the effects of aging on muscles are
decrease in size
fusion of muscle to bone
decrease in strength
decrease in mitochondria
increase in neural inputs

Explanation:

As people age, muscle mass (size) generally decreases (sarcopenia). Muscle strength also declines due to changes in muscle - fiber composition and reduced nerve - muscle communication. Mitochondrial function and quantity in muscle cells can decrease with age, affecting energy production. Muscle - to - bone fusion is not a typical effect of aging on muscles. Neural inputs to muscles usually decrease rather than increase with aging.

Answer:

decrease in size
decrease in strength
decrease in mitochondria
