Data are shown as mean ± SD of all 26 subjects included in the study. Changes in peak pressure (panel A), maximum relaxation rate (MRR—panel B), half-time of relaxation curve (½RT—panel C), and time constant of the relaxation curve (τ—panel D) obtained from sniff curves of all subjects during recovery from fatigue protocol were compared with pre-fatigue values (line at zero). cmH2O: centimeters of water; ms: milliseconds. *p < 0.05; **p < 0.01; and ***p < 0.0001.
