1. Moving or operating at a constant speed or velocity; characterized by uniform motion.
Usage: technical; commonly used in exercise physiology and biomechanics
2. Relating to or denoting muscle contraction in which the muscle shortens at a constant angular velocity while maintaining maximum tension throughout the range of motion.
Usage: exercise science; physical therapy

Examples

• The isokinetic dynamometer measures muscle strength at a constant speed.
• Athletes use isokinetic training to build strength through a full range of motion.
• Isokinetic exercises allow the muscle to work at maximum force throughout the movement.
• Physical therapists often prescribe isokinetic rehabilitation after knee surgery.
• The isokinetic protocol ensures consistent testing conditions across all participants.
• Isokinetic contractions differ from isometric exercises, which involve no movement.
