Summary
Brief summary (as posted)
Prostate cancer (PCa) patients receiving androgen deprivation therapy (ADT) (e.g., Zoladex), experience troublesome side effects during and after treatment (e.g., loss of lean body mass (LBM) and increased fat mass). Although the negative effects of ADT on muscle mass are well documented, the cellular effects of ADT on muscle tissue are still largely unknown, and studies investigating the mechanisms are highly warranted. Furthermore, understanding the cellular mechanisms through which ADT negatively influences muscle mass and glucose metabolism is important so that appropriate measures can be taken to counteract muscle wasting and comorbidities during ADT. Thus, PCa patients on ADT (Zoladex), along with non-ADT treated PCa patients serving as controls, will be invited to participate in this study, that aims to investigate the influence of ADT on the basal muscle protein turnover, as well as the responses to strength training. Secondary aims are to investigate between-group differences in blood glucose and insulin responses following a meal).

Primary outcomes (1)
- measure
- Muscle protein synthesis rate
- timeFrame
- The muscle biopsy will be collected two hours after the last exercise session.
- description
- The protein synthesis rate will be calculated based on the increased enrichment of deuterium, which will be ingested the week prior to the acute day, in muscle protein isolated from muscle biopsies. Deuterium enrichment is assessed by mass spectrometry.
