Indonesia is thethirdlargestcigaretteusersafter Chinaand India,which reached 146.86 million inhabitants. Smoking behavior is engulfi  ng all circles, including children. Dangers of smoking are undoubtedly makes a person not a long life. When compared with non smokers, smokers aged on average 10 years shorter and spend millions of dollars. Inhaled cigarette smoke may accelerate the decline in lung physiology caused by changes in the structure and function of the airway or parenchyma (tissue) in the lung. The objective of this study was to determine differences in pulmonary function (Vital Capacity/VC, Forced Vital Capacity/FVC, and Forced Vital Capacity of the fi  rst second/FEV1) in male smokers and non smokers at the Medical Faculty of uhammadiyah University of Surakarta and determine the effect of smoking on pulmonary function. This study used analytical research design with cross sectional approach. The subject of this study was the active student and employee at the Medicine Faculty, Muhammadiyah University of Surakarta. Purposive sampling method was random sampling. The results were tested by statistical tests of independent t-test with SPSS 16.0.The sample size obtained was 40  people consisted of 20 (50%) sample of smokers and 20 (50%) sample of non-smokers. There was not difference VC between male smokers and nonsmokers with p = 0.390. There was difference FVC between male smokers and nonsmokers with p = 0.000. There was difference FEV1 between male smokers and nonsmokers with p = 0.025.This study showed the difference in FVC and FEV1 between male smokers and nonsmokers in the Medicine Faculty, Muhammadiyah University of Surakarta, but VC did not.

BackgroundThe forced expiratory flows (FEFs) towards the end of the expiration may be more sensitive in detecting peripheral airways obstruction compared to the forced expiratory volume in 1 s and forced vital capacity (FVC). However, they are highly variable. A partial solution is to adjust the FEFs for FVC (FEF/FVC). Here we provide reference equations for these adjusted FEFs at 25%, 50%, 75% and 25–75% of FVC, which are currently lacking.MethodsWe included pulmonary healthy, never-smoker adults; 14 472 subjects from Lifelines, a biobank for health research, and 338 subjects from the department's control cohorts (NORM and Fiddle). Reference equations were obtained by linear regression on 80% of the Lifelines dataset and validated on the remaining data. The best model was defined as the one with the highest adjusted R2-value. The difference in variability between adjusted and unadjusted FEFs was evaluated using the coefficient of variation.ResultsFor all adjusted FEFs, the best model contained age, height and weight. The adjustment improved the coefficient of variation of the FEF75 from 39% to 36% and from 43% to 40%, respectively, in males and females. The highest percentage of explained variance by the reference equation was obtained for FEF75/FVC, 32%–38% for males, and 41%–46% for females, depending on the validation set.ConclusionWe developed reference equations for FVC-adjusted FEF values. We demonstrated minimally yet significantly improved variability. Future studies in obstructive airway diseases should demonstrate whether it is worthwhile to use these (predicted) adjusted FEF values.

Abstract: Lung is a vital organ that has a function in the human body. Lung function as the human respiratory system. Respiratory literally means the movement of oxygen from the atmosphere and reach the O2 cell and release carbon dioxide CO2 is required in the normal functioning of cells in the body. Pool is one of the most powerful aerobic exercise because it involves all the muscles in order to prime the body and as a result provide better overall results compared with other sports. Respiratory capacity doubled during maximal exercise than at rest. The purpose of this research is to know the difference Forced Vital Capacity on the athletes and not athlete swimming pool in North Sulawesi. The study design was a cross sectional analytic survey (cross-sectional) or only done once in a given time. The research location is housed in the department of Prof.. Dr. R. D. Kandou Manado. The samples taken were 30 studies. The results showed that the value of p = 0.005 <α = 0.01, and concluded that there are very significant differences between the athlete and not the athlete swimming pool. Keywords: athlete pool, forced vital capacity,  not the athlete pool     Abstrak: Paru merupakan organ yang mempunyai fungsi vital dalam tubuh manusia. Paru berfungsi sebagai alat pernafasan manusia. Pernafasan secara harafiah berarti pergerakan oksigen O2 dari atmosfer menuju ke sel dan keluarnya karbondioksida (CO2) dari sel ke udara bebas. Pemakaian O2 dan pengeluaran CO2 di perlukan untuk menjalankan fungsi normal sel dalam tubuh. Renang  merupakan salah satu olahraga aerobik yang paling berdaya guna karena melibatkan seluruh otot utama tubuh dan sebagai hasilnya memberikan hasil keseluruhan yang lebih dibanding dengan olahraga-olahraga lain. Kapasitas pernafasan meningkat dua kali lipat pada saat berolahraga maksimal dibanding saat istirahat. Tujuan dari penelitian ini yaitu mengetahui perbedaan Forced Vital Capacity ( FVC ) pada atlit renang dan bukan atlit renang di Sulawesi utara. Penelitian ini merupakan penelitian analitik. Desain penelitian yaitu cross sectional atau studi potong lintang, dimana pengukuran hanya dilakukan satu kali pada satu saat pada suatu populasi di wilayah tersebut. Hasil penelitian ini menunjukkan bahwa nilai p = 0.005<α=0,01, dan dapat disimpulkan bahwa terdapat perbedaan yang sangat bermakna antara atlit renang dan bukan atlit renang. Kata Kunci: atlit perenang, bukan atlit perenang, kemampuan kapasitas vital paru.

Purpose The purpose of this preliminary study was to identify a vocal task that could be used as a clinical indicator of the vocal aptitude or vocal fitness required for vocally demanding occupations in a manner similar to that of the anaerobic power tests commonly used in exercise science. Performance outcomes for vocal tasks that require rapid acceleration and high force production may be useful as an indirect indicator of muscle fiber complement and bioenergetic fitness of the larynx, an organ that is difficult to study directly. Method Sixteen women (age range: 19–24 years, M age = 22 years) were consented for participation and completed the following performance measures: forced vital capacity, three adapted vocal function tasks, and the horizontal sprint test. Results Using a within-participant correlational analyses, results indicated a positive relationship between the rate of the last second of a laryngeal diadochokinesis task that was produced at a high fundamental frequency/high sound level and anaerobic power. Forced vital capacity was not correlated with any of the vocal function tasks. Conclusions These preliminary results indicate that aspects of the laryngeal diadochokinesis task produced at a high fundamental frequency and high sound level may be useful as an ecologically valid measure of vocal power ability. Quantification of vocal power ability may be useful as a vocal fitness assessment or as an outcome measure for voice rehabilitation and habilitation for patients with vocally demanding jobs.

Background Pulmonary complications after cardiac surgery are very common and lead to an increased incidence of post-operative morbidity and mortality. Several factors, either modifiable or non-modifiable, may contribute to the associated unfavorable consequences related to pulmonary function. This study was aimed to investigate the degree of alteration and factors influencing pulmonary function (forced expiratory volume in one second (FEV1) and forced vital capacity), on third, fifth, and seventh post-operative days following cardiac surgery. Methods This study was executed in 71 patients who underwent on-pump cardiac surgery. Pulmonary function was assessed before surgery and on the third, fifth, and seventh post-operative days. Data including surgical details, information about risk factors, and assessment of pulmonary function were obtained. Results The FEV1 and forced vital capacity were significantly impaired on post-operative days 3, 5, and 7 compared to pre-operative values. The reduction in FEV1 was 41%, 29%, and 16% and in forced vital capacity was 42%, 29%, and 19% consecutively on post-operative days 3, 5, and 7. Multivariate analysis was done to detect the factors influencing post-operative FEV1 and forced vital capacity. Discussion This study observed a significant impairment in FEV1 and forced vital capacity, which did not completely recover by the seventh post-operative day. Different factors affecting post-operative FEV1 and forced vital capacity were pre-operative FEV1, age ≥60, less body surface area, lower pre-operative chest expansion at the axillary level, and having more duration of cardiopulmonary bypass during surgery. Presence of these factors enhances the chance of developing post-operative pulmonary complications.
