Both attempts depend on specific techniques and tactical skills supported by good physical fitness.<a href="#bib2" class="elsevierStyleCrossRefs"><span class="elsevierStyleSup">2</span></a> Judo techniques, such as throws, armlocks, choking and immobilization techniques, tax both anaerobic alactic and lactic energy transfer systems.<a href="#bib3" class="elsevierStyleCrossRefs"><span class="elsevierStyleSup">3</span></a> Considering the contest duration and the number of contests during a tournament, aerobic capacity is also important in terms of better use of the judoka's system and the prompt recuperation process.<a href="#bib4" class="elsevierStyleCrossRefs"><span class="elsevierStyleSup">4</span></a></p><p class="elsevierStylePara"> The evaluation of physical characteristics is an important part of the training process because it gives information about the variables that need improvement and about the effectiveness of a given training program.<a href="#bib5" class="elsevierStyleCrossRefs"><span class="elsevierStyleSup">5</span></a> Physiological testing is commonly used to assess the overall fitness level of the athletes and to set guidelines for individualized training.<a href="#bib6" class="elsevierStyleCrossRefs"><span class="elsevierStyleSup">6</span></a> In laboratory setting, aerobic power typically is assessed through maximal or submaximal tests, performed on ergometer, while anaerobic power is assessed through maximal tests (e.g., Wingate anaerobic test, Force-velocity test and Bosco test). Although laboratory tests provide valid and reliable results, they cannot reproduce realistically the sport movement patterns, and therefore the need for sport-specific test in judo has been evolved. Several field tests have been proposed. Among them, a judo-specific ability test, consisting by 10 stations, in which adolescent judokas performed physical ability and skill tasks, did not correlate with performance ranking, and therefore it was not sensitive enough to accurately measure talent.<a href="#bib7" class="elsevierStyleCrossRefs"><span class="elsevierStyleSup">7</span></a></p><p class="elsevierStylePara"> On the other hand, the special judo fitness test (SJFT), which has been proposed by Sterkowicz, is considered as useful training tool.<a href="#bib8" class="elsevierStyleCrossRefs"><span class="elsevierStyleSup">8</span></a> Blood lactate concentration after the SJFT was very similar to that obtained after judo combat, indicating similar metabolic responses in these situations.<a href="#bib9" class="elsevierStyleCrossRefs"><span class="elsevierStyleSup">9</span></a> Sterkowicz and Franchini observed that elite Polish judokas (medalist in the National Championship) presented a better SJFT index compared with athletes representing a lower sport level and that competitors of light weights categories presented a better index than judokas of heavier categories.<a href="#bib10" class="elsevierStyleCrossRefs"><span class="elsevierStyleSup">10</span></a> In addition, Franchini et al. found that athletes with superior age to 16 years of age submitted to the same training type tend to have similar performance in the SJFT.<a href="#bib11" class="elsevierStyleCrossRefs"><span class="elsevierStyleSup">11</span></a></p><p class="elsevierStylePara"> To the best of our knowledge, the association between SJFT with laboratory assessment methods of physical fitness has not been studied. Therefore, the purpose of this study was to assess the relationship between aerobic and anaerobic power and results of SJFT in Iranian male national judo athletes.</p><p class="elsevierStylePara"><a name="sec0010" class="elsevierStyleCrossRefs"></a></p><span class="elsevierStyleSectionTitle"> Materials and methods</span><p class="elsevierStylePara"><a name="sec0015" class="elsevierStyleCrossRefs"></a></p><span class="elsevierStyleSectionTitle"> Participants</span><p class="elsevierStylePara"> In this investigation, a descriptive-correlation design was used to examine the association between laboratory measures of aerobic and anaerobic power, and the SJFT. The local Institutional Review Board approved and National Judo Federation supported the study. Written informed consent was obtained from all athletes after verbal explanation of the experimental design and potential risks of study. Exclusion criteria included history of any chronic medical conditions and use of any medication. Nineteen elite judokas, including 11 members of Iranian National Team and eight national-level athletes, who were invited to the national training camps, volunteered for our study [age 24.3 (3.1) yr, mean (SD), height 1.779 (.063) m, body mass 76.4 (11.2) kg, body mass index 20.2 (3.6) kg·m<span class="elsevierStyleSup">−2</span> and body fat 11.0 (1.8)%]. All participants competed to official games in weight categories −60 kg, −66 kg, −73 kg, −81 kg and −90 kg.</p><p class="elsevierStylePara"><a name="sec0020" class="elsevierStyleCrossRefs"></a></p><span class="elsevierStyleSectionTitle"> Measures</span><p class="elsevierStylePara"> The study was conducted during four consecutive days. In the first day, anthropometric and body composition data were recorded, and in the following days, SJFT, Wingate anaerobic test (WAnT) and graded exercise test (GXT) were performed respectively, always after a guided standardized 15-min warm-up. An electronic weight scale (HD-351 Tanita, Illinois, USA) was employed for body mass measurement (in the nearest .1 kg), a portable stadiometer (SECA, Leicester, UK) for stature (.001 m), a body composition analyzer (TBF-410 Tanita, Illinois, USA) for percentage of body fat (BF), and body mass index was calculated.</p><p class="elsevierStylePara"><a name="sec0025" class="elsevierStyleCrossRefs"></a></p><span class="elsevierStyleSectionTitle"> Procedures</span><p class="elsevierStylePara"> Maximal oxygen uptake (VO<span class="elsevierStyleInf">2</span>max) was estimated by a GXT (Bruce protocol test) on a treadmill (HC1200 Technogym, Gambettola, Italy), which included six 3-min stages against incremental speed (from 2.74 km·h<span class="elsevierStyleSup">−1</span> to 8.85 km·h<span class="elsevierStyleSup">−1</span>) and inclination (from 10% to 20%). Total time (<span class="elsevierStyleItalic">T</span>) was recorded in minutes and VO<span class="elsevierStyleInf">2</span>max was calculated as VO<span class="elsevierStyleInf">2</span>max (mL·kg<span class="elsevierStyleSup">−1</span>·min<span class="elsevierStyleSup">−1</span>) = 14.8 − 1.379·<span class="elsevierStyleItalic">T</span> + .451·<span class="elsevierStyleItalic">T</span>2 − .012·<span class="elsevierStyleItalic">T</span>3.</p><p class="elsevierStylePara"> Anaerobic power was measured by the WAnT. This test was performed on an arm-cranking ergometer (881E Monark, Varberg, Sweden). Braking force for the 30-s WAnT was determined by the product of body mass in kg by .05. Participants were instructed before the test that they should pedal as fast as possible and they were verbally encouraged throughout the test. Compared with the other tests, WAnT has the advantage that it provides information about both alactic and lactic anaerobic energy transfer system. The main indices of this test are: (a) peak power (Ppeak), the highest power elicited from the test taken as the average power of any 5-s period and (b) mean power (Pmean), the average power during the 30-s test, minimal power. Regarding the taxing of human energy transfer systems during the test, Ppeak is considered as a descriptor of short-term power output that relies mainly upon adenosine triphosphate-creatine phosphate (alactic anaerobic system), and Pmean as a descriptor of local muscular endurance that relies mainly upon anaerobic glycolysis resulting in lactate production (lactic anaerobic system).</p><p class="elsevierStylePara"> Athletes performed the sport-specific test proposed by Sterkowicz, according to the following protocol: two judokas with similar height and body mass (same category) are positioned at 6 m distance from one another, while the test executor (tori) is 3-m from the judokas. The procedure is divided into three periods: 15-s (A), 30-s (B), and 30-s (C) with 10-s intervals among them. During each period, the executor throws partners using the ippon-seoi-nage technique, as many times as possible. Heart rate (HR) is recorded immediately and one minute after the cessation of the test by HR monitor (Sport-tester Polar Electro, Kempele, Finland). On the basis of the obtained results, the index (<span class="elsevierStyleItalic">I</span><span class="elsevierStyleInf">SJFT</span>) was calculated:</p><p class="elsevierStylePara"><span class="elsevierStyleItalic">I</span><span class="elsevierStyleInf">SJFT</span> = (HR after effort + HR after 1 min since effort completed)/[sum of throws (series A + series B + series C)]</p><p class="elsevierStylePara">  </p><p class="elsevierStylePara"><a name="sec0030" class="elsevierStyleCrossRefs"></a></p><span class="elsevierStyleSectionTitle"> Analysis</span><p class="elsevierStylePara"> All statistical analyses were performed with using SPSS 13.0 (SPSS Inc., Chicago, IL, USA).

However, what was the most important finding was the strong correlation between aerobic and anaerobic power with performance in the SJFT. It was showed that the SJFT is a field test that describes chiefly aerobic power, and in a lesser degree short-term power output and local muscular fatigue. Therefore, its further use from judo coaches and fitness trainers as a measure to monitor aerobic power is recommended, and the need for a field test that will describe anaerobic power is highlighted. Moderate correlations between SJFT and indices of aerobic and anaerobic power were indicated in the past in a study in which the number of throws in the SJFT was correlated with anaerobic threshold velocity (<span class="elsevierStyleItalic">r</span> = .60, <span class="elsevierStyleItalic">p</span> < .01), peak velocity in incremental test (<span class="elsevierStyleItalic">r</span> = .70, <span class="elsevierStyleItalic">p</span> < .01) and countermovement jump (<span class="elsevierStyleItalic">r</span> = .74, <span class="elsevierStyleItalic">p</span> < .01).<a href="#bib22" class="elsevierStyleCrossRefs"><span class="elsevierStyleSup">21</span></a></p><p class="elsevierStylePara"> The significant correlation of SJFT with both aerobic and anaerobic power was not unexpected, as there are high requirements for both in judo.
