Seifert Gonzales, AM and Stenson, MC. Physiological demands of competitive collegiate dance. J Strength Cond Res 38(9): e503-e509, 2024-Competitive collegiate dance combines elements of gymnastics and acrobatics with more traditional styles, such as ballet, jazz, and modern dance. Assessing the physiological demands and identifying clear measures of intensity and duration of such dance provide a framework for planning the competitive season and developing strength and conditioning programs. This study examined the blood lactate (BL), heart rate (HR), and ratings of perceived exertion (RPE) of 14 well-trained female dancers on a competitive collegiate dance team. Subjects completed a treadmill test to determine their lactate threshold (LT) and then performed a 120-second choreographed jazz dance routine in cumulative 30-second segments, during which physiological markers were measured. All subjects exceeded their individually determined LT values by 90 seconds into the dance routine. A moderate (rs = 0.53; p < 0.001) positive correlation was observed between HR and RPE, as was a strong (rs = 0.70; p < 0.001) positive correlation between BL and RPE. Subjects worked at or above LT for much of the 120-second jazz dance routine, indicating that competitive collegiate dance is physiologically demanding and highly anaerobic. Understanding the physiological demands of competitive collegiate dance allows strength and conditioning professionals to develop, monitor, and adjust training parameters, which will aid in minimizing injury and maximizing competitive performance in collegiate dancers.
塞费特·冈萨雷斯，AM 和斯坦森，MC。竞技大学舞蹈的生理需求。J 力量与调节研究 38(9)：e503-e509，2024-竞技大学舞蹈结合了体操和杂技的元素，以及更传统的风格，如芭蕾舞、爵士舞和现代舞。评估这种舞蹈的生理需求并确定明确的强度和持续时间测量标准，为规划竞技赛季和制定力量和调节计划提供了框架。本研究检查了 14 名训练有素的女性竞技大学舞蹈队队员的血乳酸 (BL)、心率 (HR) 和感知用力等级 (RPE)。受试者进行了跑步机测试以确定他们的乳酸阈 (LT)，然后在 120 秒的累积 30 秒段中完成一段编排好的爵士舞蹈套路，在此期间测量生理指标。所有受试者在舞蹈套路进行到 90 秒时都超过了他们各自确定的 LT 值。HR 和 RPE 之间观察到中度正相关 (rs = 0.53；p < 0.001)，BL 和 RPE 之间观察到强正相关 (rs = 0.70；p < 0.001)。受试者在 120 秒的爵士舞蹈套路中大部分时间都在 LT 或以上工作，这表明竞技大学舞蹈在生理上要求很高，高度无氧。了解竞技大学舞蹈的生理需求使力量和调节专业人员能够开发、监测和调整训练参数，这将有助于减少受伤并最大限度地提高大学生舞者的竞技表现。
