Abstract

Purpose: To evaluate the relationship between specific aspects of core stability and knee injury risk factors during drop-jump (DJ) landing.Methods: Eighteen college-aged male amateur basketball players participated in the project. Kinetic and kinematic data for DJ tasks were collected with force plates and infrared cameras. Raw data were processed to calculate knee joint angles and joint moments during DJ landing. Different components of core stability were represented by the sit-ups in 20 s (SU), trunk extensor endurance, trunk flexion and extension range of motion, dominant extremity single-leg stance time (DLS), and dominant extremity single-leg hop distance, respectively.Methods: Correlation and regression were used to determine the relationship between jumping-related biomechanical parameters and core stability components.Results: SU shared significant variance with the peak moment of knee extension (PMKE, p < 0.05), the peak moment of knee abduction (PMKA, p < 0.05), and the angle of knee internal rotation at initial contact (AKRI, p < 0.05). DLS shared significant variance with the angular motion of knee internal rotation (AMKR, p < 0.05) and the AKRI (p < 0.01). SU and DLS together could explain 52% of the variance observed in the AKRI, and the result was significant.Conclusion: Core stability’s strength and motor control aspects played an essential role in preventing knee injury during DJ landing. An integrative training program addressing core strength and motor control could be considered for coaches and athletes to prevent knee injury through core training and conditioning.

Highlights

Landing is a frequent movement in basketball, volleyball, etc., which need to jump frequently (Dufek, 1991; Vander Does et al, 2016)
The high and sudden ground reaction forces produced by landings translate into large external torques at the knee that can lead to soft tissues injury, especially for ACL injury (Bates et al, 2013; Padua et al, 2015). 45% of the knee injuries of basketball and volleyball players occur when they land after takeoff (Vander Does et al, 2016)
The results indicated that sit-ups in 20 s (SU) shared significant variance with the PMKE, PMKA, and AKRI

Summary

Introduction

Landing is a frequent movement in basketball, volleyball, etc., which need to jump frequently (Dufek, 1991; Vander Does et al, 2016). Previous research has studied the relationship between knee biomechanics during landing and knee injuries (Hewett et al, 2005; Della Villa et al, 2020). The research of Hewett et al (2005) demonstrated that knee abduction angles and moments were the primary predictors of ACL injury risk. Increased abduction angles and moments on the knee can increase anterior tibial translation and loads on the ACL several-fold and lead to injury (Della Villa et al, 2020). Incorrect positioning of the knee during landing could generate an additional load on the knee and lead to injury (Nguyen et al, 2015; Della Villa et al, 2020)
