Impact of weekly resistance training set volume on adiponectin, TNF-ALFA and leptin levels in obese individuals: a systematic review

Abstract

This literature review study aimed to investigate the impact of different weekly set volumes of resistance training on the levels of adiponectin, TNF-alpha, and leptin, cytokines related to lipoinflammation in obese individuals. The search was carried out in the PubMed and Scielo databases, with a time window of 10 years. The following descriptors were used in the search for articles: (Strength Training OR resistance training OR Strength exercise) AND Leptin AND obesity; (Strength Training OR resistance training OR Strength exercise) AND TNF-alpha AND obesity; (Strength Training OR resistance training OR Strength exercise) AND adiponectin AND obesity. A total of 8 studies were selected and analyzed according to the inclusion criteria. The results revealed that resistance training with higher volumes of weekly sets was more effective in reducing the concentrations of leptin and TNF-α, however, this same pattern did not positively or negatively influence the levels of basal concentrations of adiponectin. Thus, it seems that in obese individuals, greater volumes of weekly sets of resistance training can influence the reduction in the inflammatory environment, mainly reducing TNF-α and Leptin.
