Sažetak
INTRODUCTION: The way of determing the training int ensity zones in a particular sport is often a sourc e of problems in sports coaching. Since intensity zones form are the basis of optimal programming training, they definitely need to take a higher dose of attention. For that reason, the goal of the research was to examine the differences in training intensity zones establishe d experimentally and theoretically. METHODS: The sample consisted of 21 Croatian elite soccer players (Age = 18, 9±1, 41y ; H = 181, 4 ± 7, 06 cm ; W = 74, 6 ± 8, 14 kg). All sub- jects performed an incremental treadmill test (1 km /h per minute, 1.5% grade). Upper limits of trainin g intensity zones were determined by V - slope method which have been attributed to the corresponding heart rate (HRexp) and then, compared to the zones determined by algorithms of the percentage of the maximum heart r ate (%HRmax). The model that was used consisted of the four training intensity zones: recovery zone (RZ), the zone of extensive ae robic training (AEZ), the zone of intensive aerobic training (AIZ) and the zone of anaer- obic treshold (ANZ). The ANOVA and the Bonferoni we re used to determine differences in observed variab les. RESULTS:By analyzing the data we obtained statistically significant differen ces (p>0.05) in RZ (HRexp= 127, 19 ± 11, 6 bpm ; %HRma x= 114, 66 ± 5, 3) and in AEZ (HRexp= 152, 67±10, 3 bpm and % HRmax= 142, 75±5, 1 bpm ). In AIZ (HRexp= 164, 85±8, 4 bpm ; %HRmax= 161, 73 ± 5, 8 bpm) and ANZ (HRexp= 172, 46±7, 7 bpm ; %HRmax= 171, 3±6, 1 bpm) were no statistically significant differences. DISCUSSI ON:In comparison with experi- mentally determined zones, proposed algorithms of p ercentages of HRmax in the first two zones are too low. It can be attributed to the lack of attention giving zones with a light load, a lthough they may be substantial in a variety of tra ining programs. Furthermore, assess- ment of HRmax can be unreliable due to various intr insic and extrinsic factors if it is not measured w ith appropriate test. In the last two zones is not necessary doing significant changes in determining the percentage of HRmax. CONCLUSION: A nalysis has shown that the proposed percentages are miscalculated. Therefore t he authors recommend raising the values, concretely , in the RZ for 5 % (from 60 % to 65 % HRmax) and in the AEZ for 5 % likewise (fro m 60 - 75 % to 65 - 80 % HRmax). In AIZ the range i s 65 - 80 % HRmax and in the ANZ is 65 - 80 % HRmax.
