Estou procurando evidências de que creatina suplementada
a idosos quando em programa de exercício resistidos,
traz aumento de massa muscular....se alguém dessa lista
tiver alguma referência, livro ou artigo a
indicar....estarei a espera....
Muito Obrigado pela atenção.... Prof. Mst. André Luis

Improvement of Cognitive Function by Mental and/or Individualized Aerobic
Training in Healthy Elderly Subjects.
Int J Sports Med 2002 Aug;23(6):415-21.
The aim of this study was to compare the effects of aerobic and mental
training on cognitive function and to determine if the association of the two
techniques shows better results. Thirty-two healthy elderly subjects (60 - 76
years) were assigned to one of four groups: aerobic training, mental training,
combined aerobic and mental training and a control group. All subjects took two
cognitive tests and an incremental exercise test before and after the training
period. The intensity of exercise was individualized at the heart rate
corresponding to the ventilatory threshold of each subject. After two months,
the control group showed no alteration in physiological and cognitive
variables. After the training period, the results showed a significant
improvement in Vdot;O 2 max (F = 4.45, DF = 1, p < 0.05) of 12 % and 11 % in
aerobic training and combined aerobic and mental training groups, respectively.
Logical memory (F = 4.31, DF = 1, p < 0.05), as well as paired associates
learning scores (F = 5.47, DF = 1, p < 0.05) and memory quotient (F = 6.52, DF
= 1, p < 0.01) were significantly improved in the three trained groups. The
mean difference in memory quotient between pre and post training was
significantly higher in the combined aerobic and mental training group compared
to aerobic training or mental training groups (F = 11.60, DF = 3, p < 0.001).
We conclude that the specific aerobic training and mental training used in this
study could induce the same degree of improvement in cognitive function and
that combined training seemed to lead to greater effects than either technique
alone.

A comparison of community-based resistance exercise and flexibility
exercise for seniors.
Aust J Physiother 2002;48(3):215-9.
Progressive resistance training has positive effects on the health of
elderly people, however exercise programs for seniors frequently focus on other
forms of exercise. This study is a randomised trial with a blinded assessor
comparing a community based progressive resistance training program (n = 20)
with a flexibility program (n = 20), both one hour twice weekly for 10 weeks.
Outcomes were strength, gait, balance and quality of life. Progressive
resistance training had a greater effect than flexibility training on right
sided quadriceps strength (mean difference between groups = 7.7%; 95% CI
3.6-11.8%, p < 0.003 MANOVA), left sided quadriceps strength (mean difference =
9.9%; 95% CI 5.6-14.2%, p < 0.003 MANOVA), left sided biceps strength (mean
difference = 15.2%; 95% CI 11.7-19.2%, p < 0.003 MANOVA), functional reach
(mean difference = 11.7%; 95% CI 7.1-16.3%, p < 0.003 MANOVA) and step test
(mean difference = 8.6%; 95% CI 3.8-13.4%, p < 0.003 MANOVA). Neither group had
improvements in SF36 quality of life measures. Results suggest progressive
resistance training produces greater strength, gait and balance improvements in
elderly people than a flexibility exercise program.
