| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Cardiac cycle is divided to two phases, systolic and diastolic phase. Diastolic time (DT) correlates with the degree of coronary circulation. Systolic time (ST) is determined as interval of first heart sound (S1) and second heart sound (S2), DT is determined from the equation of [ RR interval-ST]. Obara et al have reported that ST and DT fit well a cubic regression equation in relation to RR interval that converged to the origin of the coordinates. The purpose of this study is to compare the percent of DT for RR interval (%DT) at the same HR during exercise among persons of different age and fitness. Subjects were 9 aged low fit persons (ALF), 8 aged high fit persons (AHF) and 8 young male students (YHF). The exercise test was performed on a cycle ergometer with an incremental loading method. %DT at HR 110 bpm was compared among three groups. At HR 110 bpm, the mean %DTs (SD) were 47.2 (2.2) %, 54.7 (4.9) %, 56.0 (1.5) % in three groups of ALF, AHF and YHF, respectively. The %DT in ALF were significantly lower than that in AHF and YHF. However, there was no significant difference of %DT between AHF and YHF. These results indicate that low fitness aged person appear to reach below 50% of %DT at HR 110 bpm. Furthermore these results demonstrate the importance of evaluating the cardiac diastolic time during exercise. | |
