Effects of Short-Term Resistance Training on Muscle Strength and Morphology in the Elderly
Bibliographic record
Abstract
Ten moderately active participants (8 women, 2 men; mean age 66.3 ± 1.2 years), engaged in 8 weeks of isotonic knee-extensor resistance training. Afterward, peak torque output (180°/s) and mean power increased 30.8% and 27.2%, respectively, in the experimental limb (EL). A moderate, nonsignificant cross-over training effect was observed in the contralateral untrained limb (CL) for the same measures. Whereas mean fiber cross-sectional area (CSA) was unaltered in the CL by training. Fiber Types I and lib in the EL displayed increased CSA. However, mean CSAs for all fiber types in the trained EL were no larger (p > .05) than those observed in the CL before or after training. There were no significant changes in muscle-fiber-type composition, the proportion of Type I myosin heavy chain, or Type Ha CSA. These data suggest that short-term resistance training can significantly increase isokinctic peak torque in the elderly, with minimal changes in the histochemical and biochemical parameters examined.

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.
