Abstract
Introduction: The definition of body posture involves a relative arrangement of body parts. Football is the most popular sport in the world with an injury rate of 4.47 injuries per 1000 hours of play/training per athlete. Photogrammetry is a valid and reproductive method for evaluating postural differences with quantitative and accurate results. The aim of this study is to present a postural analysis of children and young football players, using photogrammetry.
 Method: The sample consisted of 263 athletes (ages between 4 and 18 years) where, through the photographic register and use of SAPO® software the main postural deviations of the children were calculated and subsequently analyzed descriptively in the IBM SPSS software.
 Results: The results obtained show deviations in point A1 - alignment of the acromion (21.4% to 50% of athletes on the right (R) and 16.7% to 40.5% of athletes on the left (L); A2 - alignment of the anterosuperior iliac spine (42.9% of athletes to (R) and 14.3% to 64.9% to the left (L); A3 alignment of tibia tuberosities (27.9% to 55% of athletes (R), 27% to 48.5% of athletes (L); A4 and A5 – angle Q (R and L) (50% to 91% of athletes with tendency to knee varus); A6 – horizontal alignment of the pelvis (tendency to hyperlordosis of 28% for juveniles with an average deviation of -15.4° ± 7.7).
 Conclusion: The postural analysis of the athletes allows a better knowledge about the most frequent deviations that, over time, can become painful, being important an intervention and specific planning at this level, trying to prevent future injuries.

Body posture is defined as the relative arrangement of body parts [1], [2], and so, bad posture is a defective relationship between the various parts of the body that produces greater tension in the support structures, and where less efficient body balance occurs in the support base [3], the deviations being acquired by the adoption of bad postural habits, muscle shortening, muscle hypertrophy, antalgic positions, causing pain due to the overload of some muscles [4]
Summary
The definition of body posture involves a relative arrangement of body parts. Football is the most popular sport in the world with an injury rate of 4.47 injuries per 1000 hours of play/training per athlete. Injuries to the knee joint present around 50% of musculoskeletal injuries, within them, the most common is patellofemoral dysfunction [8] as well as low back pain, being considered the most common injury in elite football players [9]. Factors such as the age of the player and underlying structural damage, cause a greater risk of contracting this injury for a long time [10] and so an influence on the performance [11]
