At the Olympic level, optimally distributing training intensity is crucial for maximizing performance.
The authors evaluated the effect of training-intensity distribution on anaerobic power as a substitute for 1500-m speed-skating performance in the 4 y leading up to an Olympic gold medal.
During the preparation phase of the speed-skating season, anaerobic power was recorded periodically (n = 15) using the mean power (in watts) with a 30-s Wingate test. For each training session in the 4 wk prior to each Wingate test, the volume (in hours), training type (specific, simulation, nonspecific, and strength training), and the rating of perceived exertion (RPE; CR-10) were recorded.
Compared with the 8 lowest, the 7 highest-scoring tests were preceded by a significantly (P < .01) higher volume of strength training. Furthermore, the RPE distribution of the number of nonspecific training sessions was significantly different (P < .01). Significant (P < .05) correlations highlighted that a larger nonspecific training volume in the lower intensities RPE 2 (r = .735) and 3 (r = .592) was associated positively and the medium intensities RPE 4 (r = -.750) and 5 (r = -.579) negatively with Wingate performance.
For the subject, the best results were attained with a high volume of strength training and the bulk of nonspecific training at RPE 2 and 3, and specifically not at the adjoining RPE 4 and 5. These findings are surprising given the aerobic nature of training at RPE 2 and 3 and the importance of anaerobic capacity in this middle-distance event.
在奥运级别,最佳地分配训练强度对于最大化表现至关重要。
作者评估了训练强度分布对作为 1500 米速度滑冰表现替代指标的无氧能力的影响,这是在获得奥运金牌前的 4 年的速度滑冰赛季准备阶段。
在速度滑冰赛季的准备阶段,周期性地(n = 15)使用 30 秒的瓦格纳测试中的平均功率(瓦特)记录无氧能力。对于每个瓦格纳测试前的 4 周内的每个训练课程,记录了量(小时)、训练类型(专项、模拟、非专项和力量训练)和感觉努力评分(RPE;CR-10)。
与得分最低的 8 次相比,得分最高的 7 次测试前进行了显著(P <.01)更多的力量训练。此外,非专项训练次数的 RPE 分布明显不同(P <.01)。显著(P <.05)的相关性强调,RPE 2(r =.735)和 3(r =.592)的较低强度的更大非专项训练量与瓦格纳表现呈正相关,而 RPE 4(r = -.750)和 5(r = -.579)的中等强度则与瓦格纳表现呈负相关。
对于研究对象来说,取得最佳结果的方法是进行大量的力量训练和非专项训练,主要集中在 RPE 2 和 3,而不是相邻的 RPE 4 和 5。考虑到 RPE 2 和 3 的有氧性质以及无氧能力在这个中距离项目中的重要性,这些发现令人惊讶。
