Abstract
Insects contain a number of beneficial macronutrients, micronutrients, and bioactive compounds that play crucial roles for optimal bodily functions and exercise. This review aims to consolidate information from studies involving humans and animals that investigated the effect of insect consumption, either alone or in combination with exercise, on exercise performance, body composition, and metabolism. In humans, insect supplementation with exercise could improve strength. Insect supplementation, with or without exercise, could also improve body composition. However, the lack of dietary and physical activity control may have influenced these findings. Insect consumption alone caused increased blood amino acids, followed by activation of the mammalian target of rapamycin complex-1 (mTORC1) signalling and increased muscle protein synthesis, which is further elevated when combined with resistance exercise. In animals, insect consumption alone could improve endurance and fatigue biomarkers. It could also reduce fat mass and increase muscle mass. The reduction in fat mass was attributed to improvements in blood lipid profiles, while the increase in muscle mass is attributed to elevated blood amino acids and mTORC1. Interestingly, in combination with exercise, greater changes in these variables were observed, including increases in energy metabolism. Findings from animal studies, such as changes in muscle mass and protein metabolism, have been validated in humans, while outcomes regarding endurance, fat mass, and blood lipids have not been validated in humans. This encourages future research to focus on these parameters. Due to ethical constraints and impracticality, there has been a reliance on animal studies to elucidate certain mechanisms and parameters in humans. Overall, insect consumption, with or without exercise, in both humans and animals showed promising results in improving exercise performance, body composition, and metabolism and thus, could function as an alternative exercise supplement. Additionally, utilizing animal models has allowed researchers to better understand the key mechanisms behind these improvements.

Abstract
Insects contain a number of beneficial macronutrients, micronutrients, and bioactive compounds that play crucial roles for optimal bodily functions and exercise. This review aims to consolidate information from studies involving humans and animals that investigated the effect of insect consumption, either alone or in combination with exercise, on exercise performance, body composition, and metabolism. In humans, insect supplementation with exercise could improve strength. Insect supplementation, with or without exercise, could also improve body composition. However, the lack of dietary and physical activity control may have influenced these findings. Insect consumption alone caused increased blood amino acids, followed by activation of the mammalian target of rapamycin complex-1 (mTORC1) signalling and increased muscle protein synthesis, which is further elevated when combined with resistance exercise. In animals, insect consumption alone could improve endurance and fatigue biomarkers. It could also reduce fat mass and increase muscle mass. The reduction in fat mass was attributed to improvements in blood lipid profiles, while the increase in muscle mass is attributed to elevated blood amino acids and mTORC1. Interestingly, in combination with exercise, greater changes in these variables were observed, including increases in energy metabolism. Findings from animal studies, such as changes in muscle mass and protein metabolism, have been validated in humans, while outcomes regarding endurance, fat mass, and blood lipids have not been validated in humans. This encourages future research to focus on these parameters. Due to ethical constraints and impracticality, there has been a reliance on animal studies to elucidate certain mechanisms and parameters in humans. Overall, insect consumption, with or without exercise, in both humans and animals showed promising results in improving exercise performance, body composition, and metabolism and thus, could function as an alternative exercise supplement. Additionally, utilizing animal models has allowed researchers to better understand the key mechanisms behind these improvements.
