Objective: The purpose of this study was to examine adverse cardiovascular events that occurred as result of resistance training within combined resistance-endurance training sessions in a cardiac residential rehabilitation (CR) program.
Material/Methods: Nine-hundred-ninety-six patients (204 women, age 65 yrs and 792 men, age 62 yrs) completed a combined resistance-endurance training consisting of 5±2 resistance training-sessions (50% of the one repetition maximum, 2-3 sets of 12-15 repetitions each, engaging 10 different muscle groups) and 15±4 endurance training-sessions consisting of 50-60% of maximal leg power (Pmax) on cycle ergometer, lasting 10-18 minutes per training session.
Results: 28 patients exhibited adverse effects associated with resistance training sessions 4 hypoglycemia and 24 cardiovascular complications. Of those, 9 presented hypertension, 11 hypotension, 2 atrial fibrillation, 1 angina pectoris, 1 bradycardia and 16 further adverse effects that were not directly connected to training sessions (5 acute respiratory illnesses and/or influenza infections, 4 angiography, 3 vertigo, 2 diarrhea, 1 pleural effusion, 1 venous patch).
Conclusion: Our findings suggest that complications of the cardiovascular system are rare and appear to be mild during a 4 weeks lasting combined resistance-endurance training program.
