“…So far in the literature, the authors have described significant differences between trained and untrained subjects [20], non-elite and elite athletes [8], subjects of different ages [17,18], or cadets, juniors and seniors [1,9]. The results of our study do not support the thesis that cadets, juniors and seniors differ from each other.…”

“…Nonetheless, motor training constitutes an important link of the training process. As proven by studies athletes who achieve the highest sports results are characterized by a similar level of fitness [4][5][6][7]. An essential element of rational motor training is diagnostics of its effects.…”

SummaryIntroduction. The main cognitive objective of the article was to compare muscular force moment values of extensors and flexors of the knee joint measured under static and isokinetic conditions in kickboxing and taekwondo athletes.Materials and methods. 28 female and male athletes who practice kickboxing and taekwondo ITF participated in the study. The study of muscular force moments was conducted using the Biodex System 4 Pro device. Measurements of muscular force moments of extensors and flexors of the knee joint under static and isokinetic conditions. Differences between the results were established using the Mann-Whitney U test, assuming p≤0.05 as the minimum significance level.Results. In the study of the peak value of the maximum muscular force moment of knee joint extensors of the dominant and non-dominant limbs, men practicing kickboxing achieved significantly higher values than taekwondo athletes (p<0.05). Similar relations were not observed in case of flexors. Asymmetry of knee joint extensors and the flexor-extensor relation were indicated in taekwondo athletes. Significant differences of the studied parameters were not observed in women. The study of muscular force moments measured under static conditions did not indicate any significant differences between the groups in any of the parameters.Conclusion. Kickboxing and taekwondo athletes were characterized by a similar structure of biomechanical parameters of lower limbs (differences concerned only isokinetic measurements in men). It may results from their training which is similar regarding their comprehensive and targeted preparation.

“…Maximum power output recorded in this study in the cadet judoists are similar and U23 judo athletes are higher than reported for karate athletes (11.67 ± 0.87 W · kg -1 ) [20]. The power output at external load of 7.5% BW obtained in ours study in the cadet judoists (10.71 ± 0.76 W · kg -1 ) are lower and U23 judo athletes (11.36 ± 0.51 W · kg -1 ) are higher than reported for cadet (15.5 ± 0.5 years old) and junior (17.5 ± 0.7 years old) Polish judoists (11.2 ± 0.5 W · kg -1 11.32 ± 0.7 W · kg -1 , respectively) by sterkowicz et al [5]. In our study, significant differences were founded between the cadet and U23 athletes only for absolute and relative power output at external load equal 12.5% BW and realative maximal power.…”

“…The measurement of the maximal static muscle torque and maximal power output of legs yields valuable information that can be extremely useful in judo training planning [3]. Professional literature includes a number of works comparing to the results of judoists with untrained [4][5][6], super elite with elite or elite with non-elite athletes [1,[7][8][9], female with male [6,10,11] and cadets, juniors and seniors [11][12][13]. Also, there is very little work comparing players at different stages of training [9,12,14].…”

Purpose. The aim of the study was to examine age differences in the maximal power and height of rise of the body mass centre measured in spike jump (sPJ) and counter-movement jump (CMJ), and power-velocity relationship of lower extremities between cadet and U23 age class judo athletes. Methods. seven cadets (age 16.6 ± 0.7 years) and eight U23 age class (21.3 ± 1.4 years) Polish judoists took part in the study. The maximal power and height of jump were measured at sPJ and CMJ jumps. Powervelocity relations (P-v) were determined from 5 maximal cycle ergometer exercise bouts at increasing external loads equal to 2.5, 5.0, 7.5, 10.0 and 12.5% of body weight (BW). Results. Cadet judoists had a significantly smaller maximal power output (11.56 ± 1.21 W · kg -1 ) than U23 athletes (12.69 ± 0.67 W · kg -1 ). The optimal velocity was similar in both group (119.3 ± 16.0 rpm and 119.6 ± 15.5 rpm, respectively). significant age differences were founded between the cadet and U23 athletes for power output at external load equal 12.5% BW. Cadet judoists generated insignificantly lower maximal power in CMJ and sPJ than U23 judo athletes with except of the absolute maximal power in sPJ. The age difference was observed in height of CMJ. Conclusions. Based on the characteristics of F-v curve we can see in which direction follow the effects of training. Application of CMJ and sPJ in jumping test allows to assess changes in neuromuscular coordination. The use of the both methods give better information to optimal training control.
