The human limbs are paired organs, each capable of independent movement. Functional laterality is found in the upper limbs when writing letters or throwing a ball, etc. This study aimed to examine the effects of differences in manipulation leg (ML), defined as the leg used when kicking a ball and supporting leg (SL), as the contralateral leg, and moving target speed on a visual tracking test us...

The first purpose of this chapter is to review research that shows that women initiate and carry out physical assaults on their partners as often as men do. A second purpose is to show that, despite the much lower probability of physical injury resulting from attacks by women, assaults by women are a serious social problem, just as it would be if men “only” slapped their wives or “only” slapped...

OBJECTIVE To examine the effect of age, sex and obesity on Fundamental Motor Skills (FMS) in 4 to 6 years-old children. METHODOLOGY A total of 400 preschool children (200 boys and 200 girls) between the ages of 4 to 6 years old participated in this research. Subjects were selected through multi-stage cluster random sampling. Fundamental motor skills (FMS) were assessed with using the OSU-SIGM...

Non-generic feedback refers to a specific event and implies that performance is malleable, while generic feedback implies that task performance reflects an inherent ability. The present study examined the influences of generic versus non-generic feedback on motor performance and learning in 10-year-old children. In the first experiment, using soccer ball kicking at a target as a task, providing...

This article examines two widely held beliefs concerning the nature of “careers” of wtfe assault. Most researchers and members of the public believe that assaultive behavior in marriage, once begun, tends to continue for the ltfe of the marriage. It is also commonly believed that minor violence (e.g., slapping, shoving, throwing things at a spouse) is unrelated to severe assaults (e.g.. punchin...

BACKGROUND Despite the recognized importance of proper 3-dimensional motion of the scapula in throwers, minimal research has quantified scapular position and orientation in throwing athletes. HYPOTHESIS Throwing athletes exhibit scapular position and orientation differences when compared to nonthrowing control subjects. STUDY DESIGN Descriptive laboratory study. METHODS Scapular position ...

BACKGROUND Despite widespread use of long-toss throwing in baseball as a component of arm conditioning, interval throwing programs, and rehabilitation, long-toss distance and throwing mechanics remain controversial. PURPOSE To ascertain the perceived definition of long-toss throwing through a survey of professional pitchers, pitching coaches (PCs), and certified athletic trainers (ATCs) assoc...

Baseball-specific athleticism, potential, and performance have been difficult to predict. Increased muscle strength and power can increase throwing velocity but the majority of research has focused on the upper body. The present study sought to determine if bilateral or unilateral lower-body field testing correlates with throwing velocity. Baseball throwing velocity scores were correlated to th...

BACKGROUND Glenohumeral internal rotation (GIR) and total arc of motion (TAM) decrease, whereas external rotation (GER) may increase in throwing. Although decreased GIR has been documented after throwing, its time course for recovery and the effect of pitching role have not. QUESTIONS/PURPOSES We therefore asked (1) how much rotational change occurs after a single throwing episode; (2) do the...
