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">

ABSTRACT:

Background

The purpose of the study was to determine the effect of 6-weeks training and creatine malate supplementation demonstrated in anaerobic capacity and aerobic power and in special judo fitness test performance (Throws in Total and Index in SJFT).

Methods

Ten professional competitors aged 21.2+/-3.3 years and practicing judo for 11+/-4.5 years participated in a typical pre-competition training program. Their height and weight during the first measurement were 1.75+/-0.06 m and 76.09+/-14.85 kg, respectively. Subjects participated in the same training sessions. The contestants have been training for approximately 20 hours a week: 5 days for 2 two-hour-training sessions. They used their usual diets. They were randomly selected to a treatment group who were administered the creatine malate (n=5) whereas the controls were receiving a placebo (n=5). All subjects were tested for anaerobic capacity (the Wingate-test) and aerobic power (the progressive test), and in the SJFT test, pre and post a six-week training during preparation period. We have used double-blind placebo-controlled design.

Results

Multifaceted judo training before competition caused a significant (z=2.40, P<0 .05=".05" 3.68="3.68" 78.52="78.52" an="an" anaerobic="anaerobic" and="and" bmi="bmi" body="body" but="but" capacity="capacity" cause="cause" contributed="contributed" control="control" creatine="creatine" did="did" diet="diet" difference="difference" fat="fat" fm="fm" fmi="fmi" focus="focus" group="group" higher="higher" in="in" increase="increase" increased="increased" increment="increment" index="index" indices="indices" kg="kg" malate="malate" mass="mass" me="3.78" n="10)." not="not" observed="observed" obtain="obtain" on="on" p="p" particular="particular" peak="peak" percent="percent" power="power" repectively="repectively" sec="sec" shortening="shortening" significant="significant" supplementation="supplementation" than="than" the="the" there="there" time="time" to="to" topp="topp" vs.="vs." was="was" with="with" z="2.40,">0.05). However, the groups differed in the post-test moment in the fatigue index (FI) (T=48.7+/-5, Me=46.1 vs. C=41.1+/-3, Me=40.4%, Z=1.98, P<0 .05=".05" aerobic="aerobic" and="and" between="between" differences="differences" levels="levels" no="no" observed="observed" of="of" p="p" post-experiment="post-experiment" power="power" pre-="pre-" significant="significant" were="were" whereas="whereas">0.05). Percent at VO2max at the anaerobic threshold (%VO2max), in the first measurement showed no significant differences between two groups, while in the second measurement statistically significant differences were observed: in T group %VO2max was higher (85.43+/-6.35, Me=85.5% vs. 76.13+/-3.48, Me=75.3%, Z=2.09, P<0 .05=".05" a="a" and="and" be="be" but="but" by="by" caused="caused" changes="changes" comparison="comparison" creatine="creatine" differences="differences" expressed="expressed" for="for" found="found" general="general" in="in" index="index" malate="malate" me="28.5" measurement="measurement" measurements="measurements" neither="neither" no="no" nor="nor" not="not" observed="observed" of="of" p="p" post-test="post-test" post="27.9+/-2.4," pre="26.9+/-2.7," pretests="pretests" reflected="reflected" results="results" significant="significant" sjft.="sjft." sjft="sjft" such="such" supplementation="supplementation" the="the" these="these" throws="throws" to="to" total="total" vs.="vs." was="was" were="were" with="with" z="2.67,">0.05).

Conclusions

The multifaceted judo training is conducive to the development of both FM and FMI. Use of supplementation of the diets with creatine malate does not cause an increase in body mass greater than in the control group. Shorter time to obtain peak power (toPP) is conducive to faster execution of rapid planned actions in attack or defense. Pre and post-training aerobic power did not change so it was not supplementation-dependent. Creatine malate did not affect the results in SJFT. There are many determinants of the judo fight results e.g. technical, tactical, physiological and psychological factors, one of them could be supplementation but it cannot be treated as a separate improving factor. The significant improvement in Total Throws in SJFT with the unchanged Index in SJFT suggests better neuromuscular adaptations compared to those occurring in circulatory and respiratory systems. The results obtained during the SJFT test depend not only on energy resources but also on the exercises which improve the technique of performing typical grip-and-throw judo actions, despite the ensuing fatigue. Key words: judo, training effect, creatine malate supplementation, anaerobic capacity, aerobic power, special fitness

Abstract

PURPOSE:

Judo is a complex sport where different anthropological parameters determine performance. Judo, as a sport is not well known in India. There is evident lack of data concerning the anthropological determinants of judo players. This study was conducted to determine the anthropometric profile and Special Judo Fitness levels of judokas.

METHODS:

This cross sectional study was conducted on 31 judo players. Anthropometric profile was assessed by measuring height, weight, body mass index, body circumferences at seven sites, seven site skin fold thickness and body fat percentage as per standard accepted protocol. SpecialJudo Fitness Test - a specific test to evaluate the judo athlete's physical condition was applied. Statistical analysis done using Student's unpaired 't' test and correlation by Karl Pearson's correlation coefficient.

RESULTS:

Out of 31 judo players 20 had ≤5 yrs of judo practice (A group) and 11 >5 yrs of judo (B group). Anthropometric findings of both the judogroups were the same. Body fat has negative correlation (r =-0.690, P<0 .05=".05" after="after" and="and" class="highlight" during="during" in="in" nbsp="nbsp" observations="observations" performance="performance" sjft.="sjft." span="span" special="special" style="border: 0px; font-size: 13px; font: inherit; margin: 0px; padding: 0px; vertical-align: baseline;" with="with">judo

fitness test were also similar.

CONCLUSIONS:

Long term training has a minimal effect on anthropometry. Judo athletes of similar age when submitted to the same training type tend to show equal performance in the game and fitness levels after certain years of training. We also confirm existence of negative correlation between body fat and performance.
