Introduction: Aquathlon is a sport involving swimming and running that is rising on the coast of the state of São Paulo in Brazil, both in number of events and participants in many different age
groups. Researches about the sport aiming at performance of athletes can be found on literature, however, there is scarcity on researches investigating the influence of Aquathlon on the general and
specific motor skills of children. Objective: To analyze the magnitude of the influence of an Aquathlon training program on the general and specific motor skills of children.
The study included 21 children, mean age of 11.8 years, all belonging to the public schools of the city of Santos in São Paulo. The volunteers were divided into two groups - Experimental (GE - N11),
Control (GC - N10). GE participated in an Aquathlon training program with duration of 12 weeks, frequency of 3 times per week and 90 minutes per session, 40 minutes of swimming, 10 minutes of
transition and 40 minutes of running, while the GC was not involved with the practice of formal sports. For the evaluations, it was used the individual proficiency measured by a list for the front
crawl and race; and KTK test for the general motor coordination.
Statistics: After confirming the non-normality of the data, it was decided to use the Wilcoxon test, with significance level for α≤0,05.
The data are as mean and standard deviation for both groups (EG and CG) in the pre and post, regarding the proficiency list of front crawl, the race proficiency list and general motor coordination
test in the respective order: [GE (97.2 ± 37.1 and 54.8 ± 22.2 *) p = 0.003 / GC (96.2 ± 28.7 and 87.4 ± 25.1*) p = 0.009]; [GE (58.73 ± 8.35 and 59.09 ± 6.14 p = 0.018) / (GC 60.8 ± 6.48 and 56.6 ±
6.47) p = 0.047]; [GE (320.5 ± 49.6 and 342.5 ± 36.0 p = 0.798) / (GC 320.4 ± 26.1 and 341.8 ± 38.8) p = 0.171].
-Among the evaluated variables, it is possible to observe that the Aquathlon training induced positive results regarding the qualitative improvement of coordination of swimming, being 8% for GC and
50% improvement for GE, as well as the variables involving the general coordination, where GE achieved an improvement of 6% and 5% GC, however, it was identified no difference between the groups. For
the specific coordination of the race, it did not show any significant changes within and between groups-
