Interventions
Group 1: Competitive athletes receive a one-time gait analysis on the treadmill using videorasterstereography.

Inclusion criteria
Inclusion criteria: 1. subjects of both biological sexes between 18 and 30 years. 2. test persons who have been practicing competitive sports for a total of at least 12 months with a training frequency of 5 units per week for at least 1 hour each. Training breaks, such as vacation days or injury breaks, do not count. 3. 50 % of the test persons should only participate in sports that include running as an important component, such as long-distance runners, sprinters, or soccer players. 4. 50 % of the test persons can participate in different sports in which running is required for the exercise of the discipline.
Exclusion criteria
Exclusion criteria: 1. subjects who have received surgical treatment to the musculoskeletal system in the last 6 months or have had an injury that resulted in a training break of > 3 weeks. 2. subjects who have suffered from musculoskeletal complaints (including back pain) requiring treatment in the last 6 weeks, resulting in consultation with a physician and who have been treated with prescription drugs, physiotherapy, osteopathy, or other remedies. 3. subjects who report pain while walking on the agreed examination date, which is of intensity > 0 on the Numerical Rating Scale (NRS). 4. subjects who have had spinal surgery (nucleotomy, spondylodesis, etc.) and/or pelvic surgery in their past life, or have had severe pelvic and/or back disease/injury (discectomy, vertebral fracture, pelvic fracture, etc.). 5. subjects who participate in disability sports. 6. subjects whose walking speed and resulting walking distance are limited. Verification will be done in the context of a 2-minute walking test. There will be a. female subjects excluded from study participation if the achieved walking distance after 2 minutes is 12 seconds to complete the timed-up-and-go test (TUG) on the agreed examination date. 10. subjects who achieve a test score of = 2 points on the Back Performance Scale (BPS) test administration. 11. subjects who have back contour changes due to large scars, tumors, or due to tattoos in the measurement area. 12. subjects who have a BMI > 30 kg/m² on the agreed examination date. 13. subjects who have taken painkillers on the agreed examination date. 14. subjects suffering from cold symptoms (cough, fever, etc.) on the agreed examination date, have a confirmed COVID-19 disease. 15. subjects who have had a deliberate contact with a positively tested COVID-19 patient or have been in a risk area declared by the Robert Koch Institute in the two weeks prior on the agreed examination date. 16. subjects suffering from an acute medical condition, such as dizziness, nausea, balance disorders, or injury, on the day of the agreed examination date. 17. subjects who are not fully capable of consent or understanding on the agreed examination date. 18. subjects who are pregnant on the agreed examination date. 19. subjects who suffer from fluctuating disease processes (e.g. multiple sclerosis).
