While strength is indeed a skill, most discussions have primarily considered structural adaptations rather than ultrastructural augmentation to improve performance. Altering the structural component of the muscle is often the aim of hypertrophic training, yet not all hypertrophy is equal; such alterations are dependent upon how the muscle adapts to the training stimuli and overall training stress. When comparing bodybuilders to strength and power athletes such as powerlifters, weightlifters, and throwers, while muscle size may be similar, the ability to produce force and power is often inequivalent. Thus, performance differences go beyond structural changes and may be due to the muscle's ultrastructural constituents and training induced adaptations. Relative to potentiating strength and power performances, eliciting specific ultrastructural changes should be a variable of interest during hypertrophic training phases. By focusing on task-specific hypertrophy, it may be possible to achieve an optimal amount of hypertrophy while deemphasizing metabolic and aerobic components that are often associated with high-volume training. Therefore, the purpose of this article is to briefly address different types of hypertrophy and provide directions for practitioners who are aiming to achieve optimal rather than maximal hypertrophy, as it relates to altering ultrastructural muscular components, to potentiate strength and power performance.
虽然力量确实是一项技能,但大多数讨论主要考虑的是结构适应性,而非超微结构增强以提高运动表现。改变肌肉的结构成分通常是肥大训练的目标,但并非所有肥大都是相同的;这种改变取决于肌肉如何适应训练刺激和整体训练压力。将健美运动员与力量和爆发力运动员(如力量举运动员、举重运动员和投掷运动员)进行比较时,虽然肌肉大小可能相似,但产生力量和爆发力的能力往往并不等同。因此,运动表现的差异不仅仅在于结构变化,还可能归因于肌肉的超微结构成分和训练引起的适应性变化。相对于增强力量和爆发力表现而言,引发特定的超微结构变化应该是肥大训练阶段一个值得关注的变量。通过专注于特定任务的肥大,有可能在减少通常与高容量训练相关的代谢和有氧成分的同时,实现最佳的肥大效果。因此,本文的目的是简要探讨不同类型的肥大,并为旨在实现最佳而非最大肥大效果的从业者提供指导,因为这与改变肌肉超微结构成分、增强力量和爆发力表现有关。
