The purpose of this study is to highlight the evolution explosive strength in 4-year interval backs compartment and level adaptation game requirements. hypothesis that lower limbs rugby developed during past 4 years, trying keep up with higher needs first Romanian league. Explosive power was measured using ‘Just Jump System’, which a plyometric test mat on players conducted set three tests: squ...

Individuals jump higher when they adopt an external focus of attention, relative to an internal focus or no focus of attention (G. Wulf, T. Zachry, C. Granados, & J. S. Dufek, 2007). In the present study, the authors determined the underlying cause of this effect. Participants performed a vertical jump-and-reach task for (a) an external focus condition (i.e., participants focused on the rungs o...

BACKGROUND In certain diseases, functional constraints establish a greater relationship with muscle power than muscle strength. However, in hereditary peripheral polyneuropathies, no such relationship was found in the literature. OBJECTIVE In children with Charcot-Marie-Tooth (CMT), to identify the impact of muscle strength and range of movement on the static/dynamic balance and standing long...

Vertical drop jump has been suggested to be an effective movement screening task for ACL injury risk, but recent studies have questioned the ability of such tasks to accurately identify players with increased risk of injury. In this paper, we discuss the usefulness of movement screening tests from an injury prevention perspective.

Introduction Ankle joint taping is a common prophylactic measure used by individuals involved in sports. Little information is available on the effects of ankle joint taping on biomechanical parameters in subjects with FI during functional activities such as jump landing. [1] Thus the aim of this study was to examine the effects of ankle joint taping and exercise on ankle joint frontal and sagi...

Random walks are used to describe the trajectories of many motile animals and microorganisms. They are a useful tool for both qualitative and quantitative descriptions of the behaviour of such creatures. Simple diffusive random walk models, or position jump processes, are unrealistic as they allow for effectively infinite propagation and do not take into account correlation between steps. Othme...

Recent studies have focused on gender differences in movement patterns as risk factors for ACL injury. Understanding intrinsic and extrinsic factors which contribute to movement patterns is critical to ACL injury prevention efforts. Isometric lower-extremity muscular strength, anthropometrics, and jump-landing technique were analyzed for 2,753 cadets (1,046 female, 1,707 male) from the U.S. Air...
