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.

Available in PDF, EPUB and Kindle. Book excerpt: Stretching is a fundamentally important part of sport and exercise, playing a role in improving performance, and preventing injury and rehabilitation, but its scientific underpinnings have, to this point, been overlooked in book publishing. The Science and Physiology of Flexibility and Stretching is the most up-to-date and comprehensive book to cover the underlying physiology and psychology of stretching, critically assessing why, when, and how we should stretch, as well as offering a highly illustrated, practical guide to stretching exercises. Placing stretching in the context of both health and performance, the first section of the book sets out the science behind stretching, critically assessing the benefits, disadvantages, and roles of different types of stretching, exploring the mechanisms behind increasing range-of-movement through stretching and other methods, and offering evidence-based guidance on building stretching into warm-ups. In its second section, the book provides a step-by-step guide to static, dynamic, and PRF stretching exercises for beginners, through recreational athletes, to elite performers. Richly illustrated, and including an online resource, The Science and Physiology of Flexibility and Stretching provides an important scientific enquiry into stretching, and an invaluable reference for any strength and conditioning coach or student, personal trainer, sports coach, or exercise scientist.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to investigate the effects of active warm-up (stationary cycling) and passive warm-up (heat pack) on the mechanical properties of the hamstring musculature in vivo. Passive tension measurements were recorded during the passive knee extensions of ten men before and after an active warm-up, passive warm-up, and control treatments. The results of the present investigation revealed no effect of active warm-up or passive warm-up on the passive tension variables of energy absorbed, energy returned, peak torque, average stiffness, or peak stiffness of the hamstring musculature. These findings suggest that the mechanical properties of the connective tissue were unaltered by the warm-up techniques utilized in this study. Although these results do not support the use of active or passive warm-up to facilitate increased muscle tendon unit compliance to stretching activity, we do not recommend discontinuation of these practices before athletic competition, exercise, physical recreational activity, or stretching exercise.

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.

Download or read book Comparing the Effects of Two Proprioceptive Neuromuscular Facilitation Stretching Techniques and Static Stretching on Active Knee Extension Range of Motion and Vertical Jump Performance written by Nick Vaillant and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Proprioceptive neuromuscular facilitation (PNF) stretching has often been identified as an effective stretching technique for improving range of motion (ROM) prior to exercise. The two PNF stretching techniques that are most commonly performed are autogenic inhibition and reciprocal inhibition stretching. These techniques increase ROM by applying resistance to either agonist (i.e. autogenic) or antagonist (i.e. reciprocal) muscle groups to reduce reflex activity. Variability in PNF stretching procedures, however, cause difficulty comparing studies and translating findings to clinical practice. Limited research has also been performed on the effects of PNF stretching on athletic performance. The present study compared the effects of static, autogenic inhibition, and reciprocal inhibition stretching on knee extension ROM and vertical jump performance. Thirty healthy participants (16 male and 14 female) performed an Active Knee Extension test and a Vertical Jump test after 4 counter balanced stretching conditions. The stretching conditions consisted of no stretching (control), static stretching, autogenic inhibition stretching, and reciprocal inhibition stretching. A one-way analysis of variance (ANOVA) with repeated measures and the Bonferonni post hoc test identified static stretching, autogenic inhibition stretching, and reciprocal inhibition stretching significantly increased knee extension ROM by means of 7.8, 8.1, and 9.4 degrees, respectively when compared to no stretching (p.001). No significant differences were identified between the ROM increases associated with each technique (p0.05). Pairwise comparisons also identified no significant differences in vertical jump height (cm) before or after the use of static, autogenic inhibition, or reciprocal inhibition stretching (p>0.05). The present study was the first to compare these stretching techniques using recommended pre-activity procedures. The results of this study identified all three stretching techniques as effective techniques for improving ROM prior to exercise without decreasing vertical jump performance.
