Abstract

ABSTRACT Introduction: Submaximal strength testing appears to be valid to prescribe the intensity for strength training protocols that reduce the risk of injuries and testing time. Objective: This study aimed to assess the predictive ability of body mass parameters to estimate 4-6 repetitions maximum (4-6 RM) of Leg press 45°, Chest press, and Pull-down exercises. Methods: Eleven male bodybuilders (age 38.27 ± 10.48 years) participated in this study. Participants completed an incremental external load up to find the load allowing them to perform 4 to 6 maximal repetitions for each exercise in random order. The starting load was 50% of body mass for chest press and pull-down exercises and 100% for leg press. The load increment after each set was 20 kg for lower limb exercises and 10 kg for upper body exercises. Results: Results revealed that body mass had good to optimal relationships with 4-6 RM for all three exercises. Results showed that body mass had a good prediction ability for all three criterion measures. Conclusion: The prediction equations suggested in this study may allow coaches to estimate the 4-6 RM of leg press 45°, chest press, and pull-down performances. Evidence Level IV; Case series.

身体质量预测4-6米的胸肌和腿部肌肉锻炼的健美运动员

摘要简介:亚最大力量测试似乎是有效的规定强度的力量训练方案，减少受伤的风险和测试时间。目的:本研究旨在评估体重参数对45°腿压、胸压和下拉练习4-6次最大重复(4-6 RM)的预测能力。方法:11例男性健美运动员，年龄38.27±10.48岁。参与者完成了一个增量的外部负荷，以找到允许他们在随机顺序的每次锻炼中进行4到6次最大重复的负荷。开始负荷为体重的50%用于胸部按压和下拉练习，100%用于腿部按压。每组后负荷增量为下肢20 kg，上肢10 kg。结果:结果显示，在所有三种运动中，体重与4-6 RM有良好的最佳关系。结果表明，体重对三项指标均有较好的预测能力。结论:本研究提出的预测方程可以让教练估计45°腿压、胸压和下拉动作的4-6 RM。证据等级IV;病例系列。

期刊介绍： The Revista Brasileira de Medicina do Esporte (RBME in its Portuguese form) is an official organ of the Sociedade Brasileira de Medicina do Exercício e do Esporte (SBME) Brazilian Society of Exercise Medicine and Sports) and represents the main promotion resource of the scientific production in the Exercise Sciences and Sports Medicine (SBME) fields in our country. The RBME was launched in 1995 with trimester periodicity and became regularly bi-monthly published with no interruptions from 1999. RBME is an inter-and multidisciplinary, peer reviewed, Open Access journal which accepts contributions from the national and international scientific community. RBME publishes original articles of high scientific relevance in Exercise and Sports Medicine, review articles, and systematic reviews. RBME preferably publishes original articles of international interest, not only of regional significance. Its goal is to disseminate the scientific production in the areas of exercise and sports medicine through the publication of original research results and other documents that contribute to the scientific and applied knowlewdge of physical activity, exercise and sports, within the framework of biological sciences and medicina. Its title abbreviation is Rev Bras Med Esporte, which should be used in references, footnotes and reference subtitles.
