![]() We interpret the lack of difference in post-training values of RER and VCO 2 between groups as an absence of inhibition in glycolysis and glycogenolysis during exercise with additional dead space.īreathing through additional dead space has been a widely used intervention strategy in varying areas of physiology. ![]() A 12-session training program resulted in significant increase in performance time in both groups (from 17”29 ± 1”31 to 18”47 ± 1”37 in Exp p=0.02 and from 17”20 ± 1”18 to 18”45 ± 1”44 in Con p = 0.02), but has not revealed a significant difference in RER and VCO 2 in both post-training tests, performed at rest and during submaximal workload. In all training sessions, pCO 2 was higher and blood pH was lower in the Exp group (p < 0.001) ensuring respiratory acidosis. Pre-test and two post-training incremental exercise tests were performed for the detection of gas exchange variables. Subjects in Exp group were breathing through additional respiratory dead space (1200ml), while subjects in Con group were breathing without additional dead space. A single training session consisted of continuous, constant-rate exercise on a cycle ergometer at 60% of VO 2max which was maintained for 30 minutes. The training consisted of 12 sessions, performed twice a week for 6 weeks. Two groups of young healthy males: Experimental (Exp, n = 15) and Control (Con, n = 15), participated in this study. The primary outcome measures were respiratory exchange ratio (RER) and carbon dioxide production (VCO 2). ![]() ![]() The purpose of the study was to investigate the effects of implementing additional respiratory dead space during cycloergometry-based aerobic training. ![]()
