Abstract

fetched live from OpenAlex

This brief review examines the likelihood that a deterioration of aerobic fitness will lead to a loss of independence in old age. The rate of deterioration of maximal aerobic power observed in middle-aged adults continues unabated during the retirement years. Loss of independence seems likely if maximal oxygen intake falls below a threshold of 18 ml/[kg x min] in men and 15 ml/[kg x min] in women, reached at 80-85 years. A regular programme of aerobic exercise can slow or reverse the functional deterioration, reducing the individual's biological age by 10 or more years, and potentially prolonging independence by a similar amount. There remains a need to clarify the importance of decreasing aerobic fitness relative to other potential causes of dependency but, from the practical viewpoint, regular aerobic activity should be commended to elderly people since it can address many of the issues of both functional loss and chronic disease.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
