This study was carried out to investigate the relationship between some body measurements and the stroke-rate (SR) and the stroke-length (SL) which are important effects on swimming performance and to investigate the effect of these body characteristics on performance. The stroke-rate and the stroke-length correlate significantly with performance in short-term tests and long-term tests. It is also a practical performance analysis component for competitions or training. 18 female (mean age 11,25 std, 0.46) and 22 male (mean age 11,42 std. 0.51) subjects were included in the study. Twenty-three different anthropometric variables were used to assess the correlation of the stroke-rate, the stroke-length and swimming speeds using statistical techniques.
The relationship between upper arm length and SR (0.022, p<0.05), time and SL (0.01, p<0.01), arm length and SL (0.049, p<0.05), forearm length and SL (0.031, p<0.05) were found for male subjects entering 100 m freestyle competition. There was no significant relationship between SL and SR with the anthropometric characteristics of female subjects entering 100 m freestyle competition.
In addition, the times of the female participants entering the 100 m freestyle competition were found to be correlated with mesomorphic (0.01, p<0.01) and ectomorphic (0.01, p<0.01) values. There was a relationship between the times of the male subjects entering the freestyle competition and the length of the sitting height (0.038, p<0.05).

Özet
Bu çalışma, bazı vücut ölçüleri ile yüzme performansına önemli etkisi olan kulaç oranı (KO) ve kulaç uzunluğu (KU) parametreleri arasındaki ilişkiyi incelemek, bu vücut özelliklerinin performansa etkisini araştırmak için yapılmıştır. Kısa ve uzun süreli testlerde kulaç oranı ve kulaç uzunluğu ile performans arasında istatistiki olarak anlamlı bir ilişki vardır. Ayrıca müsabaka veya antrenmanlar için pratik performans analizi bileşenleridir. Çalışmada 18 kız (yaş ortalaması 11,25 std. sap. 0,46) ve 22 erkek (yaş ortalaması 11,42 std. sap. 0,51) denek olarak alınmıştır. 23 farklı antropometrik değişken ile kulaç oranı, kulaç uzunluğu ve yüzme hızları korelasyon istatistik tekniği kullanılarak değerlendirilmiştir.
100 m Serbest yarışına katılan erkek deneklerin üst kol uzunluğu ve KO arasında -0,652 değerinde (p<0,05), derece ve KU arasında
-0,708 değerinde (p<0,01), kol uzunluğu ve KU arasında 0,579 değerinde (p<0,05), ön kol uzunluğu ve KU arasında 0,623 değerinde (p<0,05) ilişki bulunmuştur. 100 m Serbest yarışına giren kız deneklerin antropometrik özellikleri ile KU ve KO arasında anlamlı bir ilişki bulunamamıştır.
Ayrıca 100 m Serbest yarışına giren kız deneklerin dereceleri ile mezomorfi (0,01, p<0,01), ektomorfi (0,01, p<0,01) değerleri arasında ilişki bulunmuştur. 100 m Serbest yarışına giren erkek deneklerin dereceleri ile oturma boyu uzunluğu (0,038, p<0,05) değerleri arasında ilişki bulunmuştur.
