Data are mean ± SD
*p < 0.05; **p < 0.01, land vs. warm water immersion.
There were no significant differences between the sessions.
A: Baseline, B: After 8 weeks of control period without changes in daily lifestyle,
C: After 8 weeks of hydrotherapy twice weekly.
Bpm, beat per minute; LV, left ventricular; LVEDV, left ventricular enddiastolic volume; PCWP, pulmonary capillary wedge pressure; RU, resistant unit; RV, right ventricle; SV, stroke volume; SVR, systemic vascular resistance; TVTI, tissue velocity time integral; WWI; warm water immersion.
