The effects of ankle barcing to the volleyball players performance

Abstract

Volleyball is characterized by short and quick movements. The repetitive jumping and side-to-side movements required in volleyball increase the risk of injuries to the foot and ankle. Ankle injuries, particularly sprains, are the most common injuries sustained in volleyball. Ankle bracing used extensively to enhance ankle joint stability, prevent injury occurrence, and mitigate severity. Ankle braces are not mandatory in volleyball but it commonly used during the rehabilitation period after ankle sprains by the players for a long time. There are some adverse effects of bracing. Pressure to the muscles surrounding the joint can result additional damage such as muscle weakness. Muscle weakness can impair athletic performance can decrease jumping height. We measured and compared vertical jump height on braced and unbraced conditions. The results showed that, the tallest jump, less time for jumping and maximal force impulse were accounted for the unbraced condition.
