This study compared sex responses for strength and barbell velocity from very short-term resistance training (VST, consisting of 2-3 training sessions) for an upper body dynamic constant external resistance (DCER) exercise (bench press [BP]). Ten females (mean ± standard deviation (SD) age: 21.3 ± 3 years, height: 166.2 ± 6 cm, body mass: 71.4 ± 10.7 kg) and 10 males (mean ± SD age: 24.6 ± 4 years, height: 179.5 ± 8 cm, body mass: 88.6 ± 11 kg) completed a pre-test visit to determine the BP 1 repetition maximum (1RM) as well as the mean (BP) and peak (BP) barbell velocities from the BP 1RM. The VST involved three training visits where the participants performed 5 sets of 6 repetitions, at 65% of the 1RM. The post-test followed the same procedures as the pre-test visit. There were significant increases in 1RM strength for both the males (5.1%) and females (5.4%) between pre-test and post-test. There were no significance differences between sex for mean (BP) and peak (BP); however, overall there was a 32.7% increase in BP and a 29.8% increase in BP. These findings indicated an increase in strength and barbell velocity for both males and females as a result of VST upper body DCER exercise in untrained subjects.
本研究比较了非常短期阻力训练（VST，由2 - 3次训练课组成）对上肢动态恒定外部阻力（DCER）练习（卧推[BP]）的力量和杠铃速度的性别反应。10名女性（平均±标准差（SD）年龄：21.3±3岁，身高：166.2±6厘米，体重：71.4±10.7千克）和10名男性（平均±SD年龄：24.6±4岁，身高：179.5±8厘米，体重：88.6±11千克）完成了一次预测试访，以确定卧推1次重复最大值（1RM）以及卧推1RM时的平均（BP）和峰值（BP）杠铃速度。VST包括三次训练访，参与者以1RM的65%进行5组，每组6次重复。后测试遵循与预测试访相同的程序。在预测试和后测试之间，男性（5.1%）和女性（5.4%）的1RM力量均有显著增加。平均（BP）和峰值（BP）在性别之间没有显著差异；然而，总体而言，BP增加了32.7%，BP增加了29.8%。这些发现表明，未经训练的受试者通过VST上肢DCER练习，男性和女性的力量和杠铃速度均有所增加。
