The effect of a novel movement strategy in decreasing ACL risk factors in female adolescent soccer players.

abstract：:The purpose of this study was to develop a novel, anaerobic efficiency test in swimming. The concept of this test was build upon the classic Wingate anaerobic test, with the difference that the dependent variables are extracted from an instantaneous speed curve.
