Influence of cycling cadence on subsequent running performance in triathletes

Abstract

The highest cycling cadences (MOC, FCC) contribute to an increase in energy cost during cycling and the appearance of a VO2 slow component during subsequent running, whereas cycling at EOC leads to a stability in energy cost of locomotion with exercise duration. Several hypotheses are proposed to explain these results such as changes in fiber recruitment or hemodynamic modifications during prolonged exercise.

Constant versus variable-intensity during cycling: effects on subsequent running performance

“…high preactivation of lower limb muscles) contributes to the improved running performance in our triathletes when the prior cycling intensity remains constant. Additional variables such as cycling cadence, have been reported to affect subsequent running performance (Bernard et al 2003;Gottshall et Palmer 2002;Hausswirth et al 2001;Vercruyssen et al 2002Vercruyssen et al , 2005. For instance, Gottshall and Palmer (2002) found that higher cycling cadence (>100 rpm), compared to the selection of lower cadences (70-90 rpm), immediately before running increased stride frequency and, as a result, increased running speed.…”

“…To our knowledge, only Ramsay et al (2001) have reported that varying intensity within the range of 20-40% of the average workrate during a 60-min cycle time trial has no effect on subsequent 10-km running compared to a constant cycling bout, in relatively untrained subjects. The previous studies leading to an improved running performance after a constant metabolic load during cycling (Hausswirth et al 1999;Vercruyssen et al 2002Vercruyssen et al , 2005 suggest that the selection of a constant PO would be the best pacing strategy to induce a stability of metabolic responses during cycling and to reduce any decrements in running performance. To date, however, no data are available on the influence of various PO profiles during cycling on subsequent running performance in trained subjects and in outdoor conditions that simulate triathlon racing.…”

“…However, it is important to note that this type of pacing strategy has been derived from cycling exercises conducted in laboratory settings or flat outdoor sessions, without any important changes in topography or wind conditions (Atkinson et al 2003;Perrey et al 2003;Swain 1997). In the context of triathlon field, many studies have investigated the effect of various cycling exercise on subsequent running performance (Bernard et al 2003;Hausswirth et al 1999Hausswirth et al , 2001Vercruyssen et al 2002Vercruyssen et al , 2005. Experimental variables such as cadence (Bernard et al 2003;Vercruyssen et al 2002Vercruyssen et al , 2005 and drafting during the cycling exercise (Hausswirth et al 1999) have been shown to affect subsequent running responses.…”

Características fisiológicas e biomecânicas na corrida do triatlo: uma revisão narrativa

“…Acredita-se que a etapa da corrida é um elemento fundamental aos resultados finais da prova, principalmente nos minutos da etapa do ciclismo (transição ciclismo/corrida), devido aos ajustes posturais e de ativação dos músculos, podendo assim, afetar significativamente o resultado final da prova. 7,8 Evidências indicam que possa haver alterações agudas fisiológicas na corrida após o ciclismo como: maior consumo de oxigênio (VO 2 ), [9][10][11][12][13] pior economia de corrida em atletas de nível médio e melhora na economia de corrida em atletas de elite após o ciclismo.…”
