The purpose of this study was to compare the effects of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) utilizing a canoeing ergometer on endurance determinants, as well as aerobic and anaerobic performances among flat-water canoeists. Fourteen well-trained male flat-water canoeists were divided into an HIIT group or an MICT group. All subjects performed a continuous graded exercise test (GXT) and three fixed-distance (200, 500, and 1000 m) performance tests on a canoeing ergometer to determine canoeing economy, peak oxygen uptake (VOpeak), and power at VOpeak, and to calculate the critical velocity (CV) and anaerobic work capacity before and after the training programmes. The training programme involved training on a canoeing ergometer three times per week for four weeks. HIIT consisted of seven 2 min canoeing bouts at an intensity of 90% VOpeak separated by 1 min of rest. The MICT group was trained at an intensity of 65% VOpeak continuously for 20 min. After four weeks of training, performance in the 200-m distance test and the power at VOpeak significantly improved in the HIIT group; performance in the 500 m and 1000 m distances and CV significantly improved in the MICT group. However, all variables were not significantly different between groups. It is concluded that HIIT for four weeks is an effective training strategy for improvement of short-distance canoeing performance. In contrast, MICT improves middle-distance canoeing performances and aerobic capacity.
本研究旨在比较利用皮划艇测功仪进行的高强度间歇训练（HIIT）和中等强度持续训练（MICT）对静水皮划艇运动员耐力指标以及有氧和无氧运动表现的影响。14名训练有素的男性静水皮划艇运动员被分为HIIT组或MICT组。所有受试者在皮划艇测功仪上进行了一次连续递增运动测试（GXT）和三次固定距离（200、500和1000米）的性能测试，以确定皮划艇经济性、峰值摄氧量（VOpeak）和VOpeak时的功率，并计算训练计划前后的临界速度（CV）和无氧工作能力。训练计划包括每周在皮划艇测功仪上训练三次，共四周。HIIT包括七次2分钟的皮划艇训练，强度为VOpeak的90%，每次训练之间休息1分钟。MICT组以VOpeak的65%的强度持续训练20分钟。经过四周的训练，HIIT组在200米距离测试中的表现和VOpeak时的功率显著提高；MICT组在500米和1000米距离以及CV方面的表现显著提高。然而，两组之间所有变量的差异均无统计学意义。得出的结论是，四周的HIIT是提高短距离皮划艇表现的有效训练策略。相比之下，MICT可提高中距离皮划艇表现和有氧能力。
