In order to decrease the amount of time that it takes the catcher to throw the ball, a catcher may chose to throw from the knees. Upper extremity kinematics may play a significant role in the kinetics about the elbow observed in catchers throwing from the knees. If relationships between kinematics and kinetics exist then the development of training and coaching instruction may help in reduced u...

Summarized under the term Transport-by-Throwing, robotic arms throwing objects to each other are a visionary system intended to complement the conventional, static conveyor belt. Despite much research and many novel approaches, no fully satisfactory solution to catch a ball with a robotic arm has been developed so far. A new approach based on memorized trajectories is currently being researched...

ABSTRACT Introduction In badminton performance, athletes need to precisely manage the movements of mastered techniques quickly complete swing and regroup strength upper lower limbs hit ball quickly. Objective Study effect exercise on physical performance players according training. Methods 24 were randomly divided into limb, control groups. The limb group trained for eight weeks. final test was...

The purpose of this study was to assess the motor competence children with and without amblyopia. Study participants were 165 primary school children, aged 6–9 years, divided into three groups based on their visual acuity Snellen chart: (a) non-amblyopia, (b) corrected amblyopia, (c) non-corrected We assessed children’s Motor Competence Assessment battery (MCA) physical activity Physical Activi...

Joint range of motion and physical capacities have been shown to change with age in both throwing athletes and non-athletes. The age of professional baseball pitchers could span from late teens to mid-40s. However, the effects of age on the pitching kinematics among professional baseball pitchers are still unknown. In this study, 67 healthy professional baseball pitchers were tested using a 3D ...

Abstract The purpose of this study was to evaluate three distinct methods teaching the three-step ball throw simulating javelin technique primary school students. sample consisted 131 students 5th and 6th grade (Mage = 11.4, SD 0.47 years) randomly divided into groups. control group (CON) received typical instruction, first experimental (EXP) followed a blended learning intervention which inclu...

Progesterone (P4) was demonstrated to inhibit migration in vascular smooth muscle cells (VSMCs), but to enhance migration in T47D breast cancer cells. To investigate the mechanism responsible for this switch in P4 action, we examined the signaling pathway responsible for the P4-induced migration enhancement in breast cancer cell lines, T47D and MCF-7. Here, we demonstrated that P4 activated the...

The fixed duration of a team-handball game and its continuously changing situations incorporate an inherent temporal pressure. Also, the target's position is not foreknown but online determined by the player's interceptive processing of visual information. These ecological limitations do not favour throwing performance, particularly in novice players, and are not reflected in previous experimen...
