Clearly defined objective. two. Inclusion of individuals consecutively. three. Info collected retrospectively. four. Assessments adjusted to objective. 5. Evaluations carried out within a neutral way. six. Follow-up phase constant with all the objective. 7. Dropout rate for the duration of follow-up much less than 5 . eight.

Results from the Research Table three presents the qualities in the research concerning their sample size, their age on the sample, their duration, at the same time as instruction duration, internal and external measures, and instruments made use of. In the eight research included, the study of Hannon et al. was the only to analyze the categories of under12 (U12), U13 [21]. Two research analyzed U14 category [21,25]. 4 research analyzed U15 category [18,20,21,24]. Two studies analyzed the category of U16 [21,25]. Three research analyzed the category of U17 [18,23,24]. Two research analyzed the category of U18 [21,25]. Lastly, 3 studies analyzed the category of U19 [18,22,24].Table three.
