研究铁人三项运动员在4周的减少训练量和增加训练强度后的生理和成绩变量的变化。研究方法：16名中等训练的铁人三项运动员被随机分配到2组：对照组（CON），遵循他们的常规训练，或高强度间歇训练（HITT）组，在4周的减少训练量期间每周完成2次HILT。HILT组的最大耗氧量（VO（2）max）显著增加（P = 0.03，d = 0.5），但CON组保持不变。HILT受试者第一和第二制动阈值的循环功率显著增加（P = 0.03，d = 1.0），CON受试者无变化（P = 0.57）。在模拟铁人三项测试中，两组的前后测骑行时间和平均功率没有变化（P > 0.05）。两组之间没有观察到显著的运行时间交互作用（P = .50）。结论：经过4周的HILT训练后，尽管训练时间总体上减少了，但在第一和第二次训练阈值时的VO（2）max和功率显著增加，而骑自行车和跑步的表现没有变化。在目前的研究中，只有在常规（高容量）训练的情况下，表现才有所改善。总而言之，为了提高跑步或骑自行车的表现，强烈建议进行大容量的训练计划。
To investigate changes in physiological and performance variables in triathletes following a 4-wk period of reduced training volume and increased training intensity. Methods: Sixteen moderately trained triathletes were randomly allocated to 2 groups: a control (CON) group, which followed their usual training, or a high-intensity interval training (HITT) group, which completed 2 HILT sessions per week during 4 wk of reduced training volume Results: Maximal oxygen consumption (VO(2)max) increased significantly in the HILT group (P = .03, d = 0.5) but remained unchanged in the CON group. Cycling power at first and second ventilatory thresholds increased significantly in the HILT subjects (P = .03, d = 1.0) and was unchanged in the CON participants (P = .57). During the simulated triathlon test, pretest-posttest cycling times and average power were unchanged in both groups (P > .05). No significant interactive effects between groups were observed for running time (P = .50). Conclusion: After a 4-wk HILT program, VO(2)max and power at first and second ventilatory thresholds were found to have increased significantly while cycling and running performance were unchanged, despite an overall reduction in training time. In the present study, performance was only shown to improve with usual (high-volume) training. Summarizing, in order to improve running or cycling performances, high-volume training programs are highly recommended.
