O estudo foi composto por 55 adultos jovens de 18 a 36 anos recrutados de modo voluntário e em seguida aleatorizados em três grupos: HIIT-T (n = 17); HIIT-C (n = 19); e CONT, o qual serviu de grupo controle (n = 19). Os grupos HIIT-T e HIIT-C realizaram 8 séries de esforço de 20 s com intensidades de 130% da velocidade associada ao consumo máximo de oxigênio (vVO2máx) e all-out, respectivamente, alternadas com 10 s de recuperação passiva, ao passo que o CONT treinou 30 min entre 90-95% da frequência cardíaca (FC) correspondente ao segundo limiar ventilatório (LV2), todos com três sessões semanais. Antes e após o programa, os sujeitos foram avaliados quanto as variáveis cardiorrespiratórias: consumo máximo de oxigênio (VO2máx) e VO2 e FC correspondentes ao LV2, assim como economia de corrida (ECO) em velocidade submáxima. Ainda, foram mensuradas variáveis neuromusculares, a saber: amplitude eletromiográfica máxima (EMG) e submáxima (EMG50) dos músculos reto femoral (RF), vasto lateral (VL) e deltoide anterior (DA) em teste de contração isométrica voluntária máxima (CIVM), assim como a potência máxima (POT) absoluta e relativa e a altura de salto nos saltos contramovimento (CMJ) e agachado (SJ) e a taxa de desenvolvimento da força (TDF) média e pico no salto CMJ. Observaram-se incrementos significativos no VO2máx (HIIT-T: 20,25%; HIIT-C: 15,85%; CONT: 22,29%), vVO2máx (HIIT-T:12,66%; HIIT-C: 6,10%; CONT: 13,40%), LV2 (HIIT-T: 21,80%; HIIT-C: 12,29%; CONT: 14,74%), ECO (HIIT-T: 7,14%; HIIT-C: 13,36%; CONT: 5,42%), altura de salto CMJ e SJ (HIIT-T: 8,53 e 3,06%; HIIT-C: 6,41 e 10,40%; CONT: 2,18 e 4,37%, respectivamente), POT absoluta no salto SJ (HIIT-T: 1,68%; HIIT-C: 6,35%; CONT: 0,51%), POT relativa nos saltos CMJ e SJ (HIIT-T: 3,88 e 1,23%; HIITC: 3,10 e 4,83%; CONT: 0,58 e 1,85%, respectivamente); TDF média e pico no CMJ tanto em 50 ms (103,34% e 68,20%) e 100 ms (44,53% e 44,61%) respectivamente, todos sem diferenças entre os grupos. Para a vLV2 também foram observadas melhoras em todos os grupos, porém, o HIIT-T melhorou mais (17,19%) em comparação aos demais (HIIT-C: 8,16%; CONT: 14,83%). Quanto a POT absoluta no salto CMJ houve aumento apenas nos grupos HIITT (4,37%) e HIIT-C (4,54%) e não no CONT (-0,75%). Ademais, não houve incrementos na EMG para os músculos RF e VL em nenhum dos grupos em conjunto com uma redução na amplitude EMG no DA. Contrariamente, os resultados de EMG50 revelaram aumento nos músculos RF (HIIT-T: 41,74%; HIIT-C: 16,83%; CONT: 78,40%) e VL (HIIT-T: 30,23%; HIIT-C: 29,46%; CONT: 59,17%) sem diferenças entre treinos e, no DA, a amplitude EMG50 aumentou apenas no grupo HIIT-C (~135%). Conclui-se que os três protocolos são igualmente eficientes para melhora da potência aeróbia máxima, assim como do segundo limiar ventilatório e das forças reativa e explosiva em até 16 semanas de treinamento. Ainda, os treinos não foram capazes de aumentar a amplitude do sinal EMG ao mesmo tempo em que incrementaram a EMG50 nos músculos RF e VL. Por fim, o HIIT-T incrementou mais a vLV2 em esteira, enquanto que o HIIT-C foi o único grupo capaz de melhorar a EMG50 no DA / This study aimed to evaluate and compare the cardiorespiratory and neuromuscular responses to 16 weeks of traditional (HIIT-T) and calisthenic (HIIT-C) high-intensity interval training as well as moderate intensity continuous training (CONT). The sample was composed by 55 young adults aged 18 t 36 years old, recruited voluntarily and randomized into three groups: HIIT-T (n = 17); HIIT-C (n = 19); and CONT (n = 19), which was employed as a controlgroup. HIIT-T and HIIT-C groups performed eight 20 s effort bouts with intensities of 130% vVO2max and all-out, respectively, interspersed with 10 s of passive recovery, while CONT trained 30 min at 90-95 % of the heart rate (HR) corresponding to the second ventilatory threshold (VT2). Before and after intervention the subjects were evaluated for cardiorespiratory variables: maximum oxygen uptake (VO2max); VO2 and HR corresponding to the LV2; as well as running economy (ECO). Furthermore, neuromuscular variables were measured as follows: maximal (EMG) and submaximal (EMG50) electromyographic amplitude for the rectus femoris (RF); vastus lateralis; and anterior deltoid (AD) muscles during voluntary isometric contraction tests and the maximum absolute and relative power (POT) as well as the jump height in the countermovement (CMJ) and squat (SJ) jumps. Average and peak rate of force development (RFD) was also measured in the CMJ. After intervention, there were significant increases in VO2max (HIIT-T: 20.25%; HIIT-C: 15.85%; CONT: 22.29%), vVO2max (HIIT-T: 12.66%; HIIT C: 6.10%; CONT: 13.40%), LV2 (HIIT-T: 21.80%; HIIT-C: 12.29%; CONT: 14.74%), ECO (HIIT-T: 7.14%; HIIT-C: 13.36%; CONT: 5.42%), CMJ and SJ height (HIIT-T: 8.53 and 3.06%, HIIT-C: 6.41 and 10.40%; CONT: 2.18 and 4.37%, respectively), SJ absolute POT HIIT-T: 1.68%; HIIT-C: 6.35%; CONT: 0.51%), CMJ and SJ relative POT (HIIT-T: 3.88 and 1.23%; HIIT-C: 3.10 and 4.83%, CONT: 0.58 and 1.85%, respectively) and also peak and mean CMJ’s RFD at 50 ms (68,20% and 103,34%) and 100 ms (44,61% and 44,53%) respectively, all without differences between groups. Improvements in the vLV2 were also observed for all groups, however, HIIT-T improved more (17.19%) compared to the others (HIIT-C: 8.16%; CONT: 14.83%). The absolute POT in CMJ increased only in HIIT-T (4.37%) and HIIT-C (4.54%) and not in CONT (-0.75%). Furthermore, there were no increases in the EMG for RF and VL in any of the groups, with a reduction in the EMG amplitude for AD. In contrast, EMG50 results showed an increase for RF (HIIT-T: 41.74%; HIIT-C: 16.83%; CONT: 78.40%) and VL (HIIT-T: 30.23%; HIIT-C: 29.46%; CONT: 59.17%) without differences between groups and, in the AD, EMG50 amplitude increased only in HIIT-C (~135%). It can be concluded that the three protocols are equally effective for improving maximal aerobic power, as well as the second ventilatory threshold and reactive and explosive forces up to 16 weeks of training. Also, they were not able to increase the amplitude of the EMG signal while there were improvements in EMG50 for the RF and VL muscles. Finally, to increase the vLV2, HIIT-T is preferred, while HIIT-C was the only group able to improve EMG50 in AD.
