“…The prevalence found in the present study of 38% is greater than that found in the U.S. athletes who participated in the 1984 (11%) (23) and 1996 (17%) (24) Summer Olympic Games. The prevalence found in our study is more than twice that found in high school athletes studied by Kukafka et al (18%) (25). Reasons for these discrepancies may be the method of testing or how EIB/AHR is defined.…”

“…But it requires more space unless it takes place in an indoor gymnasium, is sometimes unavailable in outpatient or public settings and is not reproducible in the community setting [29]. Hence KUKAFKA et al [30] assert that more data are needed on the effectiveness of free running as a "field test" in epidemiological studies in patients with asthma. Conversely, HABY et al [31] consider a 6 min run on a 50-or 100-m track on the flat to have good validity and reliability when performed under appropriate conditions (using noseclips to ensure mouth-breathing and monitoring heart rate to maintain a heart rate of 180 ¡ 10 bpm for the final 4 min of exercise).…”

A simple exercise test would be useful for detecting exercise-induced asthma, a common problem in asthmatic children. The current study compared the 3-min step test with treadmill exercise for evaluating exercise-induced asthma in asthmatic children and assessed whether responses to both tests are influenced by baseline lung function and habitual physical activity.A series of 154 asthmatic children (84 male children; mean age 12.9 ¡ 0.9 yrs) underwent a 3-min step-test and treadmill testing on different days within a week at least 24 h apart. Before both tests each subject did spirometry to obtain the baseline forced expiratory volume in one second (FEV1). After both exercise challenges all subjects did serial spirometry and the lowest FEV1 recorded over time was used to calculate the fall in FEV1 expressed as a percentage of the measured pre-exercise (baseline) value (% fall in FEV1) and the area above the FEV1 curve (AAC 0-30 min ) expressed as a percentage of the pre-exercise value. Changes in both exercise variables were also analysed in percentile subgroups defined by questionnaire answers on habitual physical activity in hours.The mean % fall in FEV1 was significantly higher for treadmill exercise than for the step test (15.0¡7.5 versus 11.7¡5.9); and the AAC 0-30 min was larger for treadmill than for the step test (-261.6¡139.9% versus -197.3¡105.0% min). In all subgroups defined by habitual physical activity the mean % fall in FEV1 decreased more after treadmill exercise than after the step test. After step test and treadmill exercise no significant correlation was found between % fall in FEV1 and baseline lung function, or between % fall in FEV1 among groups defined by habitual physical activity.Although the 3-min step test yields a lower % fall in forced expiratory volume in one second (FEV1) and a lower value of the area above the FEV1 curve than treadmill testing, it is a quick, economical, reproducible and portable alternative procedure for identifying exercise-induced asthma in outpatients and epidemiological studies. Baseline lung function and habitual physical activity have no influence on the amount or duration of exercise-induced asthma.

“…In football players, the prevalence of EIB ranged from 9% to 50% 12–17. Kukafka et al14 found a 9% prevalence of EIB among non-asthmatic young football players. A prevalence of up to 50% was reported in subjects who frequently complain of exercise-induced respiratory symptoms 15…”

BACKGROUND AND OBJECTIVES:Studies on exercise-induced bronchoconstriction (EIB) in team sports are lacking. The aim of this study was to screen for EIB among amateur teenage football players in Tunisia and to compare EIB prevalence between regions.METHODS:One hundred ninety-six male football players (mean age [SD], 13.5 [0.5] yrs), practicing in three different cities of Tunisia (Tunis, Sousse and Sfax), underwent an outdoor free run of 7 minutes. Forced expiratory volume in one second (FEV1) was recorded prior to and at 0, 3, 5, 10, 15, 20 and 30 minutes after the run. Players were screened for EIB positivity defined as a greater than 10% decline in FEV1 from the resting value at any timepoint.RESULTS:FEV1 decreased more than 10% in 30% of the players. EIB positivity was more common in Sfax (15.8%) than in Tunis (7.7%) (P =.03). Air humidity during the study was higher in Tunis.CONCLUSION:EIB is prevalent among amateur teenage football players in Tunisia. The prevalence differs between regions and seems to be dependent on air humidity levels.
