FRIDAY, Dec. 29 (HealthDay News) -- Progressive resistance training may reduce side effects such as loss of muscle strength or accumulation of fat mass experienced by older men receiving androgen-deprivation therapy for prostate cancer, according to a report in the December issue of Medicine & Science in Sports & Exercise.
Daniel A. Galvao, Ph.D., of Edith Cowan University in Western Australia, and colleagues measured muscle strength and endurance, functional performance, balance and body composition in 10 men aged 59 to 82 years who agreed to progressive resistance training for 20 weeks.
The investigators found that strength and endurance, measured by performance on chest press, seated row and leg press exercises, improved dramatically over the time period and was accompanied by improvements in walking and balance tests. Blood analyses showed no significant changes in prostate specific antigen, testosterone, growth hormone, cortisol or hemoglobin.
"Randomized controlled trials are warranted to confirm these findings, and future studies should also include larger study groups, longer exercise periods (more than five months), and training during intermittent regimens of androgen-deprivation therapy," the authors conclude.
