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">
