“…Consequently, a lower Bla for a given v is possible and swimming in a 25-m pool would be less strenuous as compared to 50-m pool swimming. It should also be noted that exercise specific factors such as the duration of workload and whether the exercise was continuous or discontinuous could affect the Bla response to exercise [9,14,24,27,29,31]. This means that both lactate production and lactate accumulation accelerate as the exercise distance lengthens or resting intervals during exercise bouts shorten.…”

“…In this study, each 200-m swim in the short course included more than a half less of stroking distance on each pool length before the next turn as compared to the long course. Keskinen et al [14] found that a slight increase of 0.5 mmol • l -1 in Bla concentration (2 mmol • l -1 level) in the n × 100-m test, 3 mmol • l -1 level in the n × 300-m test, and Bla of 4 mmol • l -1 in the 2 × 400-m test occurred at the same swimming velocity (v), which was considered a common reference point for these three exercise modes and the anaerobic threshold. In the heart rate (HR) vs. v comparison, the HR was higher in the n × 300 m and 2 × 400 m tests than in the n × 100-m test in the same v. In the HR vs. Bla comparison, the HRs were approximately the same at corresponding Bla values in the n × 100-m, n × 300-m, and 2 × 400-m tests.…”

Exercise testing in water has been used to follow the progression of conditioning during regular training in swimmers. The present study examined the effects of pool length in eleven male swimmers on a set of 5 x 200-m freestyle swims with increasing speed from submaximal to maximal. Mean velocity of swimming, blood lactate and heart rate were examined in both 25-m and 50-m pools. Turning benefit as a marker for turning skill was measured separately by a underwater video system (speed difference between pre- and post-turning) during short all-out swims. Maximum force during swimming was measured in tethered swimming and explosive strength of leg extensor muscles was evaluated by a counter movement jump. The significantly higher (p=0.033 - 0.000) blood lactate values for the 50-m pool as compared to the 25-m pool were found at each point of swimming velocity versus blood lactate curve. The highest post-test lactate level was 7.36 +/- 1.47 mmol x l (-1) in the short course and 8.24 +/- 1.55 mmol x l (-1) (p=0.033) in the long course. The maximum swimming velocity was significantly greater (4.5 %) in the 25-m pool swimming (1.38 +/- 0.11 m x s (-1) vs. 1.32 +/- 0.12 m x s (-1); p=0.000). The heart rate values were significantly (p=0.020 - 0.000) lower in the short course than in the long course at all points of submaximal velocity with a mean difference of 7.3 +/- 0.7 bpm. Heart rate was equal (172 +/- 14 vs. 172 +/- 14 bpm) after the maximum swims in both short and long course. The turning benefit in the short maximum swim was 0.12 +/- 0.05 m x s (-1) (8.1 +/- 3.2 %), correlating positively with the difference in maximal swimming velocity between the short and long-pool swims (r = 0.59; p = 0.029), with the maximum force during tethered swimming (r=0.75; p=0.004) and with the vertical jumping height in the counter movement jump (r=0.55; p=0.039). We conclude that the pool length has a strong effect on blood lactate concentration and heart rate with greater swimming velocity in the short course pool.

ABSTRACT:The aim of this study is to examine the effects of two months swimming training on aerobic and anaerobic capacities with blood lactate. A total of 17 adolescent male swimmers (15.17±0.81 years) were included in the study. The first measurement was conducted 1.5 months after the beginning of the season and this was followed by a second measurement conducted two months after the first measurement. A test protocol of 8x100 m crawl style was applied in the measurements and the subjects swam from slow to fast at five different swimming workloads. Between each training run, blood samples were provided from the earlobes of the subjects in order to measure the amount of blood lactate. Heart rate was measured after five swims. Furthermore, swimming styles and duration were recorded in order to calculate the swimming speed of each subject at each swimming workload. The comparison of blood lactate and speed values of all subjects before and after the training season revealed that lactate acid values had not changed significantly (p>0.05) at the lowest swimming workload (75%) and that the speed had significantly increased (p<0.01). As for the rest of the swimming workloads, both lactate acid and speed increased significantly (p<0.05 and p<0.01). Our two month training programme dwelt heavily upon anaerobic training and accordingly aerobic capacity decreased and anaerobic capacity increased at higher speeds. On the other hand, in our study, we found out that anaerobic capacity had not increased only at the 75% workload and that it had decreased at the rest of the workloads. There are many test protocols pertaining to swimming which depend on blood lactate and swimming speed measurements. [20,27,32].

“…O treinamento da endurance aeróbica tem a fi nalidade de aumentar a contribuição do metabolismo aeróbico (COS-TILL, 1991;ISSURIN, 2001;TREFFENE, 1981) permitindo uma velocidade de lactogênese diminuída. (CUNHA, 2000;ISSURIN, 2001;KESKINEN, 1989). Na natação, são utilizados com frequência dois protocolos para determinar a velocidade do treinamento: o primeiro proposto por Mader (1976) é um teste intervalado denominado de teste de duas velocidades (2V), que se caracteriza por nadar duas vezes 400 metros, sendo elas a 85% e 100% do tempo pessoal (NISHIBATA, 1993); e o segundo, um teste contínuo denominado T30 (OLBRECHT, 1984) que consiste em nadar 3000 metros de forma uniforme e constante a 100% da velocidade máxima para a distância (BABER, 1997).…”

Fitness & Performance Journal, v.2, n.2, p.75-80, 2003. Canal de Marapendi, 1680/1001 -Barra da Tijuca -Rio de Janeiro -RJ RESUMO: A prescrição do treinamento envolve vários fatores incluindo a necessidade da avaliação da intensidade do treino. No presente estudo, comparamos o teste de duas velocidades (2V) e o teste T30 (T30) para identifi car a melhor velocidade indicada na prescrição de treinamento intervalado de distâncias curtas e longas em atletas de natação da categoria juvenil. Trinta e cinco atletas (22 homens), de 16 anos, foram avaliados antropometricamente, laboratorialmente, e submetidos ao teste 2V e ao T30 para determinar a prescrição da velocidade do treinamento de endurance. Após a determinação da velocidade indicada pelo método, foram estudados protocolos diferentes (25 a 1000 m, todos com percurso de 2000 m). Para cada teste e protocolo, foram mensuradas: a frequência cardíaca máxima e de recuperação, percepção ao esforço, efi ciência mecânica e lactacidemia. Os achados mostraram diferença signifi cativa na velocidade entre os testes 2V (1,36 ± 0,07 m/s), T30 (1,21 ± 0,12), e entre os protocolos houve diferença nas concentrações de lactacidemia na maioria dos percursos (exceto para 200m). Além da determinação da intensidade, foi demonstrada a importância de uma avaliação complementar, facilitando o controle do treinamento diário (frequência cardíaca, efi ciência mecânica e percepção ao esforço), que apresentou diferenças signifi cativas para os testes e protocolos avaliados. Não encontramos quaisquer diferenças em quaisquer parâmetros entre os homens e mulheres estudados. Nossos dados demonstram que os protocolos de 40 x 50m e de 20 x 100 m do teste de duas velocidades são os mais adequados para a prescrição do treinamento em nossas condições.Palavras-chave: treinamento, lactacidemia, endurance, atletas. 75-80
