The Effects of Simultaneous Interventions of Caffeine and Aerobic Training on Leptin-To-Adiponectin Ratio (LAR) In Type 2 Diabetic Men

Imbalanced production of adipokines as leptin and adiponectin in diabetic patients may lead to the development of metabolic complications. Therefore, the aim of this study was to determine the effects of 2-month of caffeine ingestion along with aerobic training on changes in serum leptin and adiponectin levels and leptin/adiponectin ratio (LAR) in type 2 diabetic men.

Thirty-two diabetic men participated in a quasi-experimental designs in the four groups for two-months period of a aerobic training (treadmill walking 3 times/week, 1.5 hour/session, 65-85% HRR) with and without caffeine ingestion (3 mg.kg-1.day). Serum changes in leptin and adiponectin were measured during two phases (baseline and 24-hours after completing of the training program). Data were analyzed by one-way ANOVA and bonferroni's post-hoc test at level P≤0.05.

Administration of two-months caffeine (CA) alone and combination with aerobic training (AT) were significantly could reduced and increased in leptin and adiponectin level, respectively (P=0.001). Thus, the combined group (AT+CA) effect were far more appropriate intervention in changing the studied indices (P=0.001). Also, the LAR method was notable reduced in all study groups, although these effects were more significantly in the combined group (AT+CA) (P=0.001).

It seems administration of caffeine supplementation and aerobic training for two-months have a positive effects on the improved relative of leptin and adiponectin levels as well as their ratio in diabetics, although the combination of these two variables has been shown to have far more dual effects.
