Activity 9 isotonic contractions lab

The topics of this chapter have been adapted from Volume 1, Chiropractic Rehabilitation, by K. Knowledge of various training methods and exercise techniques are thus among the most important requirements for effective treatment.

All exercise programs should have specific goals in mind. The patient who participates in a well-devised, scientifically based, properly instructed exercise program should benefit in at least four areas: Enhanced musculoskeletal performance 2.

Decreased risk of injury 3. Decreased severity should an injury occur 4. Accelerated rehabilitation and return to activity after injury.


Reid and Schiffbauer indicated that hypertrophy of muscle through exercise protects against bodily injury. There are three basic types outlined: Isotonics can be divided into a concentric positive movement, an eccentric negative movement, and variable resistance.

The isokinetic type can also be divided into a concentric or eccentric movement or both. These types of exercises can be defined and contrasted in terms of the speed of movement and the resistance applied.

In isometrics, we know that the speed of movement is fixed and the resistance is fixed. The resistance in isotonics is fixed the amount of weight lifted.

Knowledge Base

In isokinetics, the speed is fixed but the resistance is variable. Thus we can see that isokinetics is the opposite of isotonics. These types of exercises can be designed in musculoskeletal rehabilitation to optimize joint integrity by strength.

Static isometric exercise is performed without producing joint motion. The muscle exercised maintains a fixed length. Kinetic isotonic exercise is performed to produce joint movement. Contracting muscles shorten, causing movement of the joint at which they are attached.Activity 3: Recruitment and Contractions PREDICTIONS 1.
