“…In the present study only two coordinates to calculate CV were used, agreeing with previous studies (de Lucas et al, 2012;Pacheco et al, 2006;Penteado et al, 2014;Silva et al, 2005;Simões et al, 2005). Several studies have shown that two coordinates are enough to determine CV in adult trained runners (de Lucas et al, 2012;Simões et al, 2005), moderately trained adults (Smith, Kendall, Fukuda, Cramer, & Stout, 2011), physically active adults (Pacheco et al, 2006;Silva et al, 2005), adult cyclists (Hiyane et al, 2006) and youth swimmers (Altimari et al, 2007). Housh et al (1990), for instance, submitted 12 young adults to four loads until exhaustion and CP was determined with two, three and four coordinates.…”

“…This model does not differ from other models in running (Simões et al, 2005). Only two distances (coordinates) were adopted in order to obtain CV, as previously cited (De Lucas, Dittrich, Junior, de Souza, & Guglielmo, 2012;Pacheco, Silva, Baldissera, Campbell, Liberti, 2006;Penteado et al, 2014;Silva, Pacheco, Campbell, Baldissera, & Simões, 2005;Simões et al, 2005). The distances were chosen with at least a 5min interval between durations (Housh, Housh, & Bauge, 1990) and allowing a total trial time between 3 and 15 min, as recommended (Greco, 2000;Kranenburg & Smith, 1996).…”

In order to investigate the validity of critical velocity (CV) as a noninvasive method to estimate the lactate minimum velocity (LMV), 25 youth runners underwent the following tests: 1) 3,000m running; 2) 1,600m running; 3) LMV test. The intensity of lactate minimum was defined as the velocity corresponding to the lowest blood lactate concentration during the LMV test. The CV was determined using the linear model, defined by the inclination of the regression line between distance and duration in the running tests of 1,600 and 3,000m. There was no significant difference (p=0.3055) between LMV and CV. In addition, both protocols presented a good agreement based on the small difference between means and the narrow levels of agreement, as well as a standard error of estimation classified as ideal. In conclusion, CV, as identified in this study, may be an alternative for noninvasive identification of LMV.

“…This is probably due to the low emphasis given to specific aerobic training. 25 The anaerobic contribution to the global energy demand is emphasized when the frequency of rapid stimuli occurs due to accelerated anaerobic glycolysis. 26,27 This response is evident through the blood lactate levels, which can exceed 12 mmol .…”

OBJECTIVE:We hypothesize that in players with better aerobic fitness, lactate production was not inhibited after high-intensity exercise, regardless of the footballer's position on the field. METHOD: Sixty professional male soccer players performed cardiopulmonary exercise tests on an ergometric treadmill; respiratory gas exchanges were monitored throughout and blood lactate levels at peak effort was measured, using a portable device. The heart rate response was determined by computerized EKG. Training sessions took place over an average of ten hours per week, and the players had 6.8 years of experience in competitive soccer; they were tested a third of way into the season. The positions tested were (centerback, fullback, midfielder and striker). RESULTS:The following results (mean ± std. dev.) were obtained: (1) peak oxygen consumption of 58.8 ± 4.5 ml.kg -1.min. ; (6) percentage of oxygen consumption in the second ventilatory threshold of 84 ± 6%. There was no correlation between maximum aerobic level vs. peak lactate concentration (r = -0,031; p = 0.812), nor between submaximal aerobic level vs. peak lactate concentration (r = -0.146; p = 0.335) in the positions tested. CONCLUSION: Better or worse aerobic profiles according to game positions in soccer players do not influence peak lactate levels following high-intensity exercise, and confirms the study hypothesis.

“…Isso pode ser justificado em função da vVO 2 max representar tanto a participação do metabolismo aeróbio como do anaeróbio o que 694 poderia explicar a maior relação com a performance de provas de média distância (1,5 km e 3 km), visto que 16 % da energia utilizada durante o exercício realizado na vVO 2 max é derivada do metabolismo anaeróbio (FAINA et al, 1997 max com corredores moderadamente treinados, verificando que houve correlação dessa variável com a distância tanto no pré (r = -0,76) quanto no pós treinamento (r = -0,81). Mesmo para indivíduos ativos é possível obter uma boa predição de performance por meio da vVO 2 max com a distância de 3 km (r = 0,91), que pode ser constatado no estudo realizado por Silva et al (2005). Por outro lado, Lacour et al (1990), além de verificarem correlação da vVO 2 max com a velocidade média de 1,5 km (r = 0,62) e 3 km (r = 0,64), também observaram correlação com a performance de 5 km (r = 0,86).…”

IntroduçãoVários estudos têm procurado determinar os índices fisiológicos capazes de predizer a performance aeróbia e que, também, possam ser utilizados como referência para prescrição e controle dos efeitos do treinamento (BRANDON, BOILEAU, 1987;BRANDON, 1995;DENADAI, 1996;DENADAI;ORTIZ; MELLO, 2004).Tradicionalmente, os índices aeróbios mais estudados para a predição da performance durante as corridas de endurance são o consumo máximo de oxigênio (VO 2 max), a velocidade correspondente ao VO 2 max (vVO 2 max), o tempo de exaustão na vVO 2 max e a economia de corrida (EC) (DENADAI, 1996;DENADAI;ORTIZ; MELLO, 2004;BILLAT et al., 1999;DENADAI, 1999).Embora o VO 2 max seja o parâmetro fisiológico que melhor expressa a aptidão cardiorrespiratória do indivíduo (BASSETT;HOWLEY, 2000), o mesmo apresenta um baixo poder discriminatório da performance em um grupo homogêneo de corredores (DENADAI; ORTIZ: MELLO, 2004). Por outro lado, a velocidade correspondente ao VO 2 max (vVO 2 max) é um índice determinante para a predição de performance em provas de média e longa duração (NOAKES; MYBURGH; SCHALL, 1990). Sobretudo, porque este índice Motriz, Rio Claro, v.18 n.4, p.690-698, out./dez. 2012 Artigo OriginalÍndices fisiológicos associados com a performance aeróbia de corredores nas distâncias de 1,5 km, 3 km e 5 km Physiological indices associated with aerobic performance in the distances of 1,5 km, 3 km and 5 kmAbstract: The aim of this study was to analyze the association between physiological indices of aerobic power and aerobic capacity with the performance in the distances of 1.5 km, 3 km and 5 km. Nine endurance runners performed the following protocols: a) test to determine the VO 2 max, vVO 2 max and OBLA; b) 2-5 tests in alternate days of 30 minutes with constant speed to determine the vMLSS; and c) performances (P). The linear correlation of Pearson or Spearman and multiple regression were applied to determine the relationships among the indices and the performance. It was found a significant correlation only of the vVO 2 max with the performance of 1.5 km (r = 0.78) and 3 km (r =0.81). Thus, it can be suggested the inclusion of training sessions at or near vVO 2 max on weekly periodization. Based on the present findings, it can be concluded that the performance prediction through the indices of power and aerobic capacity depend on the distance and duration of the race.
