Effects of resistance training frequency on physical functioning and quality of life in prostate cancer survivors: a pilot randomized controlled trial

Abstract: This pilot randomized dose-comparison trial provides preliminary data to suggest that RT 3 days per week compared with 2 days per week may improve the strength and physical functioning in prostate cancer survivors, but may also blunt improvements in psychosocial functioning. Larger and more targeted phase II and III trials are needed to confirm the potentially complex effects of RT frequency in prostate cancer survivors.

“…For supervised exercise, no dose–response relationship was found between weekly energy expenditure and the effect on self-reported QoL or PF. A previous RCT reported a higher dose of supervised AE to be related to larger effects on PF,9 while a higher frequency (3 vs 2 days/week) of RE was related to higher effects on the physical component summary (including PF) 115. In the current meta-analysis, the dose–response relationship between weekly energy expenditure and the effect of exercise on self-reported QoL and PF was investigated for AE and RE combined.…”

“…More recently, a few studies have begun to investigate different doses, frequencies, timing, and progression of strength training in cancer survivors. Norris et al examined the effects of strength training frequency (2 d/wk vs 3 d/wk) on strength, physical function, and psychosocial outcomes in prostate cancer survivors over 12 weeks. The addition of a third day of strength training improved strength and physical functioning in prostate cancer survivors but may also blunt improvements in psychosocial functioning.…”

“…Given that few randomised controlled trials focusing on these outcomes included men not treated with ADT [38], these observations are an important contribution to the literature. Developing and maintaining muscle strength is imperative, because low muscle strength is an independent predictor of impaired mobility [39] and all-cause mortality [40] in older adults.…”
