Isokinetics and Exercise Science (IES) is an international journal devoted to the study of theoretical and applied aspects of human muscle performance. Since isokinetic dynamometry constitutes the major tool in this area, the journal takes a particular interest in exploring the considerable potential of this technology.
Isokinetics and Exercise Science publishes studies associated with the methodology of muscle performance especially with respect to the issues of reproducibility and validity of testing, description of normal and pathological mechanical parameters which are derivable from muscle testing, applications in basic research topics such as motor learning paradigms and electromyography. The journal also publishes studies on applications in clinical settings and technical aspects of the various measurement systems employed in human muscle performance research.
Isokinetics and Exercise Science welcomes submissions in the form of research papers, reviews, case studies and technical reports from professionals in the fields of sports medicine, orthopaedic and neurological rehabilitation and exercise physiology.
Abstract: BACKGROUND AND OBJECTIVE: Maximal voluntary isometric contraction (MVIC) is used to determine both peak torque (PT) and rate of torque development (RTD). Familiarization sessions are usually performed to stabilize PT and RTD when performing MVIC. However, it is not clear how many familiarization sessions are required to achieve such stability in different age groups. METHODS: Thirty-three healthy individuals were divided into three groups: young group (YG; 5 men and 7 women, age 22.75 ± 4.53 years), middle-aged group (MAG; 6 men and 5 women, age 50.45 ± 6.12 years) and elderly group (EG; 6…men and 4 women, age 67.80 ± 7.28 years). Individuals performed the MVICs using an isokinetic dynamometer, in four different occasions separated by at least 72 hours. RESULTS: There were no differences in PT and RTD between familiarization sessions for all age groups (P > 0.05). CONCLUSIONS: Our findings suggest that the present protocol of MVIC is capable of stabilizing PT and RTD in the first testing session in young, middle-aged and elderly groups.
