RELATIONS BETWEEN THE PARAMETERS OF EXTERNAL LOAD IN BASKETBALL GAME SIMULATING EXERCISES OF VARIOUS TECHNICAL-TACTICAL TASKS

The aim of the research was determining the differences, similarities and relations between time, distance and maximum speed occurring in the structure of exercises – small games. While selecting exercises, the assumption was to maintain similar internal load with various technical-tactical assumptions assessed with the help of parameters generated with the use of GPS and IMU technologies. Twelve basketball players took part in the research (age 24 ± 4.7 years; height 187.9 ± 5.2 cm; weight 83.9 ± 8.7 kg). 3 exercises simulating match conditions, and intervals between them lasted 5 minutes. The players played as long as one of the teams scored 25 points. The ranges of IMU like acceleration or deceleration were divided into I-VIII zones from the value of -8 to 8 m/s/s. To examine differences in total distance and total effort among three exercises, we performed repeated ANOVA measures. This test was statistically significant at alpha (ρ ≤ 0.05). The maximum speed and the longest distance were registered in Exercise. 1 and equalled 23.22 ± 1.73 km/h and 1097.75 ± 48.11 respectively. The longest distance covered in 1 minute was registered in Exercise 2 – 66.10 ± 5.72 m/m. For bands II to VII, there were significant differences between Exercise 3 and Exercise 1 and 2. The correlations between Exercise 2 and 3 in bands III,VII was statistically relevant. Training time aiming at reaching the same external load should be modified and not dependent on score results. Changeable time conditions result in the lack of load stability in a given exercise, hence its unpredictability as to the planned training load. The results of this research shall help coaches apply, in the right moment of a training cycle, tasks simulating match conditions of particular running load, controlling in this way a type of tiredness and its level.
