Critical velocity, anaerobic distance capacity, maximal instantaneous velocity and aerobic inertia in sprint and endurance young swimmers
Critical velocity (CV), anaerobic distance capacity (ADC), maximal instantaneous velocity ( V max ), and aerobic inertia ( τ ) were calculated from two (CV 2par and ADC 2par ), three (CV 3par , ADC 3par , and V max 3par ), and four-parameter model data (CV 4par , ADC 4par , V max 4par , and τ ), whi...

Summary: | Critical velocity (CV), anaerobic distance capacity (ADC), maximal instantaneous velocity (
V
max
), and aerobic inertia (
τ
) were calculated from two (CV
2par
and ADC
2par
), three (CV
3par
, ADC
3par
, and
V
max 3par
), and four-parameter model data (CV
4par
, ADC
4par
,
V
max 4par
, and
τ
), which were obtained from six different times and distances (50, 100, 200, 400, 800, and 1,500 m) swum in front crawl stroke under maximal intensity. Fourteen swimmers (14–15-year-old; sprint and endurance groups, each group
n
= 7) volunteered in this study. CV values were not influenced by the groups. The model effects showed that CV
2par
was higher than CV
3par
and CV
4par
regardless of the group used. In addition, CV
3par
and CV
4par
were similar. ADC seems to be better estimated using both three- and four-parameter models.
V
max
was higher in the sprint group regardless of the model used. The models effects showed that the
V
max 4par
was higher than the
V
max 3par
regardless of the group. Sprint and endurance groups showed similar
τ
values. The analysis of the models (
F
test, coefficient of determination
R
2
, and adjusted coefficient of determination
R
adjusted
2
) showed that the three-parameter model was more appropriate among the applied models. Although the four-parameter model showed better correlation for the endurance group, the inclusion of
τ
(fourth parameter) did not significantly improve the quality of adjustment. However, it is important to emphasize the availability of another parameter for the study of bioenergetics in swimming and other sports. |
