Resumo(s)
The aim of this study was to compare the swimming velocity in frontcrawl
between age-group swimmers using discrete variables against
Statistical Parametric Mapping (SPM). The sample consisted of 30
young male swimmers divided into three groups (each with 10
swimmers) based on their age (group #1: 13.60 ± 0.84 years; group
#2: 15.40 ± 0.32 years; group 3: 16.39 ± 0.69 years). Swimmers performed
three maximal trials in front-crawl. The best performance
was used for analysis. Comparison of swimming velocity between
groups was analysed using discrete variables and as a continuous
variable (SPM). As a discrete variable, the mean swimming velocity
showed a significant difference between groups (p < 0.05). Moreover,
when analysed by SPM, swimming velocity showed a significant
difference (p = 0.021) between the ~ 44% and ~ 51% of the stroke
cycle (transition of the propulsion phases between sides). Post-hoc
comparison revealed a significant difference between group #1 and
group #3 only in SPM analysis. Researchers, coaches, and practitioners
should know that both measurement approaches can be
used simultaneously. However, SPM offers more sensitive and accurate
results about the swimmers’ stroke cycle.
