Intersegmental transfer reduces muscle work because muscles only need to generate what portion of total movement power?

Intersegmental transfer reduces muscle work because muscles only need to generate what portion of total movement power?

• A. A fraction
• B. All
• C. None
• D. Twice as much

Answer: (A)

The idea being tested is that in multi-segment movements, energy and momentum can be transferred between segments, so muscles don’t have to supply all the work themselves. When one segment accelerates, its inertia can help drive the next segment through joints and connected tissues. This means the total movement power is shared, and muscles only need to generate a portion of it. That makes the correct choice a fraction of the total movement power. In real movement, this transfer relies on coordinated timing and the body’s passive properties, so overall muscle effort is reduced compared to trying to move everything with one muscle group alone.
