Understanding Angular Velocity (°/s)
In isokinetic testing, Angular Velocity ($\omega$)refers to the preset constant speed at which the dynamometer lever arm rotates, measured in degrees per second (°/s).
The Velocity Spectrum & Rationale
SLOW VELOCITY (30–60°/s)
Maximal Force & High Unit Recruitment
Maximizes cross-bridge formation time, allowing full motor unit recruitment. Used to evaluate absolute peak torque capacity and maximum strength.
INTERMEDIATE (120–180°/s)
Strength-Endurance & Standard Ratios
Standard clinical testing velocity balancing force output with movement speed. Ideal for conventional H:Q ratio benchmarking.
FAST VELOCITY (240–300°/s)
Power Output & High-Speed Work
Evaluates rapid torque production, power, and metabolic fatigue resistance during high-repetition bouts (20–30 reps).
