This study compared the effectiveness of the single-leg Roman chair hold exercise with the Nordic hamstring curl exercise in athletes with previous hamstring injuries.

The purpose of this article is to describe the cause of hamstring injuries in sprinters and present a biomechanical intervention, or drill, that can be used to prevent hamstring injuries while transitioning sprint athletes toward the utilization of frontside mechanics.

This article provides a review of the anatomy of the hamstring muscles and includes ways to minimize the severity and frequency of hamstring strains.

According to a recent study, the hip hinge kettlebell swing produced the greatest amount of hamstring surface electromyography of the three styles of kettlebell swings that were assessed. These findings have implications for the application of kettlebell swing exercises in strength and conditioning, injury prevention, and rehabilitation programs.

NSCA Coach 11.4 shares how strength training of the posterior chain in athletes can reduce injury risk and aid rehabilitation. Visit us online to read more about exercise research.

The purpose of this article is to present a sample injury prevention program with a specific emphasis on lower body posterior chain development throughout competitive and non-competitive college lacrosse seasons.

This article highlights the scientific evidence on exercises like the seated leg extension, leg curl, and adduction machines to highlight their potential benefits on enhanced performance and potentially reducing injury risk.

This infographic gives insight into the effects on performance from static and dynamic stretching of the hamstring muscles.

The purpose of this article is to provide personal trainers with a review of common muscle extensibility tests of the lower extremity.

Considering the great popularity of eccentric-based training, the purpose of this review is to first provide the scientific rationale for its use; second, summarize the eccentric-based training modalities that can be used; and finally, offer practical recommendations on how to implement eccentricbased modalities to enhance sports performance. The molecular and neural mechanisms underlying eccentric actions are partially distinct from those of concentric and isometric actions. During eccentric actions, theories suggest a strain-induced modulation of actin-myosin interactions at the crossbridge level, activation of structural protein titin, and winding of titin on actin. Eccentric acute physiological responses differ from concentric exercise responses, including variations in neuromuscular, metabolic, hormonal, and anabolic signaling. Eccentric training elicits greater improvements in muscle strength, power, and stretch-shortening cycle function compared with concentric-only or traditional resistance training. Therefore, eccentric-based training can lead to unique neuromuscular (e.g., improved coordination of motor units) and morphological (e.g., increased muscle fascicle length and enhanced distal cross-sectional area) adaptations that could play a key role in sport performance. Practitioners may implement eccentric exercises with external loads, fully eccentric-based exercises (e.g., Nordic hamstring curl), accentuated eccentric loading, flywheel resistance exercise, and plyometrics to develop specific physical adaptations in line with their goals. Eccentric work (e.g., for hamstrings) can be obtained during other exercises such as downhill running tasks, decelerations, and sprinting activities. Practitioners need to be aware that no single “silver bullet” training modality exists; consequently, practitioners should use a combination of eccentric-based training approaches with their athletes to obtain the desired adaptations.
