Background Futsal is a high risk sport, especially in youth level. But none has studied the application of FIFA 11+, the football injury prevention program among youth futsal players in Indonesia. Objective To determine the effectiveness of FIFA 11+ in improving physical fitness components affecting injury risks among youth futsal players. Design This experimental study was recruiting two groups of youth futsal players by doing purposive/judgmental random sampling to the senior high school futsal teams in Yogyakarta, Indonesia. Setting High school futsal league. Participants The subjects were high school students participating in the school futsal team. From the total of 28 subjects (15 subjects in the experiment group and 13 in control group), 8 subjects were dropping out, leaving 9 subjects in the experiment group and 11 in the control group for the final analysis. Risk factor assessment The experiment (EXP) group underwent FIFA 11+ training twice per week for four weeks while the control (CON) group underwent routine futsal training. Both groups performed physical fitness tests before and after the intervention. Changes in performance (pre- vs. post-intervention) for each group were analyzed using dependent t-test (P<.05). Change in performance of each group were compared using independent t-test (P<.05). Main outcome measurements Core strength (evaluated using plank test), leg power (vertical jump test) and agility (Illinois agility test). Results: The core strength (P=.007) and agility (P=.01) of the EXP group increased significantly, while no change were observed in the CON group. The increase of agility in EXP group was found to be significantly different compared to the one in CON group (P=.039). Conclusions: FIFA 11+ can improve certain physical fitness components that contribute in preventing injury. Thus it is recommended to add FIFA 11+ to the routine futsal training as an injury prevention program Table 1 Pre-post intervention result. .

Tujuan Aktivitas fisik rendah menyebabkan kebugaran jasmani kurang, yang berdampak pada produktivitas. Penelitian ini bertujuan untuk mengetahui pengaruh aktivitas fisik terkait pekerjaan yang rendah dan faktor risiko lainnya terhadap kebugaran jasmani pekerja.

During the coronavirus desease 2019 (COVID-19) pandemic, athletes must be able to adapt to new habits, such as: social restriction, change of competition schedule, and sending back home. This situation has led to an 18.2% increase in sleep disturbances. This study aimed to look at the sleep duration of adolescent athletes during the COVID-19 pandemic and its impact on athlete’s health conditions. A total of 126 adolescent athletes from 15 sports were recruited in this cross-sectional study. Adequate sleep duration was assessed according to the American Academy of Sleep Medicine criteria. Data on health conditions, medical history, injury history, were taken using a questionnaire. Behavioral assessment was assessed through the strengths and difficulties questionnaire. About 80.2% of adolescent athletes had insufficient sleep, and there was a significant relationship between sleep duration and disease incidence with a relative risk (RR) of 3.31 (1.32-8.28) 95% convidence interval (CI). There was no significant relationship between adequate sleep duration and health conditions (p&gt;0.05). Things that may be the cause of sleep disturbances; use of electronic devices (37.6%), environmental conditions (53.4%), and worry (9%). In the end, this indicates adolescent athletes face difficulties in achieving adequate sleep duration during this pandemic and a continuous surveillance system is needed to monitor athletes outside the dormitory.

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)
