The Effect of Bitter Orange Peel Compounds and Physical Activity on Physical Performance and Health

The purpose of this research is to investigate the effect of orange peel compounds and physical activity on physical performance and health. The research method was descriptive-analytical, and the results showed that orange peel has attracted the attention of researchers due to its alkaloid compounds, including Synephrine and Octopamine, as one of the effective and widely used plants for physical performance and weight control. By activating β3 adrenergic receptors, synephrine increases lipolysis and the availability of free fatty acids (FFA) to peripheral tissues, especially skeletal muscles, which increases the oxidation process of FFA and reduces the oxidation of carbohydrates. The result of these changes is the preservation of muscle glycogen consumption and the delay of fatigue. On the other hand, synephrine reduces appetite by acting on the neuromedin U2 receptor and causes weight loss simultaneously with the development of thermogenesis. Although the effect of the compounds in orange peel on physical performance and weight control is contradictory, more studies are needed to understand the effects of these compounds.
