The systematic management of training requires accurate training load measurement. However, quantifying the training of elite Australian rowers is challenging because of (a) the multicenter, multistate structure of the national program; (b) the variety of training undertaken; and (c) the limitations of existing methods for quantifying the loads accumulated from varied training formats. Therefore, the purpose of this project was to develop a new measure for quantifying training loads in rowing (the T2minute method). Sport scientists and senior coaches at the National Rowing Center of Excellence collaborated to develop the measure, which incorporates training duration, intensity, and mode to quantify a single index of training load. To account for training at different intensities, the method uses standardized intensity zones (T zones) established at the Australian Institute of Sport. Each zone was assigned a weighting factor according to the curvilinear relationship between power output and blood lactate response. Each training mode was assigned a weighting factor based on whether coaches perceived it to be "harder" or "easier" than on-water rowing. A common measurement unit, the T2minute, was defined to normalize sessions in different modes to a single index of load; one T2minute is equivalent to 1 minute of on-water single scull rowing at T2 intensity (approximately 60-72% VO2max). The T2minute method was successfully implemented to support national training strategies in Australian high performance rowing. By incorporating duration, intensity, and mode, the T2minute method extends the concepts that underpin current load measures, providing 1 consistent system to quantify loads from varied training formats.
系统的训练管理需要准确的训练负荷测量。然而，由于（a）国家计划的多中心、多州结构；（b）各种训练形式；以及（c）现有方法量化来自不同训练形式的负荷的局限性，量化精英澳大利亚赛艇运动员的训练是具有挑战性的。因此，本项目的目的是开发一种新的赛艇训练负荷量化方法（T2 分钟方法）。国家赛艇卓越中心的运动科学家和高级教练合作开发了该方法，该方法结合了训练持续时间、强度和模式，量化了单一的训练负荷指标。为了考虑不同强度的训练，该方法使用澳大利亚体育学院建立的标准化强度区（T 区）。每个区域都根据功率输出和血乳酸反应之间的曲线关系分配一个权重因子。根据教练认为它比水上划船“更难”或“更容易”，为每种训练模式分配一个权重因子。定义了一个常见的测量单位，T2 分钟，将不同模式下的训练归一化为单一负荷指标；一个 T2 分钟相当于 T2 强度下水上单人双桨划船 1 分钟（约 60-72%最大摄氧量）。T2 分钟方法成功地用于支持澳大利亚高性能赛艇的国家训练策略。通过结合持续时间、强度和模式，T2 分钟方法扩展了当前负荷测量所依据的概念，为从不同训练形式量化负荷提供了一个一致的系统。
