Abstract
Generalized anxiety disorder (GAD) is a prevalent mental health condition affecting a significant proportion of the adult population. Despite the availability of pharmacological treatments, their long-term efficacy and potential side effects necessitate exploring alternative interventions. Aerobic exercise has emerged as a promising non-pharmacological approach for managing anxiety symptoms in individuals with GAD. This narrative review examines the efficacy of aerobic exercise interventions in alleviating symptoms of anxiety disorders, drawing on a comprehensive analysis of relevant literature. The review synthesizes findings from studies investigating various forms of aerobic exercise, including high-intensity interval training, resistance training, Pilates, and walking. The results indicate that aerobic exercise interventions demonstrate efficacy in reducing anxiety symptoms and improving overall well-being across diverse populations, including primary care patients, individuals with coronary heart disease, and older adults with cancer undergoing chemotherapy. The review discusses the neurobiological and psychological mechanisms underlying the anxiolytic effects of aerobic exercise. It highlights the implications of these findings for clinical practice, public health initiatives, and future research directions. Despite the promising evidence, limitations in study methodologies and heterogeneity across interventions warrant a cautious interpretation of the results. Further research is needed to elucidate optimal exercise modalities, dosages, and long-term effects on anxiety outcomes.
