What Is Muscle Strength Testing?
Muscle strength testing includes various methods designed to objectively measure the maximum force generated by a muscle or muscle group. These can be isometric, isotonic or isokinetic tests.
Hand Dynamometry
The most widely used strength test. Measures grip strength (kg). Correlates with overall body strength and health indicators.
Isokinetic Testing
Performed with special equipment (Biodex, Cybex). Measures strength at a constant speed throughout the range of motion.
Isometric Testing
Strength measurement without moving the joint — e.g., back extensor dynamometry, leg press against a platform.
1RM Testing
Determination of one-repetition maximum for specific exercises (squats, presses, pulls).
