Question at position 45 Muscle fibers produce more mitochondria and glycogen stores as a response to increased physical training.TrueFalse

Question

BlackTom AI · Accepted Answer

The question asks about muscle fiber adaptations to increased physical training and presents two options: True or False.
Option 1 (True): This statement is accurate. When muscles undergo progressive training, especially endurance-type or mixed modalities, they commonly adapt by increasing mitochondrial density and volume (mitochondrial biogenesis) and enlarging glycogen stores within muscle fibers. These changes enhance aerobic energy production and energy availability during activity, contributing to improved endurance and performance. Mechanistically, factors such as PGC-1α activation promote mitochondrial biogenesis, while enzymes involved in glycogen synthesis and storage are upregulated to stockpile glycogen for quicker glucose availability during repeated contractions.
Option 2 (False): This would be incorrect because the body’s adaptive response to training includes both increases in mitochondria and glycogen stores; saying they do not change would ignore well-documented muscle adaptations. Additionally, restricting adaptations to other systems or claiming no change in energy substrates would misrepresent how training-induced metabolic remodeling occurs in skeletal muscle.
In summary, the statement aligns with established exercise physiology concepts about structural and metabolic adaptations in muscle fibers in response to increased training volume and intensity.
