High-impact exercise is considered to be very beneficial for bones. We investigated the ability of jump exercise to restore bone mass and structure after the deterioration induced by tail suspension in growing rats and made comparisons with treadmill running exercise. Five-week-old male Wistar rats (n = 28) were randomly assigned to four body weight-matched groups: a spontaneous recovery group ...

Conclusion Jumping of legged mobile robots has been a highly motivated research area. When a running robot encounters obstacles comparable to its body height, jumping is one of the most effective ways to overcome them. Also, if the robots can jump over gaps or crevices, the mobility of robots in a wild field would be enhanced drastically.The jumping performance is dependent on the terrain prope...

introduction: morphine withdrawal syndrome is mediated via several central and peripheral neurological pathways. in the present study we investigated the role of n-methyl-d aspartic acid (nmda) glutamate receptor on naloxone-induced withdrawal syndrome in morphine-conditioned mice. materials and methods: we designed two separate experiments. in experiment one, 30 male nmri mice were divided int...

Frogs are characterized by a morphology that has been suggested to be related to their unique jumping specialization. Yet, the functional demands associated with jumping and swimming may not be that different as suggested by studies with semi-aquatic frogs. Here, we explore whether features previously identified as indicative of good burst swimming performance also predict jumping performance i...

Objectives: New cognitive theories of delusions have proposed that deficit or bias in inference stage (a stage of normal belief formation) is significant in delusion formation. The aim of this study was predicting the severity of delusions based on jumping-to-conclusion bias in patients with schizophrenia. Methods: The sample consisted of 60 deluded patients with schizophrenia w...

The aim of this paper is to study jumping numbers and multiplier ideals of any ideal in a two-dimensional local ring with a rational singularity. In particular we reveal which information encoded in a multiplier ideal determines the next jumping number. This leads to an algorithm to compute sequentially the jumping numbers and the whole chain of multiplier ideals in any desired range. As a cons...

In ski jumping low body weight development resulted in some serious underweight problems and therefore International Ski Federation (FIS) decided to solve the problem by relating maximum ski length to Body Mass Index (BMI). The present study examined the current relationship between body weight (BMI), ski length and performance (jumping distance) in ski jumping. The computer simulation showed t...

BACKGROUND Hamstring injuries are the most common muscle injury in amateur and professional soccer. Most hamstring injuries occur in the late swing phase, when the hamstring undergoes a stretch-shortening cycle and the hamstring does a significant amount of eccentric work. The incidence of these injuries has not decreased despite there being effective injury prevention programmes focusing on im...
