“…On the other hand, significance values further suggest that expiratory muscle strength may be more correlated with functional capacity than inspiratory muscle strength. Our results are in agreement with previous studies reporting the potential relationship between inspiratory muscle strength and functional capacity (Demir et al, 2018;Zeren et al, 2016). Furthermore, it has been reported that respiratory muscle weakness is associated with reduced functional capacity in hemodialysis patients (Figueiredo et al, 2017).…”

Chest wall expansion determines lung volume and functional capacity. Factors determining chest wall expansion include respiratory muscle strength. Accordingly, there may be association among respiratory muscle strength, chest wall expansion, and functional capacity. Thusly, this cross-sectional study identified the relationship between respiratory muscle strength, chest wall expansion, and functional capacity. Seventy-six healthy male and female participants aged between 20 to 59 years exhibiting a body mass index of 18.5 to 22.9 kg/m 2 were enrolled. Inspiratory and expiratory muscle strength were evaluated via maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP), respectively. Chest wall expansion was measured through thoracic circumferences at three different levels; upper, middle, and lower levels with diaphragmatic movement also measured utilizing the circumference of the lower edge of the 10th rib. Functional capacity was evaluated through distance obtained from a 6-min walk test. Results showed that both MIP and MEP were significantly correlated with chest wall expansion at the middle (P= 0.005 and P= 0.006) and lower (P= 0.012 and P= 0.020) thoracic levels as well as diaphragmatic movement (both P< 0.001). Moreover, both MIP and MEP were significantly related amid the 6-min walk distance (P= 0.025 and P< 0.001). In conclusion, respiratory muscle strength is positively associated with chest wall expansion, diaphragmatic movement, and functional capacity in healthy participants.

“…In addition, IMS values were negatively correlated with anxiety and depression in preoperative heart surgery. Similarly, Demir et al 35 reported that IMS and FC are negatively associated with quality of life (e.g., emotional dimension) among patients with atrial fibrillation. Therefore, a poor IMS and low FC are associated with poor psychological health conditions, and also cardiorespiratory fitness is one of the predictors of mortality in patients with OHS.…”

“…Anxiety and depression might affect the severity of a patient's symptoms, leading to a poorer quality of life for the patients. 35,36 One explanation might be that these patients required cardiac surgery because they either had intractable angina from CAD or extreme dyspnea from valvular disease. It is possible that the more severe their disease, the worse their preoperative symptoms were, and the less they were able to perform daily activities.…”

Background: Poor psychological health and cardiorespiratory fitness prior to open heart surgery (OHS) might be predictors of postoperative pulmonary complications that lead to morbidity and mortality. Assessment of physical and psychological conditions should be considered for patients receiving OHS, to possibly prevent these complications. This study investigates how inspiratory muscle strength (IMS) and functional capacity (FC) relate to the psychological health of preoperative cardiac surgery patients. Method: A cross-sectional study was designed before OHS; the 6-minute walk test and IMS were performed on patients who were admitted for OHS. All participants were requested to complete Hospital Anxiety and Depression Scale. Pearson correlation and hierarchal regression analysis were performed to determine the relationships between IMS and FC and psychological conditions (anxiety and depression). Results: Overall, 36 males and 28 females aged 56.89±10.23 years were recruited. Significant relationships were observed between IMS and anxiety and depression symptoms (r = –0.33 and r = –0.27, respectively). Anxiety was negatively related to FC ( r = –0.25). These relationships remained significant after adjustment for age, sex, and body mass index (BMI) (∆ R2 = 0.11 and ∆ R2 = 0.09). In addition, anxiety was also related to FC after controlling for age, sex, and BMI (∆ R2 = 0.09). Conclusion: Among patients undergoing OHS, those with a higher level of depression or anxiety had a lower cardiorespiratory fitness than those with a low level of depression or anxiety.

“…Because of recent improvements in science and technology, as well as more successful cardiovascular disease diagnosis, the number of people living with congenital heart disorders (CHD) and reaching adulthood is increasing [ 1 , 2 ]. Congenital heart disease (CHD) patients have a variety of physiologic issues, including decreased aerobic capacity, exertional dyspnea, cardiovascular and peripheral muscle deconditioning, and muscle atrophy and weakness [ 3 , 4 , 5 ]. There is earlier evidence that exercise capacity is not regulated by cardiac variables in isolation, but depends on a complex interplay between cardiopulmonary and muscular components in CHD [ 6 , 7 ].…”

This study will evaluate cardiorespiratory and peripheral muscle function and their relationship with subjective dyspnea threshold after the surgical correction of congenital heart disease in children. Thirteen children with surgically repaired congenital heart disease were recruited. Each participant performed an incremental exercise test on a cycle ergometer until exhaustion. Gas exchanges were continuously sampled to measure the maximal aerobic parameters and ventilatory thresholds. The functional capacity of the subjects was assessed with a 6 min walk test. At the end of the exercise test, isokinetic Cybex Norm was used to evaluate the strength and endurance of the knee extensor muscle in the leg. Dyspnea was subjectively scored with a visual analog scale during the last 15 s of each exercise step. Oxygen consumption measured at the dyspnea score/VO2 relationship located at the dyspnea threshold, at which dyspnea suddenly increased. Results: The maximal and submaximal values of the parameters describing the exercise and the peripheral muscular performances were: VO2 Peak: 33.8 ± 8.9 mL·min−1·kg−1; HR: 174 ± 9 b·min−1; VEmax: 65.68 ± 15.9 L·min−1; P max: 117 ± 27 W; maximal voluntary isometric force MVIF: 120.8 ± 41.9 N/m; and time to exhaustion Tlim: 53 ± 21 s. Oxygen consumption measured at the dyspnea threshold was related to VO2 Peak (R2 = 0.74; p < 0.01), Tlim (R2 = 0.78; p < 0.01), and the distance achieved during the 6MWT (R2 = 0.57; p < 0.05). Compared to the theoretical maximal values for the power output, VO2, and HR, the surgical correction did not repair the exercise performance. After the surgical correction of congenital heart disease, exercise performance was impeded by alterations of the cardiorespiratory function and peripheral local factors. A subjective evaluation of the dyspnea threshold is a reliable criterion that allows the prediction of exercise capacity in subjects suffering from congenital heart disease.
