The purpose of this study is to compare the effects of different trainings on cognition and physical performances in elderly over 80 years.
Purpose: To compare the effects of 16-week multicomponent and resistance trainings on cognition and physical performances related to falls in oldest old people living in community; to analyze the same variables after 6-week detraining. Method: We conducted a randomized controlled trial with 69 community elderly over 80 years, sedentary and without cognitive disorder. Participants were allocated to control, multicomponent training or resistance training group. The multicomponent group performed a protocol involving warm-up, aerobic, strength, balance and cool-down exercises. The resistance group underwent to strength exercises using six machines: leg press, chest press, calf, back extension, abdominal and rowing. The control group did not perform any intervention. The trainings had progressive intensity, lasted 16 weeks and included three 1-hour sessions per week. The participants were evaluated at baseline, at the end of 16-week training and at 6-week detraining. The assessment consisted of anamnesis, depression (Geriatric Depression Scale), cognition (Montreal cognitive assessment), dual task walking (associated to cognitive and motor tasks), balance (unipedal and tandem tests), strength of lower limbs (sit-to-stand test) and history of falls. For statistical analysis by intention to treat, we adopted a significance level of α=0.05.

The multicomponent training consisted of individuals subjected to a multicomponent exercise program: 5 minute warm up, 20 minutes of aerobic exercise, 15-20 minutes of strength exercises, 10 minutes of coordination, agility and balance exercises and 5 minute of cool-down.
The resistance training was subjected to a strength training using weight machines adapted for elderly. The protocol followed three sets of 10 to 12 maximal repetitions, moderate speed (two seconds for the shortening phase and three seconds for the elongation phase) and one minute for rest interval between sets.

Changes from baseline in lower limbs strength after 16 weeks of training and 6 weeks of detraining
Lower limbs strength was assessed by 5 times sit-to-stand test.
Time frame: Assessed at baseline, after 16 weeks of training and 6 weeks of detraining
Changes from baseline in balance after 16 weeks of training and 6 weeks of detraining
Balance was assessed by unipedal test and tandem test.
Time frame: Assessed at baseline, after 16 weeks of training and 6 weeks of detraining
Changes from baseline in dual task walking after 16 weeks of training and 6 weeks of detraining
Dual task was assessed by Timed Up and Go test with a cognitive task (speak day of week in reverse order) and motor task (carry a cup of water).
Time frame: Assessed at baseline, after 16 weeks of training and 6 weeks of detraining
Changes from baseline in cognition after 16 weeks of training and 6 weeks of detraining
Cognition was evaluated by Montreal Cognitive Assessment.
Time frame: Assessed at baseline, after 16 weeks of training and 6 weeks of detraining.
Changes from baseline in number of falls after 16 weeks of training and 6 weeks of detraining
Presence of falls was assessed by falls calendar and phone calls.
Time frame: Assessed at baseline, during 16 weeks of training and 6 weeks of detraining.
Changes from baseline in depression after 16 weeks of training and 6 weeks of detraining
Depression was assessed by abbreviated Geriatric Depression Scale.
Time frame: Assessed at baseline, during 16 weeks of training and 6 weeks of detraining.
