Recovery of previously mastered techniques in a shift from classical to beach volleyball by means of biomechanical analysis: (on the example of an attack spike)

The paper summarizes the results of study on the recovery of previously mastered skills of attack motions when transferring from classical to beach volleyball by means of biomechanical analysis. The purpose of the study was to evaluate advantages of the implementation of biomechanical analysis in the recovery of previously mastered techniques in beach volleyball. Comparison of the efficiency of the recovery of previously mastered techniques was studied on the example of the attack spike. Twelve male university team players participated in this study (age: 20.5 ± 0.72 years; body mass: 79.8± 7.6 kg; height: 186.7 ± 5.49 cm) were divided into experimental group (EG) and control group (CG). Personal spike profiles for beach volleyball were used in the experimental group to guide the technique recovery. The spike efficiency was assessed on three most informative parameters: initial ball velocity, hitting the court and hitting the assigned zone. The generalized value of spike efficiency was calculated as the parameters average. The results showed substantial acceleration of skill recovery to the previously archived level both in in seasonal shifts of the experimental group and after the constrained layoffs due to COVID-19 restrictions.
