Effect of Spirulina platensis green-blue algae consumption, and circuit resistance training (CRT) on lipid profile in overweight and obese middle-aged men

Abstract

Background and Aims: Researchers have recently considered the impact of herbal supplements combined with exercise on weight control. This study aimed to investigate the effect of Spirulina platensis green-blue algae consumption, and circuit resistance training (CRT) on lipid profile in overweight and obese middle-aged men. Materials and Methods: This was a single-blind, quasi-experimental, and applied study. The study population included 60 overweight and obese men in the age range of 30-55 years with a body mass index of more than 25 (kg/m2). The participants were purposefully selected and randomly divided into four groups of training plus spirulina (N=15); training plus placebo; spirulina; and Placebo. The intervention and placebo groups took two 500 mg spirulina capsules, and placebo capsules daily for eight weeks, respectively. The CRT was performed for eight weeks and three sessions per week based on a flexible timing pattern, with the observation of the principle of overload with rest intervals between stations and sets. Results: There was a significant difference between the study groups in terms of the levels of triglyceride (TG), high-density lipoprotein (HDL) of the participants (P<0.05). Moreover, in the intra-group investigation, there was a significant reduction in the values of low-density lipoprotein (LDL), and triglyceride (TG), in the groups of training plus spirulina and training plus placebo, cholesterol (TC), and (Aspartate aminotransferase) AST in the groups of training plus spirulina had a significant decrease, Moreover, a significant increase was observed in the levels of HDL and alanine aminotransferase (ALT) in the group of training plus spirulina. Conclusion: It seems that the consumption of Spirulina platensis green-blue algae combined with CRT can be effective in controlling weight and obesity and preventing obesity-related diseases through the improvement of some indices of metabolic profile and body composition.
