BACKGROUND Cryotherapy, in the form of ice massge is used to reduce inflammation after acute musculoskeletal injury or trauma. The potential negative effects of ice massage on proprioception are unknown, despite equivocal evidence supporting its effectiveness. OBJECTIVES The purpose of the study was to test the influence of cooling on weight discrimination ability and hence the performance in...

The purposes of this study were to assess unilateral and bilateral vertical jump performance characteristics, and to compare the vertical ground reaction force characteristics of the impulse and landing phase of a vertical jump between the dominant and non-dominant leg in soccer players. The sample consisted of 20 male soccer players (22.80 ± 2.71 years, 1.88 ± 0.06 m, 76.47 ± 8.80 kg) who comp...

Content: Electromyography (EMG) is a recording of muscles electrical activity and is useful for mechanism study. In Exercise and Sport Science, mechanism of dominance and non-dominance limb activity is recently a focus area. Objective: The aim of this study is to observe the muscle electrical activity of soccer players’ dominant and non-dominant leg. Design: Cross-sectional study. Setting: Dist...

To determine the effect of plant leg and approach condition on the torques of the hip, knee, and ankle in soccer kicking tasks, nine female collegiate soccer players performed a series of kicking tasks from three different approach conditions. Kinematic data of the hip, knee, and ankle were recorded and joint torques of the plant leg were calculated. Peak flexor torque of the hip and ankle was ...

INTRODUCTION: Landing is a common manoeuvre in sporting activities that can often lead to anterior cruciate ligament (ACL) injury with greater risk found in females [1]. Single-leg landing increases the risk of injury compared to double-leg landing because it is performed with less knee flexion and provides less stability. Although there has shown to be significant differences in maximum valgus...

One of the key components in sports injury prevention is the identification of imbalances in leg muscle strength. However, different leg muscle characteristics may occur in large playing area (field) sports and small playing area (court) sports, which should be considered in regular injury prevention assessment. This study examined the isokinetic hamstrings-to-quadriceps (H:Q) ratio and bilater...

The study investigates the effects of the 11+ and HarmoKnee injury prevention programmes on knee strength in male soccer players. Under-21-year-old players (n=36) were divided equally into: the 11+, HarmoKnee and control groups. The programmes were performed for 24 sessions (20-25 min each). The hamstrings and quadriceps strength were measured bilaterally at 60°·s(-1), 180°·s(-1) and 300°·s(-1)...

Between-leg strength differences can negatively influence sprint acceleration. The challenge is to find a method to measure this within a unilateral exercise. This study analyzed a five repetition-maximum (5RM) Bulgarian split-squat (BSS) to identify between-leg differences for the dominant and non-dominant legs in peak and mean power, force, and velocity as measured by a linear position transd...
