With the purpose of investigating motor and cognitive lateralization profiles associated with long-term motor training, we investigated differences in hemispheric specialization between proficient judo sportsmen and controls through the assessment of a number of handedness and footedness items including postural preferences as well as dichotic listening and lateralized visual field tests. Our d...

BACKGROUND Sports that require the constant use of an upper limb demand the maximum kinetic chain efficiency in this segment. Immaturity of the musculoskeletal system, followed by failure in motor skills can expose adolescents to major reports of pain complaints, particularly for the shoulder. OBJECTIVE To evaluate the prevalence of shoulder pain in adolescent athletes and identify possible f...

We have traditionally viewed spam from the receiver’s point of view: mail servers assaulted by a barrage of spam from which we must pick out a handful of legitimate messages. In this paper we describe a system for better filtering spam by exploiting the vantage point of the spammer. By instantiating and monitoring botnet hosts in a controlled environment, we are able to monitor new spam as it i...

OBJECTIVE To assess energy demand during a judo match and the kinetics of recovery by measuring the metabolites of the oxypurine cascade, lipolytic activity, and glycolytic pathway. METHODS Venous blood samples were taken from 16 national judoists (mean (SEM) age 18.4 (1.6) years), before (T(1)) and three minutes (T(2)), one hour (T(3)), and 24 hours (T(4)) after a match. A seven day diet rec...

OBJECTIVES Considering that this ranking system provides useful information concerning athletes' performance in competitions during a 2-year period and during Olympi...

Arginine supplementation has been shown to induce endothelium-dependent vasodilation and enhance exercise performance via increasing nitric oxide (NO) production in patients with various cardiovascular diseases. The purpose of this study was to determine the effect of short-term arginine supplementation on vasodilation and performance in intermittent anaerobic exercise in well-trained male athl...

Background The supplementation of standard diets with creatinebased compounds in speed-and-strength sports has become very popular today. The creatine alone is an endogenous substance synthetized in internal organs, such as liver, pancreas and kidneys. Primary stores of free creatine (Cr) and its phosphorylated form (PCr) are skeletal muscles, cardiac muscle and smooth muscle tissues. Since the...

Berdasarkan hal ini maka atlet seharusnya tinggi. Tujuan penelitian melihat empat cabang (cabor) (jud...

PURPOSE The aim of this study was to compare the impact of the practice of football and judo on lung function and aerobic performance of prepubertal boys. METHODS A total of ninety six prepubertal boys were studied. They assessed a measure of body composition using the skin folds method. They performed lung plethysmography at rest, followed by an incremental exercise test. RESULTS There was...
