a 30-min test by the CSS 10 in adult male swimmers (18.6 ± 1.9 years).
Studies also found that the speed of a 20-min test in adolescents or
a 2000-m test in adults was similar to the speed at Lactate threshold
(Greco et al., 2003; Matsunami et al., 1999). However, further studies
are needed to check whether or not it would be erroneous to use a
single correction factor to predict the velocity over a 30-min test or V 1500
through CSS 10 both in adolescence and adulthood, as these differences
seem to vary during the development of swimmers (Dipla et al., 2009).
conclusIon
Css 1 (50-100m) was the model that most overestimated css 10 (200-
400m). The lowest error in the estimation of css 10 was observed with
css 3 (-0.5%) and css 7 (0.8%). Css 10 overestimated v 1500 by +3.5%. Css 10
(200-400 m) was higher than v 1500 (+3.5%) with performances over
this distance ranging from 19.5 to 22-min (1231 ± 88 s) in young male
swimmers. Having access to information of possible differences between
css 10 and other combinations for predicting css seems important when
for some reason the coach needs to calculate css with other distances. It
might suggest studies to measure the level of agreement between css 10 vs
the other combinations and between css 10 vs v 1500 to check whether this
level of agreement will be maintained until adulthood.
