Dance is physically demanding and results in blood lactate (BL) accumulation and elevated Heart Rate (HR). Researchers recommend using either Active Recovery (AR; eg, low-to-moderate intensity-exercise) or Passive Recovery (PR; eg, complete rest) modes after activity. We compared BL and HR responses between AR or PR over a 15-minute recovery period following a Kathak dance. Twelve female dancers (31.0 ± 6.0 years; 161.5 ± 4.9 cm; 55.5 ± 5.8 kg) performed 2 dance testing sessions (Day 1 = AR, Day 2 = PR) 48 hours apart. Each session started with a 10-minute warm up followed by dancers performing four 2-minute stages of Kathak dance, with three 1-minute periods between stages where we recorded HR and their Rate of Perceived Exertion (RPE:scale = 6-20) to match the intensity of both sessions. Post-dance, we recorded dancers' BL and HR at 1, 3, 5, 10, and 15 minutes while they recovered via AR or PR. Separate 2(mode) × (time) Repeated-Measures-ANOVA followed by simple-main-effects testing and adjusted Bonferroni-pairwise-comparisons examined differences in BL and HR responses across modes and time(α = .05). Dancers' HR and RPE were similar across sessions. No mode × time interaction existed in BL ( = 3.6, = .06). BL levels were similar across modes ( = 0.5, = .5). BL levels reduced over time ( = 6.0, = .02), but Bonferroni-comparisons did not reveal any pairwise differences. In HR a significant mode*time interaction ( = 11.0, = .01, η = .55) was observed. Both Active and Passive recovery modes achieved absolute HR levels by 15 minutes, with PR mode stabilizing within 5 minutes. Over a 15-minute recovery period after Kathak dance, dancers' BL and HR responses were similar across time in both AR and PR, with HR being higher in AR. Dancers' HR remained similar from 1 to 3 minute post dance recovery and then dropped over time. Thus, dancers can rest up to 3 minutes and still maintain the same elevated HR. Overall, dancers can choose either AR or PR as their recovery mode based on their individual preferences.
舞蹈对身体要求很高，会导致血乳酸（BL）积累和心率（HR）升高。研究人员建议在活动后使用主动恢复（AR；例如，低到中等强度的运动）或被动恢复（PR；例如，完全休息）模式。我们比较了在 Kathak 舞蹈后 15 分钟的恢复期内，AR 或 PR 对 BL 和 HR 反应的影响。12 名女性舞者（31.0±6.0 岁；161.5±4.9 厘米；55.5±5.8 公斤）在相隔 48 小时的两天进行了 2 次舞蹈测试。每次测试都以 10 分钟的热身开始，然后舞者进行 4 个 2 分钟的 Kathak 舞蹈阶段，每个阶段之间有 3 个 1 分钟的阶段，在此期间我们记录 HR 和他们的感觉用力程度（RPE：量表=6-20）以匹配两个阶段的强度。跳舞后，我们在 AR 或 PR 时记录舞者的 BL 和 HR 在 1、3、5、10 和 15 分钟时的恢复情况。采用 2（模式）×（时间）重复测量方差分析，然后进行简单主效应检验和调整后的 Bonferroni 配对比较，以检验不同模式和时间下 BL 和 HR 反应的差异（α=0.05）。舞者在整个会话中 HR 和 RPE 相似。BL 中没有模式×时间的相互作用（F=3.6，P=.06）。两种模式的 BL 水平相似（F=0.5，P=.5）。BL 水平随时间降低（F=6.0，P=.02），但 Bonferroni 比较没有显示出任何成对差异。在 HR 中观察到显著的模式*时间交互作用（F=11.0，P=.01，η=0.55）。在 15 分钟内，主动和被动恢复模式均达到了绝对 HR 水平，PR 模式在 5 分钟内稳定。在 Kathak 舞蹈后 15 分钟的恢复期内，AR 和 PR 中舞者的 BL 和 HR 反应在整个时间内相似，AR 中的 HR 更高。舞者的 HR 在舞蹈后 1 分钟至 3 分钟的恢复期内保持相似，然后随时间下降。因此，舞者可以休息 3 分钟，仍然可以保持相同的升高的 HR。总体而言，舞者可以根据个人喜好选择 AR 或 PR 作为恢复模式。
