Key result
Mean exercise intensity at 4 mmol/L lactate on a swim bench strongly correlated with fourth quarter blood lactate (r=-0.82, P=0.01) and heart rate (r=-0.93, P<0.001) during water polo game-playing.
Why the study?
Does submaximal metabolic response to swim bench exercise correlate with metabolic responses during water polo game-playing in female water polo players?
Observational (n=8)
Does submaximal metabolic response to swim bench exercise correlate with metabolic responses during water polo game-playing in female water polo players?
Effect estimate: r=-0.93 for heart rate; r=-0.82 for blood lactate
p-value: p=<0.001
Submaximal metabolic responses to exercise on a swim bench are closely correlated with metabolic responses to water polo game-playing in female athletes.
May link dry-land responses to water polo play; hypothesis-generating and requires larger prospective validation.
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.

Konstantaki et al. (1998) conducted an observational in Water polo players (n=8). Swim bench exercise vs. Water polo game-playing was evaluated on Correlation between exercise intensity at 4 mmol/L lactate on a swim bench and fourth quarter blood lactate and heart rate during game-playing (r=-0.93 for heart rate; r=-0.82 for blood lactate, p=<0.001). Mean exercise intensity at 4 mmol/L lactate on a swim bench strongly correlated with fourth quarter blood lactate (r=-0.82, P=0.01) and heart rate (r=-0.93, P<0.001) during water polo game-playing.
