title: The critical velocity and 1500-m surface performances in Finswimming.
abstract: The purpose of this investigation was to determine whether the concepts of critical velocity (CV) and anaerobic swimming capacity (ASC) could be used by coaches as a reliable index in order to monitor 1500-m Surface (SF) performances in Finswimming. Thirteen Finswimmers (6 males and 7 females, 24+/-6 years), members of the Japanese national team, were instructed to swim three different swimming distances (400-, 800-, and 1500-m) at maximal effort in a 50m long course swimming pool. CV and the ASC were calculated using 400-m and 800-m swim times. Mean height and body mass were 170.2 cm and 69.7 kg in male and 160.5 and 61.0 kg in female. A highly positive correlation was found between the CV and the mean velocity of 1500-m SF (V1500) (r=0.91, P<0.01), but no correlation was found between the ASC and V1500. (r=0.46, P=0.11). However, a high correlation was found between the ASC and the residual error of V1500, calculated from the relationship between V1500 and the CV (r=0.89, P<0.01). These results suggest that the CV is a useful method for evaluating 1500-m SF performance and an aerobic performance expressed as the CV contributes to 1500-m SF performance.
