“…The percentage of diminution of FEV 1 is very significant in group 3. The conveyor belt test has led to bronchial contraction by hyperventilation (Lumme et al, 2003), which resulted in a reduction in maximum expiratory volume per second and an increase in FEV 1 diminution to 10%. When the subjects are treated with the aqueous extract of Sterculia setigera at 125 g dose, the percentage of diminution in FEV 1 falls to 95.17%.…”

A b s t r a c t A r t i c l e I n f oSterculia setigera Delile (Sterculiaceae) is a plant commonly used in African traditional medicine and pharmacopoeia to treat many pathology including cough and asthma. The present study aim to evaluate the effect of aqueous extract of Sterculia setigera leaves on exercise-induced bronchospasm in athletes. Subjects underwent a treadmill bronchial test and a spirometry test before and after treatment with this aqueous extract. The comparison of subjects ventilatory parameters is carried out and certain inflammatory proteins tested. The results showed that aqueous extract of Sterculia setigera leaves improved significantly the ventilation parameters of subjects and declined the percentage in forced expiratory volume per second (FEV 1 ). Subjects Blood concentration in C-reactive protein (CPR) and erythrocyte sedimentation rate were also be reduced. These results justify the traditional use of Sterculia setigera in the treatment of asthma and cough in Benin. This extract can therefore be used in the treatment of asthma or exercise-induced bronchospasm (EIB) in elite athletes.

“…Sputum eosinophilia (w2% of the differential cell count) affected one-fifth of highly trained swimmers [17,18] and one-tenth of ice hockey players [8]. Those swimmers with exercise-induced bronchial symptoms had significantly higher sputum eosinophil cell counts (mean 7.6%) than the symptom-free swimmers (mean 0.7%) [17].…”

Asthma has a higher prevalence in athletes compared with the general population. In summer sport events, the prevalence ranges 3.7-22.8%, as reviewed by Helenius and Haahtela [1]. In winter sport events, the occurrence is even higher, ranging 2.8-54.8% (table 1) [2][3][4][5][6][7][8]. A total of 17% of 253 Finnish elite summer sport athletes used asthma medication, most commonly inhaled b 2 -agonists [1]. Also, 17% of the USA Winter Olympic Team (Nagano, Japan) were current users of asthma medication [5], while the figure was twice as high (36%) amongst Swedish cross-country skiers [2]. In a Swedish study in upper secondary schools for young skiers, 15% had phsysician-diagnosed asthma and 18% were treated with anti-asthma drugs compared with 6% and 7%, respectively, amongst the controls [9]. Occurrence of bronchial hyperresponsivenessBronchial hyperresponsiveness (BHR) is correlated with clinical asthma symptoms, but the relationship is not straight forward. Larsson et al. [2] observed that 23 out of 42 (54.8%) cross-country skiers had BHR and asthma symptoms. Two skiers had BHR without symptoms and 17 had symptoms, but no BHR. Leuppi et al. [7] found that 35% of Swiss ice hockey players had BHR, but clinical asthma was diagnosed in 19% and exercise-induced bronchospasm (EIB) in 11% of them. The respective figures for BHR, clinical asthma and EIB were lower in floor ball players: 21%, 4.2% and 4.2%.Sue-Chu et al.[3] reported that in cross-country skiers the figures for BHR and clinical asthma were closer to each other: 14% and 12% in Norway, and 43% and 42% in Sweden, respectively. Karjalainen et al.[10] studied 40 young elite skiers and 12 healthy control subjects. BHR to methacholine was found in 30 (75%) of the skiers, and one-third of them had symptoms suggestive of asthma.BHR is also prevalent in swimmers. Zwick et al.[11] found competitive swimmers to have BHR significantly more often than control subjects (78% versus 36%). In another study, BHR was detected in 60% of swimmers and in 12% of nonswimming athletes [12]. The prevalence of BHR was higher in swimmers (36%) than in speed and power athletes (18%) and in long-distance runners (9%) [13]. A "healthy runner effect" certainly takes place, especially in long-distance runners. BHR was significantly associated with atopy.Conclusions of the associations are problematic in cross-sectional studies because dynamic variables fluctuate over time depending on various factors. Heir et al. [14] observed that acute respiratory tract infections were associated with a transient increase
