Fernando Klizke Borszcz, Artur Ferreira Tramontin

Resumo


Objetivo: verificar o efeito sobre a medida de potência durante um bloco concentrado de treinamento intervalado de alta intensidade por meio de sprints all out em ciclistas treinados. Métodos: 10 ciclistas treinados (VO2max 61 ± 5 ml/Kg/min; 33 ± 11 anos; 177 ± 5 cm; 75 ± 6 Kg), realizaram inicialmente um teste incremental, logo após realizaram 7 dias consecutivos de treinamento intervalado de sprints all out. As sessões de treino consistiram em 10 sets de 3 sprints de 15, 30 e 45 segundos separados por pausas na proporção 1:5. A medida de potência das sessões de treino foi aferida nos dias 1, 4 e 7. Resultados: ao longo da semana não houve diferença nas potências média (PM) e pico (PP) entre os dias 1, 4 e 7 (p < 0,05). Durante todas as sessões a PM e PP dos sprints de 15 segundos foram significativamente maiores as dos sprints de 30 (p = 0,03) e 45 segundos (p < 0,0001), porém não houve diferença entre os sprints de 30 e 45 segundos.  Para os dez sets de sprints houve superiodade dos 2 primeiros sets aos demais para a PP (p = 0,03), para a PM os 3 sets iniciais foram superiores aos demais (p = 0,03). Conclusão: este estudo demonstrou que durante 7 dias consecutivos de treinamento intenso por meio de sprints all out não houveram mudanças significativas na produção de potência durante sessões de treino.

 

ABSTRACT

Block sequencing: effects on power output during all-out sprints in trained cyclists

Objective: verify the effects of a concentrated block training of high-intensity interval training over the power responses in trained cyclists. Methods: 10 trained cyclists (VO2max 61 ± 5 ml/Kg/min; 33 ± 11 years; 177 ± 5 cm; 75 ± 6 Kg), performed an incremental test, followed by a consecutive 7-day period of high-intensity interval training of all-out sprints. The training sessions consisted of 10 sets of 3 sprints with 15, 30 and 45 seconds separated by pauses of a 1:5 proportion. Power output measures were made at days 1, 4 and 7. Results: Through the week, no differences were seen in mean power (MP) and peak power (PP) between days 1, 4 and 7 (p < 0,05). During all sessions, the MP and PP of the 15-second sprints were significantly higher than the 30 (p = 0,03) and 45 seconds (p < 0,0001), however, there were no differences between 30 and 45-second sprints. For the ten sets of sprints the PP was higher in the 2 first sets (p = 0,03), for MP, the 3 initial sets were higher than the others (p = 0,03). Conclusion: the present study showed that during a 7 day period of intense training of all out sprints there were no significant differences in the power output during the training sessions.
