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).

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.

Abstract

PURPOSE:

Weight loss in wrestling has been found to be an interesting issue for researchers. In this regard, complications of weight loss in wrestlers before the competitions and their weight gain in course of competitions have been debated in previous studies. The objective of this study was to investigate the extent of weight gain and to estimate the percentage of body fat in participants in the Tehran high school male wrestlingchampionship.

METHODS:

This study was a cross sectional survey. Subjects were participants of the Tehran high school male wrestling championship (n = 365). Weight gain in course of competitions and body fat levels (based on skin fold measurements) of subjects were measured.

RESULTS:

Between the first weigh-in of the wrestlers which was done one day before the competitions and the second weigh-in which was conducted immediately before the first round of their first competition (20 hours), 69% of subjects gained on average 1.3±0.9 kg (range: 0.1 to 6.10 kg) or 2.2±1.7% of the wrestler's weight (range: 0.1 to 9.3). Among the subjects, the mean of fat body percentage was found to be 15.2%.

CONCLUSIONS:

Rapid weight loss for matches was prevalent among subjects. It was also found that Iranian wrestlers have a relatively higher body fat percentage in comparison to American wrestlers. Therefore, it can be concluded that weight loss behavior of these wrestlers should be changed from using dehydration methods to using gradual methods of weight loss such as fat reduction methods.
