The purpose of this study was to determine the effect of postactivation potentiation (PAP)-inducing activities in 4 separate studies examining vertical (VJP) and horizontal (HJP) jump performance, shot put performance (SPP), and sprint performance (SP), in National Collegiate Athletic Association Division II athletes. Study 1: 12 male (mean ± SD; age = 20.2 ± 2.0 years; height = 178.1 ± 6.2 cm; weight = 73.3 ± 6.43 kg) and 8 female (age = 20.1 ± 1.0 years; height = 169.6 ± 5.5 cm; weight = 59.8 ± 7.6 kg) track athletes participated in HJP and VJP testing before and after performing a parallel back squat (PBS) at 85% 1 repetition maximum (RM). Study 2: 10 (6 men and 4 women) shot put throwers (age = 20.6 ± 0.7 years; height = 182.1 ± 9.8 cm; weight = 102.8 ± 23.6 kg) participated in SPP testing for control (C), 3RM bench press, and 3RM PBS protocols. Study 3: 7 football players (age = 20.4 ± 1.6 years; weight = 87.8 ± 8.3 kg; height = 184.3 ± 7.2 cm) participated in SP testing before (PBS1) and after (PBS2) performing a 3RM PBS. Study 4: 11 football players (age = 20.3 ± 1.8 years; height = 180.6 ± 7.5 cm; weight = 86.1 ± 12.8 kg) participated in VJP testing for C and 3RM PBS protocols. Results of study 1: There was a significant (p ≤ 0.05) increase in VJP (PRE = 61.9 ± 12.3 cm; POST = 63.6 ± 11.6 cm) and HJP (PRE = 93.7 ± 11.0 cm; POST = 95.9 ± 11.5 cm). Study 2: SPP after PBS (11.67 ± 1.92 m) was not different vs. C (11.77 ± 1.81), but bench press (11.91 ± 1.81 m) was significantly greater (p ≤ 0.05) than both PBS and C. Study 3: SP time was significantly lower for PBS2 (4.6014 ± 0.17995 seconds) vs. PB1 (4.6557 ± 0.19603 seconds). Study 4: There was no difference in VJP for C (68.35 ± 2.16 cm) vs. PBS (68.12 ± 2.51 cm). Our data show that a 3RM PBS resulted in significant improvements in VJP, HJP, SPP, and SP in National Collegiate Athletic Association Division II male and female athletes. Strength and conditioning practitioners should potentially alter their warm-up programs to include PAP protocols to enhance performance of power athletes. However, there were nonresponders in each study, and coaches and athletes need to determine whether it is worthwhile to identify nonresponders before implementing PAP protocols.
本研究的目的是在四项独立研究中,确定激活后增强效应(PAP)诱导活动对美国国家大学体育协会二级运动员垂直跳(VJP)、水平跳(HJP)、铅球成绩(SPP)和短跑成绩(SP)的影响。研究1:12名男性(平均±标准差;年龄 = 20.2±2.0岁;身高 = 178.1±6.2厘米;体重 = 73.3±6.43千克)和8名女性(年龄 = 20.1±1.0岁;身高 = 169.6±5.5厘米;体重 = 59.8±7.6千克)田径运动员在以85%的1次重复最大值(RM)进行平行后蹲(PBS)前后,参加了HJP和VJP测试。研究2:10名(6名男性和4名女性)铅球运动员(年龄 = 20.6±0.7岁;身高 = 182.1±9.8厘米;体重 = 102.8±23.6千克)参加了对照组(C)、3次重复最大值卧推和3次重复最大值PBS方案的SPP测试。研究3:7名足球运动员(年龄 = 20.4±1.6岁;体重 = 87.8±8.3千克;身高 = 184.3±7.2厘米)在进行3次重复最大值PBS之前(PBS1)和之后(PBS2)参加了SP测试。研究4:11名足球运动员(年龄 = 20.3±1.8岁;身高 = 180.6±7.5厘米;体重 = 86.1±12.8千克)参加了对照组(C)和3次重复最大值PBS方案的VJP测试。研究1的结果:VJP(测试前 = 61.9±12.3厘米;测试后 = 63.6±11.6厘米)和HJP(测试前 = 93.7±11.0厘米;测试后 = 95.9±11.5厘米)有显著(p≤0.05)提高。研究2:PBS后的SPP(11.67±1.92米)与对照组(11.77±1.81米)无差异,但卧推(11.91±1.81米)显著高于PBS和对照组(p≤0.05)。研究l3:PBS2的SP时间(4.6014±0.17995秒)显著低于PB1(4.6557±0.19603秒)。研究4:对照组(68.35±x 16厘米)和PBS组(68.12±2.51厘米)的VJP无差异。我们的数据表明,3次重复最大值PBS能显著提高美国国家大学体育协会二级男女运动员的VJP、HJP、SPP和SP。力量和体能训练从业者可能应改变他们的热身计划,纳入PAP方案,以提高力量型运动员的表现。然而,每项研究中都有未出现反应者(无提高的人),教练和运动员在实施PAP方案之前需要确定识别出未出现反应者是否值得。
