Introduction: Measurement of Maximum Aerobic Capacity (VO2-max) is important in physiologically fitting the laborers to the job. This study was conducted to estimate the Aerobic Capacity and physical work Capacity (PWC) of workers of galvanize department of Semnan rolling pipe Company and also determine the relative frequency of workers whom their jobs were proportional to their physical work Capacity.Methods: 50 male workers of Semnan rolling pipe company were selected randomly to participate in this cross-sectional study. Tuxworth & shahnavaz methods were applied to measure instances VO2-MAX. Independent-Sample t-test and correlation technique were used to analysis the data by SPSS software.Results: Average maximum Aerobic Capacity of workers was 2.88±0.033 liters per minute and the average of physical work Capacity was 4.76±0.54 kilocalories per minute. There was a significant relationship between body mass index and Aerobic Capacity. The result showed that 36 percent of subjects expend more energy than their physical work Capacity to perform their duties during the work time.Conclusion: According to the ILO classification, the average physical work Capacity of the workers fall into a category of light energy; accordingly, on average, these workers had physical ability to performe less or lighter duties. More than one-third of these workers need to undergo job modification or to change their present job to a job with less energy consumption.

2Background & Aims: One of the components of physical fitness is cardio-respiratory endurance, which is closely related to body mass profile and body fat percentage, and is necessary to maintain muscular endurance, which can be evaluated and investigated with the index of maximum oxygen consumption (1, 2). The effectiveness of sports exercises depends on their intensity, volume, time and frequency and the ability of a person to tolerate the exercises (3). In this regard, researchers have used different training methods and different results have been obtained. In this regard, therapeutic interventions with a demonstration approach are considered to be one of the few new strategies that, in addition to being relatively effective in improving anxiety symptoms in adults (11) and teenagers (12) in numerous researches, due to their inherent characteristics, have been associated with less dropout and greater adherence of people to the investigated protocols (13). Considering the mentioned cases and the importance of Aerobic Capacity in personal and social life on the one hand, the lack of general consensus on the best exercise method on the other hand, and the lack of sufficient research on physical exercise, the researchers are trying to answer the question that Does Aerobic exercise with physical performance affect the Aerobic Capacity of teenage girls or not? Methods: In order to conduct the current practical and semi-experimental research, which was conducted with a pre-test and post-test design and in a parallel random controlled method of 8 weeks. Among the teenage girls who met the criteria for entering the study, working in public and private schools of Shahinshahr city, Isfahan province, in the academic year of 1400-1401, in the elementary, first and second secondary courses, were selected using the easy sampling method (14). In order to collect data, after completing the consent form by the parents, in the pre-test stage, all the subjects performed the Queen's staircase test to measure Aerobic Capacity. Also, the Aerobic exercise program with a demonstration approach used in the Aerobic exercise-performance group included a series of moderate-intensity Aerobic exercises in the form of 30, 35, 40 and 45-minute shows derived from the movements with the 10 principles of exercise. (15) Was designed. It should be noted that during the 8-week intervention period of the present study, 30-, 35-, 40-, and 45-minute programs were used in the first 2 weeks, the second 2 weeks, the third 2 weeks, and the fourth 2 weeks of the intervention in 3 sessions per week. it placed. The training consisted of 8 weeks of Aerobic training with basic non-impact and high-impact Aerobic movements (combination of low and high contact) and Aerobic training with basic non-impact and high-impact Aerobic movements (combination of low and high contact) with a demonstration approach; The first stage: warm-up (5 minutes), the second stage: Aerobic exercises with basic Aerobic movements in order to prepare for the main exercises (10 minutes), The third stage: combined moderate Aerobic exercises, rhythmic movements, weight bearing, including movements such as leg press on the floor, simple squats (with bent knees and straight knees) and three-sided squats, dynamic and static squats, planks, lunges, hilaps, side shuffles - rolling Spinning (10 minutes for the first two weeks, 15 minutes for the second two weeks, 20 minutes for the third two weeks, and 25 minutes for the fourth two weeks) and the last step was cooling down and returning to the initial state (5 minutes). The intensity of the Aerobic exercises with a dramatic approach is balanced with the rhythm of the music and the main training program includes rhythmic and musical movement patterns that were made by several experts and taught to the subjects. And it was controlled and recorded using a polar clock (19). Finally, the data were analyzed using analysis of covariance and Bonferroni's post hoc test. Results: The results showed that eight weeks of interactive Aerobic training with physical performance has a significant effect on the Aerobic Capacity (VO2max) of adolescent girls. It was also found that there is a significant difference in VO2max changes between groups and different times. In this regard, the results of the Bonferroni test showed that there is a significant difference between the control group with the Aerobic exercise group and the Aerobic exercise group with physical performance, but there is no significant difference between the other groups. On the other hand, the results of Bonferroni's post hoc test to find the place of difference between the test times showed that there is a significant difference between the pre-test with the fourth week and the post-test on the one hand and between the fourth week and the post-test on the other hand. Conclusion: Eight weeks of interactive Aerobic training with physical performance has a significant effect on the Aerobic Capacity (VO2max) of adolescent girls. Also, there is a significant difference between the control group with the Aerobic exercise group and the Aerobic exercise group with physical performance, but there is no significant difference between the other groups. Also, between the pre-test and the fourth week and the post-test on the one hand and between the fourth week and the post-test on the other hand there is another significant difference. In line with the findings of the present study, Farahpour and Nazem showed a significant change in maximum oxygen consumption due to intermittent Aerobic exercise in adolescent girls. In the explanation of this finding, it can be said that due to Aerobic exercises, the density of the heart increases, which means that more blood and oxygen reaches the muscle tissue, on the other hand, the activity of oxidative enzymes increases, and the heart also undergoes structural changes. Found and improved (22). In general, the improvement of the maximum oxygen consumption is probably due to the increase in the oxidative Capacity of the muscles, the increase in the total amount of hemoglobin, the oxygen difference between the arteries and veins, the increase in the end-diastolic volume (cardiac output), and biochemical processes (23). It seems that since in the show group there was enough physical activity to create certain structural and physiological changes in the body, that is why in the present study the maximum oxygen consumption improved as a result of the show. On the other hand, there was a significant difference between the pre-test With the fourth week and the post-test on the one hand and between the fourth week and the post-test on the other hand, it shows that from the fourth week the exercises showed their significant effect and this effect continued until the end of the eight weeks.

Background and Objective: Accumulating evidence indicates a relation between Aerobic Capacity and glucose concentration, although the molecular mechanisms of this relationship are not fully known yet. This study was done to determine the effect of effect of 12 weeks Aerobic exercise training on Aerobic Capacity and glucose concentration in obese men.Methods: In this quasi-experimental study, thirty two adult obese males were divided into interventional and control groups. Anthropometrical indexes, fasting blood glucose and insulin, resting heart rate and Aerobic Capacity (VO2max) were measured before and after a 12 weeks Aerobic exercise in the interventional and control groups. Beta cell function was calculated by fasting glucose and insulin.Results: Long time Aerobic exercise led to significant reduction in glucose (112±10 vs. 85±11 mg/dl), anthropometrical indces, BMI (28.44±2.29 vs. 33.24±5.14), increase in VO2max (26.12±4.11 vs. 32±6.41 ml/kg/min), beta cell function (83±23 vs. 181±35) and in interventional group in comparision with controls. A significant correlation was found between the changes in VO2max with changes in beta cell function and glucose level, these correlations were independent of BMI. There was no significant change in insulin level between intervention and control groups.Conclusion: Increased Aerobic Capacity or cardiovascular fitness by exercise training improve beta cell function of glucose concentration in obese men.

Introduction: Ascorbic acid is a water-soluble vitamin solved in water that acts as a helper of some the enzymes in the reactions of energy metabolism. Thus, the study aims to investigate the use of supplemental ascorbic acid on the Aerobic and anAerobic Capacity of the children.Materials and Methods: Participants of this quasi-experimental study were 18 children in Esfahan who were randomly selected and divided into 9 groups in pair (Aerobic exercise group and the control group). For 10 days before the start of the main trial, the participants in the control group received placebo and the experimental group received ascorbic acid. The average Aerobic Capacity was measured before and after 10 days of the use of ascorbic acid. The results were analyzed by SPSS version 18.Results: Before and after 10 days of the use of ascorbic acid, the mean and standard deviation of the Aerobic Capacity of the experimental group were respectively (3.59±0.38) and (4.23±0.77) and of the control group, were (3.7±0.40) and (3.7±0.53) respectively. Therefore, there was a significant relationship between the use of ascorbic acid and placebo in terms of Aerobic Capacity (p≤0.05).Conclusion: Results of the study indicated that the use of supplemental ascorbic acid would lead to increase the children’s Aerobic Capacity. Therefore, the footballer children with no prior planning and no appropriate physical fitness who had to be involved in a heavy physical activity could use the results in order to decrease the consequences of a sudden involvement in a heavy physical activity.

The lack of Quranic approaches in the production of Quran-based humanities is still felt, despite the predominance of the philosophical approach in critical approaches to modern humanities, which has become very common in the Islamic world and in Iran for several decades. It seems that the Capacity of the method of thematic exegesis (al-Tafsīr al-mawdū'ī, Arabic: التفسیر الموضوعیّ) in this regard, can be used to bring the Holy Quran into the field of humanities. Thematic exegesis, according to whether its subject is inside or outside the Qur'an, has several functions in criticizing the structure of modern knowledge and scientific research, as well as the production of Islamic humanities. It is possible to make use of thematic exegesis of the inside of the Holy Book of Quran in order to “fundamental criticism” of the general fundamentals of humanities -the fundamentals of epistemology, axiology, ontology and anthropology- and it is also possible to use thematic exegesis for constructing and producing foundation of humanities obtained from the Holy Quran. It is used by thematic interpretation exegesis of the outside of the Holy Book of Quran -such as Shahīd (martyr) Sadr’s interrogational approach- to answer the problems of humanities and this process faces challenges such as the complexity and multiplicity of the “subject” of the humanities that exist in modern terminology of this field. It can be used in order to solve this issue in some cases to know the process of the change of the components of the modern of the conceptual history’s approach and also by analyzing the issue into several components can be shown that the components are not necessarily a product of the modern era and can be followed up in the Holy Quran and can be found up in the Holy Quran. The perspective of the Holy Quran, after that, regarding the modern subject in the desired field by the “combining” of the results obtained based on the thematic interpretation.
