in the present study, interactive effects of d1 and d2 dopamine receptors antagonists and different periods of lithium pretreatment on morphine dependence in mice have been investigated. this study was designed to investigate whether the hypothesis that lithium and dopaminergic mechanisms via their effects on phosphoinositide pathways and calcium flux could influence morphine withdrawal respons...

Jumping: There are a limited number of studies available evaluating the efficiency of interventions aiming to reduce numbers of suicides by jumping. They are limited to sites that have over the years acquired a status of iconic suicide ‘hot-spots’. There are no studies reporting on the efficiency of such interventions in reducing suicide attempts, possibly because suicide by jumping is consider...

The purpose of this study was to use a holistic approach to investigate changes in jumping performance, kinaesthesia, static balance, isometric strength and fast stepping on spot during a 5-day recovery period, following an acute bout of damaging exercise consisted of drop jumps and leg curls, where specific emphasis was given on the hamstring muscles. Eleven young healthy subjects completed a ...

Background: Jumping and landing are common activities in soccer, i.e., associated with Anterior Cruciate Ligament (ACL) injuries in the players, especially when experiencing fatigue. The current study aimed to compare the kinematics of the lower limb joints in jump-landing maneuver among soccer players with and without a history of anterior cruciate ligament reconstruction. Methods: Among acti...

This study determined the comparative effect of three modes of Plyometrics training [depth jumping, rebound jumping and horizontal jumping] on leg muscle strength of untrained University male students. Participants were forty untrained male University students within the age range of 18-27 years. The randomized pretest-posttest control group design was adopted. Subjects were randomly assigned t...

PURPOSE To determine the effects of creatine (Cr) supplementation (20 g x d(-1) during 5 d) on maximal strength, muscle power production during repetitive high-power-output exercise bouts (MRPB), repeated running sprints, and endurance in handball players. METHODS Nineteen trained male handball players were randomly assigned in a double-blind fashion to either creatine (N = 9) or placebo (N =...
