8.5 Endurance training Modality
The endurance training modality employed in a concurrent training regime may also modulate interference following long-term concurrent training.Interestingly,the majority of concurrent training studies reporting an interference effect have incorporated running,and less often cycling,as the endurance training modality.It remains unclear what might account for any mode-specific interference effect,although it has been suggested thatthis may relate to the similarity between cycling and many strength outcome measures and/or the greater eccentric muscle damage induced by running compared with cycling.Whether running exercise has the capacity to induce greater catabolic molecular activity and/or exacerbate residual neuromuscular fatigue in contrast to cycling,which may in turn exacerbate interference, is currently unclear.Relately little is known regarding the impact of running exercise on acute post-exercise adaptive impact of running exercise on acute post-exercise adaptive response in skeletal muscle compared with cycling.Indeed,no studies performed to date have examined the molecular responses to concurrent exercise incorporating running as the endurance training modality. Given that the majority of term-sport athletes(e.g. australian football,soccer,rugby,etc) employ running as the predominant endurance training in recreational concurrent traning regimes further work is required to examine the potential consequences of the endurance exercise modality on acute molecular interference and subsequent long-term adaptation to concurrent training.
