    Notes: Abstract Efferent motor signals to skeletal muscles concern not only the space/time pattern of motion, but also the setting of muscular performance and through this the control of the current metabolic rate. For an optimal adjustment of metabolic rate during heavy exercise — e.g. in athletic competitions — a feedback control system must exist, including a programmer that takes into consideration a finishing point (teleoanticipation). The presented experiments, using Borg's scale, indicate the existence and functioning of a system for optimal adjustment of performance during heavy exercise and the relevance of teleoanticipatory effects. Thus motor learning includes not only somatosensory control, but also metabolic control. With regard to migratory birds, such metabolic control would have to operate in the individual as well as in the migrating flock as a whole.

    Description / Table of Contents: Zusammenfassung Ein neu entwickeltes System zur $$p_{a_{CO_2 } } $$ -geregelten Ventilation wird vorgestellt. Mit Hilfe einerp CO 2-Katheterelektrode (Fa. General Electric) wird kontinuierlich der arterielle Kohlensäurepartialdruck gemessen. Die in einenp CO2-Regler einlaufenden Potentiale werden mit einem variabel einstellbaren $$p_{a_{CO_2 } } $$ -Sollwert verglichen. Die Spannungs-differenz zwischen $$p_{a_{CO_2 } } $$ -Soll- und Istwert modifiziert die Ventilationsvorgabe eines mit Servo-Ventilen arbeitenden Beatmungsgerätes (Servo-Ventilator 900, Fa. Dräger) so lange nach, bis sich bei minimaler Regelabweichung $$p_{a_{CO_2 } } $$ -Soll- und Istwert entsprechen. Die Arbeitscharakteristika der einzelnen Glieder des Regelkreises werden besprochen.
    Notes: Abstract A newly developed system of $$p_{a_{CO_2 } } $$ -controlled automatic ventilation is demonstrated. ApCO 2-catheter electrode is used to monitor arterialpCO 2 continuously. The output voltage of thepCO 2 amplifier is fed into a regulator amplifier that compares it with a set voltage. The output voltage of the regulator controls an automatic respirator. All details of the automatic ventilation are described.

    Die Aussagefähigkeit des LPI nach E. A. Müller bei der Beurteilung der körperlichen Leistungsfähigkeit von Trainierten und Untrainierten (1971)

    Description / Table of Contents: Zusammenfassung Um zu prüfen, ob sich der LPI-Wert von Sportlern wesentlich von den aus der Literatur bekannten Werten für Untrainierte unterscheidet, wurde der LPI an zwei Kollektiven von Spitzen-Radsportlern und Sportstudenten bestimmt. Die Ergebnisse zeigen, daß der Mittelwert von 11 Radsportlern (2,84 ± 0,36) und von 24 Sportstudenten (2,66 ± 0,65) im Bereich des von E. A. Müller mit 2,8 ± 0,6 angegebenen Mittelwerts für „normale Männer” liegt. Der LPI scheint weitgehend trainingsresistent zu sein, daher kann man die körperliche Dauerleistungsfähigkeit von Versuchspersonen unterschiedlichen Trainingszustands nicht mit dem LPI erfassen. Da andererseits ein Zusammenhang zwischen einem kleinen LPI-Wert und einer guten körperlichen Leistungsfähigkeit anzunehmen ist, könnte der LPI ein Maß für die Eignung (Talent) zu körperlicher Ausdauerleistung sein.
    Notes: Summary The LPI values from sportsmen should be compared with those given in the literature. Therefore the LPI was determined in 11 top racing cyclists and 24 students of sport, using the typical method from E. A. Müller. The LPI means were showing no essential difference between the trained subjects (cyclists: 2.84 ± 0.36, students 2.66 ± 0.65) and untrained, especially the LPI value from E. A. Müller for “normale Männer” (2.8 ± 0.6). The LPI seems to be independent of training; therefore the physical fitness of subjects with variing state of training cannot be compared using the LPI. On the other hand a connection between a small LPI value and a good physical fitness can be supposed. Therefore it might be possible, that the LPI is a measure for the congenital talent to the ability for endurance strain.

    Methodical aspects of perceived exertion rating and its relation to pedalling rate and rotating mass (1975)
    Springer

    ISSN: 1439-6327
    Keywords: Perceived Exertion Rating ; Pedalling Rate ; Methods in Ergometry ; Psycho-Physiology in Effort
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract Methodical aspects of the relationship between pedalling rate and rotating mass and perceived exertion rating (PER; Borg, 1962) were studied in trained, untrained, and ill subjects in bicycle ergometry. Pedalling rate varied between 40 and 100 rpm, work load steps were 5, 10, 15 and 20 mkp/sec in the healthy subjects, and 2.5, 5, 7.5 and 10 mkp/sec in the patients. PER decreased with increasing pedalling rate in all healthy subjects. In the patients, PER increased moderately at work load of 2.5 mkp/sec, but decreased at higher work loads up to 80 rpm, followed by a slight increase at 100 rpm. Higher mass of the flywheel, studied in 6 trained subjects, lowered the PER insignificantly. In the healthy subjects, test criteria, such as reproducibility, reliability, sensitivity, and linearity remained almost unaffected by pedalling rate. In patients, increasing pedalling speed diminished reproducibility and sensitivity. The strictness of the PER work load relationship is lowered at higher pedalling rate, especially at 100 rpm. When using the PER scale, pedalling rate has to be considered as an factor of main influence.

    Heart rate and perceptual response to exercise with different pedalling speed in normal subjects and patients (1977)
    Springer
    European journal of applied physiology 37 (1977), S. 297-304 
    Details
    ISSN: 1439-6327
    Keywords: Bicycle ergometry ; Perceived exertion ; Pedalling rate
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary The perceived exertion rating (RPE) scale of Borg was used to investigate the relationship between perceived exertion and pedalling rate. Normal subjects and patients with chronic obstructive lung disease (Cold) were studied in repeated test series. Work load, applied in a random order, varied from 2.5 to 10 mkp/s (patients) and 5 to 20 mkp/s (normals). Pedalling rate varied from 40 to 60, 80, 100 rpm. At constant work load, RPE decreases during increasing pedalling rate. With respect to validity, RPE, showing a closer relationship to work load than to heart rate, seems to reflect perception of physical stress rather than perception of physiological strain. In addition, the results raise the question of standardization of pedalling rate in bicycle ergometry.
