Purpose: For most trainers, the relationship between training volume and intensity as key components is a very important and effective issue. Therefore, the aim of the present study was to investigate the relationship between two key components of exhausting running at Heart Rate Deflection Point (HRDP) in girls. Methods: A number of 40 girls of physical education of Mohaghegh Ardabili University were selected as subjects with an age range of 19 to 23 years. Then, they ran individually in four separate sessions with an intensity of 70, 80, 90 and 100% of heart rate breaking point with a minimum interval of 72 hours. Using non-linear regression, the relationship between exercise volume and intensity was analyzed. Results: The findings showed that the inverse relationship between the volume (as a dependent variable) and the intensity (as an independent variable) of exhausting running at the HRDP of young girls' follows the non-linear 2nd degree function. Conclusion: According to the results of this study, it can be said that the inverse relationship between the volume and the intensity of running is non-linear. The noteworthy point is that in this estimation, the training volume was fitted based on the intensity, the relevant equation, which has a practical aspect for sports science trainers and researchers. Heart rate, as an important physiological index available to all coaches, can easily estimate the running time of young girls using the fitted equation.

By the advent of various political currents in the realm of power, the Islamic Republic of Iran has witnessed the emergence of sub-discourses that preserve the principles and propositions of the Islamic Revolution's discourse but differ in the subordinate propositions and inter-discourse developments. The latest is a "Moderationist sub-discourse" that has overcome other sub-discourses as the eleventh state started working in Iran. An important aspect of these sub-discourses is the impacts on foreign policy, especially toward the neighboring countries. In this way, Georgia gets significant importance due to its geopolitical features and the great deal of historical, cultural, and civilizational commonalities to Iran. However, due to regional and international changing conditions along with coming up various foreign policy sub-discourses, the relations between the two countries have had lots of ups and downs. On the other hand, after the Russo-Georgian 2008 war, the Russian Federation has exerted great influence on Georgian foreign policy, including relations with Iran. Therefore, this paper seeks to answer the question that, regarding the Russo-Georgian 2008 war, how has the Moderationist foreign policy discourse affected Iranian-Georgian relations? Findings of the study show that the presence of the Moderationist subdiscourse of Hassan Rouhani affected Iranian foreign policy and the pessimistic subjective impressions of the Georgian leaders toward the previous Iranian government regarding Russia's 2008 invasion of Georgia. As a result, we have witnessed a relative improvement in the relations between two countries in 2013–2017 compared to the relationships of the 2008–2013 period. This research uses the descriptive-analytical method.
