Among other aspects, aerobic fitness is indispensable for performance in slalom canoe.
To propose the maximal-lactate steady-state (MLSS) and critical-force (CF) tests using a tethered canoe system as new strategies for aerobic evaluation in elite slalom kayakers. In addition, the relationship between the aerobic parameters from these tests and the kayakers' performances was studied.
Twelve male elite slalom kayakers from the Brazilian national team participated in this study. All tests were conducted using a tethered canoe system to obtain the force records. The CF test was applied on 4 d and analyzed by hyperbolic (CF) and linear (CF) mathematical models. The MLSS intensity (MLSS) was obtained by three 30-min continuous tests. The time of a simulated race was considered the performance index.
No difference (P < .05) between CF (65.9 ± 1.6 N) and MLSS (60.3 ± 2.5 N) was observed; however, CF (71.1 ± 1.7 N) was higher than MLSS. An inverse and significant correlation was obtained between MLSS and performance (r = -.67, P < .05).
In summary, MLSS and CF tests on a tethered canoe system may be used for aerobic assessment of elite slalom kayakers. In addition, CF may be used as an alternative low-cost and noninvasive method to estimate MLSS, which is related with slalom kayakers' performance.
在诸多方面中，有氧适能对于激流回旋皮划艇运动表现而言不可或缺。
提出使用系留式皮划艇系统进行的最大乳酸稳态（MLSS）和临界力（CF）测试，作为精英激流回旋皮划艇运动员有氧评估的新策略。此外，还研究了这些测试中的有氧参数与皮划艇运动员表现之间的关系。
来自巴西国家队的12名男性精英激流回旋皮划艇运动员参与了本研究。所有测试均使用系留式皮划艇系统进行以获取力的记录。CF测试在4天内进行，并通过双曲线（CF）和线性（CF）数学模型进行分析。MLSS强度（MLSS）通过三次30分钟的连续测试获得。模拟比赛的时间被视为表现指标。
未观察到CF（65.9±1.6 N）和MLSS（60.3±2.5 N）之间存在差异（P<.05）；然而，CF（71.1±1.7 N）高于MLSS。MLSS与表现之间存在显著的负相关（r = -.67，P<.05）。
总之，在系留式皮划艇系统上进行的MLSS和CF测试可用于精英激流回旋皮划艇运动员的有氧评估。此外，CF可作为一种替代的低成本、非侵入性方法来估计与激流回旋皮划艇运动员表现相关的MLSS。
