Video analysis has become a useful tool in the preparation for sport performance and its use has highlighted the different physiological demands of seemingly similar sports and playing positions. The aim of the current study was to examine the performance differences between classical ballet and contemporary dance. In total 93 dance performances (48 ballet and 45 contemporary) were analysed for exercise intensity, changes in direction and specific discrete skills (e. g., jumps, lifts). Results revealed significant differences between the 2 dance forms for exercise intensity (p<0.001), changes in direction (p<0.001) and discrete skills (p<0.05) with gender differences noted in the latter (p<0.05). Ballet was characterised by longer periods at rest (38 s x min(-1)) and high to very high exercise intensities (9 s x min(-1)), whilst contemporary dance featured more continuous moderate exercise intensities (27 s x min(-1)). These differences have implications on the energy systems utilised during performance with ballet potentially stressing the anaerobic system more than contemporary dance. The observed high rates in the discrete skills in ballet (5 jumps x min(-1); 2 lifts x min(-1)) can cause local muscular damage, particularly in relatively weaker individuals. In conclusion, classical ballet and contemporary dance performances are as significantly different in the underlying physical demands placed on their performers as the artistic aspects of the choreography.
视频分析已成为运动表现准备的有用工具，其使用突出了看似相似的运动和比赛位置的不同生理需求。本研究的目的是检查古典芭蕾和现代舞的表现差异。总共分析了 93 个舞蹈表演（48 个芭蕾舞和 45 个现代舞），以评估运动强度、方向变化和特定离散技能（例如跳跃、提升）。结果表明，两种舞蹈形式在运动强度（p<0.001）、方向变化（p<0.001）和离散技能（p<0.05）方面存在显著差异，后者存在性别差异（p<0.05）。芭蕾舞的特点是休息时间更长（38 秒 x 分钟(-1)) 和高强度到非常高强度的运动强度（9 秒 x 分钟(-1))，而现代舞则以更连续的中等运动强度为特征（27 秒 x 分钟(-1))。这些差异对表演期间使用的能量系统有影响，芭蕾舞可能比现代舞更强调无氧系统。在芭蕾舞中观察到的离散技能的高频率（5 次跳跃 x 分钟(-1); 2 次提升 x 分钟(-1)) 可能会导致局部肌肉损伤，尤其是在相对较弱的个体中。总之，古典芭蕾和现代舞的表演在其表演者所承受的潜在物理需求方面与编舞的艺术方面有很大的不同。
