VO2 max can be measured with two protocols, namely direct and indirect. Direct protocols are known to be valid, but more difficult and expensive. The indirect protocol is often asked of its validity, but it is practical and cheapest to use in the field. One of the indirect protocols that can be used in children is 20-meter Multi-Stage Running (20-MST). This study aimed to determine the correlation between the 20-MST with Cardiopulmonary Exercise Testing (CPET) in boys. This research used descriptive analytic study design. The subjects were 38 boys aged from 11 to 12 of extracurricular sports club members. The research variables are VO2 max results with 2 methods of measurement which are 20-MST and CPET. The statistical data were analyzed with Pearson correlation. The result of VO2 max (ml.kg-1-1.min) measurement by the method of 20-MST (28.6 ± 7.962) and result by the method of CPET (40.683 ± 10.7 31) and the correlation value between 20-MST and CPET with R=0.674. We concluded that there is a strong correlation between 20-MST test and CPET test for predicting VO2 max among boys.

Abstract Background Compared with the cardiac exercise stress test, more commonly used to assess the presence of ischemia, the cardiopulmonary exercise test has the advantage of providing expired gas analysis. According to current guidelines, cardiopulmonary exercise testing should be considered to stratify the risk of adverse events and to provide measures of survival improvement in heart failure populations. However, cardiac exercise stress test is more readily available and widespread than cardiopulmonary exercise testing. We aimed to compare prognostic information given by estimated pVO2 – which can be obtained from cardiac exercise stress test – and real measured pVO2 – which requires cardiopulmonary exercise test – in a heart failure population. Methods We conducted a retrospective analysis of 214 patients with HF underwent cardiac exercise stress test and accessed their 5 year survival. Non-urgent transplanted (UNOS Status 2) patients were censored alive on the date of the transplant. Duringthe cardiopulmonary exercise test, cardiac exercise stress test data simultaneously collected. Based on protocol stage achieved, estimated METs were used to calculate estimated pVO2 (pVO2 = estimated METs x 3.5). Estimated and real pVO2 were correlated using Pearson correlation and the age-adjusted prognostic power of each was determined using Cox proportional hazardsanalysis. Results 164 patients were male (77%) and the mean age of the population was 56±10 years. 78 (36%) patients had an ischemic etiology. Within 5 years from testing, 46 patients died (21.5%) and 55 patients (26%) were transplanted. Naughton modified (n=165) was the most commonly used protocol, followed by Naughton (n=39) and Bruce (n=10). Estimated pVO2 and measured pVO2 correlated significantly (R=0.66, p<0.01) (Figure 1). Both estimated (HR=0.91, 95% CI 0.86–0.95, p<0.01) and measured pVO2 (HR=0.86, 95% CI 0.80–0.91, p<0.01) strongly predicted prognosis in this population. Conclusions Estimated pVO2 correlated with measured pVO2 and strongly predicted prognosis in this heart failure population. Because it can be obtained from conventional cardiac exercise testing, it may become an alternative prognostic tool to cardiopulmonary testing.

Dynamic Lung Hyperinflation

In chronic obstructive pulmonary disease (COPD), exertional dyspnea, which increases with the disease’s progression, reduces exercise tolerance and limits physical activity, leading to a worsening prognosis. It is necessary to understand the diverse mechanisms of dyspnea and take appropriate measures to reduce exertional dyspnea, as COPD is a systemic disease with various comorbidities. A treatment focusing on the motor pathophysiology related to dyspnea may lead to improvements such as reducing dynamic lung hyperinflation, respiratory and metabolic acidosis, and eventually exertional dyspnea. However, without cardiopulmonary exercise testing (CPET), it may be difficult to understand the pathophysiological conditions during exercise. CPET facilitates understanding of the gas exchange and transport associated with respiration-circulation and even crosstalk with muscles, which is sometimes challenging, and provides information on COPD treatment strategies. For respiratory medicine department staff, CPET can play a significant role when treating patients with diseases that cause exertional dyspnea. This article outlines the advantages of using CPET to evaluate exertional dyspnea in patients with COPD.

Abstract Chronic kidney disease (CKD), especially end-stage kidney disease (ESKD), is associated with increased risk for cardiovascular events and all-cause mortality. Exercise intolerance as well as reduced cardiovascular reserve are extremely common in patients with CKD. Cardiopulmonary exercise testing (CPET) is a non-invasive, dynamic technique that provides an integrative evaluation of cardiovascular, pulmonary, neuropsychological and metabolic function during maximal or submaximal exercise, allowing the evaluation of functional reserves of these systems. This assessment is based on the principle that system failure typically occurs when the system is under stress and, thus, CPET is currently considered to be the gold-standard for identifying exercise limitation and differentiating its causes. It has been widely used in several medical fields for risk stratification, clinical evaluation and other applications but its use in everyday practice for CKD patients is scarce. This article describes the basic principles and methodology of CPET and provides an overview of important studies that utilized CPET in patients with ESKD, in an effort to increase awareness of CPET capabilities among practicing nephrologists.
