Vergleich des beanspruchungsprofils beim walking, jogging und bei der fahrradergometrie bei unterschiedlich leistungs-fähigen personen

We compared the metabolic and cardio circulatory strain during Walking and Jogging under consideration of the individual training conditions. Besides, we examined whether intensity recommendations on the basis of heart rates (HR) measured during a Cycle Ergometry (CE) are also suitable for a Walking-training. 11 health athletes (HA) [maximal performance (P_max): 2,7 ± 0,6 W·kg^-1] and 13 leisure time athletes (LA) [P_max: 4,5 ± 0,6 W·kg^-1] performed first of all an incremental graded CE. Furthermore, all subjects performed exhaustive field step tests both in Walking and in Jogging to determine the individual anaerobic threshold (IAT). During Walking both HR_max (10% in LA and 7% in HA) and Laktat_max (43% in LA and 32% in HA) were lower than during Jogging. HR at the IAT was also 19 to 17% lower during Walking if compared to Jogging. Mean HR at the IAT_Walkig corresponded both in HA and in LA to mean HR at the IAT_CE, however, individual differences up to 17 min^-1 have to be considered. Although the cardio circulatoric and metabolic strain of Walking is both at maximum and at the IAT lower if compared to Jogging, the IAT of all HA and 11 LA reaches an effective range above of 65% of HR_max. HR_lat of Walking and CE are similar. When calculating walking training heart rates from CE, clear individual discrepancies have to be considered.
