Investigation of changes in flexibility and lung capacity among girls beginner synchronized swimming and free style swimming between ages of 6-9

The aim of the study was to investigate the effect of swimming on lung capacity and assess the effect of different dry land training in synchronized swimmers on flexibility in girls. The participants were either Synchronized swimmers (SG) (n=12) or Freestyle swimmers (FG) (n=12). The groups were separated according to their swimming style.The study included 24 beginner swimmers (24F;6-9ages)who continue to different swimming clubs in Istanbul, Turkey between January 2019 and April 2019 for three months from beginning evaluation. Pulmonary functions of all the swimmers were evaluated by spirometry, Forced Vital Capacity (FVC) and Forced Expiratuar Volume (FEV1). Flexibility were assessed by Sit and Reach test. In this study, IBM SPSS Statistics 22 for statistical analysis (SPSS IBM, Turkey) programs were used. There was no statistically significant difference between the values FVC and FEV1 of synchronized and freestyle swimmers before and after (p> 0.05). And also that showed no statistically significant changes between the groups in terms of the amount of increase seen in the last flexibility levels compared to the first flexibility levels (p> 0.05). But in both groups there was a significiant difference between the previous and the last evaluation. . As a result of this study if there will be a longer-term study with more participants, more meaningful results can be achieved. Key Words: Synchronized swimming, freestyle swimming, pulmonary function, FVC, FEV1, flexibility, sit and reach test, dry-land exercises.
