DINIZ SILVA, C.; SANTOS CERQUEIRA, M.; GOMES MOREIRA, D.  and  BOUZAS MARINS, J. C.. Reliability of maximum heart rate in match's and comparison with predicted in young soccer players. Rev Andal Med Deporte [online]. 2013, vol.6, n.4, pp.129-134. ISSN 2172-5063.

Objective. To verify the reliability of maximal heart rate obtained (MHR_obt) in official soccer games and to compare it with calculated by equations (MHR_pre). Method. The study included 18 soccer players (14 ± 0.6 years, 174 ± 6 cm, 62 ± 6 kg) participant of a Brazilian state championship in U-15 category. The equations were selected [MHR = age-220]; Tanaka et al. [MHR = 208 - (0.7*age)] and Nes et al. [MHR=211 - (0.64*age)] for comparison with MHR_obt in competition. Results. Bland-Altman analyze showed good agreement of MHR_obt and the CV (1 %) and ICC (0.95 [0.86 - 0.98]) show good reliability of the inter matches. The MHR_obt (202 ± 8 bpm) was lower than 220 - age equation (205 ± 1 bpm; P < 0.05) and higher than Tanaka et al. (198 ± 0.4; P < 0.05), with no difference to the Nes et al. equation (202 ± 0.5 bpm) (P > 0.05). Conclusion. MHR_obt there is good reliability between soccer matches in competition and it is recommended to use the Nes et al. [MHR = 211 - (0.64 * age)] equation to MHR_pre in young soccer players.
