Abstract

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 1-1), 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 1-1 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 ( sx ) 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.
