The aim of the present study was to investigate whether the physiological parameters indicative of cardiorespiratory fitness obtained during the 30-15 intermittent fitness (30-15IFT) test and the multistage laboratory treadmill endurance (TR) test differ. Nineteen elite handball players were recruited for the current study and assigned in a cross-over manner to one of two tests to be performed 48 h apart at each visit to the testing facility. The results showed that VO2max (percentage difference [PC] = 6.1%; p = 0.004) and maximal running velocity (V) (PC = 19.4%; p < 0.001) were significantly higher for the 30-15IFT test than that obtained during the TR test. Furthermore, the onset of blood lactate accumulation was shown to be significantly higher for all measures considered to predict it during 30-15IFT compared to TR as follows: VO2max (PC = 12.6%; p = 0.001), running speed (PC = 33.9%; p < 0.001), and maximal heart rate (PC = 7.5%; p < 0.001). The current study highlights the importance of sport-specific testing, particularly for measuring individual cardiorespiratory fitness in elite handball players, as TR may underestimate crucial variables used for both diagnostics and training prescription.
本研究旨在探讨 30-15 间歇式体能测试（30-15IFT）和多阶段实验室跑步机耐力测试（TR）中获得的心肺适能生理参数是否存在差异。本研究招募了 19 名精英手球运动员，以交叉方式分配到两种测试中，每次到测试地点进行测试时，两种测试相隔 48 小时。结果表明，30-15IFT 测试的 VO2max（百分比差异 [PC] = 6.1%；p = 0.004）和最大跑步速度（V）（PC = 19.4%；p < 0.001）明显高于 TR 测试。此外，与 TR 相比，30-15IFT 中所有用于预测其的指标的血乳酸积累起始点均明显较高，如下所示：VO2max（PC = 12.6%；p = 0.001）、跑步速度（PC = 33.9%；p < 0.001）和最大心率（PC = 7.5%；p < 0.001）。本研究强调了特定于运动的测试的重要性，特别是在测量精英手球运动员的个体心肺适能方面，因为 TR 可能会低估用于诊断和训练处方的关键变量。
