Abstract

Context: Adiponectin is a hormone involved in energy metabolism. However, its response to weight loss achieved through Exercise + Diet as compared to Diet Alone, is not fully understood. In addition, the impact of Exercise and Diet on adiponectin related hormones has not been thoroughly investigated in the specific cohort of men ages 35-55 years of age who are overweight and obese. Objectives: To determine; (1) the influence of 12 weeks of supervised resistance training combined with a hypocaloric macronutrient scheduled diet (Exercise + Diet) on fasting adiponectin in overweight and obese men, (2) the influence of the above modalities on TNF-α, leptin, ghrelin, and testosterone, and (3) the relationship of regional adiposity and body fat topography with these hormones. Design, Setting, Participants: The study was a randomized control trial of fifty-one healthy inactive males (35-55 years old), with a BMI of 25-35 kg/m², in St. John’s NL between August 2011 and August 2014. Intervention: Subjects received either a 12 weeks of Exercise + Diet or a Diet Alone weight loss intervention.
