Ecdysterone was tested in another study performed in 1986 by Smetanin. For this research, 117 highly trained speed skaters between the ages of 18 and 28 were tested for work capacity, body weight, lung capacity and VO 2 max. The results speak for themselves: all of the said parameters increased as well as an increase in the O 2 pulse max and an increase in the exhalation of CO 2 . Basically, they received more oxygen to their cells! This equates to decreasing recovery time, maximizing performance, permitting optimal muscle anabolism and maximum fat reduction. It also means the athletes using ecdysterone compared to those on a placebo experienced increased stamina, endurance and energy.
Shelton and Rajfer (2012) noted that androgen deficiency in aging men is common, and the potential sequelae are numerous. In addition to low libido, erectile dysfunction, decreased bone density, depressed mood, and decline in cognition, studies suggest strong correlations between low testosterone, obesity, and the metabolic syndrome. Because causation and its directionality remain uncertain, the functional and cardiovascular risks associated with androgen deficiency have led to intense investigation of testosterone replacement therapy in older men. Although promising, evidence for definitive benefit or detriment is not conclusive, and treatment of LOH is complicated.
