[Determination of maximal aerobic capacity using simple ergometry in various training conditions]

Exercise tests were performed in 21 competition rowers, before and after a 4 month training period. The significance of differences in VO2, VT, and specific ventilation (Sp. V) at equal work loads, were tested. The influence of the relative VO2 Trel VO20 = VO2/kg BW) on the correlation between maximal workload (Wmax) and VO2 max, was investigated. The VO2 at all workloads, showed a highly significant increase after the period of training. Multiple linear regression analysis, demonstrates an increase of the correlation coefficient from r = 0,65 (single) to R = 0,95 (multiple). The precision of estimation concerning maximal exercise, improves considerably when rel. VO2 is taken into account, as well as, Wmax. The rel. VO2max as a parameter for the state of training can be estimated from an exact training history (total amount of training with direct cardiopulmonary influence = endurance type of training). Combined with Wmax this training history can be included into the multiple regression equation VO2max - 1060 + 6.3 Wmax + 57.3 rel. VO2max. By these means, including ergometry and the training history, even a practicing internist can to a fair estent estimate the capacity for sport.
