MICROANATOMY

Detailed explanation-1: -Therefore, a bigger muscle-in terms of its cross-sectional area-is also a stronger muscle. This means that individuals with long muscle bellies have the potential to be quite strong.

Detailed explanation-2: -Although a general positive relation exists among the two variables, a number of studies show a clear dissociation with increase of muscle size with no change or even decrease in strength and, vice versa, increase in strength without increase in size.

Detailed explanation-3: -Thus, an increase in the thickness of muscle fiber is called Hypertrophy.

Detailed explanation-4: -Larger muscle fibers generally produce more force than smaller muscle fibers, which shouldn’t be much of a surprise. Bigger muscle fibers tend to be stronger muscle fibers. From Gilliver, 2009. However, while absolute strength of muscle fibers tends to increase with fiber size, relative strength tends to decrease.
