Wingate tests are the most frequently exercise tests used to evaluate their anaerobic capacity in relation to the metabolic changes, sexes, tested extremities and training status. Short tests durations (10-30 sec), pre test warm-up and loud verbal encouragement from a researcher ensure, that examined individuals do not use pacing strategy but engage their maximal physical abilities from the start to the end of the effort. An advanced technology of power measurements online with very high frequency (1000 Hz) allow to explore various internal and external circumstances affecting levels of the performance parameters, like power output, work output and accumulating fatigue during the test, that expresses itself as decrease of the power, especially at the end of an exertion. Peak power (PP) recorded during Wingate tests showed diag nostic value for predicting of strength, power levels and performances of other exertions. Changes in PP levels induced by period of strength and power ballistic exercises were related to performance of the other tests like high jumps and shot put throws [1]. It was found, that PP during bench throw ex plained 87% and 72% of the variances in arm crank Wingate peak power in men and woman respectively [2]. Another variable recorded during Wingate, which diagnostic value seems to be not appreciated is a time to PP attain (TA). When starting an anaerobic exercise test , an examined individual has to overcome not only braking force bat also wheel inertia, thus, maximal rate of revolutions he/she usually achieves at 2-4 seconds after the start. Obviously, the higher rate of force development, the shorter the TA, and this relationship ex plains, why rate of force development (so called explosive strength) affects performance of the various athletic exertions for in stance a high jump [3]. As the completing of the Wingate test engages anaerobic sources of energy, we may observe high rise of lactate level in blood after termination of that type of effort. Generally, the higher the LA the more intensive the effort. The main issue of the study on a post effort acidosis is to find the time point, when LA reaches its peak.

Introduction. Body worn accelerometry has been shown to be reliable in measuring training Intensity in several sports including MMA and has been used to assign training intensity in sports such as football and rugby, but not in MMA. Material and methods. Eight male MMA trained participants (age 25.5±4.5 yrs) were equipped with a Catapult Minimax x3 accelerometer between the T3 and T4 vertebrae and completed a series of MMA specific movements in isolation and a MMA sparring bout each (3 x 5 minute rounds). Mean playerload was recorded for each isolated movement and the equivalent movements in the sparring bouts. Results. Paired sample t tests (p≤0.05) found that jabs, crosses and left hooks had significantly higher playerload in isolation that in sparring, single leg takedowns have higher playerload than double leg takedowns in isolation but not in sparring, whilst takedowns cause significantly greater playerload than strikes in both isolation and sparring according to one way ANOVA (p≤0.05). It was also found that there is no difference in playerload between an unsuccessful takedown and a successful takedown in sparring, either for the offensive participant or the defensive participant. Conclusions. These results demonstrate the differences in movements in MMA AND can be used to more accurately prescribe training intensity.

Boxing and wrestling are these sports discipline, in which being assigned to a given weight class may determine the final results of athletes. Competition with an opponent belonging to a lower weight class potentially makes it possible to gain physical advantage, thus in combat sports pre-competition body weight reduction (BWR) is typically practiced, which in terms of its intensity may be defined as rapid weight loss (RWL) or gradual body weight reduction (GWR) [1-3]. In relation to the BWR volume it was shown that a considerable percentage of athletes reduce their body weight by 5-10%, while some respondents declared weight reduction of more than 10% [2-8], additionally starting the body weight reduction period as late as a week before the competition [2,9-10]. Litera ture sources describe such extreme cases as those when a week-long RWL amounted to as much as 18.1% [11], whe reas the first body weight reductions were already observed in children aged 5 years [12]. What is more, cases were also reported, in which RWL led to the death of the athlete [13-14]. However, it needs to be mentioned here that BWR might bring certain advantageous effects if it was executed in a rational manner [6,15]. Moreover, in a study by Pattersson et al. [4] it was found that pre-competition BWR is perceived by athletes as an important element in mental preparation for a fight, enhancing the feeling of control, commitment and thus selfassurance. Unfortunately, athletes frequently habitually adopt inappropriate BWR methods, involving e.g. fasting, limited fluid intake, long-term sauna sessions and training in impermeable clothing [1-2,5,9]. It seems that in many cases athletes are not aware that such a rapid body weight loss (RWL) results mainly from dehydration and reduced muscle and hepatic

Sports fight analysis is a common element of observation of players’ behavior during tournamen fights. It represents only a fraction of the research area, carried out by many other authors. Many researchers point to the relation between selected factors and fight results in taekwondo, they point out many factors, such as morphological [1,2,3], psychological [4], biomechanical [5,6,7,8] and physiological [9,10,11]. The dynamic development of martial arts in Western society is associated with a wide spectrum of their impact on phy sical and spiritual development. They are recommended for young people as exercise which may reduce aggression and anxiety, and improve their social behavior like respect for ethi cal standards. The fast development of the world’s Olympic Taekwondo began with the introduction this discipline to the program of the Olympic Games. In its Olympic form taekwondo fight is based on the rivalry of two players in a direct fight, relying mainly on a specific blow to the opponent. In the world the most often practiced Taekwondo dyscipline is Kyourugisports fight. In the past few years the specificity, regulations and a form of fighting has changed several times. There were created some regulations of sportsmanship, which determines all allowed body space to perform punches and blows. During the fight, the athlete performs many combinations composed of several elements such as kicks towards the head and trunk, the body punches, blocks, dodge, spinning and leaping varia tions. The refore, it was introduced to wear compulsory protectors of trunk, groin, head and limbs in order to increase the safety of players. In the fight of taekwondo competitors mainly leg techniques.
