Final answer:
Many researchers use a muscle mass/strength ratio known as muscle quality to assess muscle health and performance. This measure provides valuable insights into the functional capabilities of muscles, especially in aging populations and physical rehabilitation. The correct option is B.
Step-by-step explanation:
In addition to the 10 established biomarkers, many researchers now use a muscle mass/strength ratio called muscle quality. This ratio is considered an additional marker for assessing the health and functionality of muscles, particularly as individuals age.
Muscle quality is used over other metrics like Rosenberg's ratio, movement quantity, or a secondary biomarker ratio because it provides a measure of the force a muscle can produce relative to its size.
This concept is particularly useful in the field of geriatrics and physical rehabilitation, where muscle strength and health are crucial for maintaining independence and quality of life.
