The present study examines changes in muscle structure and neuromuscular performance induced by 15 weeks of power training with explosive muscle actions. Twenty‐three subjects, including 10 controls, volunteered for the study. Muscle biopsies were obtained from the gastrocnemius muscle before and after the training period, while maximal voluntary isometric contractions (MVC) and drop jump tests were performed once every fifth week. No statistically significant improvements in MVC of the knee…

Effect of plyometric training on neural and mechanical properties of the knee extensor muscles.
TLDR
Data suggest that the training regime probably induced mainly neural adaptations that were specifically related to the knee angle, and strength gains at 80° knee flexion likely contributed to the enhanced jump height in SJ and CMJ.
Stretch-shortening cycle exercises: an effective training paradigm to enhance power output of human single muscle fibers.
TLDR
In conclusion, short-term SSC exercise training enhanced single-fiber contraction performance via force and contraction velocity in type I, IIa, and IIa/IIx fibers.
Effects of plyometric and pneumatic explosive strength training on neuromuscular function and dynamic balance control in 60-70year old males.
Plyometric training improves voluntary activation and strength during isometric, concentric and eccentric contractions.
Effect of jumping interval training on neuromuscular and physiological parameters: a randomized controlled study.
TLDR
It is suggested that the JIT included in traditional endurance training induces moderate to large effects on neuromuscular and physiological parameters.
Muscle fiber composition, jumping performance and rate of force development adaptations induced by different power training volumes in females.
TLDR
The results suggest that relatively large eccentric power training volumes may result in detrimental neuromuscular adaptations, minimal changes in early RFD, and a reduction of type IIx muscle fiber percentage.
The effect of strength training, recreational soccer and running exercise on stretch-shortening cycle muscle performance during countermovement jumping.
Neuromuscular mechanics and hopping training in elderly
TLDR
It is shown that 11 W of hopping training improves the performance of physically active elderly men and is achieved with shorter GaM operating lengths and, therefore, increased fascicle stiffness and improved tendon utilization after training.
Influence of Preactivity and Eccentric Muscle Activity on Concentric Performance during Vertical Jumping
TLDR
The data from this investigation indicate that a significant increase in concentric vertical jump performance is associated with increased levels of preactivity and eccentric phase muscle activity (SJ to CMJ), however, higher eccentric loading (CMJ to DJ) leads to a negative energy balance during the eccentric phase, which may relate to a non-significant increase in vertical jump height, even with coincidental increases in peak concentric force.
Muscle Fiber and Performance Changes after Fast Eccentric Complex Training
TLDR
A combination of low-volume fast eccentric and ballistic jump squat training with plyometric jumps in a strength–power potentiation complex format induced substantial increases in peak leg muscle power, RFD, and maximal strength, accompanied by gains in CSA of all muscle fiber types, without a reduction in fast twitch fiber composition.

Changes in neuromuscular performance in voluntary and reflex contraction during strength training in man.
TLDR
The interrelationship between the changes in EMG/force ratios of the reflex and voluntary contractions suggests that the mechanical response of individual muscle fibers of the respective motor units has improved.
Effect of explosive type strength training on isometric force- and relaxation-time, electromyographic and muscle fibre characteristics of leg extensor muscles.
TLDR
It can be concluded that in training for fast force production considerable neural and selective muscular adaptations may occur to explain the improvement in performance, but that genetic factors may determine the ultimate potential of the trainability of this aspect of the neuromuscular performance.
Mixed-methods resistance training increases power and strength of young and older men.
TLDR
Although the results of this study confirm age-related reductions in muscle strength and power, the older men did demonstrate similar capacity to young men for increases in these variables via an appropriate periodized resistance-training program that includes rapid, high-power exercises.
Neuromuscular adaptations and serum hormones in females during prolonged power training.
TLDR
The present results in female subjects indicate the important role of training-induced adaptations in the nervous system for muscular power development during prolonged training and an important indicator of the trainability of an individual.
The Effect of Heavy‐ Vs. Light‐Load Jump Squats on the Development of Strength, Power, and Speed
TLDR
This investigation indicates that training with light-load jump squats results in increased movement velocity capabilities and that velocity-specific changes in muscle activity may play a key role in this adaptation.
Interrelationships between muscle structure, muscle strength, and running economy.
TLDR
Differences in RE among homogeneous group of middle-distance runners were observed at various running speeds, and may partly be explained by differences in muscle fiber distribution, MHC composition, and titin isoforms.
Muscle hypertrophy and fast fiber type conversions in heavy resistance-trained women
TLDR
The heavy-resistance training resulted in significant hypertrophy of all three groups: I (15%), IIA (45%), and IIAB + IIB (57%).
Moment and power of lower limb joints in running.
TLDR
The results may suggest that the role of the ankle and knee extensor is to create high joint stiffness before and during the contact phase, while the hip extensors are the prime forward movers of the body with increasing running speed.
Effect of Explosive Resistance Training on Titin and Myosin Heavy Chain Isoforms in Trained Subjects
TLDR
The data from this investigation indicates that a relatively short period of explosive resistance training results in negligible changes in the expression of MyHC or titin isoforms.
