Abstract des Autors
"Anaerobic threshold" (AT) was evaluated by using six different methods in 7 highly trained male Teakwondo athletes. The following methods were employed: I - Weltman's test, II - heart rate deflection point (HRdP), III - ventilatory threshold (VT), IV - respiratory quotient (RQ=1), V - lactate turnpoint (LT) and VI -onset of blood lactate accumulation (OBLA). They were classifed as field (F; Methods I and II) or laboratory tests (L; Methods III to VI) and as non-invasive (NI; Methods III and IV) or invasive (IN; Methods V and VI) ones. The athletes were subjected to an incremental, continuous cycle ergometer test until exhaustion. Cardiorespiratory variables were recorded throughout the exercise by using a computerized on-line system. Mean values of oxygen uptake (VO2) at AT obtained by methods I - VI were 82.2 +/- 5.6, 76.9 +/- 15.1, 57.1 +/- 4.5, 69.5 +/- 14.7, 72.1 +/- 15.4 and 81.1 +/- 14.2% of VO2max, respectively, or 93.0 +/- 2.4, 90.9 +/- 4.2, 84.4 +/- 5.5, 87.8 +/- 6.6, 88.9 +/- 7.4 and 92.9 +/- 5.2% of HRmax, respectively. Method III produced significantly (P<0.05) lower results than Methods I, II and VI. Also Methods F and L, or NI and IN, differed significantly from each other. The results demonstrate that different AT estimates cannot be used interchangeably as indices of training adaptation. Verf.-Referat
