Abstract

PURPOSE The purpose of this study was to examine the effects of an acute bout of yoga exercise on the secretion of growth hormone (GH) in healthy, young males and females. METHODS Seventeen participants (mean age 23.9 ± 3.9) were volunteered and completed the university IRB approved study. Participants completed a 60-min, certified instructor led yoga session. Blood (5ml) was collected at rest, 10-min prior (PRE), at the 35-min point during (MID), and immediately post (POST) the yoga session. Serum GH was measured using immunochemiluminometric assay. Resting GH levels were statistically compared to mid- and post-yoga GH levels using a repeated measure ANOVA. RESULTS Significant increases in GH were seen 35-min into the yoga session (PPCONCULSION The release of GH into the blood during yoga may partially explain the physiological mechanisms underlying the health benefits of this low impact activity.
