Abstract
Background and Objective: In today’s professional world of refereeing, besides having specialized skills, capabilities, and personality traits, appropriate physical performance is one of the effective factors in sports advancement. The aim of the present study was to investigate the relationship between physical fitness and cardiac waves in volleyball referees.
Materials and Methods:
In this quasi-experimental comparative study, 60 volleyball referees from the national secondary school competitions for boys and girls (year 1402) were selected as the statistical sample. On the first day of the competitions, after the opening session, the research process, along with the benefits and strengths of participation, was explained to all referees in a predetermined meeting, and volunteer registration was conducted. On the following day, demographic questionnaires were first distributed among the volunteer referees, collected after completion, and then cardiac waves were measured using an electrocardiogram device. Additionally, to assess physical fitness, the factors of flexibility, muscular endurance, body mass index (BMI), and waist-to-hip ratio were measured. For inferential data analysis, Pearson’s correlation coefficient test was used (P ≤ 0.05).
Results:
There was a significant correlation between the P wave and flexibility (P = 0.02) and waist-to-hip ratio (P = 0.01); between the PQ interval and flexibility (P = 0.01) and muscular endurance (P = 0.004); and between the QT interval and muscular endurance (P = 0.02).
Discussion:
It appears that in volleyball referees, with improved physical fitness, cardiac function also improves.
