Background & 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.
