“…In most of the investigations on the entrainment of breathing, spontaneous limb movements were used (Bechbache and Dun 1977;Bramble and Carrier 1983;Hildebrandt and Daumann 1965;Hill et al 1988;Kohl et al 1981;Loring et al 1990;Mahler et al 1991). Raûler et al (1990), andWaurick (1973) investigated spontaneous as well as rhythmically paced movements.…”

“…Limb movements have been found to in¯uence breathing during walking (Bechbache and Dun 1977;Hill et al 1988;Loring et al 1990;Raûler and Kohl 1996), running (Bramble and Carrier 1983), cycling (Hildebrandt and Daumann 1965;Kohl et al 1981), rowing (Mahler et al 1991),``tapping'' (Wilke et al 1975) and single-step-tracking ®nger movements . Waurick (1973) even presented evidence for coordination between rhythmical eye and breathing movements.…”

1. The mechanical resistance of the human forearm has been measured during imposed sinusoidal flexion-extension movements of the elbow joint. 2. The force required to move the limb can be divided into components required to move the mass, and components required to overcome the resistance offered by elastic and frictional properties of the muscles and other soft tissues. 3. When during a vigorous flexing effort the limb was subjected to a small amplitude sinusoidal movement each extension was followed by a considerable reflex contraction of the flexor muscles. At low frequencies of movement this reflex provided an added resistance to extension, but at 8-12 Hz the delay in the reflex pathway was such that the reflex response to extension occurred after the extension phase of the movement was over and during the subsequent flexion movement. The reflex activity then assisted the movement whereas at other frequencies it impeded it. 4. The reflex response to movement increased as the subject exerted a greater flexing force. 5. Small movements generated a relatively larger reflex response than big ones. 6. Even with large amplitudes of movement when the reflex activity was relatively small, the limb resisted extension with a high level of stiffness; this was comparable with the short range stiffness of muscles in experimental animals. 7. The fact that at some frequencies the reflex response assisted the movement implies that with appropriate loading the limb could undergo a self-sustaining oscillation at those frequencies.

“…Insofern alles Sprechen eine Modifikation der Ausatmung (und damit auch der Einatmung) ist und die Atmung ihrerseits über die respiratorische Sinusarrhythmie (RSA) die Herzfrequenz (heart rate, HR) beeinflusst, ist die Erforschung des Zusammenhangs von Herzschlag und Atmung beim Sprechen für diese Therapiemethode von besonderem Interesse. Die Interaktion von Atmung und Herzrhythmik wurde unter anderem in der Chronobiologie und Chronomedizin differenziert erforscht und beispielsweise durch die umfangreichen Arbeiten von Hildebrandt und Mitarbeitern [6][7][8][9][10][11] [7,8]. Ferner wurde ein Normwert dieses Quotienten von 4 unter Ruhebedingungen an grösseren Personengruppen festgestellt [8].…”

“…Ferner wurde ein Normwert dieses Quotienten von 4 unter Ruhebedingungen an grösseren Personengruppen festgestellt [8]. Andere Arbeiten untersuchten das Frequenzverhältnis und die Phasenkoppelung von Atmung und HR bei Taktatmung, im Nachtschlaf [9,10,20,21] oder nach ergometrischem Stress. Dabei wurde eine Homogenisierung des Frequenzverhält-nisses gegen 4, aber eine geringere Phasenkoppelung des Inspirationsbeginns an eine definierte Phase der Herzaktion unter Arbeit gefunden [9].…”

Das Konzept von Ergotropie (Leistungsbereitschaft) und Trophotropie (Erholungs-und Regenerationsbereitschaft) als polare Auslenkungen der vegetativen Reaktionslage des Organismus findet sich häufig in der Literatur zur Chronobiologie und Chronomedizin [6,10,11].…”

Wirkungen der Therapeutischen Sprachgestaltung auf Herzfrequenz-Variabilität und Befinden

Effects of Speech Therapy with Poetry on Heart Rate Variability and Well-Being Background: Anthroposophical Therapeutic Speech uses poems and exercises which typically induce rhythmical breathing. Speaking influences respiration and thus directly heart rate variability (HRV), in particular via respiratory sinus arrhythmia which, together with the slower rhythms of HRV, may be regarded as an indicator of sympathovagal balance. In chronomedicine numerous frequency ratios between physiological rhythms, especially in trophotropic phases, have been established. Integer ratios occur frequently and seem to be associated with the optimization of physiological processes. In larger groups the average pulse respiration quotient is about 4:1. Question: Can systematic effects on HRV, and thus on autonomic balance, be established through special speech therapy? Subjects and Methods: In two trained therapists and 7 untrained subjects the influence of different speech exercises and texts on HRV was investigated. With untrained subjects a total of 105 one-hour sessions, divided into speech and control exercises, was performed. The overall well-being and quality of well-being were assessed with questionnaires. Control evaluations were made in the same setting. Results: As a simultaneous effect, during speech exercises and texts typical intra- and inter-individually reproducible patterns in heart rate variability were observed. Reciting poems with a hexameter metric generates 2 oscillations with a 2:1 frequency ratio in the HRV spectrum. As immediate effects there were a significant drop in heart rate after speech sessions as well as a strengthening of vagus-related HRV parameters, especially after hexameter exercises. In comparison to control sessions the subjects felt significantly better, too. The different metric and poetic character of the texts was reflected clearly in the results.
