The aim of this study is to determine the quadriceps femoris muscle angle (Q-angle) of elite and sub-elite female weightlifters, and also to examine the relationship of Q-angle with some physical parameters, training experience and weightlifting performances. Elite weightlifters (EWL) participating in international Olympic style weightlifting championships (n=18) and sub-elite healthy female weightlifters participating in weightlifting championships in National-International Weightlifting Tournaments participated in the research (n=18). The Q-angles were determined with a goniometer in the supine position at rest. Also, thigh length (TL), thigh girth (TG), pelvic width (PW) and knee extension-flexion muscle strength were measured. Statistical analysis was conducted with SPSS program. p< .05 was accepted significantly. No difference was observed between the demographic and anthropometric values of the EWLs and sub-EWLs (except for age; p>.05). It was determined that the right-left Q-angle values of the sub-EWLs (16.67±2.43o and 18.28±2.70o, respectively) were greater than the EWLs (14.56±2.68o± and 14.94±2.21o, respectively, p<.05, p<.001, respectively). Differences were detected between the right-left Q-angles of sub-EWLs (p<.05). In sub-EWLs, it was observed that the right Q-angle was positively correlated with weightlifting performances and training experience (p<.05). In this study, it was observed that while weightlifting performance increased depending on the elite weightlifting level, the Q-angle decreased.

Olimpik Stil Halterde Elit ve Sub-Elit Kadın Haltercilerin Q-Açıları

Öz

Bu araştırmanın amacı, elit ve sub-elit kadın halter sporcularının quadriseps femoris kas açısını (Q açısı) belirlemek ve ayrıca, Q açısının bazı fiziksel parametreler, spor seviyeleri ve halter performansları ile ilişkisini incelemektir. Araştırmaya uluslararası Olimpik halter şampiyonalarına katılan elit halterciler (EH), (n=18) ve ulusal-uluslararası halter turnuvalarında halter şampiyonalarına katılan sub-elit sağlıklı kadın halterciler (n=18) katılmıştır. Q açıları, sporcular sırtüstü yatar pozisyonunda hareketsizken bir gonyometre ile ölçüldü. Ayrıca, uyluk uzunluğu (UU), uyluk çevresi (UÇ), pelvik genişlik (PG) ve diz ekstansiyon-fleksiyon kas kuvvetleri ölçüldü. İstatistiksel analiz; t-Test, eşleştirilmiş örneklem t-Testi ve Pearson korelasyon analizleri ile SPSS programıyla yapıldı. p< .05 anlamlı olarak kabul edildi. EH ve sub-EH’lerin demografik ve antropometrik değerleri arasında yaş haricinde fark gözlenmedi (p>.05). Sub-EH'lerin sağ-sol Q açısı değerlerinin (sırasıyla 16,67±2,43o ve 18,28±2,70o) EH'lerden (sırasıyla 14,56±2,68o± ve 14,94±2,21o), p<.05, p<.001, sırasıyla) daha büyük olduğu belirlendi. Sub-EH'lerin sağ-sol Q açıları arasında da farklılıklar tespit edildi (p<.05). Sub-EH'lerde sağ Q açısının vücut kitle indeksi, sağ UU, sol UÇ, PG, halter performansları ve spor geçmişi ile pozitif ve anlamlı olarak ilişkili olduğu görüldü (p<.05). Bu araştırmada, elit halter seviyesine bağlı olarak halter performansı artarken, Q açısının azaldığı gözlendi.
