The left ventricular systolic function was studied in 123 healthy men aged 23-24 years under the influence of exercise and during a two-hour restitution period. Left ventricular systolic time intervals (LVSTI) were evaluated by means of the Blumberger method with Holldack's modification before the exercise, immediately after its termination and after 30, 60 and 120 minutes. After exercise, a decrease was found in the absolute values of LVSTI and of the diastolic stage. During two-hour restitution, the authors found a decrease of left ventricular ejection time, total mechanical systolic time, total electromechanical systolic time, total ventricular electrical stimulation time and of the diastolic stage. A statistically highly significant decrease of all mentioned intervals was related to persisting, still after 2 hours, increased heart rate with which these intervals significantly correlated. The share (in percent) of LVSTI in the total cardiac cycle increased after exercise and was still increased after 2 hours following its termination. The relative increase of systolic time intervals was accompanied by a decrease in the duration of the diastolic stage.
对123名年龄在23至24岁的健康男性在运动影响下以及两小时恢复期间的左心室收缩功能进行了研究。在运动前、运动结束后即刻以及运动后30、60和120分钟，采用经霍尔达克改良的布伦伯格方法评估左心室收缩时间间期（LVSTI）。运动后，LVSTI的绝对值以及舒张期均出现下降。在两小时的恢复过程中，作者发现左心室射血时间、总机械收缩时间、总机电收缩时间、总心室电刺激时间以及舒张期均有所减少。所有上述间期的统计学高度显著下降与持续存在的心率增加有关，即使在2小时后心率仍增加，且这些间期与之显著相关。运动后LVSTI在整个心动周期中的占比（百分比）增加，且在运动结束后2小时仍保持增加。收缩时间间期的相对增加伴随着舒张期持续时间的减少。
