Aging and Cohort Changes in Sports and Physical Training from the Golden Decades Onward: A Cohort Study in Switzerland
Bibliographic record
Abstract
For most analysts, the Golden Decades (roughly 1950-1980) mark a period of far-reaching change – both structural and cultural – in Western societies. In an attempt to link the macro, societal transformation with individual behavior, the authors elaborate the “context-and-cohort-change” paradigm (as opposed to the “age-related-decline” paradigm), according to which they scrutinize the participation in sports and physical training at two stages (mid-life, third age) of adult life of the members of two cohorts (C1, born 1905-1914, N = 1012; C2, born 1920-1929, N = 661).The results show (a) a robust intercohort increase in the rate of exercisers from C1 to C2; (b) no significant longitudinal decline in participation from mid-life to third age, either in C1 or in C2, but a high rate of turnover among exercisers, with “late exercisers” filling the gaps left by the “dropouts”; (c) changes in the sociodemographic composition of exercisers, reflecting a move away from the pattern in which sports and physical exercise were mostly a male, urban, and upper-class activity, to another, much more generalized and democratic pattern.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
