The aim of this study was to explore the relationship between physiological responses to dry-land testing and to water polo playing. Eight female water polo players (mean+/-s: age 26.7+/-5.7 years, height 169+/-6 cm, body mass 65.3+/-7.0 kg) participated in two assessments. The first involved a discontinuous incremental arm test to exhaustion on an isokinetic swim bench. Blood lactate was determined from finger-prick blood samples and heart rate was recorded at increasing exercise intensities. The highest (peak) values for blood lactate (5.1+/-0.2 mmol l(-1)), exercise intensity (79+/-5.2 W) and heart rate (146+/-6 beats min(-1)) were recorded at exhaustion. Also, the exercise intensity and heart rate at a blood lactate concentration of 4 mmol l(-1) were established. The second assessment involved determination of blood lactate and heart rate immediately after each quarter of a different water polo game for each subject. The mean (+/-s(x)) blood lactate and heart rate for each quarter of the game were as follows: 3.5+/-0.4, 4.3+/-0.5, 4.3+/-0.7 and 4.6+/-0.5 mmol l(-1); 138+/-10, 149+/-12, 151+/-9 and 154+/-8 beats min(-1), respectively. None of the peak values on the swim bench correlated with blood lactate or heart rate responses to game-playing. However, the mean exercise intensity at 4 mmol l(-1) lactate (64+/-5 W) correlated with the fourth quarter values of both blood lactate concentration (r=-0.82, P=0.01) and heart rate (r=-0.93, P< 0.001). These results show that submaximal metabolic responses to exercise on a swim bench are closely correlated with metabolic responses to water polo game-playing.
本研究的目的是探讨旱地测试的生理反应与水球运动之间的关系。八名女子水球运动员（平均±标准差：年龄26.7±5.7岁，身高169±6厘米，体重65.3±7.0千克）参与了两项评估。第一项评估包括在等动游泳训练椅上进行的不连续递增手臂测试直至力竭。通过手指采血样本测定血乳酸，并在运动强度增加时记录心率。在力竭时记录血乳酸（5.1±0.2毫摩尔/升）、运动强度（79±5.2瓦）和心率（146±6次/分钟）的最高（峰值）值。此外，还确定了血乳酸浓度为4毫摩尔/升时的运动强度和心率。第二项评估包括在每位受试者进行一场不同的水球比赛的每一节比赛后立即测定血乳酸和心率。比赛每一节的平均（±标准误）血乳酸和心率如下：分别为3.5±0.4、4.3±0.5、4.3±0.7和4.6±0.5毫摩尔/升；138±10、149±12、151±9和154±8次/分钟。游泳训练椅上的峰值与比赛时的血乳酸或心率反应均无相关性。然而，乳酸浓度为4毫摩尔/升时的平均运动强度（64±5瓦）与血乳酸浓度的第四节值（r = -0.82，P = 0.01）和心率（r = -0.93，P < 0.001）均相关。这些结果表明，在游泳训练椅上进行运动时的次最大代谢反应与水球比赛的代谢反应密切相关。
