SIGNIFICANCE OF SPEED TESTS WITH MAXIMAL AND SUBMAXIMAL INTENSITY REFERRED TO ANAEROBIC CAPACITY IN ADOLESCENT VOLLEYBALL PLAYERS

ABSTRACT One of the major problems in strength and conditioning of volleyball is connected with development and control of the anaerobic capacity. At this point, the aim of the study is to research the significance and the possibility of evaluating the speed test that characterizes anaerobic capacity in volleyball. The tasks of the research are: To establish a correlation between speed tests with maximal and submaximal intensity; To determine the relationship between indicator that characterizes anaerobic capacity and speed abilities. The study group was 19 female volleyball players of the under-18 national team of Bulgaria. Methods: To determine the anaerobic capacity and the indicators that characterize it we used the Wingate laboratory test and anthropometric indicators. Field tests were measured through chronometry. The results of the test were further analyzed by statistical methods. Results: The data from the descriptive statistics define the study group as homogeneous. Variation coefficient vary from 3.47% to 17,85%. This is a reason to assume that the received correlation results would be reliable enough. The research identified a high correlation between the speed tests with maximal intensity and the two types of test with submaximal intensity (r = .714; r = .732) but the high and significant correlation between the height of the subjects and the shuttle running type 1 (r = .714) were basis to recommend implementation of the shuttle running type 2 as a field test that characterizes anaerobic abilities in female volleyball players. A negative correlation between the results in sprint tests and the Wingate test determined that better results of speed tests correspond to: higher relative minimal power; smaller power decrement and coefficient of fatigue. At the same, time moderate correlation between results in speed tests and peak power and a negative moderate correlation between speed tests and relative peak power could be interpreted as underdeveloped anaerobic capacity.
