Effect of transition from land into a prone swimming body position in water onspirometry findings in 14 elite competitive swimmers. The effect is calculated as percent ofthe measured change out of the initial value measured on land

	Female swimmers N=7	Male swimmers N=7	p-value
FEV1 decrease in transition into water %	6.3 (3)	7.7 (3)	0.42
FVC decrease in transition into water %	1.3 (4)	6.2 (4)	0.04*
FEV1/FVC decrease in transition into water %	5.3 (3)	2.2 (5)	0.17
MVV decrease in transition into water %	6.8 (4)	6.6 (5)	0.71
cMVV decrease in transition into water %	6.3 (3.2)	7.9 (3.2)	0.36
