Obesity is associated with many health problems, including diabetes, hypertension, coronary artery disease, and osteoarthritis. The purpose of this study was to investigate the effect of cinnamon supplementation with resistance training on plasma levels of leptin, adiponectin in overweight women.

Forty overweight women were divided into 4 groups (n=10) including resistance training +cinnamon supplementation, resistance training, cinnamon supplementation and control groups. Experimental group performed resistance exercises for 8 weeks, 3 sessions per week up to 60-80 percent of one repetition maximum. The subjects in the resistance training +cinnamon supplementation and cinnamon supplementation groups, received 7 mg of cinnamon powder per kg of body weight three times a day. Blood samples as serum leptin and adiponectin levels were taken before and also 48 hours after the last exercise session of the protocol. For statistical analysis, the paired t-test and covariance test were used to examine the difference between groups at the significant level of p≤0.05.

The result indicated significant decreases in leptin levels and increases of the adiponectin level in resistance training groups + cinnamon intake (p < 0.001 and p < 0.01 respectively), resistance training group (p < 0.01) and cinnamon supplement (p < 0.01 and p < 0.02 respectively). Moreover, there was no significant differences between the effect of cinnamon supplementation on leptin (p < 0.07) and adiponectin (p < 0.24); but resistance training + cinnamon supplementation showed higher decreasing in leptin (p < 0.01) and more increasing in adiponectin levels (p < 0.01) compared to resistance training and cinnamon supplementation alone.

Regular resistance training along with supplementation of cinnamon can reduces the risk of cardiovascular disease by improving the levels of leptin and adiponectin and it can be used as an effective non-pharmacological treatment to prevent these diseases.

Previous studies have reported conflicting results concerning the association between shift work and variables such as blood pressure and lipid profile.

The present study aimed to examine the moderating effect of shift work on lipid profile and blood pressure.

This cross-sectional study was done on steelworkers who worked in Esfahan’s Mobarakeh Steel Company (EMSC) in the year 2017. In this study, workers were selected using random cluster sampling to investigate the moderating effect of shift work on lipid profile using the path analysis model in AMOS software.

A total of 1549 workers (including 926 (60%) shift workers and 623 (40%) day workers) with a mean age of 24.17 ± 6.11 years participated in this study. The path analysis model showed a good fit index (RMSEA = 0.012, P = 0.010). The path analysis results revealed that shift work moderating effect caused a decrease in the relationship between Triglyceride (TG) and Low-Density Lipoprotein (LDL) and between TG and LDL but increased the relationship between TG and Diastolic Blood Pressure.

Our findings showed a new evidence that shift work could have a moderating effect on blood pressure and lipid profile
