Isokinetic strength aspects of human joints and muscles

Critical Reviews in Biomedical Engineering, Feb 1, 1991

Because of the growing need for better standardization and control of resistive exercises in dynamic conditions, not only in clinical but in research settings also (as training/testing devices, and as a method for scientific evaluation of the force-velocity relationship), development of special devices or dynamometers using computerized techniques became relevant. This article examines the perspectives of muscle function with respect to the particular characteristics of strength and velocity in general and to isokinetic strength aspects in particular in human joints and muscles. The &quot;isokinetic&quot; movement condition as a tool for assessing and rehabilitating strength, clinical, and ergonomic applications, and the limitations of the methodology, is critically reviewed.

Semg Measurements on Land and in Water Prior to and After 60- 90 Minutes of Submersion (Swimming) Are Highly Reliable

Isometric maximal voluntary contractions (MVC) on land and in water were collected of eight muscles in three males and three females (mean age 22.5±4.5 years). A paired samples t-test showed no significant differences in the mean MVC signal between pre and post test after prolonged water submersion (p<0.954 for average of the two highest MVC scores and p<0.946 for the highest MVC score pre and post submerging respectively). Intraclass Correlation (ICC)(1,1) were 0.977 and 0.972, the Chronbach's alpha was 0.976 and 0.972. The mean coefficient of variation for all muscles was 11%. Testing sEMG in water exercises, before or after a prolonged submersion seems to be highly reliable.
