An additional aim was to examine the effect of supplementation with creatine malate on body Epigenetics inhibitor composition and physical capacity indices and special fitness of judoists. Methods Subjects Age of the male subjects (n = 10) who took part in the study ranged from 17 to 28 years with the average of 21.2±3.3 years, whereas their training experience ranged from 5 to 21 years (11±4.5 years). Three of them had 2nd Kyu judo rank, three of the subjects had 1st Kyu and four of them had 1st Dan level. Procedures

Body height, PI3K inhibitor measured by means of Martin’s anthropometer, varied from 1.68 to 1.87 m (1.75±0.06 m). Measurements of body mass (BM) were taken with the accuracy ±1g by means of F1505-DZA Sartorius (Germany) scales. Measurements were Crenigacestat ic50 carried out according to the recommendations in kinanthropometry [12]. The three consecutive measurements of two skinfolds (triceps and subscapular) were taken with GPM skinfold caliper with measurement range 0–45 mm ± 0.2 mm, made in Switzerland, further

on intra-observer error was counted. Typical error of skinfolds measurement [13] were 1.8% for triceps, and 2.0% for subscapular. The both measurement were within proper anthropometric tolerance (5%), which is recommended for skinfolds measurements [12]. Intraclass correlation coefficients 3,1 (ICC > 0.95) show high reliability of repeated skinfolds measurements [13, 14]. Percent fat (PF) was estimated by means Doxacurium chloride of the formula for white postpubescent and adult males [15], which takes into consideration the thickness of triceps skinfolds and the inferior angle of scapula. BMI and body composition indices, such as fat-free mass index (FFMI) and fat mass index (FMI) were calculated [16]. Biometrical measurements, Wingate tests for anaerobic capacity (ICC for relative peak power was 0.85 and typical error = 0.31 W·kg-1) and graded exercise for aerobic power were repeated twice in the athletes

who were during preparation period. The subjects also performed the special judo fitness test, SJFT [11]. The time interval between the measurements 1 and 2 amounted to 6 weeks. Characteristics of the training aimed at preparation for the second half of the annual training cycle The contestants have been training for approximately 20 hours a week: 5 days for 2 two-hour-training session. During the first stage, in the beginning of the preparation period, the contestants participated in a two-week training camp which was aimed at base training before special judo training regimes and competitive seasons were started. The physical exercise was aimed at the development of endurance by means of continuous training and interval methods in the form of running and rowing. Strength training was dominated by the exercises with partners which were based on repetitions.
