Characteristics of the intervention procedures and results obtained by the studies analyzed

Author/year	Group division	Intervention group			Group control	Results	Conclusions
		Type	Time	Intensity
Neder et al. 1999	Intervention: 26 Control: 16	Treadmill and exercise bike (Aerobic)	8 weeks; 45 min; 3 times/week;	Not defined	He did not perform any intervention.	↑ Cardiorespiratory fitness ↔ % FEV1–EIB	Short‐term physical exercise improves physical fitness but does not influence EIB.
Matsumoto et al. 1999	Intervention: 8 Control: 8	Swimming (Aerobic)	6 weeks; 30 min; 6 times/week;	125% do lactate threshold.	He did not perform any intervention.	↑ Cardiorespiratory fitness ↓ % FEV 1 –EIB	The drop in FEV1 points to physical exercise as a protective factor for EIB.
Veldhoven et al. 2001	Intervention: 23 Control: 24	Sports training (Concurrent exercise)	12 weeks; 60 min; 2 times/week;	Not defined	He did not perform any intervention.	↑ Cardiorespiratory fitness ↔ % FEV1–EIB	The occurrence of EIB before and after the intervention did not differ between groups.
Natali et al. 2002	Intervention: 16 Control: 16	Swimming (Aerobic)	10 weeks; 45 min; 3 times/week;	85% da MCF	He did not perform any intervention.	↑ Cardiorespiratory fitness ↓ % FEV 1 –EIB	It is suggested that the increase in FVC and MEF is indicative of a reduction in EIB.
Silva et al. 2006	Intervention: 46 Control: 23	Functional circuit (Concurrent exercise)	12 weeks; 90 min; 2 times/week;	Individually monitored	He did not perform any intervention.	↑ Cardiorespiratory fitness ↔ % FEV1–EIB	FEV1 values did not change before and after the intervention.
Faneli et al. 2007	Intervention: 21 Control: 17	Aquatic and terrestrial (Concurrent exercise)	16 weeks; 90 min; 2 times/week;	Individually monitored	Educational program: ABC of asthma.	↑ Cardiorespiratory fitness ↓ % FEV 1 –EIB	Improvement in aerobic fitness and control of dyspnea if a reduction in EIB is obtained.
Sidiropoulou et al. 2007	Intervention: 18 Control: 11	Soccer (Interval exercise)	8 weeks; 60 min; 3 times/week;	80%–90% da MCF	Conventional football exercise without control.	↑ Cardiorespiratory fitness ↓ % FEV 1 –EIB	Systematic exercise program avoids episodes of EIB.
Tahan et al. 2014	Intervention: 10 Control: 10e	Yoga	12 weeks; 60 min; 2 times/week;	Not defined	Practiced yoga	↑ Cardiorespiratory fitness ↓ % FEV 1 –EIB	The practice of physical exercise has beneficial effects on EIB.

Note: MCF = Maxima Cardiac Frequency ↑ increase; ↓ reduction; ↔ No changes. FEV₁ = Forced Expiratory Volume in the first second. ^e = Control Group was asthmatic children without EIB. Taxed = studies that followed the recommendations for EIB assessment.
