Table 1.
Anthropometric data of yoga and control groups.
Table 2.
Lung function, respiratory muscle strength and breath-hold duration.
Fig 1.
Ventilation and pattern of breathing at rest (mean ± SD) in yoga (YOGA, empty circles, empty rhombus for less fit subjects, see 3.6) and control (CON, full circles) groups.
V̇E, ventilation; VT, tidal volume; fR, respiratory frequency; PETCO2, end-tidal CO2 partial pressure. Significances are indicated for differences between YOGA and CON. * p < 0.05.
Fig 2.
Respiratory data (mean ± SD) of yoga (Y) and control (C) groups at baseline (spontaneous breathing at rest) and during hypercapnia (achieving 55–61 mmHg end-tidal CO2 partial pressures [PETCO2]).
V̇E, ventilation; VT, tidal volume; fR, respiratory frequency. Bottom right: Slope of the average regression lines (y) between V̇E and PETCO2. Significances are indicated for differences between Y and C and changes from baseline to hypercapnia. * p < 0.05, ** p < 0.01.
Fig 3.
Respiratory data (mean ± SD) for the reduced dataset of yoga (Y, n = 6, see 3.6) and control (C) groups at baseline and during passive exercise.
V̇E, ventilation; VT, tidal volume; fR, respiratory frequency; PETCO2, end-tidal CO2 partial pressure. Significances are indicated for differences between Y and C and changes from baseline to passive exercise. * p < 0.05, ** p < 0.01.
Fig 4.
Time course of 15s data (mean ± SD) of the reduced data set (YOGA, n = 6) during the first 8 min of ICT and during the first 8 min of CET and at exhaustion of the yoga (empty circles) and control (full circles) groups.
V̇E, ventilation; VT, tidal volume; fR, respiratory frequency; PETCO2, end-tidal CO2 partial pressure; HR, heart rate.
