Which statement best describes the use of dynamic concentric training?

• A. Strengthening when lifting resistance during the upward phase.
• B. Used in tasks requiring deceleration and landing.
• C. Stabilization training with no movement.
• D. Improving tendon lengthening under load.

Answer: (A)

Dynamic concentric training targets the muscle shortening as it lifts a load. This is best described by strengthening when lifting resistance during the upward phase, because during a concentric contraction the muscle fibers actively shorten to move the load upward.

Deceleration and landing rely on eccentric control to slow and absorb impact; stabilization with no movement uses isometric contractions with no change in muscle length; and tendon lengthening under load points to eccentric loading where the tendon and muscle lengthen under tension. So the upward-lifting strengthening idea captures the true essence of dynamic concentric training.
