Abstract
A positive affective experience, making exercise more pleasurable, less stressful, achieving greater satisfaction and intrinsic motivation experience through resistance training may be accomplished by performing self-selected exercises. These exercises can also lead to other health-related and performance outcomes. Thus, this study aimed to analyze the effects of a short-term self-selected resistance training on levels of anxiety and depression in sedentary individuals. Twenty-one individuals, aged between 20 and 50 years, were assigned to Training Group (TG) and Control Group (CG). The TG underwent 4 weeks of resistance training, 2 sessions per week, with self-selected intensities. Anxiety and depression scores were collected before and after intervention using the Hospital Anxiety and Depression Scale (HAD). The results showed that the TG presented a significant reduction in anxiety scores (8.9±2.0 to 7.1±2.1; p=0.008) with a large effect size (d=0.71). Depression scores showed no significant difference after intervention (6.3±2.6 to 5.4±2.6; p=0.094), with a small effect size (d=0.346). The CG showed slight non-significant increase in depression scores (6.3±3.1 to 6.8±3.7; p=0.297), with small effect size (d= 0.146). In conclusion, resistance training with self-selected intensity reduced anxiety scores and kept depression scores in a healthy level in sedentary individuals.
Highlights
Depression and anxiety affect over 300 million and 264 million people worldwide, respectively (WHO, 2017)
The results showed that the Training Group (TG) presented a significant reduction in anxiety scores (8.9±2.0 to 7.1±2.1; p=0.008) with a large effect size (d=0.71)
The sample was initially composed of 26 individuals, randomly assigned to control group (CG) or training group (TG)
Summary
Depression and anxiety affect over 300 million and 264 million people worldwide, respectively (WHO, 2017). Depression has an incidence elevation of 18.4% in ten years, whereas anxiety has 3.6%. Brazil ranks first with the highest prevalence of anxiety in the world with approximately 18.7 million people, representing 9.3% of the entire population, Research, Society and Development, v. To the best of our knowledge, there are no studies that investigated the effects of SSRT on anxiety and depression scores, regardless of the population. This study aimed to verify the effects of self-selected resistance training on anxiety and depression scores in sedentary individuals
