Abstract
Background: Insufficiency of omentin-1 and 25-hydroxyvitamin D serum levels is associated with obesity, which is known as a threat to health. Therefore, the aim of the present study was to examine the effect of eight weeks of Pilates exercise on the serum levels of 25-hydroxyvitamin D, omentin-1, and lipid profile in overweight women.
Methods: In the present clinical study, 26 young overweight women were divided (block randomization method) into the Pilates exercise (PT, n= 13) and control group (CG, n= 13). The PT group performed Pilates exercises for eight weeks (three 60-min sessions per week). The movements started from simple and then increased in intensity and complexity based on the Borg index. The CG group had no training session for eight weeks. Blood samples were taken before the first training session and 48 hours after the last training session. Analysis of covariance was used for between-group comparisons.
Results: Findings showed a significant increase in the serum levels of 25-hydroxyvitamin D (p=0.008, SD= 4.78±0.12 ng/ml, effect size= 0.243) and HDL-C (p=0.04, SD= 6.44±1.05 mg/dl, effect size= 0.168), but a significant decrease in HOMA-IR (p=0.001, SD= 1.54±0.09, effect size=0.199), cholesterol (p=0.001, SD= 16.72±3.24 mg/dl, effect size= 0.326), and triglyceride (p=0.001, SD= 2.46±0.07 mg/dl, effect size= 0.209), and no significant change in omentin-1 (p=0.65, SD= 3.01±0.08 ng/ml) and LDL-C (p=0.58, SD= 2.46±0.07 mg/dl) serum levels in the PT group compared to the CG group.
Conclusion: It seems that this type of exercise training may play a critical role in controlling the health parameters and physiological status of the overweight women by having positive effects on serum levels of 25-hydroxyvitamin D and lipid profile, which are affected by body composition, weight, and fat.

Abstract
Background: Factors such as body circumference and body shape indices are better predictors of metabolic risk than traditional anthropometric measures. Regular exercise interventions may improve body composition and lipid profiles. Therefore, the present study aimed to compare the effects of eight weeks of CrossFit training and traditional resistance training on the novel abdominal obesity indices A Body Shape Index (ABSI) and Body Roundness Index (BRI), lipid profile, and physical fitness in obese women with hyperlipidemia.
Methods: This randomized, parallel-group intervention study was conducted among 29 women with obesity (BMI ≥30 kg/m², age 20–30 years) who were randomly assigned to either the CrossFit group (n=15) or the traditional resistance training group (n=14).
Interventions were performed for eight weeks, with three sessions per week. Anthropometric indices, lipid profile, maximal oxygen consumption (VO₂max), and muscular strength were assessed before and 48 hours after the intervention. Data were analyzed using ANCOVA and paired t-tests (α=0.05).
Results: CrossFit significantly reduced waist circumference (P-Value =0.011) and ABSI (P-Value =0.048) compared with traditional training in between-group ANCOVA analyses. Significant between-group differences were observed for HDL (P-Value =0.048), LDL (P-Value =0.007), triglycerides (P-Value =0.041), CHD risk ratio (P-Value =0.018), and atherogenic index (P-Value =0.041), favoring the CrossFit group. VO₂max (P-Value =0.021) and upper-body strength (P-Value =0.001) also improved significantly in the CrossFit group. However, lower-body strength did not differ significantly between the groups (P-Value =0.289).
Conclusion: CrossFit training may be more effective than traditional resistance training for improving lipid profile, abdominal obesity indices, and aerobic capacity in obese women with hyperlipidemia. However, larger studies are required to confirm these findings.
