Voluntary wheel running promotes resilience to the behavioral effects of unpredictable chronic mild stress in male and female mice.
Besides significant benefits to physical health, exercise promotes mental health, reduces symptoms of mental illness, and enhances psychological development. Exercise can offset the impact of chronic stress, which is a major precursor to the development of mental disorders. The effects of exercise on chronic stress-induced behaviors are contradictory in preclinical studies, primarily due to the lack of data and sex-specific investigations. We sought to evaluate the effects of exercise on chronic stress-induced behavioral changes in both male and female mice. Mice were subjected to an Unpredictable Chronic Mild Stress (UCMS) paradigm with accessibility to running wheels for 2 h daily. Physiological and behavioral evaluations were conducted throughout the stress paradigm to determine if exercise blunts the effects of UCMS. Chronic stress induced voluntary wheel running (VWR) and weight loss in male and female mice. Compared to males, increased VWR was reported in females who also regained their weight lost by the end of the UCMS protocol. Exercise promoted resilience to stress-induced hyponeophagia in the novelty-suppressed feeding test and increased sucrose consumption. Exercise induced a sex-specific reduction in immobility and avoidance behavior in the tail suspension and open field tests and increased exploratory behavior in the light-dark test. These results indicate that exercise can promote resilience to the behavioral effects of chronic stress in males and females, and can affect behavior independent of chronic stress.
期刊介绍:
The journal Stress aims to provide scientists involved in stress research with the possibility of reading a more integrated view of the field. Peer reviewed papers, invited reviews and short communications will deal with interdisciplinary aspects of stress in terms of: the mechanisms of stressful stimulation, including within and between individuals; the physiological and behavioural responses to stress, and their regulation, in both the short and long term; adaptive mechanisms, coping strategies and the pathological consequences of stress.
Stress will publish the latest developments in physiology, neurobiology, molecular biology, genetics research, immunology, and behavioural studies as they impact on the understanding of stress and its adverse consequences and their amelioration.
Specific approaches may include transgenic/knockout animals, developmental/programming studies, electrophysiology, histochemistry, neurochemistry, neuropharmacology, neuroanatomy, neuroimaging, endocrinology, autonomic physiology, immunology, chronic pain, ethological and other behavioural studies and clinical measures.
