“…The correlations between total work done and peak blood lactate were low and nonsignificant for all laboratory tests, A similar result was obtained with the data collected in the field. These results support the findings of Ohkuwa and Miyamura (27), who examined the relationship between peak blood lactate and 400-rn sprinting times. On the other hand, Fujitsuka et al (11) demonstrated significant correlations between peak blood lactate and 100-rn (-0.65), 200-rn (-0.78), and 400-rn (-0.79) sprint running.…”

The specificity of three maximal cycling sprint tests as a measure of anaerobic lactacid capacity was determined in nine highly trained male cyclists when they performed 10-, 30-, 40-, and 60-s tests on a modified Repco wind-braked cycle ergometer. Peak power (PP), percent power loss (% PO), total work done (TW), and peak blood lactate (PHLa) were determined for each test. The cyclists also performed a 1000-m time trial under competition conditions during which 200-m split times, total time (TT), and peak post-competition blood lactate (TTPHLa) were recorded. While there was no statistically significant difference between the peak blood lactate of the 30-, 40-, and 60-s tests, peak blood lactate achieved after the 1000-m time trial was significantly greater than those after the cycle ergometer tests. Although there were high intercorrelations (0.88-0.99) between the anaerobic power and capacity indices of the laboratory tests, only the PP and TW achieved during the 60-s test correlated significantly (P less than 0.05) with TT. The data suggest that when assessing the anaerobic power and capacity of elite 1000-m time trial cyclists, a cycle ergometer test duration of at least 60 s should be employed.

“…In the analysis, uneven weights were found in the relationships between the [La] and the distances ran with no significant correlations between the Dmax 30 and [La] max 30 (r = -0.44; p < 0.05), and significant association between the Dmax 60 at the [La] max 60 (r = -0.82; p < 0.05). This last figure can be fitted in the higher level found by other authors, with competitive performance in 400/800 s running and 30-60 s duration treadmill running (r between -0.67 and -0.89) (18)(19)(20)(21)(22) . Despite the limitations of the size of the sampling in the present study, the higher value of the association between Dmax 60 and the [La] max 60 is in accordance to the theoretical model proposed, stating that the max 60 is more dependent from the AnA than the max 30 , and it can be more adequate to deplete it.…”

The anaerobic ability (AnA) is given by the sum of the alactic and lactic (AlA) ability. The cycloergonometer has been used at the maximal 30-second strength (max 30 ) to the AnA approach (mean power and fatigue index). Presently, the AnA is not directly measured, and it is required an operational approaching, such as the measurement of the performance and the blood lactate concentration ([La]). In high-level velocity runners, it is expected that on long-endurance, that is, 60 seconds (max 30 ) strength there would be a higher AnA demand, and aiming the ecological validity, it must be applied on the track. The purpose of this study was to make a comparison between the derived variables of the (max 30 ) and (max 60 ) in runners. Eight male national and international 19-27 years old athletes were submitted to max 30 and max 60 running tests on an official synthetic track, where it was performed an arterialized blood collection from the ear lobule immediately 1, 3, 5, 7.5, and 10 minutes after the strength. To make a comparison between the max 30 and the max 60 , it was used the t-Student test and the simple Pearson's correlation to check the association between variables. The lactate concentrations were significantly higher at max 60 than at max 30 (20.9 ± 1.2 vs. 18.2 ± 1.9 mM, p < 0.05). Oppose to this, the mean velocities were significantly lower (7.9 ± 0.2 vs. 9.1 ± 0.2 m.s -1 , respectively). Significant correlations were found between max 30 and max 60 (r = 0.92; p < 0.05). However, it was not seen the same as to the lactate (r = 0.62; p > 0.05). According to these athletes' characteristics, who are highly tolerant to elevated [La], the derived test variables with duration/distance close to the 60 s/500 m seem to be more adequate as AnA indexes.

O grau de desenvolvimento das capacidades físicas no futebol é fator determinante do nível desportivo do jogador. O objetivo do presente estudo foi comparar valores de limiar anaeróbio e consumo máximo de oxigênio entre jogadores profissionais de futebol de diferentes posições. Para tanto, 25 atletas (idade = 22,08 ± 8,28 anos, peso = 76,12 ± 9,8kg, altura = 179,8 ± 7,1cm e relação corporal = 12,21 ± 3,67% de gordura corporal) foram divididos em cinco grupos, como se segue: goleiros (GO), zagueiros (ZA), laterais (LA), meio-campistas (MC) e atacantes (AT). O VO2max foi determinado em esteira ergométrica através de análise direta e a velocidade de corrida correspondente ao limiar anaeróbio fixo de 4mM (V4mM), em teste de campo (2 x 1.000m a 90 e 95% da velocidade máxima para a distância) através de interpolação linear. A V4mM foi menor (p < 0,05) para o grupo GO em relação aos demais grupos. Além disso, os grupos LA e MC apresentaram valores de V4mM significantemente maiores em relação aos grupos ZA e AT. O grupo GO mostrou VO2max significantemente menor em relação a todos os outros grupos, sendo que estes últimos não apresentaram diferença entre si. Uma vez que os atletas de diferentes posições não realizavam treinamento diferenciado, os autores creditam as diferenças encontradas à especificidade da movimentação durante partidas e coletivos.
