Background: In the recent years, interest to the assessment of medicinal plants on the protection of body has emerged. The aim of this study was to investigate the effect of high intensity interval training (HIIT) along with consumption caraway seeds on liver enzymes, lipid profile and blood glucose in obese and overweight women.
Materials and methods: In this semi-experimental study, 24 women aged 25 to 35 years were selected and randomly divided into three obese, overweight, and control groups. All groups consumed caraway seeds (powder), 50 mg/kg twice a day for six weeks. The test group performed three HIIT sessions per week for six weeks. Each session consisted of four to six repeats of maximal sprint running (90-95% of maximum heartbeat) within a 20m area with 60s recovery gaps. Blood samples were obtained after 12 hours fasting before and after training. Data were analyzed using ANOVA with repeated measure for assessment of time interactive effect (consisting of two levels, i.e. before and after training) on the studied groups in the applied amounts of the desired variables.
Results: The results of the current study showed that the three groups have significant differences in term of triglyceride (p=0.043) and AST (p=0.005) factors, but no significant difference was observed in the other variables (FBS, cholesterol, ALT, ALP, and ALT/AST) between the groups.
Conclusion: According to the results of this study, it seems that HIIT with consumption of caraway seeds can be useful in prevention from the occurrence of some diseases associated with obesity; however, to achieve the desired results, the intervention should be longer.

Background and aims: Non-alcoholic fatty liver disease (NAFLD) is a chronic liver condition that is associated with the changes in transferase enzymes and atherogenic parameters. The aim of this study was to evaluate the effect of eight weeks of high-intensity interval training (HIIT) on plasma levels of liver enzymes and atherogenic markers in NAFLD patients.
Methods: In this quasi-experimental study 25 women with NAFLD were randomly selected and allocated to exercise (n=13) and control (n=12) groups. HIIT protocol with an intensity of 80-85% of maximum heart rate was performed for eight weeks, four sessions in a week and 60 minutes in each session (15min warm-up, 30min training exercises, and 15min cooling down). The plasma levels of liver enzymes and atherogenic markers were compared before and after the protocol.
Results: After eight weeks of HIIT, in both the intergroup and the intragroup comparisons, a significant increase was detected in plasma levels of HDL-cholesterol. Additionally, in both intergroup and intragroup comparisons, a significant decreases was observed in plasma levels of triglycerides, TC (total cholesterol), LDL-cholesterol, and ALT, as well as LDL/HDL, lipid accumulation product (LAP) index, atherogenic index of plasma (AIP), TC/HDL, body fat percentage, and body mass index (p<0.05). It should be noted that despite a decrease in the plasma levels of AST compared to the pre-test and control group, it was not statistically significant.
Conclusion: According to the findings of this study, HIIT can be suggested as a treatment and prevention strategy for NAFLD.

Background and aims: Due to the high prevalence of obesity and fatty liver disease caused by obesity, it is necessary to find an effective and useful solution. Therefore, the aim of this study was to examine the effect of 12 weeks of TRX training on fatty liver enzymes in obese and overweight female.
Methods: Totally, 30 overweight and obese female (BMI=33.24±4.7) who had no history of exercise or certain diseases were selected as a purposive sampling. Then, they were randomly divided into two groups of TRX training (n=15) and control (n=15). The training protocol included resistance training in the form of TRX suspension training, which was performed three days a week on non-consecutive days for 12 weeks, and each session lasted 60 minutes. Body weight, height and levels of liver function tests (LFTs) along with hepatic steatosis index (HSI) were measured 48 hours before and after the training period.
Results: It was found that body weight (p=0.001) and BMI (p=0.001) in the exercise group decreased significantly compared to the control group. However, there was no statistically significant difference between the two groups in the serum levels of LFTs as well as HSI.
Conclusion: It seems that although TRX resistance training for 12 weeks has a beneficial effect on improving body weight and BMI, this training intervention has no effect on LFTs and HSI in overweight and obese women.
