The objective of the present study was to investigate the effect of lying on the stomach on the spine angles of 13-18 year old students in Karaj. For this purpose, 105 13-18 year old students of girls' schools in District 3 of Karaj, who were accustomed to lying on the stomachs, randomly participated in the study by convenience sampling method and based on the number of study hours per day, less than 1 hour, between 1 and 2 hours and more than 2 hours placed in three groups. angles of forward head, unequal shoulder, lumbar lordosis, dorsal kyphosis and scoliosis were assessed using standard tests with high validity and reliability. The data were analyzed using one-way analysis of variance and Bonferroni test at the significance level of 0.05. A significant difference was between lumbar lordosis and forward head angle among students who were less than 1 hour and more than 2 hours accustomed to lying on their stomachs(P<0.05). But this difference was not significant for variables of uneven (dropped) shoulder, dorsal kyphosis and scoliosis(P<0.05). The students who studied for more than 2 hours a day while lying on their stomachs had abnormalities of lumbar lordosis and forward head angle. .

Purpose: The objective of this study is to analyse various articles on the effect of various types of exercise on the angiopoietins family and angiopoietin-like proteins (ANGPTLs). Methods: PubMed, Science Direct, Scopus and Google Scholar databases were searched from 2000 to September 2020. After screening the articles, 19 articles that met the inclusion criteria were studied and analysed. Results: In our body, four types of angiopoietin and eight types of angiopoietin-like proteins have been identified, the functional method of some of them which are still not entirely understood. Angiopoietin-1 and angiopoietin-2 are essential regulators of vascular formation and maintenance. Angiopoietin-1 is found in perivascular and vascular cells within and around smooth muscle cells and plays an important role in growth, vascular stability, and pathological angiogenesis. On the other hand, angiopoietin-2 and angiopoietin-3 are mainly involved in inducing vascular regression, cell death, and inflammation. Angiopoietin-4, like angiopoietin-1, is responsible for the maturation, stabilization, and stasis of blood vessels. Conclusion: Studies show that exercise has a significant effect on increasing capillary density in the human body by increasing angiopoietin as one of the angiogenesis factors. In addition, there are many other benefits such as contribution to fat burning and treatment of coronary artery disease, cancer, asthma, and ischemia. More research is needed on the effects of different types of exercise training on angiopoietins.
