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.

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.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Purpose: The primary purpose was to determine whether or not static and/or dynamic stretch techniques affect the peak torque and average power of the shoulder rotators. A secondary purpose was to assess and compare range of motion after the two stretching techniques. Methods: Using a cross-over design, 16 recreationally active females (18-35 yrs) participated in three sessions (baseline, static stretch, dynamic stretch) separated by at least 48 hours. Each subject warmed-up for five minutes before being tested for peak torque and power measurements, using Biodex System 3 Isokinetic dynamometer with 5 repetitions at 60°/second and 180°/second, and range of motion with a standard universal goniometer was also measured. In sessions two and three, the participant performed either 3x15 repetitions of five dynamic stretches or 3x25 second holds of five static stretches between warm-up and testing. Subjects were randomized as to the order of stretch sessions. Results: No significant differences were found between stretch protocols.

Book excerpt: Abstract: The purpose of this study was to determine the effects of limited range of motion (ROM) isokinetic knee extensor exercise on isometric strength development inside and outside the trained ROM. Four male and 18 female volunteers between the ages of 20 and 48 years were randomly assigned to one of two groups. The experimental group trained the knee extensors isokinetically on the KINCOM from 45 to 0 degrees of knee flexion three times a week for five weeks. The control group did not train. Both groups were pretested and posttested on the KINCOM for isometric knee extensor peak torque at 15, 25, 35, 55, 65 and 75 degrees of knee flexion. One half of the subjects in each group was tested at each angle in ascending order, while the other half was tested in descending order. The two orders of testing were randomly assigned and balanced over subjects with a matching procedure. Repeated-measures ANOVA with one between groups factor was used to determine if significant differences existed between the groups. Tukey's Honestly Significantly Different test was used to make pairwise comparisons between group means at each angle. Upon statistical analysis it was determined that no significant differences existed between the groups at each angle of measurement except at 75 degrees of knee flexion (p
