摘要

核心强化训练已被纳入各级运动员的体能训练方案。尽管有大量的证据,核心稳定性训练对跳远成绩有什么影响的问题仍然没有解决。只有一小部分研究探讨了独立核心训练的效果。本研究旨在探讨活化后增强(PAP)对大鼠逆动作跳跃(CMJ)表现的急性改变。招募了25名男性休闲运动员作为研究对象。他们进行了三次访问-首先是熟悉,随后是使用常规热身获得基线数据,最后是在诱导PAP时重复数据。等距测功仪用于量化岩心的等距强度,CMJ变量使用MARS软件的便携式性能分析系统进行评估。进行配对t检验和多变量分析。从常规热身到PAP热身,所有核心力量指标均显著增加,P<0.001。以下CMJ指标差异显著:起跳高度(P<0.001)、飞行高度(P<0.01)、飞行时间(P<0.01)和自由落体力(P<0.001)。PAP核心训练是一种神经肌肉训练形式,通过改变力量吸收、主动关节稳定和改善运动模式,有可能提高力量、敏捷性和速度。这些变化归因于大脑驱动的变化,以及肌肉水平上运动单元激活和放电频率的增强。在比赛前,核心激活热身可以提供独特的训练刺激,并通过人体机能反应提高表现。核心肌群对最佳运动表现至关重要,不应被忽视。

Effect of post-activation potentiation using core activation on isometric core strength and countermovement jump variables in university male recreational athletes
Core strengthening exercises have been integrated into the conditioning regimens of sportsmen of all levels. Despite a wealth of evidence, the question of what influence core stability exercises have on jump performance remains unsolved. Only a small percentage of studies have explored effects of standalone core training. The objective of this research was to explore acute changes in countermovement jump (CMJ) performance caused by post-activation potentiation (PAP) adopting core activation exercises. 25 male recreational athletes were recruited as participants. They visited on three occasions-first for familiarisation, following for baseline data using a conventional warmup, and final for repeat data upon inducing PAP. Isometric dynamometer was used to quantify core isometric strength and CMJ variables were evaluated using a Portable performance analysis system with MARS Software. Paired t-test and multivariate analysis were carried out. All core strength metrics reported marked increase at P<0.001 from conventional to PAP warmup. Following CMJ metrics varied significantly: jump height from take-off (P<0.001), jump height from flight (P<0.01), flight time (P<0.01,) and force at free-fall (P<0.001). Core training with PAP is a form of neuromuscular training that has the potential to improve power, agility, and speed by modifying force absorption, active joint stabilisation, and improved movement patterns. These alterations are ascribed to changes in cerebral drive, as well as enhanced motor-unit activation and firing frequency at the muscle level. Before a competition, a core activation warm-up can offer a unique training stimulus and increase performance via an ergogenic response. The core is essential for optimal athletic performance and should not be overlooked.

期刊介绍: ''Comparative Exercise Physiology'' is the only international peer-reviewed scientific journal specifically dealing with the latest research in exercise physiology across all animal species, including humans. The major objective of the journal is to use this comparative approach to better understand the physiological, nutritional, and biochemical parameters that determine levels of performance and athletic achievement. Core subjects include exercise physiology, biomechanics, gait (including the effect of riders in equestrian sport), nutrition and biochemistry, injury and rehabilitation, psychology and behaviour, and breeding and genetics. This comparative and integrative approach to exercise science ultimately highlights the similarities as well as the differences between humans, horses, dogs, and other athletic or non-athletic species during exercise. The result is a unique forum for new information that serves as a resource for all who want to understand the physiological challenges with exercise.
