23.6% (p = 0.007). Trend of a smaller decrease in swimming time in interven-
tion group is shown, and thus the impact of the intervention on swimming
skills.

Despite statistically insignificant differences, we can mention the result
improvement in intervention group (15.5%, p = 0.124) and control group (2.3%,
p = 0.949) in the breath holding under water test. A trend towards a greater im-
provement in the result in the intervention group is shown.
For other variables (swimming time 0-25 m, 25-50 m, 50-75 m, 75-100 m,
0-50 m, glide length, USD) there is no statistically significant effect of time or
time and group.
Discussion
The analysis of the results showed some changes in variables after the ten-day
intervention. Changes in maximal inspiratory strength were statistically sig-
nificant and the results increased in intervention and control group. Based on
the results, we cannot say with certainty that the increase in inspiratory mus-
cle strength is due to the intervention, although the statistical power is great-
er in the intervention group. Task learning has also an effect, which is reflected
in gradual improvement of inspiratory pressures with repeated measurements
(McConnell, 2011), but this theory can be refuted, since the subjects had the op-
portunity to try a few breaths before the first measures. In addition, we con-
sidered only the best result achieved. We assume that the intervention time
was too short to get larger differences between the group results. The results of
our research are consistent with the findings of the reviewed studies (Voliani-
tis et al., 2001, Romer et al., 2002a, Romer et al., 2002b, Griffiths and McCon-
nell, 2007, Kilding et al., 2010, Janssensl et al., 2014, Okrzymovska et al.,2019),
from which it is possible to determine the trend of greater progress in relation
of time.
