Physical demands vary among dance styles, and injury patterns differ accordingly. Modern dance tends to be high in upper-body demands, and university-level female modern dancers are suggested to be at high risk for upper-body injury. Low muscular endurance is a known injury risk factor. Whether modern dancers have different upper-body muscular endurance than non-dancers is unclear. Thus, the purpose of this study was to compare upper-body endurance in female university-level modern dancers (n = 17) and physically active non-dancers (n = 15), using the modified push-up test. Pearson-correlations examined relationships between anthropometrics and push-ups. Multiple regression analyses were used to determine whether anthropometrics and physical activity could predict push-up scores. One-way ANOVAs compared upper-body endurance (number of push-ups) and physical activity between groups (p < 0.05). Except for height (r = -.37), no variables were related to push-ups. Neither anthropometrics nor physical activity were able to predict push-up scores (p = 0.25). Despite dancers being more active/day (3.6 ± 1.9 vs. 0.9 ± 0.4 hrs/day, p < 0.001), more times per week (5.4 ± 1.2 vs. 4.0 ± 1.8, p = 0.02), and having greater overall physical activity volumes (20.4 ± 11.4 vs. 3.3 ± 2.5 hrs/week, p < 0.001) than non-dancers, both groups had similar upper-body endurance (22.2 ± 8.6 vs. 19.9 ± 8.2, p = 0.44). A probable explanation for this similarity exists in the lack of physical activity beyond dance itself performed by the dancers; our preliminary work suggests that modern dance alone may not produce upper-body muscle endurance gains. Hence, it is suggested that modern dancers should engage in strength and conditioning training programs to enhance upper-body endurance.
不同舞蹈风格对身体的要求各异，受伤模式也相应不同。现代舞对上半身的要求往往较高，大学水平的女性现代舞者被认为上半身受伤风险较高。肌肉耐力低是已知的受伤风险因素。目前尚不清楚现代舞者的上半身肌肉耐力是否与非舞者不同。因此，本研究的目的是使用改良俯卧撑测试比较大学水平的女性现代舞者（n = 17）和有体育活动习惯的非舞者（n = 15）的上半身耐力。采用皮尔逊相关性分析检验人体测量学指标与俯卧撑之间的关系。多元回归分析用于确定人体测量学指标和体育活动是否能够预测俯卧撑得分。单因素方差分析比较两组之间的上半身耐力（俯卧撑次数）和体育活动情况（p < 0.05）。除身高（r = -0.37）外，没有其他变量与俯卧撑相关。人体测量学指标和体育活动均无法预测俯卧撑得分（p = 0.25）。尽管舞者每天的活动量更大（3.6 ± 1.9小时/天 vs. 0.9 ± 0.4小时/天，p < 0.001），每周活动次数更多（5.4 ± 1.2次 vs. 4.0 ± 1.8次，p = 0.02），且总体体育活动量更大（20.4 ± 11.4小时/周 vs. 3.3 ± 2.5小时/周，p < 0.001），但两组的上半身耐力相似（22.2 ± 8.6次 vs. 19.9 ± 8.2次，p = 0.44）。这种相似性的一个可能解释是舞者除了舞蹈本身之外缺乏其他体育活动；我们的初步研究表明，仅现代舞可能无法提高上半身肌肉耐力。因此，建议现代舞者应参加力量和体能训练计划以增强上半身耐力。
