A Pilot Study on the Effects of Yi Jin Jing Exercise for Older Men with Benign Prostatic Hyperplasia.

Benign prostatic hyperplasia and its associated lower urinary tract symptoms seriously affect both the physical and mental health of older men. In order to determine the efficiency of Chinese Qigong Yi Jin Jing on prostate health in older individuals, thirty participants were randomized into either an Yi Jin Jing group (n = 15) or a control group (n = 15). After the 6-month intervention, the Yi Jin Jing group showed a significant decrease in international prostate symptom score and a significant increase in maximal urinary flow rate (compared with the control group p = .005, p = .001, respectively). Also, testosterone level increased and estrogen/testosterone ratio decreased in the Yi Jin Jing group (compared with the baseline p = .004, p = .002, respectively); estrogen level and estrogen/testosterone ratio were lower in the Yi Jin Jing group (compared with the control group p = .029, p = .012, respectively). The results showed that Yi Jin Jing is a promising way to reduce the risk of benign prostatic hyperplasia-lower urinary tract symptoms in older men.
