Testosterone Boosters Help Replace Aerobic Capacity In Older Men
Chicago August 29th 2014
Announced at the joint meeting of the International Congress Of Endocrinology and the Endocrine Society recently held in Chicago were details of a study that looked into the effects of testosterone supplementation on older men with limited mobility and/or reduced aerobic capacity.
A placebo controlled randomised trial that ran over 6 months proved that improving the testosterone levels in sedentary or mobility older men boosted two measures of aerobic activity.
The trial consisted go 64 men with an average age of 73 who were given either a placebo or a testosterone supplement daily for 6 months.
The test subjects were then monitored for aerobic capacity by checking the changes over the period of peak VO2 and gas exchange lactate threshold while they carried out symptom limited exercise cycling
Gas exchange lactate threshold is a good way of assessing the test subjects ability toperform aerobic actions for long periods of time…. the group taking the testosterone supplement remained steady during the test period, while the half taking the placebo saw significant drops in their aerobic ability.
Dr Thomas Storer, the man in charge of the trial said:
“We think the mechanisms involved in this benefit are many,” Among them are testosterone’s demonstrated ability to increase muscle mass and thereby generate more force during exercise; increased RBC formation; stimulation of tissue capillarity in order to allow more blood flow to the exercising muscle; and stimulation of mitochondrial biogenesis, which increases oxygen uptake by muscle tissue.”
