SILVA, D.F. da; SOTERO, R.C.; SIMOES, H.G.  and  MACHADO, F.A.. Maximal aerobic speed calculated by heart rate cost: relationship with performance. Rev Andal Med Deporte [online]. 2015, vol.8, n.1, pp.7-15. ISSN 2172-5063.  https://dx.doi.org/10.1016/j.ramd.2014.06.001.

Objectives: To compare maximal aerobic speed (MAS) calculated by oxygen cost (vVO_2max) and heart rate cost (vHR_max) with the direct measurement of MAS (V_peak) and to verify the relationship between vHR_max and 10- and 15-km performance in middle-age recreationally runners. Method: Twenty one recreationally runners participated in this study (age: 30 to 49 years), allocated in two groups according to age (G1 and G2). Participants were submitted to an incremental continuous test of maximal effort in laboratory to determine maximal oxygen uptake. MAS was determined according to proposes presented in literature based on vVO_2max and vHR_max. Besides, it was performed two performances in field track (10 and 15 km). Results: The lowest difference between the mean values observed and V_peak was in relation to vHR_max from Lacour et al. (0.0 km h^-1; p > 0.05). The highest was in relation to vHR_max from di Prampero (1.55 km h^-1; p < 0.05). The same pattern of differences was observed when G1 and G2 were analyzed. The vHR_max determined according to two different methods presented in literature showed to be correlated with 10 and 15 km performances (0.55 ≤ r ≤ 0.82; p < 0.05). Conclusions: The vHR_max in middle-aged recreational runners has elevated correlation with 10 and 15 km performances and was not different from V_peak (to vHR_max from Lacour et al.) showing similar results than the method based on oxygen cost.
