Final answer:
Cardiac muscle contracts less forcibly when it is stretched.
Step-by-step explanation:
The statement is true. As cardiac muscle is stretched, it contracts less forcibly. When the cardiac muscle is stretched, the sarcomeres within the muscle are stretched as well. This causes the overlap between the myosin and actin filaments to be reduced, resulting in a decrease in the force of contraction. Stretching the cardiac muscle beyond a certain point can even lead to a decrease in the force of contraction.
