The Relationship Between Football Participation Level and Lower Leg Alignment in Youth Males: Genu Varum

Abstract

The aim of this study was to determine the effects of football participation levels on genu varum ratings by using Q angle and intercondylar distance. Twenty male football players for each elite and amateur football teams and 20 sedentary young male volunteers participated in this study. The anthropometric variables (body height, body weight, body fat percentage, body mass index) and genu varum levels by evaluating the lower extremity alignment using intercondylar distance, and Q angles for both legs were measured. The intercondylar distance measurements were done by using caliper with the sensitivity of 0.01 mm and Q angle measurements were carried out by the examination of the photographs of participants. One Way ANOVA and post-hoc Tukey test were used to assess statistically intra-group differences. Cohen's Kappa coefficient were used to determine agreement among observers. SPSS v.25 program was used to analyse the data. Intercondylar distance values were found significantly higher in elite group than in amateur and sedentary groups (45.65 ± 13.54; 28.84 ± 14.61; 3.70 ± 5.19 mm, respectively, p<0.001). As a result of this study, it was determined that the participation level of football trainings lead an increase in intercondylar distance significantly. The highest Q-angle values were observed in amateur football players.

Deformiteti Kolena Kod Fudbalera - Meta Analiza

“…Zaklјučili su da odstupanje u osi kolena varusa bilo je češće kod fudbalera nego kod tenisera. Rezultati istraživanje koje su sproveli Melekoğlu & Işın, (2019), gde su kao parametre genu varuma koristili interkondilarni ugao i ugao kvadricepsa, pokazuju da su vrednosti interkondilarne udalјenosti bile značajno veće kod fudbalera profesionalaca nego kod amatera i nesportista (p <0,001). Utvrđeno je da nivo učešća na fudbalskim treninzima značajno povećava interkondilarnu udalјenost.…”

Evaluation of Q Angle, Lower Extremity Flexibility and Muscle Shortness in Wrestlers

“…When the literature was examined, it was seen that there were studies determining the Q angle, examining it in terms of some variables, and investigating its relationship with some parameters in athletes. Melekoğlu and Işın found out that the Q angle was higher in amateur football players when compared to elite football players and non-athletes (16). Mohanty and Koley found in their study that there was a significant positive correlation between right femoral anteversion, right tibial torsion, and right navicular drop with right Q angle (17).…”

Comparison of Lower Extremity Alignment among Taekwondo Athletes of Various Subdisciplines

“…Increased tension in soft tissues can lead to musculoskeletal stress, damage to surrounding soft tissues, and misalignment. In particular, misalignment is a risk factor for noncontact injuries in taekwondo athletes because it causes the structural deformation of bones, abnormal arthrokinematics (the excessive motions between articulating joint surfaces in all three planes of motion), and improper force distribution in the lower extremity joints [ 10 , 11 , 12 , 13 ].…”
