the concurrent effect of conjugated linoleic acid supplementation and resistance training on body composition, serum leptin and muscle strength in non-athlete men

چکیده
animal studies have reported very useful properties including weight loss and improved body composition for conjugated linoleic acid (cla). however, there is limited information about the combined effect of resistance training and cla supplementation. therefore, the effect of cla supplementation and resistance training on body composition, serum leptin and muscle strength in non-athlete men was examined in this study. in a quasi-experimental trial with double-blind design, 23 non-athlete men were randomly assigned to two groups: training + supplement (n=11), and training + placebo (n=12). both groups performed 6 weeks (3 sessions per week) of resistance training program based on the kramer (2004) protocol. the experimental group received 3 capsules (1000 mg) of cla supplement and the control group ingested 3 capsules of placebo (olive oil) per day. muscular strength, body composition and serum leptin were measured in the beginning and at the end of the study. data were analyzed using dependent and independent t tests. based on the findings, cla + resistance training supplementation significantly decreased fat mass and serum leptin and significantly increased non-fat mass compared with placebo + resistance training (p˂0.05) while the lower and upper body strength of both groups were not significantly different. according to the results, it can be stated that resistance training combined with cla supplementation can improve body composition and decrease serum leptin in non-athlete men. but it does not necessarily lead to a significant improvement in lower and upper body strength.

Conjugated linoleic acids (CLA) are essential fatty acids that have been reported in animal studies to decrease catabolism, promote fat loss, increase bone density, enhance immunity, and serve as an antiatherogenic and anticarcinogenic agent. For this reason, CLA has been marketed as a supplement to promote weight loss and general health. CLA has also been heavily marketed to resistance-trained...

15 صفحه اولThe Effect of Conjugated Linoleic Acid supplementation on the Serum Leptin Level, Pulmonary Function and Quality of Life in COPD Patients
Background & objectives: Chronic Obstructive Pulmonary Disease (COPD) is accompanied by systemic inflammations and is characterized by irreversible airflow limitations. Leptin is a cytokine with pre-inflammatory effect. However, there have been no studies on the effect of conjugated linoleic acid (CLA) on the serum leptin concentration in COPD patients. Therefore, the present study aimed to e...
