The paper presents some data on the structure of the systole of the right ventricle obtained by means of kinetocardiography in 280 sportsmen, aged 12-14 years, with different functional states of their organisms (non-trained, poorly and well-trained, with chronic overstraining of the heart), as well as some data on the level of the systolic pressure in the pulmonary circulation system (by the Buzstin method) at rest and during the restorative period after exercises (test of the Leningrad Institute of Physical Culture, bycycle tests). The more the organism is trained, the more distinct the stages ofthe syndrome of regulated myocardial hypodynamia were found to be, a moderate hyperfunctionof the heart is noted during physical exercises that is accompanied by slight elevations of the pressure in the pulmonary system. In cases of chronic cardiac overstraining myocardial hypodynamia, stage I--II, was found, pressure elevation in the pulmonary circulation system -- in 21.4% of the examined persons at rest, its sharp elevation after exercises (up to 78.6 mm Hg) and prolongation of the restorative period. The obtained data demonstrate the perfection of the function of the right ventricle and of the pulmonary circulation under systematic training in the adolescents, and their deterioration in cases of chronic overstraining of the heart.
本文介绍了通过心动描记法获得的280名12至14岁运动员右心室收缩结构的数据，这些运动员机体功能状态各异（未受过训练、训练不足和训练良好、心脏有慢性过度劳损），还介绍了静息时以及运动后恢复期间肺循环系统收缩压水平的数据（采用布兹斯汀法，列宁格勒体育学院的测试，自行车测试）。机体训练程度越高，调节性心肌功能减退综合征的各阶段越明显，体育锻炼时会出现心脏适度功能亢进，同时伴有肺系统压力略有升高。在心脏慢性过度劳损的情况下，发现有I-II期心肌功能减退，肺循环系统压力升高——21.4%的受检者静息时出现，运动后压力急剧升高（高达78.6毫米汞柱）且恢复时间延长。所得数据表明，青少年经过系统训练后右心室和肺循环功能完善，而心脏慢性过度劳损时功能会恶化。
