Eccentric resistance training has been shown to elicit beneficial effects on performance and injury prevention in sports because of its specific muscular and neural adaptations. Within the different methods used to generate eccentric overload, flywheel eccentric training has gained interest in recent years because of its advantages over other methods such as its portability, the ample exercise variety it allows and its accommodated resistance. Only a limited number of studies that use flywheel devices provide enough evidence to support the presence of eccentric overload. There is limited guidance on the practical implementation of flywheel eccentric training in the current literature. In this article, we provide literature to support the use of flywheel eccentric training and present practical guidelines to develop exercises that allow eccentric overload.
The purpose of this article is to present the reader with the prescription of a daily specific stretching routine that can help athletes avoid the onset of injuries and chronic pain in muscle-tendon structures of the lower extremities.
This article provides a proposed holistic solution to increase functional, quality movement among Marines, thereby increasing physical performance, reducing injuries, and developing more effective warfighters.
This article provides strength and conditioning coaches with strategies to address hip mobility limitations that may lead to lumbar spine and femoral acetabular issues.
Older adults who desire to remain physically active at work, recreation, or sport can improve muscular strength, physical performance, and injury prevention if engaged in a properly designed resistance exercise program. The programming considerations presented herein may serve as a useful reference for strength and conditioning professionals working closely with active older adults.
Despite an incidence of approximately 3.8 million sports-related concussions per year, prevention of this injury remains quite challenging. Neck strengthening may limit transmitted forces to the head and mitigate trauma to the brain. In this session from the 2015 NSCA Coaches Conference, Tad Seifert reviews current evidence-based data in neck strength and its association with concussions.
