Abstract

fetched live from OpenAlex

A recent review by Cairns and colleagues published in Exercise and Sport Sciences Reviews (2005:33[1]:9-16)1 described experimental models used to study neuromuscular fatigue and explained the inherent strengths and weaknesses of applied versus reductionist approaches. This technical report addresses some of the recommendations made in that review, from the perspective of the applied sport scientist or practitioner in evaluating fatigue in elite athletes. The goal here is to highlight the inherent difficulties in assessing fatigue in the applied sport setting and to provide practitioners with future directions for fatigue research. A particular type of fatigue, called low-frequency fatigue (LFF), is of particular interest to the applied sport scientist or practitioner and could be the focus of future work. This report identifies some of the technical challenges faced in developing a practical test of LFF for use in the field setting. The outcome of further work in this area will lead to a better understanding of athlete monitoring, training, and performance.

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.

Not 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.
