Pendahuluan: Indonesia masih mengalami masalah gizi yaitu masih terdapatnya status gizi kurang bahkan gizi buruk. Nutrisi yang rendah atau buruk dapat mengurangi massa otot skeletal dan pernapasan, yang menyebabkan penurunan FVC dan FEV. FVC dan FEV merupakan parameter dari fungsi paru. Penelitian terdahulu menyebutkan bahwa olahraga dapat meningkatkan fungsi dari sistim pernapasan. Senam Sehat Anak Indonesia (SSAI) merupakan salah satu pilihan olahraga pada anak. Penelitian ini bertujuan menganalisis pengaruh SSAI terhadap FEV1 dan FVC pada anak underweight. Metoda: Penelitian ini menggunakan one group pre and posttest design. Populasi target adalah 24 anak underweight berusia 9-12 tahun di SDN Tembalang. Dilakukan pemeriksaan FEV1 dan FVC sebelum dan setelah pasien melakukan SSAI. Perbedaan sebelum dan sesudah perlakuan menggunakan uji t-berpasangan. Nilai p dianggap bermakna apabila nilai p<0,05. Hasil: Peningkatan FEV1 (0,66±0,25) liter, FVC (0,22±0,28) liter setelah SSAI berturut-turut p=0,23 dan p=0,71. Diskusi: Pada SSAI dilakukan gerakan-gerakan senam yang dapat meningkatkan elastisitas paru serta memperkuat otot-otot pernapasan sehingga meningkatkan volume udara yang dapat diambil saat bernapas. Peningkatan nilai FVC dapat disebabkan oleh peningkatan volume dan elastisitas paru-paru. FEV1, FEV bervariasi dan tergantung dari otot pernapasan. Pada penelitian ini walaupun tidak bermakna secara statistik namun dalam rerata nilai FEV1 dan FVC terdapat peningkatan setelah SSAI. Hal ini mungkin dikarenakan frekuensi senam yang digunakan adalah frekuensi yang paling minimal yaitu 2 kali per minggu. Simpulan: SSAI 2 kali per minggu selama 6 minggu sebagai salah satu pilihan olahraga pada anak underweight usia 9-12 tahun namun dalam penelitian ini tidak didapatkan peningkatan bermakna pada FEV1 dan FVC. Diperlukan penelitian lebih lanjut menggunakan frekuensi latihan yang lebih banyak dan durasi yang lebih panjang serta menggunakan kelompok kontrol.

Low or poor nutrition can reduce skeletal and respiratory muscle mass, which causes a decrease in FVC and FEV. FVC and FEV are parameters of lung function. Previous research suggests that exercise can improve the function of the respiratory system. Senam Sehat Anak Indonesia (SSAI) is one of the sports for children. This study aims to analyze the effect of SSAI on FEV1 and FVC in underweight children. Method: The design of this study was one group pre and post test design. The target population was underweight children at Tembalang Elementary School. FEV1 and FVC were examined before and after the patient underwent SSAI. Difference before and after treatment using paired t-test. The p value is considered significant if the p value <0.05. Results: There was no significant increase of FEV1 (0.66 ± 0.25) liters, FVC (0.22 ± 0.28) liters after SSAI  with  p= 0.23 and p = 0.71, respectively. Discussion: At SSAI, gymnastic movements are performed that can increase lung elasticity and strengthen breathing muscles, thereby increasing the volume of air that can be taken while breathing. Increased FVC is caused by an increase in lung volume and elasticity. FEV1, FEV varies and depends on the respiratory muscles. In weak expiratory muscles, a person's ability to expiration rapidly decrease and also the FEV1.FVC index. The mean of FEV1 and FVC values ??after SSAI increased but were not significant. In this study, although not statistically significant, the mean values ??of FEV1 and FVC were increased after SSAI. This may be due to the frequency of gymnastics used is the most minimal frequency of 2 times per week. Conclusion: SSAI twice per week for 6 weeks as one of the exercise choices in underweight children aged 9-12 years but in this study no significant increase in FEV1 and FVC was found. Further research is needed using more exercise frequency and longer duration and using a control group.Keywords: Underweight children; Forced Expired Volume in one second (FEV1); Forced Vital Capacity (FVC); Senam Sehat Anak Indonesia (SSAI)

Background: Obesity currently becomes one of the world's problems that can decrease a person’s quality of sleep. Pilates exercise was found to improve sleep quality in obese patients. Pilates exercise are safe to do because they don't involve jumping and running so they avoid trauma. Mat Pilates exercise is basic exercises that are done on the floor on a mat with simpler movements.Objective: To analyze sleep quality in obese young adults before doing Mat Pilates exercise and to compare changes in sleep quality for obese young adults before and after doing Mat Pilates exercise.Methods: This study used a quasi-experimental design applying one group pre-posttest. Samples were taken by purposive sampling with a total of 36 people who met the inclusion and exclusion criteria. The measurement of sleep quality used the Pittsburgh Sleep Quality Index (PSQI) questionnaire. Data analysis was tested for normality by using the Shapiro-Wilk test and the effect of Mat Pilates exercise on sleep quality in the treatment group using the Wilcoxon test. The difference is significant if p <0.05.Results: The average sleep quality for young adults before participating in the Mat Pilates exercise was 8.22 ± 1.87, while the average sleep quality for young adults after participating in the Mat Pilates exercise was 4.33 ± 0.77. The statistical test results showed that there was a significant difference (p = <0.001).Conclusion: There is an improvement in the mean value of sleep quality after doing Mat Pilates exercise.

ABSTRAK  Pendahuluan : Menurunnya kapasitas fisik lansia dapat menjadi faktor yang menyebabkan kurangnya partisipasi lansia untuk latihan dalam meningkatkan kebugaran kardiorespirasi. Dibandingkan dengan senam lansia ataupun Tai chi, senam Qigong memiliki gerakan yang sederhana, lambat, dan intensitas rendah sehingga akan mudah dipelajari dan meningkatkan partisipasi lansia dalam latihan. Meskipun latihan ini merupakan latihan dengan intensitas ringan-sedang, senam Qigong memiliki efek aerobik yang cukup baik untuk meningkatkan kebugaran kardiorespirasi.   Tujuan : Penelitian ini bertujuan mengetahui pengaruh senam Qigong terhadap kebugaran kardiorespirasi lansia.   Metode : Penelitian ini merupakan quasi experimental. Sampel berjumlah 21 orang lansia di Panti Pelayanan Sosial Lanjut Usia, Pucang Gading, Semarang yang terbagi menjadi 2 kelompok yaitu kelompok Qigong (n=11) dan kelompok kontrol (n=10). Kelompok Qigong mendapatkan intervensi senam Qigong dan kelompok kontrol mendapatkan intervensi senam lansia. Intervensi pada kedua kelompok dilakukan 3 kali seminggu selama 8 minggu. Konsumsi oksigen maksimal (VO2max) yang merupakan indikator kebugaran kardiorespirasi diukur menggunakan 6 minute walk test(6MWT).   Hasil : Pada akhir penelitian, rerata nilai VO2max adalah 12,39 ± 3,60 ml/kg/menit pada kelompok Qigong dan 13,03 ± 4,75 ml/kg/menit kelompok kontrol dengan tidak ada perbedaan signifikan diantara kedua kelompok. Perbaikan nilai VO2max sebelum dan sesudah intervensi didapatkan sebesar 2,23 ± 1,40 ml/kg/menit pada kelompok Qigong dan 2,69 ± 0,75 ml/kg/menit pada kelompok kontrol dengan tidak ada perbedaan signifikan diantara kedua kelompok.   Simpulan : Senam Qigong dan senam lansia memberikan dampak perbaikan serupa terhadap kebugaran kardiorespirasi.   Kata kunci : Latihan Qigong, Lansia, Kebugaran kardiorespirasi  

Introduction: Excessive fat accumulation in the obese child causes complex problems in the respiratory system. Respiratory system function can be improved by exercise. One exercise model that is suitable for children is Senam Sehat Anak Indonesia (SSAI). The quality of the respiratory function system is measured using Peak Expiratory Flow Rate (PEFR).Objective: to validate the PEFR’s differences in obese children before and after performing SSAI.Methods: This research using one group pre-posttest experimental design with total sample of 20 obese children using purposive sampling method. The research instrument uses weight scale, height scale, and peak flow meter. SSAI was given to all subjects twice a week for six weeks. Paired T Test statistical analysis was used to examine the PEFR’s differences before and after performing SSAI, considered significant if p<0.05.Results: The PEFR’s mean of all subjects before performing SSAI was 258.25 ± 39.51 L∕minute, while PEFR’s mean after performing SSAI twice a week for 6 weeks was 282.50 ± 43.03 L∕minute, (p=0,000).Conclusion: The PEFR’s mean of obese children was increase significantly after performing SSAI twice a week for 6 weeks
