## Step 1An isotonic eccentric contraction is a type of muscle contraction where the muscle lengthens under tension. This is the opposite of a concentric contraction, where the muscle shortens.## Step 2In the context of the triceps, an isotonic eccentric contraction would involve the triceps muscle lengthening while still maintaining tension. This typically occurs during the controlled lowering phase of an exercise.## Step 3In the given options, the "Lowering phase (elbow flexion) in a push-up" is the phase where the triceps are lengthening under tension as the elbow is being flexed. This is an example of an isotonic eccentric contraction for the triceps.
