Q-Angle, Segment Length, Quadriceps, and Knee Alignment in Soccer Players
Sponsor: Suleyman Demirel University
Summary
The aim of this study is to investigate the relationship of Q-angle, lower extremity segment lengths, and quadriceps muscle activation with dynamic knee alignment during a single-leg squat in active soccer players. Study hypotheses: H1: There is a significant relationship between Q-angle and dynamic knee alignment during a single-leg squat in active soccer players. H2: There is a significant relationship between femur length and dynamic knee alignment during a single-leg squat in active soccer players. H3: There is a significant relationship between tibia length and dynamic knee alignment during a single-leg squat in active soccer players. H4: There is a significant relationship between the ratio of lower extremity segment lengths and dynamic knee alignment during a single-leg squat in active soccer players. H5: There is a significant relationship between the level of quadriceps muscle activation and dynamic knee alignment during a single-leg squat in active soccer players. H6: When Q-angle, lower extremity segment lengths, and quadriceps muscle activation are evaluated together, they are significantly associated with dynamic knee alignment during a single-leg squat in active soccer players.

Interventions
Group 1
The study was designed to include individuals aged 18-35 who actively play football, voluntarily agreed to participate, had engaged in regular football training over the past six months, were able to perform a single-leg squat independently during the assessment, and had no acute musculoskeletal issues that could affect the measurements. All assessments for this group will be conducted by a doctor of physiotherapy. Plans were made to regularly record participation rates and measurements. For each player, measurements of the Q-angle, lower extremity segment lengths, surface electromyography, and dynamic knee alignment during a single-leg squat were planned for the dominant lower extremity.
