On 15 male healthy sports students the influence of a one-legged aerobical and anaerobical ergometer training was investigated. The training period lasted six weeks. The parameters recorded were oxygen uptake (VO2), respiratory minute volume (VE), heart rate (HF), the behaviour of lactic acid (La) and the aerobic-anaerobic threshold (AAS, 4 mmol/l). An incremental test on bicycle-ergometer was carried out with the trained leg as well as with both legs. Group I trained four times a week, 35 minutes daily with an intensity of 2-3 mmol/l lactic acid. Group II carried out a modified form of interval training to the same extent in which the physical strain lasted five times three minutes with a three minutes brake each time and the concentration of lactic acid was 6-8 mmol/l. The main results are: In both groups work intensity, work intensity per kg bodyweight, maximal oxygen uptake and the aerobic-anaerobic threshold were increased. The alterations in group II were clearer as in group I. The results indicate that in this case the anaerobic training had more favourable effect on metabolism providing energy than the aerobic training. Verf.-Referat
