Electromyographic (EMG) recordings were made during the assessment of arm strength and endurance of an isokinetic exercise in 25 high school women participating in a study designed to evaluate the response of young women to a male military training program. Force and EMG records were obtained during maximum voluntary contractions at isokinetic speeds of 5 and 15 RPM; and during a 30 sec isokinetic endurance trial at 15 RPM. The results indicated that, regardless of the type of training, army strength and endurance improved. (Author).

"The use of isokinetic exercise for assessing muscle function has been vastly incorporated in orthopedic and sports medicine. Isokinetic exercise allows major muscle groups to exert maximal force throughout the full range of motion (Perrin, 1993). To date, there is little information on the effects of rest interval length on isokinetic force production. The purpose of this study was to examine the effects of rest interval length on muscle efficiency and force output. The 37 subjects were recreationally active college students with no previous history of injury to the lower extremity, ages 21 to 35. Following a pre-test evaluation (three maximal voluntary contractions), subjects were randomly assigned to one of two groups: Group one performed 4 sets of 30 maximal isokinetic quadrceps contractions on the Biodex Systems II isokinetic dynamometer with a 60-second rest interval between each set. Group two performed the identical exercise protocol as group one with the exception of a five-minute period of rest in between each set. Prior to and following the four sets of isokinetic contractions, the subjects performed three MVC's with the knee at an angle of 60 degrees. Electromyography (EMG) will be used to assess muscle fatigue within the two rest interval groups. A two-minute period of rest is taken in between each isometric contraction. Peak quadriceps torque decreased regardless of the rest interval (F = 70.6, p = 0.01). IEMG amplitude did not change following fatigue in the vastus lateralis and rectus femoris. However, data indicated a significant test effect in EMG mean frequency with the vastus lateralis (F = 41.34, p = 0.01) and rectus femoris (F = 79.35, p = 0.01) and group (F = 10.48, p = 0.03) effect. Such findings in EMG reveal a fatiguing effect upon the quadriceps muscles"--Document.

Principles and Practice of Isokinetics in Sports Medicineprovides a comprehensive, critical review of isokinetic technology applied to sports training program testing and rehabilitation following injury and surgery. Featuring the work of renowned international contributors, the reference presents a step-by-step guide on practical isokinetic procedures and examines the significance and validity of variables commonly measured. The scientific value of isokinetics is highlighted both for sports medicine and sport sciences, enabling sports medicine practitioners to identify the merits of isokinetics and its relevant applications. The use of isokinetics in injury diagnosis and rehabilitation is outlined with specific illustrations from research data collected at the Chinese University of Hong Kong. Special attention is given to assessment of the most commonly injured sites: the knee, ankle, shoulder, and trunk. The reference offers guidelines for the interpretation of test results along with examples of how to apply the guidelines in designing appropriate rehabilitation programs. A special section is devoted to the use of isokinetics in the assessment of sport performance. Extensive photographs, charts, and illustrations throughout the reference highlight key points.

It is over 25 years since isokinetic dynamometry was first introduced into clinical practice and exercise science. Physical therapy, in particular, has benefited significantly from this technology, which rapidly became the tool of choice in hundreds of research papers as well as the cornerstone of quantitative muscle performance assessment in the clinical setting. About 1984, the technology behind isokinetic dynamometry made considerable progress when computers were incorporated to control the hardware, that is the integral power sources and the on-line processing of mechanical signals. This enabled users to establish a common basis for carrying out eccentric contractions and to obtain comprehensive information on muscle strength immediately. This book does not pretend to cover all the topics that have been examined under isokinetics. Nor is it intended to be a quick and superficial introduction to clinical applications. Rather, it is aimed at those who have at least some experience and are at a stage where they are beginning to ask some very serious questions and would not necessarily be happy with very simple answers.

IntroductionThe risk factors for falls in patients with osteoporosis have certain particularities given the consequences of fractures and the increased mortality.PurposeOur assumption is that isokinetic training can improve the balance impairment in patients with osteoporosis and therefore decrease the incidence of falls.Method30 patients with primary osteoporosis were included in the study. The study took place over 10 days with the assessments being performed on day 1 and 10. We used the following tests: chair rise, up and go, and tandem test. Isokinetic training was fixed, daily, for 10 days, bilaterally, including repetitions of flexion and extension of the knee at 150, 180, 240 grd/sec, each of 10 repetitions with 20 seconds pauses.ResultsFor the chair rise test, and up and go test, although there was an improvement, we found no significant correlations between day 1 and 10 (p = 0.73 and p = 0.63).The tandem test improved, without reaching significant correlation (p = 0.06).A good correlation was observed for the chair rise and up and go test. This correlation has negative values for the maximum extension torque, Peak Torque average per extension and maximum extensional strength at both day 1 and day 10. Decrease in the performance of the balance tests was carried out concomitently with the increase of the torque and the power on the extension, thus implicitly of the extension force. This is very important from a practical point of view because it shows a much faster and more objectively improvement in force than the balance tests. ConclusionsA statistical significance for the tests was not found because the duration of the study was relatively short. In other studies with similar objectives, these tests were interpreted together and not separately. In short period of time isokinetic parameters shows much faster improvement than balance test.
