A comparative study of match load between tennis players with high and intermediate ITN performance levels.

Abstract

Background: Advancements in player tracking technology have significantly enhanced the monitoring of tennis in real-match conditions. This study aims to compare the differences in physical performance and match load of tennis players at different levels during matches using wearable devices.

Methods: A cross-sectional design was used to monitor match load and physiological parameters in tennis players of varying performance levels via smart wearable devices. Participants were divided into high- and intermediate-performance groups based on the International Tennis Number (ITN). Key metrics such as acceleration, deceleration, movement speed, player load, and change-of-direction frequency were recorded. Independent sample t-tests and effect sizes were calculated to compare the groups.

Results: Findings revealed that the high-performance group had substantially higher duration in the 0-60% HRmax range (P<0.05, ES: 1.57). The intermediate group demonstrated greater values in physical performance metrics (P<0.05, ES: 0.22-1.00) and displayed greater numbers and distances in acceleration/deceleration (P<0.05, ES: 0.59-1.12).

Conclusions: These results suggest that the high-performance group prioritizes strategic resource utilization over physical exertion. The study highlights notable differences in physical performance and match load among tennis players of varying levels, underscoring the value of automatic tracking technology in enhancing players training and performance capabilities.
