通所リハビリテーション施設を利用中で、要介護認定が要支援1または2の高齢者43名を対象に、TTMに基づいて運動習慣化群24名と非運動習慣化群19名に分類し、運動行動の習慣化に関わる心理社会的要因について分析した。その結果、1)社会的要因に関しては、要介護度のみに2群間で有意差が認められた。2)心理的要因に関しては、健康度自己評価は両群間で有意差がみられなかったが、意思決定バランスの自覚的促進要因および運動セルフエフィカシー尺度の得点は運動習慣化群で有意に高値を示していた。一方、非運動習慣化群では意思決定バランスの自覚的阻害要因で「怠惰性」のみが有意に高値を示していた。

This study aimed to investigate the influence of control of inspiratory-expiratory (I:E) ratio on coordination between locomotor and respiratory rhythms. Exercises of 10 healthy women were performed at the intensity corresponding to ventilatory threshold. Breathing rhythms were spontaneous breathing and two control breathings which I:E ratios were 1:1 and 1:2. The degree of coordination at I:E ratio of 1:1 was significantly higher than that of other breathing rhythms. Compared with spontaneous breathing, RPE was significantly lower at I:E ratio of 1:1 and significantly higher at I:E ratio of 1:2. V^^・E/V^^・O_2 at I:E ratio of 1:2 was significantly higher than that of I:E ratio of 1:1. The results suggest that control of breathing rhythm affect RPE, and control I:E ratio of 1:1 might be effective for coordination during walking at moderate intensity.

[Purpose] The purpose of this study was to examine the effect of variations in breathing control on swallowing. [Subjects] The subjects were 22 healthy adults. [Method] For four patterns of breathing and swallowing (BS), we recorded suprahyoid muscle electromyography, respiratory airflow, the time of larynx actions and made a visual analog scale assessment for ease of swallowing (VAS-ES) in spontaneous swallowing (SS). [Results] Larynx action time had no significant differences between SS and BS, and suprahyoid muscle activities in BS were significantly lower than those of SS. VAS-ES in BS was significantly lower than that of SS. In the four patterns of BS, VAS-ES in the exhale-swallow patterns tended to show high values. [Conclusion] These results suggest that the exhale-swallow-exhale pattern in BS makes swallowing easy and effective.

Purpose: To alleviate dyspnea, physical therapists often instruct patients with chronic lung disease to do diaphragmatic breathing and coordination between their breathing and exercise rhythms. However, the relationship between breathing patterns and exercise coordination remains unknown. This study aimed to investigate the influence of two breathing patterns on coordination between breathing and exercise rhythms.
Methods: Incremental exercise testing was performed with a ergometer in 10 healthy male subjects and ventilatory threshold (VT) determined. Exercise intensity was defined as according with two workloads corresponding to 60%VT and 100%VT, respectively. Subjects used two breathing patterns, spontaneous and diaphragmatic. Subjects cycled four different exercise protocols for 6 minutes (two intensities and two breathing patterns). During cycling, leg movements, respiratory parameters and thoracoabdominal perimeters were continuously recorded. Coordination was considered to be present when the phase interval between the leg movement cycle and inspiration (or expiration) displayed a constant value ± 0.10 seconds for at least four consecutive breaths.
Results: The degree of coordination (%COORD) wasn't significantly different between the two breathing patterns. When breathing and cycling rhythms were coordinated, oxygen uptake was significantly higher than when not coordinated at workloads of 60%VT with spontaneous breathing (p < 0.05). However, between group differences for all other exercise parameters were not significant. Nor was there significant coordination between %COORD and oxygen uptake, and %COORD and oxygen equivalent.
Conclusion: These results suggested that breathing control does not affect %COORD, and that coordination between breathing and cycling rhythms does not necessarily cause a reduction in oxygen uptake at workloads corresponding to 60-100%VT.
