Calendário da FIJ

Como manter uma modalidade com caráter internacional, com uma grande concentração de competições na Europa e Ásia, um pouquinho nas Américas, duas na Oceania e nenhuma na África (excetuando o continental)? Deve estar reservada uma para a África (o Grand Slam a ser confirmado)...

Abstract

The aim of this study was firstly to investigate the correlation between bone parameters and grip strength (GS) in hands, explosive legs power (ELP), and hormonal parameters; second, to identify the most determinant variables of bone mineral density (BMD) among adolescent combat sport athletes. Fifty combat sport athletes aged 17.1±0.2yr were compared with 30 sedentary subjects matched for age, height, and pubertal stage. For all subjects, the BMD in deferent sites associated with anthropometric parameters were measured by dual-energy X-ray absorptiometry. The growth hormone (GH) and testosterone (TESTO) concentrations were tested. The GS in dominant (GSDA) and nondominant arms (GSNDA) and ELP were evaluated. All BMD measured were greater in athletes than in sedentary group (p<0 .01=".01" all="all" and="and" arms="arms" athletes="athletes" best="best" bmd="bmd" body="body" both="both" but="but" class="highlight" combat="combat" correlated="correlated" correlation="correlation" effect="effect" elp="elp" especially="especially" gh="gh" group="group" gs="gs" gsnda.="gsnda." gsnda="gsnda" has="has" height.="height." higher="higher" in="in" is="is" legs.="legs." measurements="measurements" nbsp="nbsp" of="of" only="only" osteogenic="osteogenic" p="p" practice="practice" predictor="predictor" proved="proved" sedentary="sedentary" showed="showed" significantly="significantly" sites="sites" span="span" spine="spine" sports="sports" study="study" style="border: 0px; font-size: 13px; font: inherit; margin: 0px; padding: 0px; vertical-align: baseline;" testo="testo" than="than" the="the" this="this" values="values" was="was" weight="weight" were="were" whole="whole" with="with" without="without">judo

Abstract

The objective of this study is to examine the sensitivity to and changes in heart rate variability (HRV) in stressful situations before judo competitions and to observe the differences among judo athletes according to their competitive standards in both official and unofficial competitions. 24 (10 male and 14 female) national- and international-standard athletes were evaluated. Each participant answered the Revised Competitive State Anxiety Inventory (CSAI-2R) and their HRV was recorded both during an official and unofficial competition. The MANOVA showed significant main effects of the athlete's standard and the type of competition in CSAI-2R, in HRV time domain, in HRV frequency domain and in HRV nonlinear analysis (p<0 .05=".05" 5="5" a="a" analysis="analysis" and="and" anxiety.="anxiety." anxiety="anxiety" athletes.="athletes." athletes="athletes" by="by" changes="changes" cognitive="cognitive" conclusion="conclusion" confidence="confidence" consecutive="consecutive" deviation="deviation" differ="differ" difference="difference" exponent="exponent" exponents="exponents" frequency="frequency" have="have" heart="heart" higher="higher" hrv="hrv" in="in" international-standard="international-standard" interval="interval" intervals="intervals" is="is" judo="judo" less="less" long-range="long-range" long-term="long-term" low-high="low-high" lower="lower" mean="mean" more="more" ms="ms" national-standard="national-standard" number="number" of="of" p="p" pre-competitive="pre-competitive" rate="rate" ratio="ratio" root="root" rr="rr" scaling="scaling" sensitive="sensitive" short-range="short-range" short-term="short-term" show="show" somatic="somatic" square="square" squared="squared" standard="standard" successive="successive" than="than" that="that" the="the" to="to" variability="variability">
