BACKGROUND: after a @entity130 or post surgical orthopedic, the loss of skeletal muscle strength is common. In addition to strength training schemes and/or resistance to treatment, it has been proposed as an additional treatment, the use of some @entity1522 such as @entity3264 ( @entity7647 ) in isolation or combination with other nutrients. However, the information on the effectiveness of oral @entity7647 supplementation during exercise strength schemes and / or endurance in adults with strength deficit is inconsistent. OBJECTIVE: to evaluate the strength of the evidence at hand about the effect of oral supplementation on muscle strength @entity7647 set to strength training schemes and / or resistance in adult muscle strength deficit. METHODS: a systematic search was conducted in different databases, in clinical trials reported from the year 1980-2014, both in English and Spanish, about oral @entity7647 supplementation alone or in combination with other nutrients, with a control group, in adults with strength deficits under exercise schemes of strength and / or endurance, tracking under a year and muscle power as the primary outcome. RESULTS: of 661 articles, six relevant studies were identified. The study @entity1 in @entity7647 isolation evaluation did not suggest changes between the groups, only an improvement in the perception of @entity425 . Studies evaluating @entity7647 with other nutrients, have reported results in favor of it. No meta-analysis was possible. CONCLUSIONS: nowadays there are insufficient data on the effects related to the @entity7647 on the deficit of muscular force during exercise schemes in adults. It is required more research in this topic to respond more accurately about this fact.
