The purpose of this study was to examine the effects of high-intensity interval training (HIT) and supramaximal interval training (SMIT) on indoor rowing performance; 20 male lightweight collegiate rowers (age = 21.77 ± 2.35 years, height = 178.4 ± 6 cm, body mass = 69.6 ± 3.1 kg) participated in this study. Baseline testing involved a 2,000-m time trial and incremental exercise test to determine VO2peak, peak power output (PPO), and power at 4 mmol·L blood lactate threshold. After the baseline tests, participants were allocated to SMIT or HIT intervention groups, which they performed 8 times over a 4-week period (2 times per week, 2 days apart). The SMIT involved 10 × 30-second intervals at 150% of the PPO with 4-minute rest. The HIT involved 8 × 2.5-minute intervals at 90% of the PPO with 3-minute rest. Of note, 5.7 and 5 seconds of improvements were observed in 2,000-m performance after SMIT and HIT interventions, respectively. Of note, 2,000-m time trial performance, 2,000-m power, PPO, relative, and absolute VO2peak were significantly improved after both training interventions. However, the differences between the groups were not significant. As a result, 4 weeks of SMIT improves 2,000-m rowing ergometer performance and related physiological variables in a similar fashion with HIT in collegiate rowers.
本研究的目的是检验高强度间歇训练（HIT）和超最大强度间歇训练（SMIT）对室内划船成绩的影响；20名男性大学轻量级赛艇运动员（年龄=21.77±2.35岁，身高=178.4±6厘米，体重=69.6±3.1千克）参与了本研究。基线测试包括2000米计时赛和递增运动测试，以确定最大摄氧量（VO2peak）、峰值功率输出（PPO）以及血乳酸阈值为4mmol·L时的功率。基线测试后，参与者被分配到SMIT或HIT干预组，在4周内进行8次训练（每周2次，间隔2天）。SMIT包括以PPO的150%进行10组30秒的间歇训练，每组间歇4分钟。HIT包括以PPO的90%进行8组2.5分钟的间歇训练，每组间歇3分钟。值得注意的是，SMIT和HIT干预后，2000米成绩分别提高了5.7秒和5秒。值得注意的是，两种训练干预后，2000米计时赛成绩、2000米功率、PPO、相对和绝对VO2peak均有显著提高。然而，两组之间的差异并不显著。因此，4周的SMIT训练对大学赛艇运动员2000米划船测功仪成绩及相关生理变量的改善效果与HIT相似。
