The aim of this study was to implement and validate the LMT in rowing due to considerable advantages for athletes and coaches compared to other established testing concepts in rowing. Twenty healthy and experienced male rowers completed two LMTs, one 2,000 m all-out trial and several endurance tests for MLSS （maximal lactate steady-state） determination on a rowing ergometer. For all tests performance, VO2, heart rate and lactate concentration were monitored. CV （coefficients of variation） for performance, heart rate and VO2 were all below 3.5% indicating a high reproducibility for these parameters at LM （lactate minimum） as well as at LMTpeak. Only lactate concentrations were revealed not to be well reproducible （CV 〉 12%）. Performance at LM and MLSS showed a significant correlation （r2 = 0.660; P 〈 0.001）. Comparison between data at LMTpeak and the 2,000 m time trial revealed a high correlation between performance and VO2peak data （performance： r2 = 0.923; P 〈 0.001, VO2peak： r2 = 0.860; P 〈 0.001）. We conclude that the present LMT protocol allows assessment of VO2peak, MLSS and prediction of 2,000 m race performance based on one single test. Therefore, our LMT protocol represents a reliable and valid diagnostic tool for steering and monitoring the training process in rowing.展开更多
