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.

Methods: Data were collected using a researcher-made 21-item questionnaire that 284 people were considered as a sample and answered the online questionnaire. Results: The results of this study show that the faculty members of the university do not have intense and moderate activities. But the general knowledge about the benefits of exercising during the coronavirus period has increased. Other results of this study showed that university faculty members tend to participate in sports activities in post-corona conditions. Conclusion: In a general conclusion, The Covid-19 crisis has created inactivity among human societies. Technology is expanding rapidly and people's lifestyles are changing.

Infertility is a health problem that affects about 10-15% of couples worldwide. Infertility is defined as the inability of couples to successfully conceive a child after one year of unprotected sex. The causes of infertility are often not easily identified. However, this disorder appears to be due to genetic or environmental factors, some of which may be modifiable and may be considered as a treatment option. The use of emerging infertility treatment technologies has been somewhat effective. However, these methods are very expensive and, in some cases, their success rate is relatively low. A sedentary lifestyle can lead to several disorders such as cardiovascular diseases, diabetes, cancer and conditions such as obesity. Obesity can have a negative effect on the fertility of couples. Overall, it seems that changing the sedentary lifestyle and increasing physical activity by performing regular exercise training can enhance the chances of fertility. However, it should be noted that strenuous exercise training has a negative effect on fertility.
