Am J Physiol Gastrointest Liver Physiol
August 2025
Host-gut microbiota interactions may impact intestinal function during sustained periods of high energy demands. Whether energy status, reflecting the balance between energy intake and expenditure, impacts those interactions is unknown. This study determined the effects of energy status during sustained high-energy demands on intestinal function and the gut microbiota.

- Open goals, such as aiming to increase daily steps, have been found to encourage physical activity and positive experiences compared to specific targets like 10,000 steps.
- A study tested the feasibility of an open-goal approach over 10 weeks with 15 adults, focusing on factors like recruitment and adherence, and found high participation along with increased physical activity levels.
- Results suggested that open goals enhance enjoyment and self-efficacy while reducing negative feelings, demonstrating their potential for use in longer-term physical activity programs.
The SMART acronym (e.g., Specific, Measurable, Achievable, Realistic, Timebound) is a highly prominent strategy for setting physical activity goals.

- Polybrominated diphenyl ethers (PBDEs) like BDE-47 are used as flame retardants but are harmful environmental pollutants affecting human health.
- This study examined the toxic effects of BDE-47 on PC12 nerve-like cells, finding that it disrupts mitochondrial respiration and increases glycolysis, while reducing important metabolites in energy metabolism.
- The research identified 17 metabolic changes potentially linked to BDE-47’s neurotoxicity, suggesting future therapeutic strategies could focus on protecting mitochondrial function and glycolysis.
Updating goal-setting theory in physical activity promotion: a critical conceptual review.
Health Psychol Rev
March 2021
Goal-setting is a widely used and accepted strategy for promoting physical activity. Locke and Latham's goal-setting theory is the primary theoretical framework for setting goals in psychology and plays a prominent role in physical activity promotion. Recently, however, there have been calls to reconsider current goal-setting practice in this field.
