Along with drug interventions, physical activity (PA) was found to be beneficial to treat a wide range of mental pathology (e.g., depression, mood disorders). However, in the case of anxiety disorder (AD) treatment, studies reported inconsistent findings depending on the exercise type (e.g., acute or chronic exercise, aerobic or anaerobic exercise) among clinical and non-clinical population. The purpose of this article is to present a systematic review about the moderating role of exercise type in AD among clinical and non-clinical population. Searches included SPORTDiscus, PubMed, Google Scholar databases. Eighteen full text articles were retained for the review, because they were written in English and published within the last five years. The review reported the moderating effect of PA on AD, in the sense that chronic (endurance) exercise appeared to be more beneficial for reducing AD than acute bouts of exercise, and that moderate aerobic exercise reduced AD effectively. Also, relaxation and mediation exercise (e.g., yoga) appeared to reduce AD. According to the scientific literature, PA appears of interest to treat AD. Further studies are necessary to examine in depth the relationship between PA and AD.

Decline in cognitive function leads to several diseases and impairments. Findings from literature explain that exercise training may reduce the negative effects and enhance cognition. The review aims to present aerobic and resistance exercise training programs with the most beneficial outcomes regarding enhancement of cognitive function and related diseases. Electronic literature of SPORTDiscus, PubMed, and Google Scholar databases in English language between 2003 and 2015 was used to search for cognitive function in relation to exercise training. A total of 99 abstracts were examined; 43 abstracts were excluded for using animal subjects, derivative data, and languages other than English. A total of 56 articles were fully read; 11 of those were excluded due to lack of evidence, to reach a narrowed outcome. Outcomes indicate that aerobic exercise has more benefits on cognitive function rather than resistance training (e.g. enhancing memory, learning, cognitive speed). On the other hand, combined resistance and aerobic training has better results than aerobic training alone. In addition, exercise training is not only beneficial on cognitive function, but also reduces and prevents related cognitive diseases such as Alzheimer's disease and Cushing's syndrome. Several studies have indicated that aerobic exercise training improves cognitive function as well as reduces related cognitive diseases. Further studies are necessary in order to attain sufficient evidence and neglect the conflict regarding the effect of resistance exercise training on cognitive function.
