The aims of this study were to estimate the energy expenditure (EE) and the intensity of physical activity (PA) during a competitive simulation of Latin American dancing and to evaluate the differences in PA and EE values between the sexes, between different dance types, and between the various phases of the competition.
Ten Italian dancers (five couples, 5 males and 5 females) competing in Latin American dancing at the international level were examined in this study. The EE (kcal) was measured during the semifinal and final phases of the competition using the SenseWear Pro Armband (SWA). Paired-sample t-tests were used to determine differences in the metabolic equivalent (MET) and EE values between the semifinal and final phases and between each dance. One-way analysis of variance was used to analyze the differences in the MET and EE values between the sexes.
The intensity of PA during the dance sequence ranged from moderate (3 to 6 METs) to vigorous (6 to 9 METs). The male dancers had higher EE values than the female dancers during all phases of the simulation. Similar MET values were observed in both sexes. The PA intensity during the finals phase was vigorous for 56% of the time of dance. Of all the dance styles, the rumba had the lowest MET and EE values.
Our results demonstrate that competitive Latin American dancing is a heavy exercise and suggest that monitoring variables during normal training can improve training protocols and the dancers' fitness levels.
本研究的目的是估计拉丁舞竞技模拟过程中的能量消耗(EE)和身体活动强度(PA),并评估性别、不同舞蹈类型以及比赛各阶段之间PA和EE值的差异。
本研究对10名参加国际拉丁舞比赛的意大利舞者(5对,5名男性和5名女性)进行了检查。使用SenseWear Pro臂带(SWA)在比赛半决赛和决赛阶段测量EE(千卡)。配对样本t检验用于确定半决赛和决赛阶段以及各舞蹈之间代谢当量(MET)和EE值的差异。单因素方差分析用于分析性别之间MET和EE值的差异。
舞蹈过程中PA强度从中等(3至6 METs)到剧烈(6至9 METs)不等。在模拟的所有阶段,男性舞者的EE值均高于女性舞者。男女MET值相似。决赛阶段PA强度在舞蹈时间的56%为剧烈。在所有舞蹈风格中,伦巴的MET和EE值最低。
我们的结果表明,拉丁舞竞技是一项高强度运动,并表明在正常训练期间监测变量可以改善训练方案和舞者的体能水平。
