The Effect of Combined and Core Stability Training Program with Protective Measures on Selected Variables of Physical Fitness of Junior and Young Volleyball Players during the Coronavirus Pandemic

Abstract

Objective This study aimed to investigate the effect of a combined and core stability training program with protective measures on selected variables of physical fitness of junior and young volleyball players during the coronavirus pandemic. Methods Fifteen male volleyball players [18±1.06 y] after the end of the first quarantine period and then after 12 weeks of combined and core stability training program emphasizing physical fitness exercises in compliance with all health protocols, as pre-test and post-test of selected key factors, performed physical fitness including lower limb strength, upper limb, and abdomen endurance, as well as flexibility tests. Descriptive statistics, the Shapiro-Wilk test, and paired t-test were used for statistical analysis (P≤0.05). Results The present study results showed a statistically significant difference in the variables of upper limb and trunk muscle endurance and muscle flexibility, but in the lower limb strength variable, this difference was not observed in both pre-test and post-test levels. Conclusion Volleyball coaches and players can benefit from combination and core stability training with health protocols to maintain and improve fitness during the coronavirus epidemic.
