Abstract

Background: Throwing velocity is one of the determinant scoring elements in handball. However, our knowledge of anthropometric factors and shoulder muscle strength among female players and how these affect throwing velocity is limited. Objective: This study aimed to assess the relationships between throwing velocity and the physical traits of anthropometric factors and shoulder muscle strength in female handball players. Methods: Nine elite female junior handball players (age 17.1 ± 1.7 years, body height 169.7 ± 3.8 cm, body mass 66.2 ± 6.8 kg, experience with handball 8.9 ± 1.7 years) participated in the study. Spearman's correlation coefficient was used to detect correlations between throwing velocity and shoulder internal rotator torque, explosive strength deficit, and anthropometric parameters of the upper limb. Results: Our results showed significant correlations between throwing velocity and upper limb length (r = .82) and hand length (r = .68); however, no significant correlations were observed between throwing velocity and shoulder internal rotator peak torque, explosive strength deficit, lean body mass of upper limb, and other anthropometric parameters. Conclusions: The results of this study suggest that the lengths of the upper limb and hand are the two main elements that affect throwing velocity in female handball players; this could be employed in talent identification.

Highlights

Over-arm throwing ability is an essential element of success in various sports associated with frequent overhead actions
Lean body mass of upper limb had no significant correlation with throwing velocity
The principal objective of this study was to assess the relationship between throwing velocity and the physical traits of anthropometric features and shoulder internal rotators (IR) strength of handball players to evaluate the contribution of these factors to throwing performance

Summary

Introduction

Over-arm throwing ability is an essential element of success in various sports associated with frequent overhead actions. Concerning the cocking phase, the shoulder internal rotators (IR) benefit from a stretch-shortening cycle in an eccentric motion followed by concentric muscle contraction, which directly affects the throwing velocity in the acceleration phase. Our knowledge of anthropometric factors and shoulder muscle strength among female players and how these affect throwing velocity is limited. Objective: This study aimed to assess the relationships between throwing velocity and the physical traits of anthropometric factors and shoulder muscle strength in female handball players. Spearman’s correlation coefficient was used to detect correlations between throwing velocity and shoulder internal rotator torque, explosive strength deficit, and anthropometric parameters of the upper limb. Conclusions: The results of this study suggest that the lengths of the upper limb and hand are the two main elements that affect throwing velocity in female handball players; this could be employed in talent identification
