# Sex Differences in Jump Capacity and Elastic Index in Table Tennis Players

## TL;DR

This study compares jump performance and limb elasticity in male and female table tennis players, finding sex-based differences in explosive strength and elasticity.

## Contribution

The study provides new insights into sex-specific differences in jump capacity and elastic index among young table tennis players.

## Key findings

- Male players outperformed females in vertical and horizontal jump capacities.
- Female players showed better elastic index values compared to males.
- Significant limb asymmetry was observed in both male and female players.

## Abstract

Background/Aims: Table tennis performance is influenced by various factors such as technique, tactics, and fitness. Additionally, many shots are executed at high speeds, developing significant levels of explosive strength in the lower extremities. This study aimed to assess the jump capacity and the elasticity index of the lower limbs among young table tennis players based on sex. Additionally, this study assessed leg asymmetries between the dominant and non-dominant limbs during jump tests. Methods: A total of 40 players (20 boys and 20 girls), aged 16–18 years, participated in the study. Vertical countermovement jump, squat jump, and horizontal jump tests were conducted to evaluate both vertical and horizontal jumping capacities, as well as leg asymmetries between the dominant and non-dominant limbs. Results: Differences were observed in both vertical and horizontal jumps, with male players achieving better results in all jumping capacities. However, female players obtained better values in elastic index. Additionally, significant differences were found between dominant and non-dominant legs in both male and female players. Conclusions: Considering that explosive strength is one of the most essential physical capacities in this sport, this information could prove valuable for talent identification, the design of training programs, and the optimization of physical performance monitoring systems in table tennis.
