Abstract
Background: The aim of this study was to examine the association between physical activity and selected non-lipid CVD risk factors such as testosterone, free testosterone, Vitamin D, homocysteine, folic acid , and the inflammatory cytokines including hsCRP, TNF- Alpha and interleukin -6 in healthy military recruits.
Materials and Methods: A group of active personnel (n=50) engaging in a continuous and regular physical activity program, three days a week for a period of three months and a group of inactive personnel (n=50) were randomly recruited. Blood sample was collected from all participants and plasma was separated.
Results: Physically active subjects had significant lower measures of homocysteine and interleukin -6, known as CVD risk factors and tended to have nearly significant free testosterone level (p= 0.08), as a protective factor.
Conclusion: By reducing the risk factors of developing CVD events, such as homocysteine and interleukin -6 and increasing free testosterone and preventing its progression significantly, it clearly serves to underscore the beneficial properties of physical activity and to promote its effectiveness as a non- drug and non-invasive therapy in CVD events.

Abstract
Background: The aim of this study was to investigate the comparative effect of consumption of fatty acids (polyunsaturated, monounsaturated and saturated), selected nutrients (calcium, vitamin D, and boron), along regular physical activity on bone mechanical properties in rats.
Materials and Methods: Male Wistar rats weighing 140-180 g were divided into control and six treatment groups (n=8/ each group) and treated for eight weeks as following: Group 1 (control): regular food and drinking water Group 2 (Sport Sp): same as Gr.1 + physical activity (Whole body vibration WBV) Group 3 (SPM): same as Gr.2 + Calcium, Vit. D, Boron Group 4 (Co): same as Gr.3 + canola oil Group 5 (AF): same as Gr.3 + sunflower oil Group 6 (AC): same as Gr.3 + sunflower and canola oils and Group 7 (N): same as Gr.3 + coconut oil. After interventions, frozen plasmas were analyzed and mechanical properties of femurs, tibias, and lumbar bones were determined. One way analysis of variance (ANOVA) was used to evaluate the effects of different treatments.
Results: Analysis of data between the groups revealed significant increase in serum levels of estradiol (E2) in group 7 (N), (p<0.05). In addition, serum levels of testosterone (T) in groups 4 (Co) and 7 (N), and free testosterone (FT) in the group 7 (N) had a remarkable, but non-significant increase. As a result of vibration training, similar trend was observed for serum levels of vitamin D in the group 4 (Co) and 5 (AF). The stiffness and the breaking strength (Fmax) of the femur bone in the group 7, and the breaking strength of the lumbar bone in the group 7 compared to the control and the groups 4 and 5 was significantly higher and tended to increase compared to the group 6.
Conclusion: Better and stronger measurements observed for coconut oil is warranted to further study its effect on biomechanical properties of bones.
