Therefore, data obtained from 20 individuals were analyzed. For inter-rater Z-VAD-FMK manufacturer reliability and concurrent validity, 17 subjects were initially recruited, of whom five had abnormal pulmonary function tests. Therefore, 12 individuals had their data obtained and analyzed. Table 1 presents the demographic, anthropometric and spirometric data of the two subject groups evaluated. At rest, 1570 respiratory cycles were included in the analysis, with an average (SD) of 38 (8) on the first day and 40 (9) on the second day. During exercise, 2249 respiratory cycles were analyzed,

with an individual average of 55 (19) on the first day and 57 (19) on the second day. HR during exercise on the first day was 70 (8%) of the maximum HR (220 − age). On the second day, the mean HR displayed during exercise

was 69 (9%) of the maximum. Table 2 shows the results for intra-rater reliability obtained at rest and during exercise, respectively. There were no statistically significant differences between the first and second days of the study for any of the variables, except for Vcw/Ti at rest. ICC values were at or above 0.75 for most variables, except for Ti/Ttot at rest. The CVME presented at or below 10% for most variables, except for Vcw at rest. For inter-rater reliability, 1098 respiratory cycles were analyzed with an average of 47 (12) per subject on the first day and 45 (10) on the second day. During exercise, 2211 respiratory Entinostat manufacturer cycles were analyzed, with an average of 91 (22) on the first day and 93 (22) on the second day. The HR was 65 (9%) of the maximum during exercise when subjects were evaluated by examiner 1 and 64 (7%) of the maximum when they were evaluated by

examiner 2. Table 3 shows the results for inter-rater reliability at rest and during exercise, respectively. Statistically significant differences between examiners were observed for the variables Vrcp%, Vrca%, Veecw and Veicw at rest and for Vrca%, Veecw and Veicw during exercise. ICC values were above 0.75 for most of the variables except for Thymidine kinase Vrcp%, Vrca%, Vrc% and Vab% during exercise. CVME was equal to or below 10% for all variables. The main results of this study shows that OEP provided good intra-rater and inter-rater reliability for the evaluation of the chest wall volumes in healthy subjects at rest and during submaximal exercise. Regarding the intra-rater reliability, the ICC values observed were higher than 0.75 at rest and during exercise for most of the variables. According to Portney and Watkins (2008), reliability is considered good when the coefficients are above 0.75. Moreover, with the exception of the variable VCW, which showed the coefficient of variation greater than 11%, this ratio was below 10% for all other variables. Only the variable Vcw/Ti at rest showed a statistically significant difference between the two days of testing.
