1. When muscle tension develops but the load is not moved. 2. Determined by alternating motor units of a muscle organ even when the muscle is at rest. 3. Continued sustained smooth contraction due to rapid stimulation. 4. When the muscle tension developed overcomes the load and muscle shortening occurs. 5. How a smooth increase in muscle
