The purpose of this study was to evaluate the effects of two different rest intervals (2 min and 3 min), between two consecutive sets of repeated sprint skating ability (RSSA) tests, on the repeated sprint ability of ice hockey Forwards and Defensemen. Two protocols of RSSA tests, RSSA-2 and RSSA-3, were completed by 16 ice hockey Forwards and 8 Defensemen. Defensemen were heavier (p < 0.05) than Forwards, although their % body fat did not differ significantly. In RSSA-2, athletes performed six sets of 3×80 m sprint skating with 2 min passive recovery between two consecutive sets. In RSSA-3, the rest interval between the sets was 3 min. Average speed, average heart rate (HR), blood lactate concentration ([BLa]), and the rate of perceived exertion (RPE) were measured in both RSSA-2 and RSSA-3 tests. Both Forwards and Defensemen skated faster in RSSA-3 than in the corresponding set of RSSA-2. Forwards were faster than Defensemen in both the tests, however, the difference was significant (p < 0.05) only in RSSA-2. In Forwards and Defensemen, HR increased gradually from set 1 through set 6 in RSSA-2 and RSSA-3. In most of the sets, RPE was higher in RSSA-2 than in RSSA-3, and Defensemen perceived higher exertion than Forwards. No difference in [BLa] was noted between Forwards and Defensemen, although players of both positions showed higher [BLa] in RSSA-3 than in RSSA-2. This study concludes that (1) Forwards skate faster than Defensemen, (2) average heart rate and [BLa] do not vary between Forwards and Defensemen, and (3) a higher perceived exertion is observed in Defensemen than Forwards during repeated sprint skating tests.
本研究的目的是评估在两组连续的重复短距离速滑能力（RSSA）测试之间设置两种不同的休息间隔（2分钟和3分钟），对冰球前锋和后卫重复冲刺能力的影响。16名冰球前锋和8名后卫完成了两种RSSA测试方案，即RSSA - 2和RSSA - 3。后卫比前锋体重更重（p < 0.05），尽管他们的体脂百分比没有显著差异。在RSSA - 2中，运动员进行六组3×80米的短距离速滑，两组连续之间有2分钟的被动恢复时间。在RSSA - 3中，组间休息间隔为3分钟。在RSSA - 2和RSSA - 3测试中均测量了平均速度、平均心率（HR）、血乳酸浓度（[BLa]）和主观用力感觉等级（RPE）。前锋和后卫在RSSA - 3中的滑行速度均比RSSA - 2相应组更快。在两项测试中，前锋都比后卫速度更快，然而，仅在RSSA - 2中差异显著（p < 0.05）。在前锋和后卫中，HR在RSSA - 2和RSSA - 3中从第1组到第6组逐渐升高。在大多数组中，RSSA - 2中的RPE高于RSSA - 3，并且后卫比前锋感觉用力程度更高。尽管两个位置的运动员在RSSA - 3中的[BLa]均高于RSSA - 2，但前锋和后卫之间的[BLa]没有差异。本研究得出结论：（1）前锋滑行速度比后卫快；（2）前锋和后卫的平均心率和[BLa]没有差异；（3）在重复短距离速滑测试中，后卫比前锋主观用力感觉更高。
