García-Ramos, A, Haff, GG, Jiménez-Reyes, and P, Pérez-Castilla, A. Assessment of upper-body ballistic performance through the bench press throw exercise: Which velocity outcome provides the highest reliability? J Strength Cond Res 32(10): 2701-2707, 2018-This study aimed to compare the between-session reliability of 3 velocity variables (mean velocity [MV], mean propulsive velocity [MPV], and maximum velocity [Vmax]) to assess bench press throw (BPT) performance. Twenty-one men were tested during 2 consecutive weeks in 2 variants of the BPT exercise (concentric-only and eccentric-concentric) against 5 different loading conditions (17, 27, 37, 47, and 57 kg). The 2 sessions of each BPT variant were performed within the same week separated by 48-72 hours. The main findings revealed that (a) the highest reliability was observed for Vmax (median coefficient of variation [CV] and range) (CV = 2.14% [1.43-4.02%]), followed by MV (CV = 3.18% [1.47-5.22%]), and finally, the MPV was the least reliable variable (CV = 4.27% [1.98-6.38%]), (b) all velocity variables demonstrated a higher reliability during the eccentric-concentric BPT (CV = 2.41% [1.43-5.30%]) when compared with the concentric-only BPT (CV = 4.02% [1.74-6.38%]), and (c) the reliability tended to decrease with the increment of the load: 17 kg (CV = 2.12% [1.43-4.68%]), 27 kg (CV = 1.96% [1.74-3.86%]), 37 kg (CV = 2.98% [2.47-5.67%]), 47 kg (CV = 4.59% [2.32-6.38%]), and 57 kg (CV = 3.92% [1.95-5.52%]). These results indicate that the assessment of the Vmax should be performed with a light-loading condition during the eccentric-concentric BPT for obtaining the most reproducible measure of upper-body ballistic performance.
加西亚 - 拉莫斯，A，哈夫，GG，希门尼斯 - 雷耶斯，和 P，佩雷斯 - 卡斯蒂利亚，A. 通过卧推投掷练习评估上半身弹道性能：哪种速度结果提供最高的可靠性？ J 力量和调节研究 32(10)：2701-2707，2018-本研究旨在比较 3 种速度变量（平均速度[MV]，平均推进速度[MPV]和最大速度[Vmax]）的两次测试之间的可靠性，以评估卧推投掷（BPT）性能。21 名男性在 2 周内的 2 种 BPT 变体（仅向心和向心 - 离心）中进行了测试，共进行了 5 种不同的加载条件（17、27、37、47 和 57 千克）。每个 BPT 变体的 2 个会话在同一周内进行，间隔 48-72 小时。主要发现表明：（a）Vmax（中值变异系数[CV]和范围）（CV = 2.14%[1.43-4.02%]）观察到最高可靠性，其次是 MV（CV = 3.18%[1.47-5.22%]），最后是 MPV 是最不可靠的变量（CV = 4.27%[1.98-6.38%]），（b）当与仅向心 BPT（CV = 4.02%[1.74-6.38%]）相比时，所有速度变量在向心 - 离心 BPT 中显示出更高的可靠性（CV = 2.41%[1.43-5.30%]），（c）随着负荷的增加，可靠性趋于下降：17 千克（CV = 2.12%[1.43-4.68%]），27 千克（CV = 1.96%[1.74-3.86%]），37 千克（CV = 2.98%[2.47-5.67%]），47 千克（CV = 4.59%[2.32-6.38%]）和 57 千克（CV = 3.92%[1.95-5.52%]）。这些结果表明，在向心 - 离心 BPT 中应使用轻负荷条件来评估 Vmax，以获得最可重复的上半身弹道性能测量值。
