“…An initial analysis of available data on healthy subjects [1,2,12,118,[181][182][183][184][185][186][187][188][189][190][191] clearly indicated that only five of these studies [2,181,[184][185][186] fulfill minimum requirements to be considered as candidates to be used in the clinical setting [85]. However, Blackie et ah [184] cover a lim ited age span (55-80 yrs), and Bruce et al [186] pro vide data obtained with treadmill in a population of physically fit people.…”

“…The ventilatory apparatus (lungs and chest wall) is centrally involved in these responses since it provides the functional and structural basis for external gas exchange. The general characteristics of the ventilatory response to progressive exercise are well known; several studies have provided reference values for judging the adequacy of the system functioning under these special circumstances [2][3][4][5].…”

“…Surprisingly, this relevant aspect of the ventilatory response has been overlooked in previous normative investigations [2][3][4][5]. For instance, the few studies that have given reference values provided them at maximum exercise [4], or described only VT at one or two submaximal intensities [17,18].…”

The pattern and timing of breathing during incremental exercise: a normative study. J.A. Neder, S. Dal Corso, C. Malaguti, S. Reis, M.B. De Fuccio, H. Schmidt, J.P. Fuld, L.E. Nery. #ERS Journals Ltd 2003. ABSTRACT: Clinical evaluation of the pattern and timing of breathing during submaximal exercise can be valuable for the identification of the mechanical ventilatory consequences of different disease processes and for assessing the efficacy of certain interventions.Sedentary individuals (60 male/60 female, aged 20-80 yrs) were randomly selected fromw8,000 subjects and submitted to ramp incremental cycle ergometry. Tidal volume (VT)/ resting inspiratory capacity, respiratory frequency, total respiratory time (Ttot), inspiratory time (TI), expiratory time (TE), duty cycle (TI/Ttot) and mean inspiratory flow (VT/TI) were analysed at selected submaximal ventilatory intensities.Senescence and female sex were associated with a more tachypnoeic breathing pattern during isoventilation. The decline in Ttot was proportional to the TI and TE reductions, i.e. TI/Ttot was remarkably constant across age strata, independent of sex. The pattern, but not timing, of breathing was also influenced by weight and height; a set of demographically and anthropometrically based prediction equations are therefore presented.These data provide a frame of reference for assessing the normality of some clinically useful indices of the pattern and timing of breathing during incremental cycle ergometry in sedentary males and females aged 20-80 yrs. Eur Respir J 2003; 21: 530-538.
