Answer the following question given this paragraph: mitochondria, myoglobin, and capillary networks in SO fibers. Endurance athletes have a high level of SO fibers relative to the other fiber types. Resistance exercise causes hypertrophy. Power-producing muscles have a higher number of FG fibers than of slow fibers. Strenuous exercise causes muscle cell damage that requires time to heal. Some athletes use performanceenhancing substances to enhance muscle performance. Muscle atrophy due to age is called sarcopenia and occurs as muscle fibers die and are replaced by connective and adipose tissue. Q: Muscle atrophy due to age is called what? Choices: - nymphomania - Increased Atrophy - pepinia - sarcopenia A:
The answer to this question is:
sarcopenia
