The power of isokinetics is its simplicity: removing the complexity without removing the challenge. Control the speed to create the stimulus, not by stacking plates on a bar or machine. Let's dive into what this type of resistance is and why it's a game-changer for your athletes.
1. What Are Isokinetics?
-Iso-kinetic, meaning "same" "velocity," is a type of resistance where the athlete moves at a fixed concentric speed limit
-The motor measures in real-time how much force the athlete is producing and creates an equal and opposite amount to keep the athlete at the speed limit
-The speed is controlled so force becomes the measurable output

2. Max Force Output
-Because the speed is fixed the entire time, the athlete can create maximum force throughout the entire range of motion of the movement. As opposed to an isometric which is max force only in that one position/joint angle
-This gives a high-intensity strength training stimulus without any external load on the athlete. No barbells or dumbbells needed
3. Why It Matters
-Concentric-only work yields minimal soreness, for example making it an ideal stimulus for in-season training
-Combine isokinetic force measurements with subjective cues, like "pull with no pain" or a "3 of 10 effort," to objectively track progress during rehab
-Quantify strength and symmetry of any movement

Summary
-Isokinetics are a unique form of resistance training with many applications from strength training to rehab
-The simplicity gives it versatility, letting the coach create and track true maximum force training stimuli that's difficult to achieve any other way
