The purpose of this study was to investigate the acute physiological responses of interval protocols using the minimal power output (MAP) that elicits peak oxygen uptake (V[Combining Dot Above]O2peak) as exercise intensity and different durations of work intervals during intermittent cycling. In randomized order, 13 well-trained male cyclists (V[Combining Dot Above]O2peak = 67 ± 6 ml·kg·min) performed 3 different interval protocols to exhaustion. Time to exhaustion and time ≥ 90% of V[Combining Dot Above]O2peak were measured with MAP as exercise intensity, and work duration of the intervals equals either 80% of Tmax, 50% of Tmax, or 30 seconds with recovery period being 50% of the work duration at intensity equal to 50% of MAP. The major findings were that the interval protocol using 30-second work periods induced longer time ≥90% of V[Combining Dot Above]O2peak and longer work duration at MAP intensity than the interval protocols using work periods of 50% of Tmax or 80% of Tmax (p ≤ 0.05). There was no difference between the protocols using work periods of 50% of Tmax or 80% of Tmax. In conclusion, the present study suggests that the 30-second work interval protocol acutely induces a larger exercise stimulus in well-trained cyclists than the protocols using work periods of 50% of Tmax or 80% of Tmax. The practical application of the present findings is that fixed 30-second work intervals can be used to optimize training time at MAP and time ≥90% of V[Combining Dot Above]O2peak in well-trained cyclists using MAP exercise intensity and a 2:1 work:recovery ratio.

“…Accordingly, reducing the recovery periods by one-half (i.e. 15 s) during a protocol with 30 s work intervals seems to increases running time ≥ 90% of VO2peak(30). Moreover, in neither of the abovementioned studies were the interval protocols performed until exhaustion(26,30) Billat et al (2000).…”

“…Several studies have examined acute VO 2 and/or HR responses during either continuous or short intermittent runs at maximal and/or supramaximal aerobic velocities (i.e. at velocities equal or greater than the velocity at which VO 2 max is achieved) during the developmental years (Baquet et al 2002a, b;Berthoin et al 2003;Tardieu-Berger et al 2004;Thevenet et al 2007aThevenet et al , b, 2008, as well as, in adulthood (Hill and Rowell 1997;Billat et al 1999aBillat et al , 2000Millet et al 2003a, b;Dupont et al 2002;Rozenek et al 2007;Wakefield and Glaister 2009). However, there are a few studies on long-interval exercise protocols that examined acute VO 2 responses, and these studies were performed in adults (Demarie et al 2000;Millet et al 2003a).…”

This study compared the physiological responses to heavy continuous (HC), short-intermittent (SI), and long-intermittent (LI) treadmill exercise protocols in non-endurance adolescent males. Nine adolescents (14 +/- 0.6 years) performed a maximal incremental treadmill test followed, on separate days, by a SI [30 s at 110% of maximal aerobic velocity (MAV) with 30 s recovery at 50%], a LI (3 min at 95% of MAV with 3 min recovery at 35%), and a HC (at 83% of MAV) aerobic exercise protocol. VO(2) and HR were measured continuously, and blood samples were obtained prior to and after the protocols. The duration of exercise and the distance covered were longer (p < 0.05) in HC and LI versus SI. All participants reached 80 and 85% of VO(2)peak irrespective of the protocol, while more participants reached 90 and 95% of VO(2)peak in the intermittent protocols (9 and 6, respectively) versus HC (5 and 3, respectively). The time spent above 80 and 85% of VO(2)peak was higher in HC and LI versus SI; the time above 90% was higher only in LI versus SI, and the time above 95% was higher in LI versus HC and SI. The total VO(2) consumed was greater in HC and LI versus SI. Lactate was higher after LI versus HC. In conclusion, when matched for exhaustion level, LI is more effective in stimulating the aerobic system compared to both HC and SI, while HC aerobic exercise appears equally effective to SI. Nevertheless, adolescents have to exercise for a longer time in HC and LI to achieve these effects.

“…Nossos resultados demonstraram um efeito da intensidade no Tlim (ver tabela 1), corroborando com outros estudos, que também encontraram um maior tempo de exercício e quantidade de séries executadas quando a intensidade era relativamente menor (DUPONT et al, 2002;THEVENET et al, 2007). Esta resposta poderia ser explicada pela menor contribuição do sistema anaeróbio na ressíntese do ATP (ROZENEK et al, 2007), o que provavelmente diminuiria a produção e acúmulo de metabólitos responsáveis pela instalação da fadiga e conseqüente interrupção do exercício (ver tabela 1). Portanto, para manter mais tempo em t95VO 2 max, é necessário uma intensidade intermediária (110%vVO 2 max) no qual alcance o VO 2 max em um tempo reduzido e ainda consiga executar em torno de 15 séries de esforço.…”

IntroduçãoO consumo máximo de oxigênio (VO 2 max) é definido como a maior quantidade de oxigênio que pode ser captada do ar ambiente, transportada e utilizada pelas células durante a atividade física (HILL e LUPTON, 1923;HAWKINS et al., 2007). Dentre as características fisiológicas encontradas em atletas, o VO 2 max é um dos mais relevantes para determinar a eficiência do sistema cardiorrespiratório, e um importante indicador do desempenho para atletas de provas com alta demanda do sistema aeróbio, como as corridas de fundo e meio fundo no atletismo (BRANDON, 1995; MIDGLEY, MCNAUGHTON e WILKINSON, 2006; MIDGLEY, MCNAUGHTON e JONES, 2007 Motriz, Rio Claro, v.19 n.1, p.207-216, jan./mar. 2013 Effect of intensity of intermittent running exercise 30s:15s at the time maintenance at or near VO 2 maxAbstract: The present study compared the time maintained above 90% (t90VO 2 max) or 95% VO 2 max (t95VO 2 max) in three different exercise intensities. After performing an incremental test to determine VO 2 max, eight physical education active students (23 ± 3 years) performed three intermittent exercise sessions (100, 110 e 120% velocity of VO 2 max (vVO 2 max)) with ratio effort:recovery of 30s:15s. The t95%VO 2 max was significantly higher at 110%vVO 2 max (EI 110% ) (218.1 ± 81.6s) compared to 100% vVO 2 max (EI 100% ) (91.9 ± 75.2s) and 120%vVO 2 max (EI 120% ) (126.3 ± 29.4s), but without differences between EI 100% and EI 120% . The t90%vVO 2 max was significantly different only between EI 110% and 120%. Therefore, we conclude that during intermittent exercise with ratio 30s:15s, the intensity of 110%vVO 2 max appears more appropriate to maintain VO 2 max for a longer time.
