...zum Vergleich Häkkinen et al. (2002). Hier wurden Kraftgruppe (2x/Woche Kraftraining -> S-Group) vs. Kombinationsgruppe verglichen (2x/Woche Krafttraining + 2x/Woche Ausdauertraining -> SE-Group).

Deren Fazit:
In conclusion, the present data do not support the concept of the universal nature of the "interference effect" in strength development and muscle hypertrophy when strength training is performed concurrently with endurance training. However, this interference effect may hold true with regard to explosive strength development associated with limited changes in rapid neural activation of the trained muscles. Second, the "interference effect" may also be true when the overall frequency and/or volume of training is higher than in the present study...
