Isokinetic Exercise
Introduction[edit | edit source]
Isokinetic exercise or accommodating variable-resistance exercise, refers to force exertion against the isokinetic machine that leads to limb movement at a fixed velocity. [1]In other words, it refers to exercises whose limb velocity remain stable throughout the range of motion, and thus, muscle force and resistance in the machine are changing to meet this requirement. [1]
Types of Isokinetic Exercise[edit | edit source]
Isokinetic exercises may be concentric-concentric, concentric-eccentric, or eccentric-eccentric.[1]
Isokinetic Assessment[edit | edit source]
Isokinetic machines can be used in movement assessment.
Control of speed in movement assessment may provide valuable insights on individual dynamic muscle patterns while providing stability to the testing positions. [2]
Assessment of isokinetic eccentric movement can be performed either by (1) setting up a predetermined load and having the lever arm drive the extremity at the predetermined velocity, or (2) working against a passively moving lever arm at the predetermined velocity. [2]
Collected data is in a machine-specific format and different data handling software programmes are used for different machines. [2] Thus, users need to be familiar with this type of data analysis and interpretation, which does not necessarily reflect functional patterns of performance.
