ELİT GENÇ ERKEK BASKETBOLCULARDA SİRKADİYEN RİTMİN MAÇ PERFORMANSINA ETKİSİ

Bir basketbol maçını kazanabilmek için fiziksel, fizyolojik, psikolojik, biyomotor, bilişsel, teknik ve taktik özelliklerin gelişmiş olması gerekmektedir. Bu özelliklerin sirkadiyen ritimden etkilendiği, bu nedenle günün farklı saatlerinde söz konusu performansların değişebildiği bilinmektedir. Bu araştırmada, sirkadiyen ritmin 18 Yaş Altı Erkekler Basketbol Türkiye Şampiyonasına katılan takımların performanslarına olan etkisi incelenmiştir. Türkiye Basketbol Federasyonu resmi sitesinde açık erişimli olarak paylaşılan beş turnuvadaki 208 maçın istatistik verisi toplanmıştır. Araştırmaya sadece uzatmaya giden ya da 10 sayıdan az farkla biten 97 maç dahil edilmiştir. Bu maçlarda takımların istatistik verileri toplanmış ve her maç için takım başı birer veri seti olmak üzere toplamda 194 farklı takım istatistik verisi incelenmiştir. Sirkadiyen ritmin performansa etkisini incelemek için maç istatistikleri ile maç başlama saati arasındaki ilişki test edilmiştir. Ayrıca sabah ve akşam saatlerindeki maçların istatistikleri de birbirileriyle karşılaştırılmıştır. Korelasyon analizi sonucu iki sayılık deneme ve asist istatistiklerinin maç saati ile negatif; üç sayılık deneme, serbest atış deneme, başarılı serbest atış ve faul istatistiklerinin ise maç saatiyle pozitif korelasyon gösterdiği belirlenmiştir (p<0.05). Sabah ve akşam maçlarının karşılaştırılması sonucu ise saha içi deneme, iki sayılık deneme ve asist istatistiklerinin sabah maçlarında; serbest atış yüzdesi, serbest atış deneme, başarılı serbest atış ve faul istatistiklerinin ise akşam maçlarında daha fazla olduğu tespit edilmiştir (p<0.05). Ulaşılan bulgular ışığında akşam maçlarında şutör oyunculara verilen sürenin artırılması ve takımın önemli uzun oyuncularının faul problemine girme ihtimali göz önünde tutularak stratejik planlanmaların yapılması önerilmektedir. Sabah maçlarında ise kolay penetre yememek ve yenilen penetreleri daha etkili savunabilmek için taktik hazırlıkların planlanmış ve çalışılmış olması oldukça önemlidir.

THE EFFECT OF CIRCADIAN RHYTHM ON GAME PERFORMANCE IN ELITE YOUTH MALE BASKETBALL PLAYERS

Winning a basketball game requires advanced physical, physiological, psychological, biomotor, cognitive, technical, and tactical attributes. These attributes are affected by circadian rhythm. Hence mentioned performances might be altered during different times of the day. In this study, the effect of circadian rhythm on the team performances in the Under-18 Men’s Turkish Basketball Championship was investigated. Statistical data from 208 games, available open-access on the official website of the Turkish Basketball Federation, were collected. 97 games, which ended with an overtime period or a final difference lower than 10 points, were included. The statistical data of the teams were collected and a total of 194 different statistical team data (two per game) were examined. To investigate the effect of circadian rhythm on performance, the relations between the game statistics and the game starting time were analyzed. Also, statistics of the morning and evening games were compared with each other. The correlation analysis revealed that the game starting time was negatively correlated with two-point attempt and assist statistics; but positively correlated with three-point attempt, free throw attempt, free throw made, and foul statistics (p<0.05). The comparison of the morning and evening games showed that field goal attempt, two-point attempt, and assist statistics were higher in the morning games; but free throw percentage, free throw attempt, free throw made, and foul statistics were higher in the evening games (p<0.05). For the evening games, increasing the playing time of the successful shooters and planning strategies to protect important centers from foul trouble are recommended. For the morning games, tactical preparations for stopping and defending more effectively the penetrations of the opponent, are important.
