- Abstract:
- In order to obtain a critical review of E.A. Müller's "Leistungspulsindex", we worked out a functional representation of that index, using a simple physiologic-mathematic model of the oxygen transport system. We found that the LPI is influenced by the economy of the oxygen transport system and that it is inversely proportional to stroke volume, caloric coefficient, and to the efficiency of muscular work. Based on the theoretic analysis we tried to interpret the results of an investigation carried out with pupils of an coeducative intermediate school (years of birth 1964, 1965, 1966). We obtained statistically significant correlations (p less than 0.1%) between LPI and parameters characterizing performance capacity (PWC170, heart rate at 100 W work load) and between LPI and body weight. The results of both the theoretic and experimental investigation indicate a dependence of the LPI on factors influenced by physical training processes, but no evidence was found, however, on an interrelationship between LPI and congenital factors of physical performance.
