Abstract
Background: Diabetes is considered as one of the health problems in all societies. Exercise training
and drug interventions, especially herbal medicines, consider as approaches to improving diabetes.
The objective of this study was to investigate the effect of 6 weeks of aerobic training and Pistacia
atlantica extract consumption on pancreatic β-cells function in streptozotocin-induced diabetic rats.
Methods: Thirty six male Wistar rats divided into five groups: normal control, diabetic control,
diabetes+aerobic training, diabetes+extract, diabetes+aerobic training+extract. Diabetes was induced
by intra-peritoneal injection of streptozotocin (40mg/kg). Exercise program was include 6 weeks of
aerobic training on a treadmill (5 sessions per week, 40 minutes per session, with a speed of 20m/min
and 5% incline). Extract groups were received Pistacia atlantica extract based on body weight, at the
end of each training session. After 6 weeks of aerobic training and Pistacia atlantica extract
consumption, plasma glucose and insulin levels were measured for determination of β-cells function
(HOMA-B). Data were analyzed via ANOVA, with a significant level P<0.05.
Results: HOMA-B index in diabetic control group was significantly higher than normal control group
(P=0.0001). Also mean of HOMA-B index in diabetes+extract and diabetes+exercise training+extract
groups was significantly lower than diabetic control group (P values 0.003, 0.001 respectively) and
between mean of HOMA-B index in diabetic control group with diabetes+aerobic training group were
observed no significant differences (P=0.052).
Conclusion: The results of this study showed that Pistacia atlantica extract consumption, alone and
along with aerobic training leads to significant improvement in pancreatic β-cells function in diabetic
rats. Also extract consumption along with aerobic training in comparison to training alone has had
greater impact on the improvement of pancreatic β-cells function. It seems that aerobic training along
with the use of specific herbal plants can be considered as a complementary therapy in improvement
of diabetics.

Abstract
Background: This study was conducted to determine the effect of 12 weeks of aerobic training on serum levels of vaspin and glucose homeostasis variables in patients with type 2 diabetes. Methods: In this quasi-experimental study, 20 women with type П diabetes (mean±SD: age 43.30 ±3.02 yr, body mass index 27.089±3.23 kg/m2 and body fat 29.46 ±2.71%) were randomized into experimental (n = 10) and control (n = 10) groups. Experimental group performed twelve weeks aerobic training (3 times per week at an intensity of 75-85 % of maximum heart rate reserve). Blood samples were collected 24h before and 48h after the training. Data was analyzed by paired and independent samples t-test (P <0.05). Results: Results showed a significant decrease in serum levels of vaspin, fasting blood sugar and insulin resistance index (P value 0.001, 0.01 and 0.007 respectively) ) in experimental group and body weight, body mass index, percent body fat and waist to hip ratio significantly decreased in experimental group (P value 0.002, 0.01, 0.04 and 0.03 respectively). Conclusion: The results of this study showed that aerobic training along with decrease in body weight and percent body fat leads to significant decrease in serum levels of vaspin, fasting glucose and insulin resistance index, so can be considered as a complementary therapy method in patients with type 2 diabetes.
