OBJECTIVES To date, few rigorous scientific studies have been conducted to understand the impact mechanics and muscle activation characteristics of different landing tasks and the influence of shoe properties. The aim of this study was to examine the effects of shoe cushioning on impact biomechanics and muscular responses during drop landings. DESIGN A single-blinded and randomized design. ...

The purpose of this study was to examine the effects of a comprehensive neuromuscular training program on measures of performance and lower-extremity movement biomechanics in female athletes. The hypothesis was that significant improvements in measures of performance would be demonstrated concomitant with improved biomechanical measures related to anterior cruciate ligament injury risk. Forty-o...

Due to the relative infancy of Parkour there is currently a lack of empirical evidence on which to base specific technique instruction upon. The purpose of this study was to compare the ground reaction forces and loading rates involved in two Parkour landing techniques encouraged by local Parkour instructors and a traditional landing technique recommended in the literature. Ten male participant...

Landing of an UAV is a most complicated and important operation for autonomous flight operations. Most of the UAVs are operate with external pilots. Nowadays it is essential to design the advance automatic landing control systems to reduce the work load of external pilots in the landing process of UAVs. In this paper various auto rectification landing systems using fuzzy logic has studied and d...

Human performance training and prevention strategies are necessary to promote physical readiness and mitigate musculoskeletal injuries of the Naval Special Warfare (NSW) Operator. The purpose of this study was to measure the effectiveness of 2 training programs when performed during a training evolution of Operators. A total of 85 Operators (experimental: n = 46, age: 29.4 ± 5.5 years, height: ...

Accurate representation of soft tissue material properties plays a crucial role in computational biomechanics. Several models have been used for knee ligaments finite element (FE) studies, including the neo-Hookean model (widely used) and Holzapfel-Gasser-Ogden (HGO) (seldom used). While coefficients are available literature, limited data exists HGO model. Furthermore, no peer-reviewed comparis...

Landing gear is one of the critical subsystems of an aircraft. The need to design landing gear with minimum weight, minimum volume, high performance, improved life, and reduced life cycle cost have posed many challenges to landing gear designers and practitioners. Further, it is essential to reduce the landing gear design and development cycle time while meeting all the regulatory and safety re...
