Effects of a Single Bout of Aerobic Exercise Versus Resistance Training on Cognitive Vulnerabilities for Anxiety Disorders

Abstract

The purpose of this study was to compare the relative effects of a single bout of aerobic exercise versus resistance training on cognitive vulnerabilities for anxiety disorders. Seventy-seven participants (60% female; 84% Caucasian) were randomized to complete 20 min of moderate-intensity aerobic exercise, resistance training, or rest, followed by a 35% CO2/65% O2 inhalation challenge task. Results indicated that aerobic exercise and resistance training were significantly and equally effective in reducing anxiety sensitivity (AS) compared with rest ((η(2)(p ) = 52), though only aerobic exercise significantly attenuated reactivity to the CO2 challenge task. Neither form of exercise generated observable effects on distress tolerance, discomfort intolerance, or state anxiety (all ps >.10). The results of this study are discussed with regard to their implications for the use of exercise interventions for anxiety and related forms of psychopathology, and potential directions for future research are discussed.

Exercise as a prescription for patients with various diseases

“…For the patients with an anxiety disorder, RE was performed at low to high intensity acutely or for a short term with a frequency of 2 times per week. So, RE was a low-risk and feasible method to reduce anxiety symptoms in patients with general anxiety disorder 191, 192…”

Exercise for Mood and Anxiety Disorders: The State-of-the Science

“…Broman-Fulks, Kelso, and Zawilinski (this issue) randomized 77 healthy participants to a single bout of 20 minutes of aerobic exercise, resistance training, or rest followed by a 35% CO2 inhalation. Results showed that both exercise conditions reduced AS; but, only aerobic exercise reduced CO2 anxious responding.…”

Exercise-related Mental Health Problems and Solutions during the COVID-19 Pandemic

“…A 2015 study on anxiety state after aerobic and resistance training showed significant decrease in anxiety sensitivityoverreacting to sensations that accompany anxietywith both forms of training. Other markers of anxiety, such as severity of anxiety after a 35% CO 2 breathing challenge test and intolerance of uncertainty, were either reduced only by aerobic exercise or not reduced by either form of exercise (2). These two studies support that people like Ms. O could be adversely affected by the altered exercise conditions of the pandemic.…”
