Falls are a very dangerous situation especially among elderly people, because they may lead to fractures, concussion, and other injuries. Without timely rescue, falls may even endanger their lives. The existing optical sensor-based fall monitoring systems have some disadvantages, such as limited monitoring range and inconvenience to carry for users. Furthermore, the fall detection system based ...

An enhanced fall detection system is proposed for elderly person monitoring that is based on-body sensor operating through consumer home networks and Internet of things(IoT). The on-body sensor which consists of accelerometer and cardio tachometer is used in this model. In this proposed system accelerometer measures overall vibration by means of using Signal Magnitude Vector and trunk angle. He...

purpose the objectives of this study include: (1) determination of the attenuation of strike acceleration that tae kwon do sparring safety pads provide from kicks from olympic style tkd fighters, (2) the sex and weight differentiation in acceleration achieved within the thorax model with the roundhouse kicks. methods this prospective, observational study utilized 15 olympic style fighters from ...

On the circular curve, lateral acceleration affects comfort. On the spiral, both lateral acceleration and jerk affect comfort.  The determination of maximum curving speed on the basis of lateral acceleration only is not critical because the lateral acceleration is proportional to the square of speed whereas jerk is proportional to cubic power of speed. The maximum speed on a curve is thus signi...

PURPOSE To investigate the relationship between repeated high-intensity-effort (RHIE) ability and selected physical qualities in rugby league players. METHODS Sixteen rugby league players underwent measurements of upper-body strength (4-repetitionmaximum [4RM] bench press, weighted chin-up, weighted dips), upper-body muscle endurance (body-mass maximum-repetition chin-up, body-mass maximum-re...

Neuromuscular control of posture as understood through studies of responses to mechanical sudden acceleration automatically has been previously demonstrated in individuals with chronic ankle instability (CAI), but the presence of acute condition has not been previously explored specially in a sudden acceleration. The aim of this study was to determine neuromuscular control pattern in those with...

Induced acceleration analysis quantifies the contributions of individual moments and forces to the accelerations, reaction forces, and powers produced during a task. The analysis has been advocated in the assessment of muscle and joint moment function during locomotion. However, results and interpretations drawn from the analysis have differed considerably between studies. The purpose of this p...

The purpose of this study was to determine the muscular contributions to the acceleration of the whole body centre of mass (COM) of older compared to younger adults that were able to recover from forward loss of balance with a single step. Forward loss of balance was achieved by releasing participants (14 older adults and 6 younger adults) from a static whole-body forward lean angle of approxim...

Diving animals modulate their swimming gaits to promote locomotor efficiency and so enable longer, more productive dives. Beaked whales perform extremely long and deep foraging dives that probably exceed aerobic capacities for some species. Here, we use biomechanical data from suction-cup tags attached to three species of beaked whales (Mesoplodon densirostris, N=10; Ziphius cavirostris, N=9; a...
