Power Training Methods Across the Load–Velocity Continuum: Mechanisms, Applications, and Periodization

Muscular power is a critical determinant of athletic performance. Despite the wide range of resistance training methods proposed to enhance power, uncertainty remains regarding their physiological rationale, practical applications, and optimal integration within long-term training programs. This narrative review synthesizes current evidence on the principal resistance training methods for muscular power development and provides an evidence-informed framework for exercise selection and periodized programming. A structured literature search was conducted using PubMed, SPORTDiscus, and Scopus, complemented by additional sources and reference screening. Seventeen studies were retained for the evidence mapping, while systematic reviews, meta-analyses, position stands, and narrative reviews were used to provide conceptual background and contextual interpretation. No formal study-level methodological quality appraisal was performed; therefore, the findings were interpreted as an evidence-informed narrative synthesis rather than an evidence-graded assessment of training-method effectiveness. Current evidence indicates that different resistance training methods target specific regions of the load–velocity continuum through distinct neuromuscular adaptations. Heavy resistance training primarily enhances maximal force production, whereas ballistic training, Olympic weightlifting derivatives, velocity-based training, optimal power load, cluster sets, variable resistance, isometric training, eccentric overload, complex-contrast training, and triphasic training provide complementary stimuli for optimizing muscular power through different approaches. Overall, the evidence supports integrating complementary resistance training methods within a periodized program tailored to the athlete’s training status, sport-specific demands, and competitive calendar to maximize power development.
