The goal of this clinical trial study is to evaluate the effect of subdermic etonogestrel implant on body composition, sport performance parameters, quantify bleeding patters and quality of life parameters among young female soccer players.
Studies indicate a worsening of performance in young people with excessive menstrual bleeding and menstrual cramps. Hormonal contraception has been used to "manipulate" menstrual symptoms among physically active women, amateur and elite athletes. The use of the etonogestrel subdermal implant (Implanon NXT) would be a good option for young female soccer players. The goal of this study is to evaluate some parameters among young female soccer players under 17 years old during one year, in use of subdermic etonogestrel implant comparing with a non-users subdermic etonogestrel implant

Each implant contains 68 mg of etonogestrel. The release rate is approximately 60-70 mcg/day in the 5th-6th week and reduces to approximately 35-45 mcg/day at the end of the first year; 30-40 mcg/day at the end of the second year and 25-30 mcg/day at the end of the third year. It will be evaluation before, 3, 6, 9 and 12 months after implant insertion.Participants' use of the device will be evaluated for one year

Anthropometric Measurements
Weight in kilograms
Time frame: Clinical, body composition and sport parameters will be evaluation before, 3, 6, 9 and 12 months after implant insertion.
anthropometric measurements
skinfolds in millimeters
Time frame: Will be evaluation before, 3, 6, 9 and 12 months after implant insertion.
anthropometric measurements
Height in meters
Time frame: Will be evaluation before, 3, 6, 9 and 12 months after implant insertion.
Body Composition
Weight in kilograms and skinfolds in millimeters will be used to measure the athletes' body composition (body composition is used to assess an individual's percentage of body fat and percentage of fat-free mass)
Time frame: Will be evaluation before, 3, 6, 9 and 12 months after implant insertion.
anthropometric measurements
Weight (in kilograms) and height (in meters) will be used to obtain the BMI (body mass index) (kg/m²)
Time frame: will be evaluated before, 3, 6, 9 and 12 months after implant insertion.
Sports Performance Parameters
* Kicking Tests : It consists of targets set on a goalkeeper divided into sectors with specific scores, and the numerical values reflect the accuracy of the shot.The goalkeeper is divided into 6 horizontal sectors, with scores assigned to each sector. For example: * Lower and central sectors: 2 points. * Upper and lateral sectors: 4 points. * Shots off goal: 0 points. The player takes 10 shots from within a delimited area (usually the penalty spot).The total points obtained in the 10 kicks are added together.

Time frame: sport parameters will be evaluation before, 3, 6, 9 and 12 months after implant insertion.
Sports performance parameters
Dribbling test: evaluates ball control and agility, challenging the player to maneuver the ball through obstacle courses in a limited time without losing control.The course is set up with cones spaced alternately in a straight line: * Cones positioned every 2 meters, totaling 5 cones on a 10 meter path. * The start and finish line is marked. Test Execution 1. The athlete starts behind the starting line with the ball positioned on the ground. 2. On command, the athlete dribbles the ball around the cones to the end line, returning to the starting point (round trip). 3. The test is timed from start to finish. Scoring and Numerical Values * Total Time: Performance is recorded in seconds * Penalties: * Each cone dropped or incorrectly deflected adds 2 seconds to the final time. * Losing control of the ball outside the path adds 1 second per occurrence. * Evaluation Criteria: Excellent: ≤ 10 sec; Good:10.1 to 12 sec , Regular: 12.1 to 14 sec and Weak \> 14
Time frame: Will be evaluated before, 3, 6, 9 and 12 months after implant insertion.
