Veldekens and published by . This book was released on 1996 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to examine the effect of isokinetic eccentric muscle training activities in comparison with isotonic eccentric muscle training activities of the quadriceps muscle for knee extension (torque, work, and power). Forty-five healthy female volunteer subjects between the ages of 22 and 64 were recruited for this training study. the null hypotheses were that there would be no difference between the control, isotonic and isokenetic groups and no difference in the baseline to post training sessions. All subjects had an orthopaedic screening of their lower extremities. In a test/retest experimental design, the right quadriceps muscle groups of each subject was tested in the isokinetic mode with an eccentric/extension contraction. Subjects were divided into three groups--Eccentric Isotonic (ET), Eccentric Isokinetic (EK), and the Control (C). the EK training included 5 eccentric knee extension and flexion contractions on the BioDex Unit at the speeds of 60, 60, 75 and 75 degrees per second. Five repetitions were done with a 10 second rest. the ET group was exercised in the isotonic mode on the BioDex. the ET performed twenty eccentric exercise repetitions at each training session. the resistance load was adjusted for each subject through the training interval to assure isometric maximal quadriceps loading (in extension) for twenty repetitions. Twenty-four training sessions were performed at the same time of day for both groups. the control group was not trained. Subject performance data on peak torgue (PT) and total work (TW) was collected on the computer system using SYSTAT. A two-way ANOVA was used to determine the effect of group on peak torque and total work. Statistically the results showed that no significant differences existed between the isokinetic eccentric and the isotonic eccentric training for knee extension. Power using a vertical jump test after training was not significant either. An ANCOVA analysis was performed with pretraining measurements of torque as the co-variable. Although there were no significant differences from any of the dependent variables, there was a slight trend for improvement in isokinetic eccentric training, primarily in the variable of total work.

Download or read book A Comparison of Hypertrophy, Strength and Power Changes Between Eccentric Isotonic and Eccentric Isokinetic Leg Training written by Gail M. Trojack and published by . This book was released on 1986 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of 6 week eccentric isotonic and eccentric isokinetic training programs on hypertrophy, strength and power development in the quadriceps were compared. Male Ss (N=22) participated including 7 training isotonically (T), 7 training isokinetically (K), and 8 control subjects performing no resistance leg training (C). Ss performed 3 sets of 10 repetitions on Monday, Wednesday and Friday with an additional set on Friday to systematically adjust work load. No group significantly increased thigh girth or body weight. Both groups exhibited carryover of concentric strength from eccentric training in certain tests. (T) improved significantly over (C) in isotonic concentric one repetition maximum, 5 second isometric, and both Margaria Kalaman power tests. (T) improved significantly over (K) in the concentric isotonic one repetition maximum as well. (K) improved significantly over (C) in average concentric peak torque (170°/second) and in the Margaria Kalaman power test at 6 meters. Both groups exhibited carryover of strength when tested at fast speeds from slow speed training programs (60°/second). (T) improved significantly over (C) in average eccentric peak torque (170°/second) and the Margaria Kalaman tests of power. (K) significantly improved over (C) in average concentric peak torque (170°/second), eccentric total work (170°/second) and the Margaria Kalaman power test at 6 meters. Both groups significantly improved over (C) in eccentric isotonic one repetition maximums. Only (K) significantly increased average eccentric peak torque at 60° /second over (C).

This book was released on 1985 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examined the effects of a 7 wk eccentric isokinetic training program (60 degrees/sec) on peak torque (PT), total work (TW)and peak torque/body weight (PT/BW) of the knee extensors. Thirty-one men and women from the University of Wisconsin- La Crosse physical education and physical therapy classes participated in the study. Ss were tested for strength on the KIN-COM at 60 degrees/sec and 180 degrees/ sec, pre and post a 7 wk training program. The experimental group (20 Ss)performed 3 sets of 10 repetitions of eccentric knee extensions at 60 degree/sec 3 times a wk for 7 wks. The control group consisted of 11 Ss. A t-test for independent samples of mean differences between the 2 groups was done ti determine if the training program would cause a significant increase in strength at both slow and fast velocities.

This book was released on 2003 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Purpose. The purpose of this study was to increase power via a combined high velocity isokinetic, and low velocity, heavy resistance isotonic, training regimen. Methods. Twenty-nine subjects (aged 19-29 yrs) were pre- and post-tested for the following dependent variables; vertical jump leg power (VJP) and vertical jump height (VJH); Wingate peak anaerobic power (PkAnP), Wingate PkAnP kg-1, and Wingate mean anaerobic power (MAnP); isotonic one-repetition maximum (1RM) squat, knee flexion, and knee extension; and isokinetic peak torque (PT) and time to peak torque (TPT) at 60, 180, 300, 400, and 500°sec-1. Subjects, who were randomly assigned to three groups, trained twice a week for 10 wks. Group 1 (n=9) performed isotonic knee flexion and extension exercises, Group 2 performed seated isokinetic consecutive knee extension-flexion (concentric-concentric) exercises, and Group 3 performed a combination of the isotonic and isokinetic exercises of groups 1 and 2. All groups also performed squats at the start of each training session. Results. Significant improvements were revealed from pre- to post-test for all dependant variables regardless of group. Peak torque extension values were significantly greater for group 1 than group 2 (mean difference= 14.2 ft lbs, SEE= ±6.04; p

Available in PDF, EPUB and Kindle. Book excerpt: Laterality in Sports: Theories and Applications summarizes recent research on the neurophysiological foundations of handedness, and how left or right lateralization (affecting primary hand use, foot use, and eye use) affects motor control, performance outcome, skill acquisition, and achievement of sports expertise—both for one-on-one sports and team sports. As laterality research has matured, greater focus has been given to applications in human endeavours and, in particular, sport. The book examines performance within individual sports, and discusses the coaching ramifications of coaching to a specific lateralization preference. Describes the neurophysiological foundations of handedness Discusses the origins and development of laterality in humans Summarizes the impact of laterality on motor control and sports performance Encompasses research on both individual and team sports Includes research on skill acquisition, coaching, and development of expertise Covers research on laterality in preferred hand, foot, and eye use in sports
