Kontou, EI, Berberidou, FT, Pilianidis, TC, Mantzouranis, NI, and Methenitis, SK. Acute effect of upper and lower body postactivation exercises on shot put performance. J Strength Cond Res 32(4): 970-982, 2018-The purpose of this study was to investigate the effect of different types of upper and lower' extremities exercises on acute increase of shot put performance, in moderate experienced throwers. Eight (n = 8) males and 9 (n = 9) female throwers participated in this study. Their bench press and squat maximum strength were measured while their shot put performance from power position was evaluated before and after 4 interventions: (a) plyometric push-ups (Plyo), (b) 6 s isometric push-ups (Iso), (c) 3 countermovement jumps (CMJs) and (d) 10 reps. of skipping (Skip). Interventions were performed in counterbalanced order with a 48-hour interval. Significant increase (p < 0.05) of shot put performances was observed after Plyo, Iso, and CMJ (range: 2.30 ± 1.82%-5.72 ± 4.32%). In addition, Iso induced the highest increase while Skip did not induce any improvement of throwing performance. The highest increases were recorded in men's performance after CMJ (5.72 ± 4.32%) while in women's performance after Iso (3.59 ± 2.7%). Javelin and discus throwers increase higher their performance after CMJs while shot putters after Iso. Significant correlations were found between training experience, maximum/relative strength, shot put performance and increase of throwing performance (%) after the interventions (r: 0.519-0.991, p < 0.05). Percentage increase of performance between Iso and Plyo have negative correlations (r: -0.569, p < 0.05) in contrast of those between Skip and CMJ (r: 0.710, p < 0.05). These results suggest that upper or lower body postactivation interventions may acutely increase the throwing performance. However, experience and strength are significant determinant of this increase.
孔托、EI、贝里贝里多、FT、皮利安尼季斯、TC、曼特扎尼斯、NI 和梅特尼蒂斯、SK。上、下身激活练习对推铅球成绩的急性影响。J 力量与调节研究 32(4):970-982，2018-本研究目的是探讨不同类型的上、下肢练习对上、下肢激活练习对中等经验铅球运动员急性铅球成绩提高的影响。8 名男性(n=8)和 9 名女性(n=9)运动员参加了这项研究。在进行 4 种干预措施之前和之后，测量了他们的卧推和深蹲最大力量，同时评估了他们从力量位置的铅球成绩：(a) 增强式俯卧撑(Plyo)，(b) 6 秒等长俯卧撑(Iso)，(c) 3 次反跳(C MJ)和(d) 10 次跳绳(Skip)。干预措施以 48 小时的间隔进行平衡交替。在 Plyo、Iso 和 CMJ 后，铅球成绩显著提高(p<0.05)(范围：2.30±1.82%-5.72±4.32%)。此外，Iso 引起的提高最高，而 Skip 则没有引起投掷成绩的任何提高。在男子成绩中，CMJ 后记录的提高最高(5.72±4.32%)，而在女子成绩中，Iso 后记录的提高最高(3.59±2.7%)。标枪和铁饼运动员在 CMJ 后提高成绩更高，而铅球运动员在 Iso 后提高成绩更高。干预后，训练经验、最大/相对力量、铅球成绩和投掷成绩提高百分比之间存在显著相关性(r:0.519-0.991，p<0.05)。与 Skip 和 CMJ 之间的相关性(r:0.710，p<0.05)相比，Iso 和 Plyo 之间的性能提高百分比的相关性为负(r:-0.569，p<0.05)。这些结果表明，上半身或下半身的激活后干预可能会急性增加投掷成绩。然而，经验和力量是提高的重要决定因素。
