Previous issue date: 2016-02-25 / The present study is composed by four papers with different aims, as follows: 1) Verify the
reliability of the Wingate anaerobic test. 2) Verify the reliability of lactate minimum protocol
with induction of hyperlactatemia individualized by ratings perceived exertion. 3) Verify the
efficiency of a new submaximal protocol for aerobic evaluation, with workloads
determination by ratings perceived exertion, denominated RPE-13, in identify the intensity of
exercise associated at maximal lactate steady state and lactate minimum. 4) Verify the
influence of anodal transcranial direct current stimulation on left temporal lobe in the heart
rate variability and in the running of 3000 meters. The Wingate study had a sample composed
by 15 cyclists that performed three Wingate tests. The lactate minimum study had a sample
composed by 20 university students active physically that performed two times the test. In the
study with RPE-13 the sample was formed by 11 young adults active physically that
performed three tests, the RPE-13, lactate minimum and maximal lactate steady state. Yet, in
the study with anodal transcranial direct current stimulation the sample was composed by 11
amateurs??? runners that performed of the 3000 meters test in two conditions, in the anodal
stimulation and Sham condition (placebo). The tests of Wingate and lactate minimum showed
good reliability. The RPE-13 test showed to be efficient to identify an intensity of exercise
associated at maximal lactate steady state and lactate minimum. Therefore, the transcranial
direct current stimulation changed the heart rate variability, increasing the chronotropic
reserve and improving the performance in running of 3000 meters in mean 10 seconds. / O presente trabalho ?? composto por quatro artigos cient??ficos com diferentes objetivos,
conforme a seguir: 1) Verificar a reprodutibilidade do teste anaer??bio de Wingate. 2)
Verificar a reprodutibilidade do protocolo de lactato m??nimo com a indu????o a hiperlactatemia
individualizada pela percep????o subjetiva de esfor??o. 3) Verificar a efici??ncia do um novo
protocolo subm??ximo de avalia????o aer??bia, com cargas determinadas pela percep????o
subjetiva de esfor??o, denominado RPE-13, em identificar a intensidade de exerc??cio associada
ao m??ximo estado est??vel de lactato e lactato m??nimo. 4) Verificar a influ??ncia da estimula????o
transcraniana por corrente cont??nua an??dica sob o lobo temporal esquerdo sobre a
variabilidade da frequ??ncia card??aca e no desempenho em teste de corrida de 3000 metros. O
estudo com Wingate teve uma amostra composta por 15 ciclistas que realizaram tr??s testes de
Wingate. O estudo com lactato m??nimo teve uma amostra composta por 20 estudantes
universit??rios fisicamente ativos que realizaram o teste duas vezes. No estudo com o
protocolo RPE-13 a amostra foi formada por 11 adultos jovens fisicamente ativos que
realizaram tr??s testes, o RPE-13, lactato m??nimo e m??ximo estado est??vel de lactato. J?? no
estudo com estimula????o transcraniana por corrente cont??nua a amostra foi composta onze
corredores recreacionais que cumpriram o teste de 3000 metros em duas condi????es, na
condi????o com estimula????o an??dica e na condi????o Sham (placebo). Os testes de Wingate e
lactato m??nimo apresentaram boa reprodutibilidade. O teste RPE-13 se mostrou eficiente em
identificar uma intensidade de exerc??cio associada m??ximo estado est??vel de lactato e lactato
m??nimo. Por sua vez, a estimula????o transcraniana por corrente cont??nua modificou a
variabilidade da frequ??ncia card??aca, aumentando a reserva cronotr??pica e melhorando o
desempenho do teste de corrida de 3000 metros em m??dia em 10 segundos.
