Introduction: Obesity and overweight are among the most serious health challenges in the world. The aim of this study was to determine the effect of a CrossFit training course on the body composition and mental health of overweight women.
Materials & Methods: This quasi-experimental study was carried out on all women aged 25-35 years with body mass indices between 25 and 29.9 kg/m² in Ilam city. 20 people were selected purposively and divided into 2 groups (10 people in each group) by a simple random method, including control (I) and CrossFit training (II). The study involved participants in both groups who completed the Oxford Happiness Questionnaire before and after exercises, and their body composition indices were measured using a body composition analysis device, and a paired t-test was used to analyze the results in SPSS V.23 at p less than 0.05.
Results: CrossFit training did not cause a significant change in body mass index (BMI) and visceral fat index (VFI) (P=0.261 and P=0.114, respectively). CrossFit training also caused a significant increase in the total muscle percentage index (MR) and a significant decrease in the body fat percentage index (BFR) (P=0.001 and P=0.001, respectively). In addition, CrossFit training caused a significant increase in the happiness index of the subjects in the training group compared to the control group (P=0.001).
Conclusion: Physical activation through CrossFit exercises is associated with increased enthusiasm and excitement, increases the level of arousal and vitality, improves body composition, and increases the happiness index in overweight women.
