Peculiarities in intensity of physical loads of 12-13 years old boys basketball players

Importance of the research. Heart rate per minute is objective and informative index of physical intensity (Velenksy et al., 1987; Velensky, 1999; Buceta, 2000; Papadopoulos et al., 2002; Balčiūnas & Stonkus, 2003; Filho et al., 2003; McKeag, 2003;Petridis et al., 2004; Matthew & Delextrat, 2009; Ziv & Lidor, 2009; Abdelkrim et al., 2010; Castagna et. al., 2011). Heart rate evaluates the intensity and can be measured frequently and at present (Westerterp, 2009). Basketballers' physical load, reaction to the load are being analysed on frequent basis however there are not many basketball game researches on the boys between 12 and 16 years (Beam & Merrill, 1994; Rodriquez & Alonso et al., 2003). Research hypothesis: physical load intensity of specific basketball training is adequate to the intensity of training. Research problem: in order to achieve the physical fitness of junior basketball players, it is vital to apply physical loads which are adequate to the intensity of the physical loads in the game. Research object: intensity of junior basketball players‘ physical loads. Research aim is to estimate the peculiarities of physical loads intensity of junior basketball players (of 12-13 years old) during the training and in the game. Research objectives: 1. to estimate the dominant loads in the game and training of junior basketball players. 2. to estimate peculiarities of players‘ biological load values during training and in the game. Conclusion: 1. Intensity of physical loads modeled during the every-day and training sessions varied in the middle and intensive zones. During the entire game intensity was little or middle. However, during the active practice sub-maximal intensity took place. 2. During the entire game, despite its result the amount of heart rate was bigger than during the active practice and during the training. The sum of conditional unit corresponded to the HR values of the indice
