Background: The purpose of this study was to examine the effect of a cognitive task on jump-landing biomechanics and performance. Methods: 26 recreational athletes participated in the study. Participants jumped forward off of a 30cm box a distance equal to one half of their body height, then immediately performed a countermovement jump. This movement was performed in a control condition, while ...
Objective: The aim of this research was making comparison between landing kinematics parameters at different minutes of simulated soccer game Methods: 15 soccer players from youth team of Sanay Mes of kerman voluntarily participated in this study who had records (2 years) in Premier League of Iran. They were at age (17.551.12) and weight (62.217.22). The players did Bangsbo fatigue protocol, ...
BACKGROUND Anterior cruciate ligament injuries are common in athletes and have serious sequelae. A valid clinical tool that reliably identifies individuals at an increased risk for ACL injury would be highly useful for screening sports teams, because individuals identified as "high-risk" could then be provided with intensive prevention programs. HYPOTHESIS A clinical screening tool (the Landi...
Background and Aims: The accurate mechanisms of ankle instability cannot be assessed in the absence of reliable knowledge about ground reaction force (GRF) variables. The purpose of this study was to evaluate the test-retest reliability of GRF variables during forward and lateral jump-landing in volleyball players with functional ankle instability (FAI). Methods: Eighteen professional volle...
Abstract The present review deals with the current scientific knowledge related ski jump landing. A specific focus is given on landing biomechanics, methods utilized for its analysis and injuries connected to phase. Despite demonstrated importance safety performance of jumpers, preparation are rarely investigated. In this paper, after having firstly described execution reason why important anal...
OBJECTIVES To investigate the effect of bracing and taping on selected electromyographic, kinematic, and kinetic variables when landing from a jump. METHODS Fifteen netball players performed a jump, so as to land on their dominant limb on a force plate. Electromyographic activity was recorded from the gastrocnemius, tibialis anterior, and peroneus longus muscles. Subjects were also filmed and...
BACKGROUND Females with history of anterior cruciate ligament (ACL) injury and subsequent ligament reconstruction are at high risk for future ACL injury. Fatigue may influence the increased risk of future injury in females by altering lower extremity biomechanics and postural control. HYPOTHESIS Fatigue will promote lower extremity biomechanics and postural control deficits associated with AC...
Objectives—To investigate the eVect of bracing and taping on selected electromyographic, kinematic, and kinetic variables when landing from a jump. Methods—Fifteen netball players performed a jump, so as to land on their dominant limb on a force plate. Electromyographic activity was recorded from the gastrocnemius, tibialis anterior, and peroneus longus muscles. Subjects were also filmed and me...
purpose: this study aimed to examine the differences in the co-activation of the rectus femoris (rf) and biceps femoris (bf) using the co-contraction index (ci) in aquatic and land environments during a drop-landing task in active and non-active females. methods: in this casual-comparison study, 10 active and 10 non-active females volunteered to participate. the ci was calculated from recorded ...
Snowboard jump landings represent an important topic of study within the area of sports biomechanics. This is due to the high risk nature of this activity and the potential to modify this risk through equipment design and skill development. This paper presents a summary of a comprehensive series of experiments designed to quantify landing biomechanics and the influence of external factors on th...
