Resumo
The aim of this study was to examine the efficacy of creatine supplementation
associated with resistance training on lean mass, strength and bone mass in the
elderly. This was a 12-week, parallel-group, double-blind, randomized, placebocontrolled
trial. The individuals were randomly allocated into one of the following
groups: placebo plus resistance training (PL + RT) and creatine supplementation
plus resistance training (CR + RT). The participants were assessed at baseline and
after 12 weeks. The primary outcomes were lean mass and strength, assessed by
dual energy X-ray absorptiometry (DXA) and ten-repetition maximal (10RM) tests,
respectively. Secondary outcomes included lumbar spine, right and left femoral neck,
dual femur and whole body bone mineral density and whole body bone mineral
content, assessed by DXA. The CR+RT group had superior gain in lean mass when
compared with the PL+RT group (p = 0.02). Changes in 10RM tests in bench press
and leg press exercises, body composition, bone mineral density and content of all
assessed sites did not significantly differ between the groups (p > 0.05). In
conclusion, 12 weeks of creatine supplementation associated with resistance training
resulted in increased lean mass.
