HOW SKELETAL MUSCLES ADAPT to a repeated stimulus depends, to a large extent, on the neuromuscular recruitment of muscle fibers as well as on the inherent characteristics of the muscles themselves. The specific types of fibers that make up individual muscles greatly influence the way your clients will adapt to their training programs. There is a reason why some people get bigger muscles more easily than others and why some people are able to run for much longer periods of time without fatigue…

Emphasizing Task-Specific Hypertrophy to Enhance Sequential Strength and Power Performance
TLDR
Different types ofhypertrophy are addressed and 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 are provided.
The Effects of Endurance, Strength, and Power Training on Muscle Fiber Type Shifting
TLDR
The purpose of this article is to analyze the effects of various forms of exercise on type I and type II interconversions, and possible variables that may increase type II fibers and decrease type I fibers are discussed.
Prediction of muscle fiber composition using multiple repetition testing
TLDR
The number of completed repetitions at 80% of 1RM is moderately correlated with muscle fiber composition, and the percentage of fast-twitch fibers from vastus lateralis was investigated.
Evaluation of Lower-Limb Rehabilitation Based on Muscle Fatigue
TLDR
The increase in the time at the beginning and the end of the training period indicates the improvement of motor function, and thus it verifies the effectiveness of the rehabilitation.
Surface Electromyography Based Analysis of Muscle Fiber Type Proportions
TLDR
The features of sEMG features such as root mean square, peak frequency and entropy are found to be useful in analysing muscle fiber type proportion and shows variation with muscle fiber types.
Characteristics of the Electrophysiological Properties of Neuromuscular Motor Units and Its Adaptive Strategy Response in Lower Extremity Muscles for Seniors with Pre-Sarcopenia: A Preliminary Study
TLDR
Some neuromuscular characters between sarcopenia and healthy elderly and young people when performing the same level of leg exercise tasks may provide some hints for discovering aging-related strength and function loss.
Human Muscle Fatigue Model in Dynamic Motions
TLDR
Each human joint is assumed to be controlled by two muscle groups to generate motions such as push/pull and the evaluation of this model can predict the fatigue and MSD risk in industry production quickly.
Relation of submaximal concentric exercise to muscle fiber composition and substrate utilization in type 2 diabetic, obese and healthy men
TLDR
The relationship between force production, muscle fibre type distribution and substrate utilization at rest and during exercise, and type IIAB, MHCIIx and force production bore a close relationship to the incidence of T2DM/obesity.
Fiber Type Composition and Capillary Density in Relation to Submaximal Number of Repetitions in Resistance Exercise
TLDR
The results suggest that fiber type composition is not the major biological variable regulating the number of repetitions performed in submaximal resistance exercise, and it seems that sub maximal strength performance depends on muscle capillary density, which is linked with the endurance capacity of the muscle tissue.
Effects of Dynamic and Static Stretching on Vertical Jump Performance and Electromyographic Activity
TLDR
Some physiological basis is provided for the inclusion of DS and exclusion of SS in preparation for activities requiring jumping performance, and SS has a negative influence on VJ performance, whereas DS has a positive impact.

Adaptive response in human skeletal muscle subjected to prolonged eccentric training.
TLDR
It is concluded that skeletal musculature adapts itself in a functional manner to the extreme tension demands put on them and improved coordination and reorganization of the contractile apparatus of muscle fibers are the determining mechanisms.
Muscle Mechanics: Adaptations with Exercise‐Training
TLDR
A positive correlation exists between the percentage of fast fibers and peak torque output at moderate-to-high angular isokinetic velocities and, consequently, peak power output is substantially greater in subjects possessing a predominance of fast fiber types.
Influence of eccentric actions on skeletal muscle adaptations to resistance training.
TLDR
Three different training regimens were performed to study the influence of eccentric muscle actions on skeletal muscle adaptive responses to heavy resistance exercise, and changes in fibre type composition and capillary frequency were manifest after detraining.
Exercise-Induced Muscle Damage and Potential Mechanisms for the Repeated Bout Effect
TLDR
There is little consensus as to the actual mechanism of the repeated bout effect, but it is possible that the phenomenon occurs through the interaction of various neural, connective tissue and cellular factors that are dependent on the particulars of the eccentric exercise bout and the specific muscle groups involved.
Decline running produces more sarcomeres in rat vastus intermedius muscle fibers than does incline running.
TLDR
A clear and repeatable difference was found, supporting Morgan's prediction of more sarcomeres after decline running, although with some differences in response that depended on the age of the rats.
Acute and Chronic Response of Skeletal Muscle to Resistance Exercise
SummarySkeletal muscle tissue is sensitive to the acute and chronic stresses associated with resistance training. These responses are influenced by the structure of resistance activity (i.e.
Human hamstring muscles adapt to eccentric exercise by changing optimum length.
TLDR
This is the first study to show a sustained shift in optimum angle of human muscle as a protective strategy against injury from eccentric exercise, and implications for athletes, particularly those prone to hamstring strains are discussed.
Damage to human muscle from eccentric exercise after training with concentric exercise
TLDR
It is concluded that a period of concentric exercise increases the susceptibility of muscle to changes associated with the damage from eccentric exercise.
Large-fiber mechanoreceptors contribute to muscle soreness after eccentric exercise.
TLDR
It is concluded that muscle mechanoreceptors, including muscle spindles, contribute to the soreness after eccentric exercise.
