Abstract
The objective of this study was to determine the effects of isokinetic exercise on the cardiopulmonary system. Materials and Methods: We examined 11 healthy volunteers (2 females, 9 males, age: 24.4 ± 1.7 years, height: 1.83 ± 0.08 m, weight: 73.7 ± 10.5 kg) who participated in an isokinetic exercise (quadriceps curls) on the Cybex 6000 training & rehabilitation system. The training session consisted of 8 sets with 10 maximal repetitions and a break of 2 minutes between each set. Results: Maximal heart rate was 161.0 ± 11.1 bpm, maximal lactate concentration was within a range of 5.7 and 14.1 mmol/1 (8.6 ± 2.6 mmol/1), systolic blood pressure increased from 123.6 ± 7.4 at rest up to 174.5 ± 15.1 mmHg at maximal workload. Oxygen uptake rose from 525.6 ± 182.7 up to 2124.2 ± 513.8 ml/min, respiratory quotient ranged from 0.87 to 1.30. Torque maxima (195.2 ± 47.8 vs. 136.4 ± 32.9 Nm) and total physical work (2009.2 ± 573.5 vs. 1532.1 ± 383.4 J) of the extensor muscles were significantly higher (p<0.05) than those of the flexor muscles. Conclusion: The present data suggest that isokinetic exercise is associated with a relatively high strain on the cardiopulmonary system. Therefore, depending on age, predisposition to diseases of the cardiopulmonary system and overall fitness, the cardiovascular situation should be taken into account and the workload for isokinetic exercise should be carefully adapted to individual needs and reactions.
