity Muscular Force Production and Hamstring Extensibility in Non power trained Individuals

Download or read book The Efficacy of Warm up and Stretching on Lower Extremity Muscular Force Production and Hamstring Extensibility in Non power trained Individuals written by Kimberly Ann Frostad and published by . This book was released on 2000 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective: To determine the effectiveness of moderate pre-exercise warm-up, static stretching, or a combination of both on muscular force production and hamstring extensibility of the lower extremity. Design and Setting: This experiment was a counterbalanced repeated measures design of four treatment conditions. Subjects participated in warm-up, static stretching, combined warm-up and stretching, and no treatment (control) on four separate testing days. After each treatment, hamstring extensibility was measured using the Active Knee Extension Test. Muscle force production was measured using a force dynamometer and associated software. Maximal voluntary isometric contractions of the quadriceps and hamstrings were assessed for the dominant limb. Subjects: Seventeen moderately physically active males and females with no history of lower extremity injury within the past six months were used in this study. Measurements: Angular displacement in degrees was assessed to determine hamstrings extensibility. Peak muscle force production (PFP) and peak rate of force production (PRFP) was assessed for quadriceps and hamstring isometric contractions. The differences between treatments were analyzed using a repeated measure analysis of variance. Outcomes: ANOVA revealed no statistically significant difference between treatments for the variables of hip flexion range of motion and peak force production. Post hoc comparisons revealed that peak rate of force production was significantly less for the stretching treatment compared to the other three conditions. The outcomes showed no difference between the active treatments and the control condition in muscle force production and range of motion.

Book Manual of Vibration Exercise and Vibration Therapy

Download or read book Manual of Vibration Exercise and Vibration Therapy written by Jörn Rittweger and published by Springer Nature. This book was released on 2020-05-23 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the practical aspects of vibration exercise and vibration therapy. In addition, it describes the technical and physiological background, providing applied scientists and doctors with a deeper understanding of the therapeutic potential that vibration exercise holds. Having first emerged two decades ago, vibration exercise has since established itself as a widespread form of physical exercise, used in all rehabilitation areas. The goal of this book is to close the gap between scientific knowledge and practice. Given that occupational exposure to vibration leads to well-known unfavorable effects, the book is also dedicated to potential risks, hazards and contra-indications and of course, the application of vibration therapy in a number of specific conditions is presented in a clinically usable fashion. Given its breadth of coverage, this book will be of interest to physiotherapists and exercise scientists, but also to a wider range of physicians working in the field of rehabilitation.
