Several recent studies have reported substantial performance and physiological gains in well-trained endurance runners, swimmers, and cyclists following a period of high-intensity interval training (HIT). The aim of the current study was to compare traditional rowing training (CT) to HIT in well-trained rowers.
Subjects included 5 male and 5 female rowers (mean +/- SD; age = 19 +/- 2 y; height = 176 +/- 8 cm; mass = 73.7 +/- 9.8 kg; Vo2peak = 4.37 +/- 1.08 L.min-1). Baseline testing included a 2000-m time trial and a maximal exercise test to determine Vo2peak, 4-min all-out power, and 4 mmol.L-1 blood lactate threshold. Following baseline testing, rowers were randomly allocated to HIT or CT, which they performed seven times over a 4-wk period. The HIT involved 8 x 2.5-min intervals at 90% of the velocity maintained at Vo2peak, with individual recoveries returning to 70% of the subjects' maximal heart rate between intervals. The CT intensity consisted of workloads corresponding to 2 and 3 mmol.L-1 blood lactate concentrations. On completion of HIT or CT, rowers repeated the testing performed at baseline and were then allocated to the alternative training program and completed a crossover trial.
HIT produced greater improvements in 2000-m time (1.9 +/- 0.9%; mean +/- SD), 2000-m power (5.8 +/- 3.0%), and relative Vo2peak (7.0 +/- 6.4%) than CT.
Four weeks of HIT improves 2000-m time-trial performance and relative Vo2peak in competitive rowers, more than a traditional approach.
最近的几项研究报告称，经过一段时间的高强度间歇训练（HIT）后，训练有素的耐力跑者、游泳者和自行车运动员在运动表现和生理方面有显著提升。本研究的目的是比较训练有素的赛艇运动员进行传统赛艇训练（CT）和高强度间歇训练（HIT）的效果。
受试者包括5名男性和5名女性赛艇运动员（均值±标准差；年龄 = 19±2岁；身高 = 176±8厘米；体重 = 73.7±9.8千克；最大摄氧量 = 4.37±1.08升·分钟⁻¹）。基线测试包括2000米计时赛以及一次最大运动测试，以确定最大摄氧量、4分钟全力功率和4毫摩尔·升⁻¹血乳酸阈值。基线测试后，赛艇运动员被随机分配到高强度间歇训练组或传统训练组，在4周内每组进行7次训练。高强度间歇训练包括8组2.5分钟的间歇训练，强度为最大摄氧量时保持速度的90%，每组间歇期间个体恢复到受试者最大心率的70%。传统训练强度由对应2和3毫摩尔·升⁻¹血乳酸浓度的工作量组成。完成高强度间歇训练或传统训练后，赛艇运动员重复基线测试，然后被分配到另一种训练方案并完成交叉试验。
与传统训练相比，高强度间歇训练在2000米计时（提高1.9±0.9%；均值±标准差）、2000米功率（提高5.8±3.0%）和相对最大摄氧量（提高7.0±6.4%）方面有更大改善。
四周的高强度间歇训练比传统方法更能提高竞技赛艇运动员的2000米计时赛成绩和相对最大摄氧量。
