Respiratory muscle strengths and its association with body composition and functional exercise capacity in non-obese young adults

Background. The assessment of cardiopulmonary problems, exercise capacity, and inspiratory and expiratory muscle strength all depend on body composition, which is a crucial factor in determining human health. Objectives. The present study aimed to examine the effect of body composition and functional exercise capacity on respiratory muscle strength in young healthy adults. Material and methods. In the prospective study, sixty individuals aged between 18-25 years of age who were non-obese were evaluated in terms of body composition by body mass index, respiratory muscle strength by mouth pressure threshold and functional exercise capacities by six minute walking test and sit to stand test. Also, sociodemographic characteristics such as age, gender, education level, height and weight of the participants were recorded. Results. The relationship between body density (BD) parameters and inspiratory muscle strength was found to be moderate (r = 0.394, p 0.05). Conclusions. Present study showed a significant correlation between body density and inspiratory and expiratory respiratory muscle strength. However, no correlation was found between body composition and functional exercise capacity and respiratory muscle strength. Body density increment will affect respiratory muscle strength negatively

Six-minute walk test in pulmonary arterial hypertension

Exercise intolerance is the main characteristic of pulmonary arterial hypertension (PAH). The six-minute walk test (6MWT) and cardiopulmonary exercise test are widely used in assessing exercise capacity of PAH patients. Six-minute walk distance (6MWD) has been specified as the main clinical outcome in PAH and has been used as the primary end-point in many studies conducted for new PAH treatments. Using 6MWD as the end-point in clinical studies has many advantages. 6MWT is an inexpensive, easily applicable, and repeatable standardized test that is well-tolerated by PAH patients. Moreover, it is a valid measure of symptomatic improvement. It is correlated with variables of maximal cardiopulmonary exercise test as a measure of submaximal exercise capacity and disease severity markers such as functional class and pulmonary hemodynamics. It is widely used in clinical practice together with other invasive and non-invasive disease markers in assessing disease progression and response to treatment. In addition, it has prognostic importance and is a good prognostic marker. On the other hand, there are limitations to the use of 6MWD as the primary end-point in PAH treatment. It has decreased sensitivity in individuals with less severe disease and high 6MWD at baseline and decreased adequacy in assessing the effects of treatment in patients who are still under PAH treatment. Despite the limitations, 6MWD plays a key role in the evaluation and management of PAH patients
