Abstract

Background: The current study aims to investigate the impact of high intensity interval training (HIIT) on serum levels of CK and LDH as the muscle damage indicators and on Gelatinase-A (MMP-2) serum levels as the tissae inflammatory marker among young sedentary girls.

Materials and Methods: For this quasi-experimental study, 14 sedentary female college students were selected and randomly divided into two groups including the exercise HIIT group (means and standard deviations of age: 21.28 ± 2.56 (years)  weight:52.86 ±4.95 (kg) and height: 163.1±3.7 (cm)) and the control group (means and standard deviations of age: 20.25 ±7.50 (years) weight:52.64 ±3.67 (kg) and height: 162.4±4.5 (cm)). The experimental group performed six repetitions of one-minute runs at 90%- 95% of HRmax. The blood samples were collected before and 30 minutes after the exercise protocol. The serum CK, LDH and MMP-2 levels were measured using corresponding kits. The data were analyzed through the independent t-test at the significance level of 0.05 (p<0.05).

Results: After collecting and analyzing Data, the results showed that CK and LDH levels increased significantly after performing HIIT, while there was no significant change in MMP-2 due to the HIIT.

Conclusion: It can be concluded that the HIIT protocol will lead to an increase in some indicators of muscle damage such as CK, LDH, and that no significant changes could be observed for MMP-2 as the body's inflammation response.

Abstract

Background: The evidence suggests that obesity causes the chronic inflammation. Chemerin is a new adipokine which is associated with obesity and metabolic syndrome. The effects of combined training on levels of inflammatory markers specialy chemerin and serum amyloid-A has been less studied.The present study aims to examine the effect of six weeks combined training on plasma levels of chemerin, CRP and SAA and plasma lipid in obese men.

Materials and Methods: 18 obese men were divided into control and experimental groups. General characteristics of subjects serum levels of chemerin, CRP and SAA were examined (by ELISA method), before and after one session training. Endurance training protocol was performed on the large muscles included in 6 weeks running around the track with 60 to 75% HRmax, 4 sessions per week, intense resistance training for 25 to 30 minutes with 50 to 70% of one repetition maximum of 6 stations (2 sets, 12 Reps). Data analysis was performed by T-independent test for comparison of two control and training groups, T-paired test for comparison of two groups before and after the test and significant level of p≤0.05 was considered.

Results: The results show that 6 weeks combined training significantly decrease the plasma levels of chemerin (p=0.004), and SAA (p=0.009), but there was not any significant decrease on CRP levels(p=0. 476). So, it can be concluded that combined training will affect on some inflammatory markers in obese men and improve them.

Conclusion: One session combined training for 6 weeks significantly affects on plasma levels of chemerin and serum amyloid-A, however, it doesn't decrease the plasma levels of C-reactive protein (CRP).

Abstract

Background: The aim of this study was to determine the effect of preconception endurance exercise training with voluntary exercise activity during pregnancy in mother mice on lipid profile in adult offsprings.

Materials and Methods: Twenty four C57BL/6 female mice were randomly divided into four subgroups: trained in preconception period and exercised during pregnancy (TE)(20.3±1.02g); trained in preconception periods but unexercised during pregnancy (TC)(21.58±0.4g); untrained in preconception periods but exercised during pregnancy (CE)(21.02±0.23g); untrained and unexercised (CC)(19.23±0.45g). Trained mice were subjected to a protocol of moderate endurance exercise training over a period of 4 weeks for 5 days before pregnancy. The fasting blood samples were collected from adult mice(8 weeks old) and serum levels of glucose and lipid profile were measured. Data were analyzed using two way ANOVA and Tukey’s post hoc test.

Results: The Glucose test results in offspring showed that there was a significant interaction between group and sex and group main effect (p<0.001) Glucose levels of male offspring were significantly lower in TC and TE groups. Results on LDL also showed that the sex main effect was significant (p<0.001), and LDL levels of male born to TE and TC dams lower than in female offspring.

Conclusion: Improving the mother's physical fitness by providing regular endurance training in the preconception period and maintaining it by exercise activty throughout pregnancy may have potential for eliciting positive changes in lipid profile of offspring, specially males.

Abstract

Abstract

Background: Protein tyrosine phosphatase 1B (PTP1B) is a key enzyme in dephosphorylation of the insulin receptor (IR) and it is a central factor to induce the insulin resistance. The purpose of this study was to evaluate the effect of 12-week aerobic training on protein tyrosine phosphatase 1B gene expression and insulin resistance in diabetic rats.

Materials and Methods: In this study, 16 Wistar rats were divided into aerobic training and control groups. After inducing diabetes intra protaneally, aerobic training group performed training protocol for 12 weeks and 5 session/week. The duration and speed of each session increased progressively as 18 to 26 m/min and 10 to 55 min, respectively. Then, blood and tissue (from gastrocnemius) sampling were carried out in diabetic rats. Insulin resistance markers and PTP1B gene expression were evaluated by commercial kits and Real-Time PCR method, respectively.

Results: Findings showed that PTP1B significantly was decreased in diabetic rats of aerobic training group (p=0.0001). Also, glucose and insulin resistance significantly was decreased in aerobic training groups (p=0.02 and p=0.006, respectively). However, insulin in control rats was significantly increased (p=0.015).

Conclusion: It seems that, current aerobic training protocol has capability to decrease PTP1B and insulin resistance in diabetic rats. Furthermore, the direct correlation between PTP1B and insulin illustrated that any changes in insulin resistance due to exercise training associated with diminution of negative regulation of insulin signaling pathway.

Abstract

Background and Aim Adropin is a new hormone plays an important role in improving lipid metabolism and vascular protection. The current study aims to determine the effect of eight weeks of high-intensity interval training (HIIT) on Adropin level and nitric oxide (NO) metabolites in overweight men.
Methods & Materials This is a quasi-experimental study with a pre-test/post-test design. Participants were 32 overweight men (Mean±SD age: 30.5±3.07 years, BMI: 27.93±4.2 kg/m2). They were randomly divided into two groups of HIIT (n=16) and control (n=16). The VO2max test was first conducted. Then, the HIIT group performed 8 weeks of HIIT (3 days per week) at 20 sessions of 30 seconds with a 13-s interval between each session. Body composition was measured using a bioelectrical impedance analyzer and the blood sampling was done for measuring Adropin and NO metabolites by ELISA kits in pre-test and post-test phases. The data analysis was done by repeated-measures ANOVA. The significance level was set at P<0.05. 
Ethical Considerations This study was approved by the ethics committee of the University of Tehran (Code: IR.UT.REC.1395007). All procedures were in accordance with guidelines of the declaration of Helsinki. 
Results There was a significant difference in Adropin between HIIT and control groups (0.88±0.256; 95% CI: 0.26-1.5 ng/mL). There was also a significant difference in NO metabolites between the two groups (7.5±3.03; 95% CI: 0.85-14.15 ng/ml). Moreover, there was a positive relationship between Adropin and NO metabolites in overweight men (r=0.498, P=0.0001).  
Conclusion It seems that HIIT can attenuate cardiovascular diseases by increasing Adropin and NO and can improve cardiovascular fitness (VO2max) and body composition of men with overweight.
