ABSTRACT
The effects of bathing in a solution of artificial bath additive including inorganic salts and carbon dioxide (CO<SUB>2</SUB>-bathing: 41°C, 10 minutes; the concentration of carbon dioxide was 160-180 ppm, and that of inorganic salts was about 64 ppm) on the cardiovascular system, body flexibility, muscle stiffness and the subjective feeling of bathing were compared with those of no bathing and plain water bathing in the healthy subjects.<br> The deep body temperature and skin blood flow increased after bathing, and the increases after CO<SUB>2</SUB>-bathing were significantly greater than those after plain water bathing.<br>Body flexibility after CO<SUB>2</SUB>-bathing was similar to that of no bathing and plain water bathing.<br> Stiffness of the trapezius muscle was decreased at both 15 min and 30 min after CO<SUB>2</SUB>-bathing and plain water bathing, with no change in no bathing.

ABSTRACT
The effects of bathing in a solution of artificial bath additive including inorganic salts and carbon dioxide (CO2-bathing: 41°C, 10 minutes; the concentration of carbon dioxide was 160-180 ppm, and that of inorganic salts was about 64 ppm) on the cardiovascular system, body flexibility, muscle stiffness and the subjective feeling of bathing were compared with those of no bathing and plain water bathing in the healthy subjects. The deep body temperature and skin blood flow increased after bathing, and the increases after CO2-bathing were significantly greater than those after plain water bathing. Body flexibility after CO2-bathing was similar to that of no bathing and plain water bathing. Stiffness of the trapezius muscle was decreased at both 15 min and 30 min after CO2-bathing and plain water bathing, with no change in no bathing. The changes at 15 min after CO2-bathing and plain water bathing were statistically significant. Stiffness in the latissimus dorsi muscle decreased at both 15 min and 30 min after CO2-bathing and plain water bathing, with no change in no bathing. However, only these changes at 15 min and 30 min after CO2-bathing were statistically significant. A large decrease in the stiffness of the trapezius muscle by its isometric contraction was observed during both CO2-bathing and plain water bathing, and the decrease after CO2-bathing was greater than that after plain water bathing. These changes did not reach statistical significance. Improvements in subjective feeling of bathing were observed after both plain water bathing and CO2-bathing. Improvements after CO2-bathing in stiffness of muscle, ease of movements and mental relaxation were statistically greater than those after plain water bathing. Compared with plain water bathing, CO2-bathing showed additional effects on muscle stiffness and subjective feeling of bathing. Further research is needed to confirm the effectiveness of the CO2-bathing alone and combined with isometric movements on muscle stiffness.
ABSTRACT
<b>Objective</b>: Exercise baths are generally considered to be one of the most appropriate and advantageous rehabilitative therapies, yet their effects have not been comprehensively investigated. The aim of this study is to assess the efficacy of exercise baths on quality of life (QOL).<br><b>Methods</b>: The 49 subjects consisted of 20 patients with brain disease, 21 patients with orthopaedic disease, and 8 patients with other diseases (i.e., 7 life-style related diseases and one heat burn). In the present study, all patients were first treated by conventional rehabilitation comprising physical therapy and occupational therapy for 4.2±1.4 weeks. Exercise baths were then added to the rehabilitation program for a further 4.4±1.2 weeks. The subjects were immersed in water at 38°C for 30-60min, twice a week. QOL was evaluated by alterations in the MOS Short-Form 36-item Health Survey (SF-36). We defined the period from admission to exercise bath start as Treatment I, and the period from exercise bath start to discharge (exercise bath finish) as Treatment II. On admission, before and after exercise bath, QOL was evaluated using the SF-36 scores.<br><b>Results</b>: We found that the increase of all eight subscales of the SF-36 was smaller in Treatment I period than in Treatment II period. Increases in SF-36 scores were observed in all patients, in all eight domains. Specifically, after exercise baths, increased scores of Physical functioning (PF), Role physical (RP), General health (GH), Vitality (VT), Role emotional (RE) and Mental health (MH) subscales of the SF-36 were observed in the patients with brain disease. Further, after exercise baths, increased scores of PF, RP, Bodily pain (BP), GH, VT, RE and MH subscales of the SF-36 were observed in the patients with orthopedic disease.<br><b>Conclusions</b>: It was concluded that exercise baths are an effective non-pharmacological treatment that might facilitate rehabilitation programs.
