The aim of the study was to determine the changes in blood hormone and respiratory parameters in recovery phases. 28 voluntary men participated in the study, with an average age of 19.75±1.61 years and playing active football during the league season. Wingate Anaerobic Power Test and Respiratory Function Test (RFT) were applied to the subjects who were randomly divided into two groups, active and passive group. Blood samples were collected from and RFT was applied to all subjects before and after the test. Cortisol hormone, Partial Oxygen Pressure (PO2), Partial Carbon Dioxide Pressure (PCO2), lactic acid (LA) values were obtanied with datas taken from blood samples. The forced vital capacity (FVC), forced expiratory volume (FEV1), and rate of 1. Second of forced expiratory volume to the forced vital capacity (FEV1 / FVC) were measured by the PFT test. SPSS 24.0 program was used for statistical evaluation of the data. As a result; both 5-minute active and passive recovery methods did not reduce the cortisol ratio, but continued to increase in minute increments. In terms of PO2, passive recovery was found to be a more effective method than active recovery. 5 minutes of active and passive recovery did not reduce LA level and did not affect each other significantly. FVC and FEV1 values were found to be higher in the active recovery group than in the passive recovery group at the onset of AT recovery. Active recovery was found to have positive effects on vital capacity FVC and FEV1.

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.

IntroductionIdiopathic pulmonary fibrosis (IPF) and systemic sclerosis-associated interstitial lung disease (SSc-ILD) are fibrotic ILDs with divergent disease populations. Little is known about health-related quality of life (HRQL) in SSc-ILD relative to IPF.MethodsWe used the Kings Brief Interstitial Lung Disease Questionnaire (K-BILD) to compare HRQL in a cross-sectional study of 57 patients with IPF and 29 patients with SSc-ILD. Analysis of covariance was used to adjust for age, gender and lung function.ResultsThe unadjusted mean K-BILD score was 63.1 (95% CI 57.1 to 69.1) among patients with SSc-ILD, as compared with 54.7 (51.8–57.5) among those with IPF (p=0.005). However, this difference in HRQL was attenuated after adjustment for age, gender and lung function. In a multivariable model, only forced vital capacity was associated with K-BILD scores. K-BILD scores were correlated with both forced vital capacity and with other relevant HRQL measures, regardless of ILD diagnosis.DiscussionPatients with SSc-ILD may have better ILD-specific quality of life than patients with IPF, but this difference appears to be driven primarily by better lung function. These results underscore the impact of lung function on HRQL in fibrotic ILD and the utility of K-BILD to assess HRQL in SSc-ILD.

Abstract Objective To investigate the potential contribution of accessory respiratory muscle atrophy to the decline of forced vital capacity (FVC) in patients with SSc-associated interstitial lung disease (ILD). Methods This single-centre, retrospective study enrolled 36 patients with SSc-ILD who underwent serial pulmonary function tests and chest high-resolution CT (HRCT) simultaneously at an interval of 1–3 years. The total extent of ILD and chest wall muscle area at the level of the ninth thoracic vertebra on CT images were evaluated by two independent evaluators blinded to the patient information. Changes in the FVC, ILD extent, and chest wall muscle area between the two measurements were assessed in terms of their correlations. Multiple regression analysis was conducted to identify the independent contributors to FVC decline. Results Interval changes in FVC and total ILD extent were variable among patients, whereas chest wall muscle area decreased significantly with time (P=0.0008). The FVC change was negatively correlated with the change in ILD extent (r=−0.48, P=0.003) and was positively correlated with the change in the chest wall muscle area (r = 0.53, P=0.001). Multivariate analysis revealed that changes in total ILD extent and chest wall muscle area were independent contributors to FVC decline. Conclusion In patients with SSc-ILD, FVC decline is attributable not only to the progression of ILD but also to the atrophy of accessory respiratory muscles. Our findings call attention to the interpretation of FVC changes in patients with SSc-ILD.
