The effects of coconut oil supplementation on the body composition and lipid profile of rats submitted to physical exercise

Abstract

This study aims to verify the effects of coconut oil supplementation (COS) in the body composition and lipid profi le of rats submitted to physical exercise. The animals (n=6 per group) were randomly assigned to: G1=Sedentary and Non-supplemented (Control Group), G2=Sedentary and Supplemented, G3=Exercised and Non-supplemented and G4=Exercised and Supplemented. The COS protocol used was 3 mL/Kg of body mass by gavage for 28 days. The physical exercise was the vertical jumping training for 28 days. It was determined the body mass parameters, Lee Index, blood glucose and lipid profi le. The COS did not interfere with body mass, but the lean body mass was lower in G3 compared to G2. The fi nal Lee Index classifi ed G1 and G2 as obese (>30g/cm). The lipid profi le showed total cholesterol was decreased in G3, LDL-c concentration was decreased in G2, triglycerides, VLDL-c and HDL-c concentrations were increased in G2 and G4 in relation to G1 and G3. The COS decreased LDL-c/HDL-c ratio. In conclusion, the COS associated or not to physical exercise worsen others lipid parameters, like triglycerides and VLDL-c level, showing the care with the use of lipid supplements.

Unconnected Body Accrual of Dietary Lipid and Protein in Rats Fed Diets with Different Lipid and Protein Content

“…[11,31] In this work, the ingestion of a diet enriched with mainly saturated fats (coconut oil), containing a fat percentage ten times higher than that of the standard diet, did not cause per se an increase in the amount of energy ingested or significant variations in body weight (compared with controls fed the SD diet) during the period studied. This fact is consistent with previous data [32] and might be explained in part by the presence of lauric acid, which has been found to decrease food intake. [33,34] These results, however, contrast with the effects elicited by high-carbohydrate or cafeteria diets [35] containing comparable proportions of energy derived from lipids, which have been reported to markedly increase weight, especially that of adipose tissue.…”

Capsaicinoids improve consequences of physical activity

“…In the present study, we demonstrated for the first time that combination of regular exercise and CAPs intake significantly reduced the levels of muscle SREBP-1c, LXRs, ACLY, and FAS transcriptional regulators that induce key lipogenic enzymes to promote lipogenesis. Similarly, previous studies have shown that physical exercise has a better lipidic profile compared to sedentary ones such as higher HDL-c and lower LDL-c and VLDL-c, and capsaicinoid consumption also positively affects the expression of lipogenic genes in adipose tissue [ 34 , 38 , 63 ]. Nevertheless, it has been reported that liver mRNA expression of FAS decreased and the expression levels of hormone-sensitive triglyceride lipase increased by capsaicin and paprika seed oil in rats [ 64 ].…”

Acute Caffeine and Coconut Oil Intake, Isolated or Combined, Does Not Improve Running Times of Recreational Runners: A Randomized, Placebo-Controlled and Crossover Study

“…Additionally, young adults that consume CO do not experience a change in total plasma antioxidant capacity following a bout of moderate-intensity cycling exercise [15] Likewise, it was found in rats that CO supplementation, with or without exercise, enhanced blood triacylglycerol and VLDL-c concentrations [31]. Therefore, lipid supplements did not seem to be a healthy option.…”
