Question

Which one of the following statements regarding the muscle adaptation is incorrect? group of answer choices

-increased muscle fiber length (sarcomeres in series) increases the power production in a muscle.
-increased activation of synergist muscles and decreased activation of antagonist muscles occur when there is an increase in muscle pcsa.
-neural adaptations can increase muscle strength significantly without an increase in pcsa.
-chronic lengthening (stretching) can result in an increased sarcomere number.
-an adaptively shortened muscle may reduce the range of motion over which you can produce torque.

Answer 1

The incorrect statement about muscle adaptation is that increased muscle fiber length (sarcomeres in series) increases the power production in a muscle, which is false because optimal power is associated with the optimal range of sarcomere length and cross-bridge formation.

Step-by-step explanation:

Muscle Adaptation Incorrect Statement

The incorrect statement regarding muscle adaptation is that "increased muscle fiber length (sarcomeres in series) increases the power production in a muscle." This statement is false because the power of a muscle is more so related to the number of cross-bridges that can be formed during muscle contraction rather than the length of muscle fibers. In fact, sarcomere length has an optimal range for power production, and if a muscle is stretched too much or not enough, it won't produce maximal force. An increased number of sarcomeres in series can increase the range of motion and speed of contraction, but it does not directly correlate to an increase in force or power of the muscle.

Other statements such as "neural adaptations can increase muscle strength significantly without an increase in PCSA," "chronic lengthening (stretching) can result in an increased sarcomere number," and "an adaptively shortened muscle may reduce the range of motion over which you can produce torque" are all accurate descriptions of muscle adaptation processes.
