Rice, PE, Gurchiek, RD, and McBride, JM. Physiological and biomechanical responses to an acute bout of high kicking in dancers. J Strength Cond Res 32(10): 2954-2961, 2018-High-kick precision competitive dance involves the integration of kicking inline, jumping, and turning during a 3-minute routine and causes a disturbance to both aerobic and anaerobic systems. However, no known study has quantified the effect of a hick-kick-specific protocol on blood lactate (BL), heart rate (HR), and countermovement jump (CMJ) performance. A group of adolescent high-kick dancers (n = 20; age = 15.0 ± 1.8 years; height = 161.5 ± 8.2 cm; body mass = 56.3 ± 11.0 kg; and dance team/weight lifting experience = 2.1 ± 0.9 years) participated in this investigation. Participants' BL was collected, and 3 CMJ trials were performed before (PRE) and after (POST) completing the high-kick protocol. The high-kick protocol consisted of intermittent running and kicking in place for a total of 1:45 at a tempo of 160 b·min, while average and peak HR (HRavg; HRpeak) were recorded. Jump height (JH), maximal trunk flexion (MTF), take-off angle (TOA), and relative peak power (PP) were determined from PRE and POST CMJ trials. During kicking, HRavg and HRpeak (n = 13) were 172.4 ± 15.7 b·min and 207.0 ± 23.0 b·min, respectively. Dancers' (n = 20) BL significantly (p ≤ 0.05) increased from 1.5 ± 0.5 to 8.6 ± 1.5 mmol·L, and JH and PP significantly decreased from 0.42 ± 0.08 to 0.36 ± 0.04 m and 41.3 ± 5.5 to 38.5 ± 4.0 W·kg, respectively, from PRE to POST. No significant changes occurred in MTF and TOA measurements from PRE to POST. The demands introduced during a high-kick-specific protocol can therefore be recognized as a metabolic and mechanical stimulus for fatigue; however, esthetics seem to be unaffected. Such findings may indicate that this modality of dance necessitates supplemental strength and conditioning training similar to other sports to sustain the loads of high-kick dance.
赖斯，PE，格丘克，RD，和麦克布莱德，JM。舞蹈运动员急性踢腿运动的生理和生物力学反应。J 力量与调理研究 32（10）：2954-2961，2018-高踢精确竞技舞蹈涉及在 3 分钟的常规动作中结合直踢、跳跃和转身，同时对有氧和无氧系统造成干扰。然而，尚无已知研究量化高踢特定方案对血乳酸（BL）、心率（HR）和反向跳（CMJ）表现的影响。一组青少年高踢舞者（n = 20；年龄= 15.0 ± 1.8 岁；身高= 161.5 ± 8.2 厘米；体重= 56.3 ± 11.0 公斤；舞蹈队/举重经验= 2.1 ± 0.9 年）参加了这项研究。参与者的 BL 被收集，并且在完成高踢方案之前（PRE）和之后（POST）进行了 3 次 CMJ 试验。高踢方案由间歇跑步和原地踢腿组成，共 1:45 分钟，节奏为 160 b·min，同时记录平均和峰值 HR（HRavg；HRpeak）。从 PRE 和 POST CMJ 试验中确定了跳跃高度（JH）、最大躯干屈曲（MTF）、起飞角度（TOA）和相对峰值功率（PP）。在踢腿时，HRavg 和 HRpeak（n = 13）分别为 172.4 ± 15.7 b·min 和 207.0 ± 23.0 b·min。舞者（n = 20）的 BL 显着（p ≤ 0.05）从 1.5 ± 0.5 增加到 8.6 ± 1.5 mmol·L，JH 和 PP 显着从 0.42 ± 0.08 降低到 0.36 ± 0.04 m 和 41.3 ± 5.5 到 38.5 ± 4.0 W·kg，分别从 PRE 到 POST。从 PRE 到 POST，MTF 和 TOA 测量值没有显着变化。因此，高踢特定方案引入的需求可以被认为是疲劳的代谢和机械刺激；然而，美学似乎没有受到影响。这些发现可能表明，这种舞蹈形式需要类似其他运动的补充力量和调理训练，以维持高踢舞蹈的负荷。
