Dynamics of cardiac performance in athletes during isometric exercise
      
The main structural-functional indices of cardiac performance during isometric exercise were recorded in athletes and non-athletes.
      
The physiological shifts in response to exercise were less obvious in the athletes than in the non-athletes.
      
The objective of this paper is to study the effect of different regimens of interval hypoxia on the cardiorespiratory and hematological functions of athletes in order to use the data obtained to optimize interval hypoxic training.
      
Specific features of the mechanisms and regularities of adaptation to exercise were studied in athletes over 15 years.

Systolic time intervals ( STI ) and heart rates ( HR ) were measured by a non-invasive method ( the electrical impedance method ) before, immediately after 4-minute bicycle exercise at 2 separate ( 50 W and 150 W ) work loads and during the recovery period in 40 young students and 40 athletes. At rest the HR was lower ( P<0.01 ) and QSt was longer (P<0.05)and the ratio PEP/LVET was larger (P<0.05 and P<0.01 ) and LVETc was shorter ( P<0.001 ) in the athletes. Immediately after cessation of exercise...

Systolic time intervals ( STI ) and heart rates ( HR ) were measured by a non-invasive method ( the electrical impedance method ) before, immediately after 4-minute bicycle exercise at 2 separate ( 50 W and 150 W ) work loads and during the recovery period in 40 young students and 40 athletes. At rest the HR was lower ( P<0.01 ) and QSt was longer (P<0.05)and the ratio PEP/LVET was larger (P<0.05 and P<0.01 ) and LVETc was shorter ( P<0.001 ) in the athletes. Immediately after cessation of exercise the mean values of QS2, LVET, PEP, IVCT, QS,, and PEP/LVET decreased and those of HR and LVETc increased in both the young students and athletes. However, the degree of QSZ and L\ ET shortening and HR rising in the athletes was not as great as in the young students, but the degree of the ratio PEP/LVET falling and LVETc rising was greater in the athletes. The speed of return toward control of all the indices except the ratio PEP/LVET was load-dependent throughout recovery. The recovery in the athletes was faster , particularly after exercise at 150 Watts. This study shows that 1 ) impedance cardiography is a useful method for evaluating changes in STI during exercise and 2 ) regular physical training improves the pump performance and en hances the contractility of the heart and promotes the adjusting speed of the heart to exercise.

用无创法(阻抗法)测量了40名青年学生和40名运动员在两种运动负荷(50W和150W)运动前、运动后即刻和恢复时程的收缩时间间期(STI)和心率(HR)。在静态时,“运动员组”的心率较缓(P<0.01)、QS_1较长(P<0.05)、PEP/LVET比值较大(P<0.05和P<0.01)、LVETc较短(P<0.001)。运动后即刻,“学生组”和“运动员组”都表现为QS_z、LVET、PEP、IVCT、QS_1缩短、PEP/LVET比值减小、心率增速和LVETc延长。但“运动员组”QS_2、LYET的缩短和心率增速的程度较少,而PEP/LVET比值的减小和LVETc延长的程度较大。除PEP/LVET比值外,其余各项指标的恢复速度均与负荷量有关。“运动员组”的恢复速度较快,尤其在150W时更为明显。本文指出:1)用阻抗法测算动态下的STI更为实用;2)系统训练可提高心脏活动的潜力,改善泵功能,促进心脏活动的调节速度。

29 males were involved in the study to investigate the effect of short and long term weightlifting training on the strength per unit cross-sectional area, muscle fiber and the relationship between the both. 9 young players who had some training background were arraned in a weightlifting trainging program six times a wk for 10 wk.The muscle cross-sectional area of the thigh were measured with computed tomography scanning, muscle biopsies were taken from vastus lateralis to distinguish percentage and average area...

29 males were involved in the study to investigate the effect of short and long term weightlifting training on the strength per unit cross-sectional area, muscle fiber and the relationship between the both. 9 young players who had some training background were arraned in a weightlifting trainging program six times a wk for 10 wk.The muscle cross-sectional area of the thigh were measured with computed tomography scanning, muscle biopsies were taken from vastus lateralis to distinguish percentage and average area of muscle fiber type I and I ,and maximal voluntary isometric torque of knee extension were measured before and after the training. The results were compared with that of control group ( 13 nonathletes ) and elite athletes group < 7 national weightlifting players ).It was found the strength per unit cross-sectional area of the muscle in the trained groups ( before, after and elite ) was higher significantly than that of the controls. That is to say, there is a difference in the strength per unit cross-sectional area of the muscle between nonathletes and trained players. After shorthand long term weightlifting training, direct correlation appeared between the strength per unit cross-sectional area of the muscle and type 11%, muscle fiber distribution had not been changed with short and long term weightlifting training.The high load weightlifting training hadselective effects on type I regardless of age. It is concluded that the speciality of the training program has influenceon the strength per unit cross-sectional area of the muscle, muscle fiber and the relationship between the strength per unit cross-sectional area of the muscle and muscle fiber type.

安排9名有一定训练的青少年运动员参加10周举重训练。每周6次,每次8小时。训练前后用电子计算机—X线断层扫描技术(CT)测量大腿肌肉横断面积,股外肌针刺活检取样测定Ⅰ、Ⅱ型肌纤维%和面积。测定大腿伸膝肌最大随意等长力量。将结果(实验前、后)与对照组(13名无训练者)和优秀举重运动员(健将3人、一级4人)进行比较。结果表明,有训练人(实验前、后和优秀)与没有训练人(对照)在肌比力上存有差别。短、长期举重训练后,肌比力与Ⅱ型肌纤维%呈正相关。短、长期举重训练不曾改变肌纤维类型分布。举重训练对Ⅱ型肌纤维有选择性作用,且这个作用不受年龄的影响。结果还提示,肌比力的变化及肌比力与肌纤维之间的关系都会受运动项目专项特点的影响。

The pump function of heart --- cardiac output (CO) and stroke volume (SV) were measured in20 athletes with arrhythmia and 10 athletes without arrhythmia at rest and after exercise by usingcardiac output computer which is based on the dye dilution method. The value of SV was similar to that reported by other authors determined by the Fick me-thod. At rest, the value of CO, SV and cardiac index (CI) in the male athletes with arrhythmia weresignificantly higher than those in the normal athletes...

The pump function of heart --- cardiac output (CO) and stroke volume (SV) were measured in20 athletes with arrhythmia and 10 athletes without arrhythmia at rest and after exercise by usingcardiac output computer which is based on the dye dilution method. The value of SV was similar to that reported by other authors determined by the Fick me-thod. At rest, the value of CO, SV and cardiac index (CI) in the male athletes with arrhythmia weresignificantly higher than those in the normal athletes (P<0.05). The circulation time of the normalathletes was longer than normal untrained. After exercise, the values of SV were increased in the no-rmal athletes but were decreased in those with arrhythmia. The results showed that the cardiac rese-rve was greater in normal athletes and the pump function of heart in athletes with arrhythmia waslower. The SV varied with different types of arrhythmia. When the changes of ECG during exercisewere considered together with the changes of SV, the properties of different arrhythmias could bedistinguished. The values of SV were increased right after exercise (P<0.05) in athletes with occa-sional premature beats which disappeared during exercise. In the athietes with atrial fibrillation, bilate-ral bundle branch block, Ⅲ A-VB, and frequent premature beats the values of SV decreased afterexercise while the ECG remained as it was or only change a little during exercise. The results sugge-sted that the pump function of heart and the physical performance were lower in the latter group ofathletes. The study of the values of CO and SV in athletes with arrhythmia may be used as criteriaof hemodynamics for arranging their training programs.

近年来由于训练强度不断增大,高水平运动员心律失常的发生率显著增加。本文研究资料表明,男心律失常组安静时心搏量明显大于正常组(P<0.05),而运动后心搏量降低(正常组心搏量增加),说明心律失常的运动员心脏储备能力差,心脏泵血功能降低,应予慎重对待。
