Abstract

Objectives To investigate whether functionally based resistance exercise could improve strength, physical function, and disability among prostate cancer survivors (PCS) on androgen deprivation therapy (ADT); and to explore potential mediators of changes in outcomes from exercise.Design Randomized controlled trial.Setting Academic medical center.Participants PCS (N=51; mean age, 70.2y) on ADT.Intervention PCS were randomized to moderate to vigorous intensity resistance training or stretching (placebo control) for 1 year.Main outcome measures Maximal leg press and bench press strength, objective and self-reported physical function, and self-reported disability. Hierarchical linear modeling was used to test for significant group × time differences adjusting for covariates.Results Retention in the study was 84%, and median attendance to supervised classes was 84% in the resistance group. No study-related injuries occurred. Maximal leg strength (P=.032) and bench press strength (P=.027) were improved after 1 year of resistance training, whereas little change occurred from stretching. Self-reported physical function improved with resistance training, whereas decreases occurred from stretching (P=.016). Disability lessened more with resistance training than stretching (P=.018). One-year change in leg press strength mediated the relation between groups (resistance or stretching) and 1-year change in self-reported disability (P<.05).Conclusions One year of resistance training improved muscle strength in androgen-deprived PCS. Strengthening muscles using functional movement patterns may be an important feature of exercise programs designed to improve perceptions of physical function and disability. Findings from this study contribute to the mounting evidence that exercise should become a routine part of clinical care in older men with advanced prostate cancer.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Neuromuscular contributions explain up to 50% of variation in muscle strength in older adults, so resistance training in ADT or deconditioning may still improve muscle strength without muscle mass gains.

    “neuromuscular contributions explain up to 50% of variation in muscle strength in older adults, thus resistance training in the setting of ADT or deconditioning may still effectively improve muscle strength in the absence of gains in muscle mass(97).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
