Comparison of Pilates and TRX exercise training on serum Spexin levels in overweight women

Spexin is a new peptide that plays a role in regulating the behavior of nutrition, weight, energy metabolism and fatty acid harvesting into fat cells. The aim of this study was to compare the two types of Pilates and TRX exercises on serum spexin levels in overweight women. this was a quasi-experimental study with pretest-posttest design. For this purpose, ۳۳ overweight female dada subjects aged ۲۵-۳۳ years and their BMI above ۲۵ kg/m۲ were randomly selected and divided into ۳ groups of ۱۳, Pilates (experimental ۱), TRX (experimental ۲) and control. The experimental group ۱ exercises included Pilates ۵ -%۳۷ of maximum heart rate for ۸ weeks, ۳ sessions per week, ۶۳ minutes persession, and experimental group ۲ to TRX training with intensity of ۵۳-%۳۷ ۱RM (one repetition maximum) for ۸ weeks and ۳ sessions per week and ۶۳ minutes per session. ۲۴ hours before the first training session and ۴۸ hours after the last session, sampling was performed and anthropometric measurements including height, weight, WHR and BMI and blood samples were taken to assess the biochemical factors of spexin, insulin, insulin resistance, fasting glucose and fasting insulin. Paired t-test and mixed anova were used to analyze the data and bonferroni post hoc test was used to analyze the differences between the groups. The results showed that serum spexin and body composition levels decreased significantly in experimental groups ۱ and ۲ (P≤۳۰۳۵). Blood glucose decreased significantly in experimental group ۱ (P≤۳۰۳۵ ). Insulin and insulin resistance index significantly increased in experimental groups ۱ and ۲ and control group (P≤۳۰۳۵). Blood glucose increased significantly in experimental group ۲ (P≤۳۰۳۵).According to the results of this study, it can be stated with caution that Pilates and TRX training can both reduce spexin levels in inactive obese women and this can be used as a factor for weight loss and fat loss and BMI reduction in these people.
