Summary:
The objective of the work was to evaluate the effect of eight-week combined training on the
performance, aerobic capacity and basic haemodynamic parameters in patients with systolic
dysfunction of the left ventricle and to assess its safety. The investigation comprised 26 patients,
men mean age (x ± SD) 61.8 ± 11.1 years with coronarographically verified chronic ischaemic
heart disease and with a left ventricular ejection fraction lower than 40 % (EF 35 ± 4 %). Before
the beginning and after completion of the rehabilitation programme (eight weeks) a spiroergometric
examination was made, up to the symptom-limited maximum. Fitness elements were included
after 2 weeks of aerobic training. The lesson lasted 60 mins. and included warming up (10
mins.), aerobic load on an ergometer with an intensity of the load at the level of the anaerobic
threshold (20 mins.), the stage of fitness training on a combined training machine (20 mins)and
the relaxation stage (10 mins).In the fitness stage the patients started to exercise at the 30 % level,
after two weeks at the 60 % level 1-RM (one repetition maximum) The results showed after eightweek
combined training a significant (p < 0.05) increase of the maximum achieved performance
(from 104 ± 27 to 132 ± 32 W) in patients with systolic left ventricular dysfunction. There was
a significant increase in the capacity of the transport system expressed by the value of the maximum
oxygen uptake (from 1545 ± 312 to 1740 ± 359 ml.min-1) and MET (from 5.3 ± 1.3 to 6.0 ±
1.4).There was a significant decrease of the blood pressure at rest, systolic and diastolic, and of
the baseline value of the heart rate at rest and of the "product rate, pressure" - RPP. Changes in
the EF were not significant
