Isometric assessment of muscular function is a popular form of testing which has been used
in exercise science for over 40 years. It typically involves a maximal voluntary contraction
performed at a specified joint angle against an unyielding resistance which is in series with
a strain gauge, cable tensiometer, force platform or similar device whose transducer
measures the applied force. Often both the maximum force and the rate of force
development are recorded. These tests have generally shown high reliability in both single …
