Effects of Acute Exercise on Affect, Anxiety, and Self-Esteem in Poly-Substance Dependent Inpatients.

INTRODUCTION: Negative affect and anxiety frequently precede the onset of drug use in those with substance use disorder (SUD). Low self-esteem may increase the risk of relapse. We examined the short-term effects of exercise on affect, anxiety, and self-esteem in inpatients with poly-SUD. METHODS: This is a multicenter randomized control trial (RCT) with a crossover design. Thirty-eight inpatients (37.3 ± 6.4 years; 84% male) from three clinics participated in 45 min of soccer, circuit training, and control condition (psychoeducation) in a random order. Positive and negative affect (PANAS), state anxiety (single item), and self-esteem (Rosenberg SE-scale) were measured immediately before, immediately after, 1-h, 2-h, and 4-h post-exercise. Heart rate and ratings of perceived exertion were taken. Effects were assessed using linear mixed effects models. RESULTS: Compared to the control condition, there were significant post-exercise improvements in positive affect (ß = 2.99, CI = 0.39: 5.58), self-esteem (ß = 1.84, CI = 0.49: 3.20), and anxiety (ß = -0.69, CI = -1.34: -0.04) after circuit training (shown) and soccer. Effects persisted 4-h post-exercise. Reductions in negative affect were observed 2-h (circuit training: ß = -3.39, CI = -6.35: -1.51) and 4-h (soccer: ß = -3.71, CI = -6.03: -1.39) post-exercise, respectively. CONCLUSION: Moderately strenuous exercise undertaken in naturalistic settings may improve mental health symptoms in poly-SUD inpatients for up to 4-h post-exercise.

Effects of Acute Exercise on Drug Craving, Self-Esteem, Mood, and Affect in Adults with Polysubstance Use Disorder: Protocol for a Multicenter Randomized Controlled Trial.

BACKGROUND: Novel treatments for substance use disorders are needed. Acute bouts of exercise can improve mood states and craving in nonclinical populations. Exercise effects in those with polysubstance dependence are understudied; controlled trials are needed. OBJECTIVE: This protocol describes a clinical study examining the short-term psychological effects of 2 types of physical activity, soccer and circuit training, in patients with substance use disorders. Effects will be compared with a nonexercise control group. Specific aims are to investigate whether there are differences between the activities and the duration of changes. METHODS: This study is a short-term multicenter randomized control trial with a crossover design. Patients consecutively admitted to 4 inpatient treatment centers were invited to participate in 3 conditions, each lasting 45 minutes, within one week. The order of the conditions was randomized. There were a total of 5 assessments, taken at baseline, immediately before each condition, immediately after each condition, and 1, 2, and 4 hours postintervention, enabling patterns of change over time to be observed. Psychological effects were assessed with self-report questionnaires, which included scales for craving, state anxiety, positive and negative affect, self-esteem, and mood. Exercise intensity was assessed with the Borg Rating of Perceived Exertion scale and a heart rate monitor (Polar M200; Polar Electro Ltd). Cortisol was assessed in saliva before and 4 hours after the intervention. RESULTS: A total of 39 patients were included in the study. Data collection was completed in 2019. CONCLUSIONS: We anticipate larger improvements in the intervention groups than among controls, indicating positive psychological effects during and after exercise. The study will add clinically relevant information about the short-term psychological effects of exercise in the treatment of substance use disorders, using activities that are easily accessible in different clinical settings.

Effects of acute exercise on drug craving, self-esteem, mood and affect in adults with poly-substance dependence: Feasibility and preliminary findings.

INTRODUCTION AND AIMS: Novel treatments for substance use disorders are needed. Acute bouts of exercise can improve mood states in non-clinical populations, but effects in those with poly-substance dependence are understudied. We examined the feasibility and short-term effects of three types of exercise on drug cravings, self-esteem, mood and positive/negative affect in nine poly-drug-dependent inpatients. DESIGN AND METHODS: Using a cross-over design, changes in the four study outcomes were assessed immediately before exercise and on four separate occasions post-exercise (immediately after, then at 1, 2 and 4 h post-exercise) enabling patterns of change over time (analysis of covariance) to be observed. RESULTS: Participants were willing and able to engage in different non-laboratory based exercises. Football was associated with non-significant short-term reductions in drug cravings. A similar trend was seen for circuit-training, but not walking. Football and circuit-training were associated with brief improvements in mood and positive/negative affect. No adverse events were reported. DISCUSSION AND CONCLUSIONS: Football, circuit training and walking are feasible therapeutic activities for inpatients with poly-substance dependence. Controlled trials are needed to determine the long-term effects of these activities.
