Abstract:
This series of reviews focuses on the most important neuromuscularfunction in many sport performances, the ability to generate maximalmuscular power. Part 1 focuses on the factors that affect maximal powerproduction, while part 2, which will follow in a forthcoming edition ofSports Medicine, explores thepractical application of these findings by reviewing the scientificliterature relevant to the development of training programmes that-mosteffectively enhance maximal power production. The ability of theneuromuscular system to generate maximal power is affected by a rangeof interrelated factors. Maximal muscular power is defined and limitedby the force-velocity relationship and affected by the length-tensionrelationship. The ability to generate maximal power is influenced bythe type of muscle action involved and, in particular, the timeavailable to develop force, storage and utilization of elastic energy,interactions of contractile and elastic elements, potentiation ofcontractile and elastic filaments as well as stretch reflexes.Furthermore, maximal power production is influenced by morphologicalfactors including fibre type contribution to whole muscle area, musclearchitectural features and tendon properties as well as neural factorsincluding motor unit recruitment, firing frequency, synchronization andintermuscular coordination. In addition, acute changes in the muscleenvironment (i.e. alterations resulting from fatigue, changes inhormone milieu and muscle temperature) impact the ability to generatemaximal power. Resistance training has been shown to impact each ofthese neuromuscular factors in quite specific ways. Therefore, anunderstanding of the biological basis of maximal power production isessential for developing training programmes that effectively enhancemaximal power production in the human.
