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.
对21名赛艇运动员在为期4个月的训练期前后进行了运动测试。测试了相同工作负荷下VO2、VT和特定通气量(Sp.V)差异的显著性。研究了相对VO2(Trel VO20 = VO2/体重)对最大工作量(Wmax)与VO2 max之间相关性的影响。在训练期后,所有工作负荷下的VO2均呈现出高度显著的增加。多元线性回归分析表明,相关系数从r = 0.65(单因素)增加到R = 0.95(多因素)。当考虑相对VO2以及Wmax时,关于最大运动的估计精度有显著提高。相对VO2max作为训练状态的一个参数,可以根据准确的训练史(具有直接心肺影响的训练总量=耐力型训练)来估计。结合Wmax,这个训练史可以纳入多元回归方程VO2max = 1060 + 6.3Wmax + 57.3相对VO2max。通过这些方法,包括测力计测试和训练史,即使是一名实习内科医生也能相当准确地估计运动能力。
