In spite of the well-known benefits that have been shown, few studies have looked at the practical applications of high-intensity interval training (HIIT) on athletic performance. This study investigated the effects of a HIIT program compared to traditional continuous endurance exercise training. 24 hockey players were randomly assigned to either a continuous or high-intensity interval group during a 4-week training program. The interval group (IG) was involved in a periodized HIIT program. The continuous group (CG) performed moderate intensity cycling for 45-60 min at an intensity that was 65% of their calculated heart rate reserve. Body composition, muscle thickness, anaerobic power, and on-ice measures were assessed pre- and post-training. Muscle thickness was significantly greater in IG (p=0.01) when compared to CG. The IG had greater values for both ∆ peak power (p<0.003) and ∆ mean power (p<0.02). Additionally, IG demonstrated a faster ∆ sprint (p<0.02) and a trend (p=0.08) for faster ∆ endurance test time to completion for IG. These results indicate that hockey players may utilize short-term HIIT to elicit positive effects in muscle thickness, power and on-ice performance.
尽管高强度间歇训练（HIIT）已显示出诸多益处，但很少有研究关注其在运动表现方面的实际应用。本研究调查了HIIT计划与传统持续耐力运动训练相比的效果。在为期4周的训练计划中，24名曲棍球运动员被随机分配到持续训练组或高强度间歇训练组。间歇训练组（IG）参与了一个周期性的HIIT计划。持续训练组（CG）以其计算心率储备的65%的强度进行45 - 60分钟的中等强度骑行。在训练前后评估身体成分、肌肉厚度、无氧功率和冰上测试指标。与CG相比，IG的肌肉厚度显著更大（p = 0.01）。IG在∆峰值功率（p < 0.003）和∆平均功率（p < 0.02）方面都有更高的值。此外，IG的∆冲刺速度更快（p < 0.02），并且在完成耐力测试时间的∆方面有更快的趋势（p = 0.08）。这些结果表明，曲棍球运动员可以利用短期HIIT在肌肉厚度、力量和冰上表现方面产生积极影响。
