All initially underwent arterial blood circulate testing as a measure of coronary heart well being and performance, earlier than being randomly divided into 4 teams. One group did cardio and power train two to a few instances per week whereas receiving testosterone remedy; a second received testosterone alone; a 3rd was given placebo remedy; and a fourth received placebo remedy with an train routine.
The workforce discovered that by itself, train triggered an increase in testosterone ranges, although to not the identical extent because the 62% rise in hormone ranges seen amongst males who did bear testosterone remedy.
However most critically, arterial operate shot up by 28% amongst those that exercised with out taking testosterone remedy. That bested the 19% enchancment seen amongst these exercised and took testosterone substitute remedy.
These males who solely obtained testosterone remedy noticed no coronary heart well being enchancment in any respect. The researchers concluded that train could also be preferable over testosterone supplementation to enhance coronary heart well being in older males.
That thought was echoed by Dr. Robert Eckel, previous president of the American Coronary heart Affiliation and speedy previous president of medication and science with the American Diabetes Affiliation.
“This trial was not [designed] to evaluate security of testosterone,” he famous, leaving the query of whether or not taking testosterone substitute remedy may really pose a coronary heart danger unanswered.
Nonetheless, Eckel, a professor of medication emeritus on the College of Colorado, mentioned he agrees that “generally, testosterone shouldn’t be given until somebody is hypogonadal,” referring to a situation during which the intercourse glands cease producing sufficient intercourse hormones.
As to the potential coronary heart well being advantages of train, Eckel mentioned there are “no surprises right here. Train is useful… [and] needs to be promoted.”
Yeap and his colleagues reported their findings Feb. 22 within the journal Hypertension.
