标题：The relationship between stroke-rate, stroke-length and some anthropometric features in 11 - 12 year old swimmers 11 – 12 yaş yüzücülerde kulaç oranı ve kulaç uzunluğunun bazı antropometrik özelliklerle ilişkisi
摘要：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).
