Summary: Introduction: Cardiorespiratory fitness is one of the most important variables in the
evaluation of physical fitness. Although there are studies addressing
cardiorespiratory fitness among adolescents, few evaluated these submaximal
responses (LAV and RCP) among 14- and 15-year-olds using direct measures.
Objective: To test the hypothesis that students who participate in EF classes together
with a systematic training in their counter-school shift will have better conditioning
at submaximal levels of the exercise when compared to those who only do EF
classes. Methods: 45 students with mean age of 14.6 ± 0.5 years, 25 boys, 16 athletes
(GA) and 9 non-athletes (GNA) and 20 girls (GA = 8, GNA = 12) were submitted to
CPTE. The variables evaluated were VO2máx, %VO2LAVmáx, HRmáx, % HRmáx,
RTR in both submaximal thresholds. To test the normality of the data the Shapiro
Wilk test and the non-parametric Mann-Whitney test were used. To compare the
means of CPET between the groups, the Univariate Variance Analysis - general
linear model (ANCOVA) was used to determine the differences between groups
controlling for standard demographic variables such as maturation and percentage of
body fat (%GC). Results: the results obtained in the comparison between the male
groups revealed that there were differences in the submaximal variables (VO2LAVmáx,
%VO2LAVmáx and velocityLAV, VO2RCPmáx, and velocityRCP). The data obtained in the
comparison between the female groups revealed that GNA presents values of
metabolic and cardiac variables very close to the GA suggesting that EF classes have
promoted the maintenance of the aptitude of these students, except for the speed
obtained in the CPTE in both thresholds that are presented higher for GA.
Conclusion: EF classes combined with the systematized training in the counter shift
of adolescent students may have an effect on cardiorespiratory fitness in the
submaximal parameters of male athletes. Regarding the female gender, the groups
presented no differences regarding the submaximal metabolic cardiorespiratory
responses, except for the velocity obtained in the CPTE.
