Not a strategy to minimize end range motion?

Not a strategy to minimize end range motion?

• A. Improve body position
• B. Use the power zone
• C. Keep arms extended away from body
• D. Use a carry aid

Answer: (C)

The key idea is to keep loads close to the body and work within a comfortable, mid-range of joint motion to reduce strain at the ends of the range. Keeping arms extended away from the body does the opposite: it lengthens the lever arm and pushes the load outward, increasing shoulder and elbow extension toward the end range and raising the torque on the joints. This makes the lift harder and more stressful at the extremes, not easier. Improving body position helps by reducing awkward postures and keeping the load near the center of gravity. Using the power zone keeps the movement in a joint range where the muscles are strongest, lowering end-range stress. Using a carry aid brings the load closer to the body and reduces reach and end-range demands.
