Abstract
Objectives Lawn tennis is an explosive sport that involves various fitness parameters such as
explosive strength, endurance, power, and agility. Improved physical fitness leads
to superior athletic performance. The coach's perception is contingent upon his perception
of the player at the time the athlete is comparing himself to the coach. Thus, this
study aimed to determine the association between chosen fitness factors and perceived
performance by coach in lawn tennis players. Thus, the study aims to detect the relationship
between different fitness variables and perceived level of performance in lawn tennis
player.
Materials and Methods Fifty-two lawn tennis players from two sports academies were measured for various
parameters of fitness and perceived performance level as rated by the coach.
Statistical Analysis The association between selected fitness metrics and perceived performance in lawn
tennis players was investigated using Pearson's correlation test. Furthermore, the
data were analyzed with paired t-test for male and female group, and ANOVA was used to analyze the difference between
the levels of performance.
Results Fatigue index, closed kinetic chain upper extremity stability (CKCUEST) test, and
peak power and energy expenditure taken by metabolic equivalent (MET) calculation
was found to be statistically different between males and females. While comparing
BMI with the peak power, there was a weak positive correlation for males, while for
female there was no correlation. Metabolic equivalent, energy expenditure, and peak
power were positively correlated with the level of performance; however, fatigue index
and level of performance had a negative nonsignificant correlation.
Conclusion Peak power, fatigue index, energy expenditure, and BMI were found to be associated
in males, but not in females. Peak power and energy expenditure were connected to
performance in both genders.
