INTRODUCTION Eccentric exercise, where the contracting muscle is lengthened, produces microscopic damage in muscle fibers, and sensations of stiffness and soreness, the next day. These normally resolve within a week. A more major sports injury is the muscle strain. Because strain injuries are known to occur during eccentric contractions, it is hypothesized that the microscopic damage from eccentric exercise can, at times, progress to a muscle strain. As the amount of microscopic damage depends…

Is Muscle Architecture Different in Athletes with a Previous Hamstring Strain? A Systematic Review and Meta-Analysis

TLDR
Exercises that promote fascicle lengthening of both injured and uninjured leg muscles may be beneficial for athletes who recover from a hamstring injury.

Selective strength loss and decreased muscle activity in hamstring injury.

TLDR
Lengthened range assessment of isokinetic eccentric flexor torque may be useful for the assessment of athletes with a prior injury; however, results should be confirmed with prospective studies.

Eccentric training for hamstring injury, and its relationship to strength and flexibility: A case-series

TLDR
Support is added to the hypothesis that eccentric training can improve both strength and flexibility parameters among previously injured athletes, consistent with previous research among uninjured populations.

Rate of Torque and Electromyographic Development During Anticipated Eccentric Contraction Is Lower in Previously Strained Hamstrings

TLDR
Previously injured hamstrings displayed lower RTD and IMP during slow maximal eccentric contraction compared with the contralateral uninjured limb, and these findings could have important implications for hamstring strain injury and reinjury.

Hamstring strain injuries: recommendations for diagnosis, rehabilitation, and injury prevention.

TLDR
A clinical guide for the rehabilitation of acute hamstring injuries is proposed, including specific criteria for treatment progression and return to sport, and directions for future research are described, including injury-specific rehabilitation programs, objective measures to assess reinjury risk, and strategies to prevent injury occurrence.

Neuromuscular Factors Related to Hamstring Muscle Function, Performance and Injury

TLDR
The intra- and intermuscular coordination of the hamstrings appears to influence both hamstring muscle fatiguability and the risk of muscle strain injury, and careful exercise selection allows selective targeting of individual hamstring muscles or muscle segments and this seems to influence the pattern of chronic adaptations such as muscle hypertrophy.

Hamstring Injuries

TLDR
Pre-exercise stretching and adequate warm-up are important in the prevention of hamstring injuries and mobilisation is required in order to regain the original strength of the muscle and to achieve good final results in resorption of the connective tissue scar and re-capillarisation of the damaged area.

Hamstring injuries in sprinting - the role of eccentric exercise.

TLDR
A clinical approach utilizing an eccentric exercise regimen designed to strengthen the hamstrings in the late swing/early stance phase is outlined and a pilot study investigating the exercise indicates it is a valid method of preventing and rehabilitating the hamstring injury.

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.

Factors Associated with Hamstring Injuries

TLDR
A hamstring rehabilitation model is proposed that is based on the current understanding of the aetiological factors that contribute to hamstring muscle strain, and is not without limitations and speculations.

TLDR
Experimental muscle stretching protocols show significant stress relaxation and reduction of stiffness in muscle due to inherent viscoelastic properties of muscle rather than to reflex-mediated effects, which may be useful in understanding how muscle injury might be prevented.

Muscle damage from eccentric exercise: mechanism, mechanical signs, adaptation and clinical applications

TLDR
The ability of muscle to rapidly adapt following the damage from eccentric exercise raises the possibility of clinical applications of mild eccentric exercise, such as for protecting a muscle against more major injuries.

Isokinetic strength testing does not predict hamstring injury in Australian Rules footballers.

TLDR
Isokinetic muscle strength testing was not able to directly discriminate Australian Rules football players at risk for a hamstring injury.

Comparison of isokinetic strength and flexibility measures between hamstring injured and noninjured athletes.

TLDR
Analysis of variance indicated that the injured extremity was significantly less flexible than the noninjured extremity within the hamstring injured group, and the hamstringjured group was less flexible compared with the non-injured group.

Prophylaxis and management of hamstring muscle injuries in intercollegiate football players

TLDR
Isokinetic testing and rehabilita tion of muscle imbalances can prevent hamstring strains and stimulate it to heal with higher tensile strength during the critical healing period resulting in less like recurrences.

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.
