摘要：The aim of the study was to compare the results obtained in the coaching tests (block jump and spike jump) with the results of laboratory tests (counter-movement jump and spike jump performed on force plate) in volleyball players. The study involved 16 volleyball players. Characteristics of participants: age 17.2 ± 0.7 years, body height 196.2 ± 7.6 cm, body mass 86.4 ± 10.0 kg, training experience of 7.8 ± 1.6 years. Each volleyball player performed coaching test consisting of three block jumps and three spike jumps, and laboratory test consisting of three counter-movement jump (CMJ) and three spike jump (SPJ) performed on force plate. The mean values obtained by the competitors in the coaching test were: height in block jump 47.6±5.2 cm, height in spike jump 72.4±7.6 cm, and laboratory test: the height of rise of the body’s centre of mass in the CMJ 47.9±4.0 cm and SPJ 60.8 ±5.7 cm. Significant differences were found between height in spike jump and the height of rise of the body’s centre of mass in the SPJ. Significant relationship were found between the height of jump obtained during laboratory and coaching tests. In conclusion, height of jump in CMJ measured in coaching test doesn’t differ from the height of rise of the body’s centre of mass measured in SPJ jump on force plate (laboratory tests).
