摘要：As swimming performance depends on many factors, the main purpose of this study was to verify the relationship among the mean stroke cycles rate (SR), mean stroke cycle length (SL), mean swimming velocity (SV), anthropometric variables and flexibility of recreational and college swimmers. Sixteen recreational swimmers (G1) and 10 college swimmers (G2) were evaluated in three replicates maximum bouts of 25 m swimming crawl. Results showed significant correlations between SL (G1 = 1.62 ± 0.22 m; G2 = 1.55 ± 0.19 m) and (1) body mass (G2 = 65.0 ± 11.9 Kg) and (2) upper limbs span (G1 = 177.2 ± 12.3 cm; G2 = 172.6 ± 15.8 cm) and (3) height (G1 = 172.9 ± 11.3 cm; G2 = 172.0 ± 14.3 cm). Regardless levels of flexibility, significant negative correlation was found between the magnitude of ankle joint (G1 = 4.68 ± 0.70; G2 = 4.80 ± 0.91) and SV (G1 = 1.31 ± 0.21 m.s-1; G2 = 1.57 ± 0.21 m.s-1), for both groups. We conclude that SL, even among no competitive level swimmers, seems to be an important evaluation component of swimming performance.
