Exercise-Induced Bronchoconstriction and Exercise-Induced Respiratory Symptoms in Nurses

Table 5

Characteristics of the ECT in nurses and controls.

Variable	Nurses	Controls
	(𝑛=48)	(𝑛=48)
Exercise load (Watt)	102.1±20.3	106.3±16.1
Positive ECT	4 (8.3%)	3 (6.3%)
ΔFEV1 in the subjects with EIB (%)	28.1±3.4	22.7±1.5
Time of EIB occurrence; (minutes after exercise)	6.1±2.1	6.9±2.7

Numerical data are expressed as mean value with standard deviation and frequencies as number and percentage of study subjects with certain variable.
ECT: exercise challenge test; ΔFEV₁: a fall in FEV₁ of pre-exercise value; FEV₁: forced expiratory volume in 1 second; EIB: exercise-induced bronchoconstriction.
