Artistic swimming a complex and physically demanding sports, in which the strength and the velocity of movements are combined with high flexibility requirements. Flexibility is one of the main physical abilities required in Artistic swimming. This sport requires athletes to have a high level of physical training, mastery of complex technical skills, and artistry. The level of athlete's flexibility is an important prognostic indicator of performance. The aim of study: to determine the effect of static and dynamic stretching on improving the flexibility in artistic swimming. Methodology: 7 female subject's aged 11 years, height 135.00 cm, Weight 33.00 Kg were selected to participate in this study were assigned to one experimental group, participated in 6 weeks as static and dynamic stretching exercises. The program targeting on specific muscle groups around the hip joint to increase flexibility and contributing better performance in the water including Hip Flexors, Hamstrings, Gluteus, Inner Thighs and Hip Rotators. Results: The results of this study indicate significant improvements in flexibility across various measures following a targeted program. The findings align with existing researches on flexibility training, which suggests that structured stretching routines can enhance joint range of motion and overall flexibility.
