Variables Associated with the Effectiveness of Ball Possession in At-Home Futsal Matches.

This study aims to identify contextual situations (score, game time, the interaction between teammates and opponents, start and restart plays) that increase the odds ratio of maintenance of ball possession and scoring a goal. Twenty professional futsal players were evaluated in seven home official matches. The games were filmed to analyze the offensive actions.

Venous versus capillary sampling for total creatine kinase assay: Effects of a simulated football match.

Background: Capillary rather than venipuncture may be a simpler and less invasive blood collection protocol that would increase the number of potential sampling tests. However, if capillary sampling can be used as an alternative to venipuncture to determine changes in plasma, total creatine kinase (CK) activity in response to a football training session is poorly known.

Objective: This study aims to determine whether capillary blood sampling would provide representative measures of total CK activity compared to venipuncture in response to a football training session-induced elevated CK plasma levels.
