Meeting Aerobic Physical Activity Guidelines and Associations With Physical Fitness in Men With Metastatic Prostate Cancer: Baseline Results of the Multicentre <scp>INTERVAL</scp>‐<scp>GAP4</scp> Trial
Bibliographic record
Abstract
ABSTRACT Background This study compared the physical activity level of men with metastatic prostate cancer at baseline of the multicentre INTERVAL‐GAP4 trial to the American Cancer Society guidelines and examined associations with physical fitness. Methods A total of 140 men on androgen deprivation therapy (ADT) were included in this cross‐sectional analysis of baseline data from the INTERVAL‐GAP4 trial. Exclusion criteria included a maximum of 1 h of vigorous aerobic exercise or one structured resistance exercise session per week but no restrictions on habitual physical activity. Moderate‐to‐vigorous physical activity (MVPA) was assessed using a modified Godin–Shephard Leisure‐Time Physical Activity Questionnaire. Physical fitness measurements included peak oxygen consumption (VO 2 peak), maximal power output ( W max ), 400 m walk time, one‐repetition maximum (1RM) of leg extension, leg press, chest press and seated row, and handgrip strength. Quantile regression was used to analyse associations of MVPA with physical fitness outcomes at the 25 th , 50 th and 75 th percentiles of the physical fitness distributions. Results Total self‐reported MVPA was 60 (IQR: 0, 180) min per week, with 29% meeting the aerobic physical activity guidelines. There was a statistically significant association of higher MVPA with higher relative VO 2 peak at the 25 th ( β = 0.53, p = 0.020) and 75 th percentiles ( β = 0.66, p = 0.001), relative W max at the 25 th ( β = 0.05, p = 0.003), 50 th ( β = 0.05, p = 0.009) and 75 th percentiles ( β = 0.07, p = 0.004) and reduced 400 m walk time at the 75 th percentile ( β = −4.26, p = 0.023), with β corresponding to the change in the dependent variable for each one‐hour increase in weekly MVPA. Conclusion Few men recruited to the INTERVAL‐GAP4 trial were meeting aerobic physical activity guidelines at baseline. Higher MVPA was associated with better aerobic capacity and walking performance but not maximal strength in men with metastatic prostate cancer on ADT.

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.
