Table 2. Resting respiratory exchange ratio (RER), oxygen uptake (VO), carbon dioxide production (VCO) during breathing for three minutes in two conditions: without tube and through a tube (1200ml). During breathing through additional dead space, gas sampling line was placed at the terminal end of the tube. Tests were conducted before training session number 6, on 8 randomly selected subjects. Data are presented as mean (± one SD)
