Table
1.
Anthropometrical,
physiological and biomechanical parameters and their correlate with
100-m front crawl swimming performance in adolescent swimmers (n = 25).
Data are means (± standard deviations, SD), minimal and maximal values,
and partial correlation coefficients (rp)
with age as control variable.
