Changes in Drop-Jump Landing Biomechanics During Prolonged Intermittent Exercise
BACKGROUND As injury rates rise in the later stages of sporting activities, a better understanding of lower extremity biomechanics in the later phases of gamelike situations may improve training and injury prevention programs. HYPOTHESIS Lower extremity biomechanics of a drop-jump task (extracted from a principal components analysis) would reveal factors associated with risk of anterior cruci...
متن کاملEffects of gender and foot-landing techniques on lower extremity kinematics during drop-jump landings.
The purpose of this study was to assess kinematic lower extremity motion patterns (hip flexion, knee flexion, knee valgus, and ankle dorsiflexion) during various foot-landing techniques (self-preferred, forefoot, and rear foot) between genders. 3-D kinematics were collected on 50 (25 male and 25 female) college-age recreational athletes selected from a sample of convenience. Separate repeated-m...
متن کاملRunning backwards: soft landing-hard takeoff, a less efficient rebound.
Human running at low and intermediate speeds is characterized by a greater average force exerted after 'landing', when muscle-tendon units are stretched ('hard landing'), and a lower average force exerted before 'takeoff', when muscle-tendon units shorten ('soft takeoff'). This landing-takeoff asymmetry is consistent with the force-velocity relation of the 'motor' (i.e. with the basic property ...
متن کاملEffectiveness of Joint Stiffness and Power Alternations in Different Shoe Insole Hardness on Injury Prevention During Jump-Landing
Background: Studies on how the shoe insole hardness regulate joint stiffness and transfer energy in the lower extremity during jump landing are scarce. The current study aimed to determine the effectiveness of shoe insole changes in joint power and stiffness during landing from jumps. Methods: Fifteen healthy male athletes volunteered to perform jump-landing in various shoe insole conditions. ...
متن کاملreliability of knee kinematic parameters during drop jump landing in healthy male subjects
introduction: knee joint has the highest percentage of injuries among lower extremity joints especially in athletes and people with high activity levels. therefore, analyzing of knee movements has an important area of research in the bioengineering and rehabilitation fields. sharif human movement instrumentation system (sharif-hmis) is a new inertial sensor designed for movement analysis. the p...
