Prevalence of Exercise-Induced Bronchospasm by laboratory exercise challenge among Ragunan Sport School athletes

Abstract

AbstrakExercise-induced bronchospasm (EIB) sering dijumpai pada atlet remaja. Penelitian untuk mengetahui prevalensi EIB pada atlet remaja di Indonesia belum pernah dilakukan. Penelitian ini dilakukan untuk mengetahui prevalensi EIB pada atlet Sekolah Olahraga Ragunan dengan menggunakan tes latihan di laboratorium. Setiap atlet melakukan latihan sepeda statis (Monark, Swedia) hingga mencapai intensitas latihan minimal pada 90% laju jantung maksimal. "Force expiratory ventilation" (FEV) diperiksa dengan menggunakan spirometri (Minato AS-PAL, Jepang) pada menit ke 0, 5, 10 dan 20 pasca latihan. Diagnosis EIB ditentukan bila terdapat penurunan FEV 1 10% atau lebih dibanding nilai basal. Suhu dan kelembaban ruangan selama penelitian berkisar 28°C-31°C dan 74%-82%. AbstractExercise-induced bronchospasm (EIB) is a common condition among adolescent athletes. There has been no study examining the prevalence of EIB among adolescent athletes in Indonesia. This study aimed to get the prevalence of EIB among Ragunan Sport School athletes by laboratory exercise challenge. Subjects performed static cycle ergometer exercise (Monark, Sweden) to reach minimal workload of 90% maximal heart rate. Force expiratory ventilation (FEV 1 ) was examined by spirometry (Minato AS-PAL, Japan) at minute 0, 5, 10 and 20 post exercise. The EIB was defined as a decline of FEV 1 as much as 10% or more from baseline value. Room temperature and humidity were 28°C-31°C and 74%-82% respectively. There were 168 athletes from 12 sport types who participated in this study. Among them, 23 athletes (13.7%) were EIB positive. The highest percentage of EIB was in taekwondo (54.5%). Sixteen athletes with EIB (70%) were from less asthmogenic sports. Athletes with EIB consisted of 17 (17.5%) females and 6 (8.4%) males. In conclusion, the prevalence of EIB among adolescent athletes was moderately high, and was more prevalent in female. More over, laboratory exercise challenge could elicit EIB in less asthmogenic sport. (Med J Indones 2008; 17: 33-6)

Global prevalence of exercise‐induced bronchoconstriction in childhood: A meta‐analysis

“…Ten studies involving 1773 participants (223 cases of EIB) investigated the prevalence of EIB in child and adolescent athletes. Five studies recruited male soccer players, and other five studies included athletes of different modalities. The pooled prevalence of EIB was 15% (95% CI: 9‐21%) (Figure ).…”

“…Thirty‐three studies investigated the prevalence of EIB in general population of children and adolescents. Ten studies reported the prevalence of EIB in child and adolescent athletes, and 23 studies in children and adolescents with asthma.…”

Exercise-Induced Bronchoconstriction Among Adolescent Athletes With Asthma: A Systematic Review

“…A total of ten studies with 3129 adolescent athletes were included, and their ages ranged from seven to 20 years. Three studies were conducted in the USA [ 15 - 17 ], one in Greece [ 18 ], one in Tunisia [ 19 ], one in Poland [ 20 ], one in Japan [ 21 ], one in Germany [ 22 ], one in Iran [ 23 ], and one in Brazil [ 24 ]. Five studies were cross-sectional studies [ 15 , 16 , 19 , 21 , 23 ], three were cohort studies [ 18 , 22 , 24 ], one was a prospective study [ 20 ], and one was an observational study [ 17 ].…”
