Clinical Question:Are Nordic hamstring exercises more effective than standardized training in reducing hamstring strain injury rates in competitive soccer players over the course of at least one season?Clinical Bottom Line:The evidence supports the use of Nordic hamstring exercises to reduce hamstring injury incidence rates over a competitive soccer season. Therefore, progressive Nordic hamstring exercises should be included within some aspect of a practice to prevent the occurrence of hamstring injuries.
clinical Question: In a healthy adult population, which push-up position produces the greatest mean serratus anterior (SA) activation, expressed as a percentage of maximum voluntary isometric contraction (MVIC)? clinical Bottom line: In a healthy population, there is moderate evidence to support the use of the standard push-up on an unstable surface, elbow push-ups on stable and unstable surfaces, wall push-ups on an unstable surface, the full weight-bearing position using the Cuff Link system, and all three hand positions (shoulder width, wide base, and narrow base) with and without the use of the Perfect Pushup TM handgrips for the purpose of SA strengthening. These exercises produced a mean SA activation of at least 50% of the MVIC in the four cross-sectional studies that were reviewed for this critically appraised topic.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
