This study examined how the central nervous system organizes mediolateral (ML) "anticipatory postural adjustments" (APAs) for stepping initiation (SI) to take into account the postural perturbation induced by voluntary lateral arm raising. Subjects purposely stepped in isolation ("isolated stepping") or in combination with lateral raising of dominant arm ("motor sequence"). SI was carried out w...

The purpose of this study was to analyze the differences in standing balance during dominant and nondominant one-legged stance among athletes of different sports and sedentary subjects. The right-footed subjects of four groups (sedentary, n = 20; soccer, n = 20; basketball, n = 20; windsurfer n = 20) underwent 5-sec unipedal (left and right foot) stabilometric analysis with open eyes and closed...

Abstract Objective To verify the effects of successive judo matches on interlimb asymmetry and bilateral deficit in athletes. Design Repeated measures; Setting University Judo center. Participants Fourteen male Outcome measures Four simulated consisting 4-min. Before first match after each athletes were submitted to single leg tests – Countermovement Jump (SLCMJ) Standing Long (SLSLJ), handgrip...

Dexterous manipulation depends on using the fingertips to stabilize unstable objects. The Strength-Dexterity paradigm consists of asking subjects to compress a slender and compliant spring prone to buckling. The maximal level of compression [requiring low fingertip forces <300 grams force (gf)] quantifies the neural control capability to dynamically regulate fingertip force vectors and motions ...

BACKGROUND The aim of this study is to verify the effects of the combined and classic training of different isometric rates of force development (RFD) parameters of legs. MATERIALS AND METHODS THREE GROUPS OF FEMALE ATHLETES WAS TESTED: Experimental group (N = 12), classically trained group (N = 11), and control group (N = 20) of athletes. The isometric "standing leg extension" and "Rise on T...

To comprehend a pun involving a homonym (e.g., The prince with a bad tooth got a crown), both meanings of the homonym must be accessed and selected. Previous ERP studies have shown that the N400 reflects lexicosemantic processing, but none have directly investigated the N400 elicited by homonyms in the unique context of puns. Here, N400 priming effects showed that the dual context of puns (e.g....

The aims of this study were to describe body composition and physical fitness changes during a wholeseason in elite children tennis players. A total of 7 elite children tennis players participated in the study. Whole body composition by dual energy X-ray absorptiometry (DXA) and physical fitness were assessed during a season. Subjects increased lean and bone percentage, and decreased abdominal ...

OBJECTIVES: To analyze the effects of motor learning on knee extension-flexion isokinetic performance in knee osteoarthritis patients. METHODS: One hundred and thirty-six middle-aged and older sedentary individuals (111 women, 64.3±9.9 years) with knee osteoarthritis (130 patients with bilateral) and who had never performed isokinetic testing underwent two bilateral knee extension-flexion (co...

OBJECTIVE To provide the off-loading knee brace was designed relief for the pain associated with osteoarthritis by reduce loads on the degenerative compartment of the knee. This study examined the effects of the off-loading knee brace on activation of femoral muscles during squatting, slow and fast walking exercise in healthy young individuals. METHOD Ten healthy male subjects without a histo...

Femoral slump test is a neurodynamic testing, which could be used to assess the mechanosensitivity of the femoral component of the nervous system. Although Trainor and Pinnington reported the diagnosis accuracy of the femoral slump test, the neurodynamic responses of the femoral slump test have never been studied. The purposes of this study were to evaluate whether maneuvers that changed the ne...
