Abstract
Regularly performed exercise in the form of endurance training produces a well-established adaptation in skeletal muscle termed mitochondrial biogenesis. The physiological benefit of this is an enhanced performance of muscle when subject to endurance exercise. This is not only of great advantage for athletic endeavours, but it also clearly improves the quality of life of previously sedentary individuals and those involved in injury rehabilitation. Here we review the molecular basis for mitochondrial biogenesis in muscle, from the initial signals arising in contracting muscle, to the transcription factors involved in mitochondrial and nuclear DNA transcription, as well as the post-translational import mechanisms required for the synthesis of the organelle. We discuss specific protein components associated with reactive oxygen species production, and suggest some questions which remain unanswered with respect to the role of exercise-induced mitochondrial biogenesis in ageing, apoptosis and disease.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
