Eight highly trained middle-distance runners (1500 m personal best 4:01.4 ± 0:09.2 min) completed two 7-day tapers, separated by at least 3 weeks of regular training: () prescribed using prediction models from elite middle-distance runners, where continuous running volume was reduced by 30% and interval intensity was equal to 1500 m race pace (RP); and () continuous running volume was reduced by 60% and intensity of the final interval session was completed at 110% of 1500 m race pace (HI). Performance was assessed using 1500 m time trials on an indoor 200 m track 1 day before, and 1 day after each taper. Performance time was improved after HI by 5.2 ± 3.7 s (mean ± 90% confidence limits, = 0.03) and by 3.2 ± 3.8 s after RP ( = 0.15). The first and second 300 m segments of the 1500 m time trial were faster post-taper in RP ( = 0.012 and = 0.017, respectively) and HI (both = 0.012). Running faster than race pace late in a low-volume taper is recommended to improve 1500 m track performance. A positive pacing strategy is adopted after tapering, although care should be taken to avoid an over-fast start. A large reduction in volume during tapering and an increase in final interval session intensity improves running performance. Athletes adopt a negative pacing strategy before tapering and a positive-pacing strategy after tapering.
八名经过严格训练的中长跑运动员(1500 米个人最佳成绩 4:01.4 ± 0:09.2 分钟)完成了两个为期 7 天的递减阶段,两个阶段之间至少间隔 3 周的常规训练:()按照精英中长跑运动员的预测模型进行规定,其中连续跑步量减少 30%,间歇强度等于 1500 米比赛配速(RP);()连续跑步量减少 60%,最后一个间歇阶段的强度以 1500 米比赛配速的 110%(HI)完成。在每个递减阶段之前和之后的一天,使用室内 200 米赛道的 1500 米计时赛来评估表现。HI 后,表现时间提高了 5.2 ± 3.7 秒(平均值 ± 90%置信区间, = 0.03),RP 后提高了 3.2 ± 3.8 秒( = 0.15)。在 RP( = 0.012 和 = 0.017,分别)和 HI(均为 = 0.012)中,1500 米计时赛的第一和第二 300 米段在递减后更快。在低量递减后期以比赛配速跑步被推荐用于提高 1500 米赛道表现。在递减后采用积极的配速策略,尽管应该注意避免过快的开始。在递减期间大量减少量和增加最后间歇阶段的强度可以提高跑步表现。运动员在递减前采用负配速策略,在递减后采用正配速策略。
