Soil's reaction Compared to the imported forces to it, is under the influence of soil's resistance to pressure, shear and attracting force between soil and other materials and friction. All of these mentioned facts are dynamic properties of the soil and the reason to their apearence is displacement. Most imported forces to machines and soil are through wheels. The force that wheel will spend to overcome friction is Rotational resistance (R). Determination of Rotaional resistance requires soil's stifness coefficients. In this research to determine the relation between soil stiffness coefficeints ((K_c ), (K_∅ ), n) between moisture and loading speed and soil pattern, two soil patterns which they were Loam and Clay-Loam were tested in 4 moisture levels (10%, 20%, 30%, 40%) and five loading speeds of 1mm/s to 5 mm/s. 160 tests took place.

One of the physiological changes responsible for health and cardio metabolic benefit of exercise could be mediated by changing the secretion of adipokines which is suggested to involve in inflammation. Adiponectin and retinol binding protein-4 (RBP4), adipose tissue derived-adipokines, are related to inflammation and cardio metabolic risk factors. Adiponectin exerts cardio protective effect [4] and inhibits signal triggering inflammation [5]. Low plasma adiponectin level appeared to have correlation with higher level of cardio metabolic risk factors [6]. In contrast, some evidence

The subjects were randomly divided into experimental and control groups. Subjects of experimental groups were forced to perform a heavy resistance exercise with the intensity of 70-80% of 1RM in selected movements. The blood samples were taken from all subjects four times; before (T1), immediately after (T2), 5 (T3), and 8 (T4) hours after exercise. Analysis of data showed that a session of heavy resistance exercise induced significant increase in GH at T2 (P \ 0.05) and a significant decrease in insulin at T4 (P \ 0.05) and a significant decrease in IGFBP3 at T4 (P \ 0.05) in trained group. In untrained group, no significant change in any of the variables was observed. However, the procedure of response in variables was almost similar in two experimental groups. Although, the exercise did not appreciably affect IGF-1 levels, it decreased in all groups at length of time after exercise. In addition, the exercise did not have any notable effect on IGFBP1 levels over time. In conclusion, the findings of this study indicate that the intense resistance exercise can lead to changes in blood concentrations of IGF-1 system components which are observable in blood circulation over time and the amounts of changes depend on subjects' fitness levels and exercise variables.

Methods: Nineteen healthy men among physical education students as trained group and 15 healthy men among non-physical education students as untrained group voluntarily participated in this study. The subjects randomly were divided into experimental (trained and untrained) and control (trained and untrained) groups. Blood samples were obtained just before; and at immediately, four and seven hours after the end of exercise. Serum concentrations of GH, Insulin, total IGF-1, IGFBP1 and IGFBP3 were determined. Results: No significant difference was observed in the pre-exercise concentrations of variables between the trained and untrained individuals. However, a strong and positive correlation between areas under curves of variations in IGF-1 and IGFBP3 was identified in the experimental trained group (r=0.872 and p=0.001); and also, there was correlation between areas under curves of variations in Insulin with IGF-1 (r=0.752 and p=0.05) and in IGF-1 with IGFBP3 (r=0.922 and p=0.003) in the control untrained group, but no statistically significant relationship was observed in the control trained and experimental untrained groups. Conclusion: Overall, there was no relationship between acute changes in levels of IGF-1 components with GH and insulin after resistance exercise and the role of each component of the system in mutual regulation of the other components may be more important than nonmember factors of the system during exercise and the following recovery period.
