(6) CORRELATION BETWEEN VERTICAL JUMP TESTS AND ANAEROBIC POWER IN PROFESSIONAL FUTSAL ATHLETES IN START OF THE CONDITIONING PERIOD

Purpose: To verify if there are correlations between performance in vertical jump tests and anaerobic power of professional futsal athletes at the beginning of the season. 

Methods: This research had as a sample 13 adult athletes, male, Futsal professionals with 26.69±3.84 years of age and body mass (BM) of 78.85±12.40 (Kg), who play in a club professional from Rio de Janeiro, Brazil. Data were collected on only one visit to the training center. Initially, the BM was measured and then the selected jump tests ^2,3 squat jump (SJ) were performed, where the athletes started from the squat position with the hips and knee flexed at approximately 90°, after remaining 2 seconds in that position, without any countermovement, the athletes performed the jump. Countermovement jump (CMJ) the athletes started from the standing position, performed the squat and without any interruption they did the vertical jump, in both tests the athletes were asked to remain with their hands on their waists, while Abalakov Jump Test (AJ) the athletes performed the same procedures as the CMJ, but with the help of the upper limbs during the movement. Jumps were measured using the VERT Jump monitor, which was positioned close to the iliac crest and has valid conditions for measuring jump height⁴. In the intermittent yo-yo recovery test level 1 (YIR1)⁵ the athletes performed 2 repeated runs of 20 m, each back and forth between the start and finish lines at a progressively increasing speed controlled by audio beeps from a recorder. All athletes performed the tests on the same training and game court and the order of the tests was the same for all.

Results: The following results were obtained: Squat Jump Test (SJ) 44.84±5.17 (cm); Countermovement Jump Test (CMJ) 48.53±6.50 (cm); Abalakov Jump Test (AJ) 53.06±7.28 (cm); VO2max 46.78±3.30 ml(kg.min). Pearson correlation⁶ has determined that there are high positive correlation between SJ and CMJ and moderate positive between AJ and CMJ and AJ and SJ.

Conclusions: The results of the study with professional male futsal athletes did not identify a correlation between jump performance and VO2max, showing that for the participants, VO2max is independent of the muscle power of the lower limbs. Being a preliminary study carried out at the beginning of the season, the monitoring of these variables with the training throughout the season that the athletes will do can modify this relationship. PRACTICAL APPLICATIONS: With the results of this research, coaches can organize the training of athletes, in this case intensifying speed training in intervals and associated with jump training.
