Abstract
INTRODUCTION:
Hop Tests (unipodal horizontal jumps) have been recommended as one of the reliable assessment tests when allowing a return to competition for a sportsperson after an anterior cruciate ligament injury1,2,3,4. Currently, comparison is made of the results with the contralateral limb through the symmetry index, a method which might not provide sufficient security upon the return to competitive sport5. Hop tests can be used in preseason to gain reference values prior to a possible injury.
OBJECTIVES:
The objective of this review is to analise the scientific literature such as the F-Marc6 (reference manual of FIFA) to confirm whether include said tests in preseason for football teams.
METHODOLOGY:
A search was conducted in the Pubmed y Cochrane databases (17/04/17) with the search terms “Hop Test”, “Football”, “Soccer”, and “Preseason”. Articles in English and Spanish were both accepted. Articles excluded were those that did not make reference to the knee, to football, and those that did not conduct tests during preseason. From a total of 33 articles, 4 with these search criteria were included, 5 articles were added trough the bibliography of other studies, and the F-Marc manual was analised.
RESULTS:
4 of the articles used the hop tests in preseason for some type of study, of which 3 were used as part of a prospective assessment for the season. On the other hand, the F-Marc does not consider Hop Tests as an assessment test.
CONCLUSIONS:
Hop tests were not found to be used in preseason as reference values prior to possible future injuries, data which could be beneficial for a safe return to sport.
