Regular training programs are applied to train ballet dancers, as in sports. Each exercise performed during training, including ballet training, prepares the body for the next exercise.

The research aims to investigate the effects of anthropometric characteristics of students receiving ballet education at the conservatory on battement développé, grand battement and sauté movements. The aim was to determine the effect of the four month training period on the performance of the students via the pulse variable.

The findings obtained in the research may contribute to the development of the educational processes of ballet students. Our study is one of the few studies in Türkiye that measures the physical characteristics and basic technical performance of ballet students.

The research was implemented as an experimental study. Our research was conducted with the voluntary participa tion of secondary school (6th, 7th and 8th grades) and high school (9th, 10th, 11th and 12th grades) students studying in the Ballet Department of the Performing Arts Department of Hacettepe University Ankara State Conservatory. Male and female conservatory students who were receiving ballet training and were born between 2012 and 2006 participated. The research was completed with a total of 46 students, 13 girls and 3 boys from middle school and 24 girls and 6 boys from high school. Participating students practiced ballet 2 hours a day, 5 days a week for a total of 4 months during one semester.

Anthropometer was used to measure the height of the ballet students, digital scales were used to measure their weight, Polar was used to measure their pulse at rest and during ballet performance, and goniometer was used to measure the hip joint range of motion. In ballet performance measurements, battement déveleoppé, grand battement and sauté were selected from the basic movements to monitor the development of students' technical levels. Battement déveleoppé and grand battement movements were examined both in the barre and in the middle, and the sauté movement was examined only in the middle as it is a jumpingtype movement. Instantaneous pulse measurements were made during these movements performed by the students. Beginning and endof term analyses of selected movements comprising ballet performances were carried out by video recording. The measurement data of the students were analyzed statistically for middle school female students, high school female students and all male students. Since the measurement data did not show a normal distribution, the Wilcoxon Signed Rank Test was used in statistical analyses.

It was determined that four months of ballet training did not produce a statistically significant result in the range of motion values in the hip region flexion and hyperextension movements of the groups covering middle school girls and all boys (p>0.05). It was determined that four months of ballet training produced statistically significant results in the range of motion values of the hip region flexion movement of high school female students (p<0.05). It was found that there was a statistically significant result in the left leg values of high school female students' hip hyperextension values.

It was understood that there was no statistically significant change in the pulse values of the 6th, 7th and 8th grade secondary school female students after four months of ballet training (p>0.05). The significance value of the development level of the students in the sauté movement performance was determined as 0.08. After four months of ballet training in groups of high school female students, a statistically significant improvement was found in the performance of battement déveleoppé, grand battement and sauté movements (p<0.05). Training studies on battement déveleoppé and grand battement performances in male students did not create a statistically significant development effect (p>0.05).

Before ballet training, the hip flexion joint movement angle data of all students showed similarity between the two legs (p>0.05). At the end of the training period, it was determined that the asymmetry difference of female secondary school students increased statistically (p<0.05). Ballet training reduced the asymmetry difference in hip flexion values of all male and female high school students. An increase in hip hyperextension asymmetry difference level was detected after the ballet training period of all students (p<0.05).

Especially since the battement déveleoppé movement was performed at a slower tempo, the difference in movement asymmetry between the legs became more clearly evident. The students' sauté movement performance was consis tent with technical improvement as determined by the improvement in their pulse values.

To ensure successful technical development of students, it may be appropriate to perform exercises aimed at reducing asymmetry differences during training.
