Modifiability of residual force depression in single muscle fibres following uphill and downhill training in rats
Bibliographic record
Abstract
Following active muscle shortening, steady-state isometric force is less than a purely isometric contraction at the same muscle length and level of activation; this is known as residual force depression (rFD). The purpose of this thesis was to investigate whether rFD in single muscle fibres is modifiable through downhill and uphill running in the extensor digitorum longus (EDL) and soleus (SOL) muscles in rats. Rats were randomly assigned to either a control or intervention group, where they were run uphill or downhill 5 days/wk for 4 wks. rFD was present for both the EDL (6-15%) and SOL (1-2%), with no effect of training. rFD was greater for the EDL than SOL which closely corresponded to the greater work of shortening and stiffness depression in the EDL. These results indicate that while rFD was observed, training did not appear to alter this intrinsic history-dependent property of single muscle fibres.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
