Scientific title	MoCog - Intervention study on motor and cognitive performance of older adults with and without Alzheimers disease [MoKog - Eine Interventionsstudie zur körperlichen und geistigen Leistungsfähigkeit bei älteren Personen mit und ohne Alzheimer Demenz]
Study acronym	MoCog [MoKog]
Study objectives	The aims of the study are: 1. To analyse the differences in motor and cognitive performance between: 1.1. Healthy and demented persons 1.2. Physically active and inactive persons 2. To show whether increased physical activity reduces the progression of Alzheimer's disease 3. To examine the relationship between physical activity across life span and cognitive performance 4. To examine: 4.1. The correlation of motor and cognitive performance 4.2. The influence of Alzheimer's disease on motor performance 4.3. The effect of the genetic risk factor APOE4 on cognitive performance and health-related fitness 5. To improve motor and cognitive performance through exercise training 6. To compare the effectiveness of different exercise programs (endurance and strength training) 7. To evaluate the feasibility and acceptance of the exercise training program
Ethics approval(s)	Ethics-Committee of the Institute of Pharmacology and Toxicology, Rheinische Friedrich-Wilhelm University of Bonn, gave approval on the 21st November 2003 (ref: 156/03). Amendment on 23rd January 2006 (ref: 179/03).
Health condition(s) or problem(s) studied	Alzheimer's disease
Intervention	1. Intervention group: Participants exercise two times per week for three months. Every session comprises 60 minutes (5 - 10 minute warm-up and 5 - 10 minute cool-down on an ergometer). Participants were divided into either a strength training group or an endurance training group: 1.1. Strength training group: Weight training of the major muscle groups for 60 minutes per session. Starting with strength-endurance and intramuscular coordination training (40 - 60% of one repetition maximum [RM], three sets of 20 repetitions) in the initial starting program (first 4 weeks), followed by hypertrophy training (80% of one RM, three sets of 8 - 12 repetitions) for 8 weeks. The intensity of loading was gradually increased, adapted on subjectively perceived exertion (16 to 18 points on the Borg scale). 1.2. Endurance training group: The endurance training on an ergometer was in accordance with the American College of Sports Medicine's (ACSM's) guidelines for exercise prescription. Volume and intensity of effort were gradually increased every week, starting at 20 minutes and 50 - 60% heart rate (HR) and ending at 60 minutes and 75 - 80% HR max. 2. Control group: The participants of the control group received no intervention. Possible changes in physical activities in the intervention group and control group were controlled by a questionnaire. Total duration of treatment: 24 training sessions Total duration of follow-up: 2 - 5 days Scientific Contact details: Dr Sabine Eichberg Institute of Sport Gerontology German Sport University Cologne Am Sportpark Muengersdorf 6 Cologne 50933 Germany Email: eichberg@dshs-koeln.de

Flexibility (trunk and head rotation, back scratch, sit and reach) 2.5. Reaction and movement time (simple/choice reaction) 2.6. Fine motor movement (hand-eye coordination) 2.7. Balance (Romberg Test with and without visual control, Tandem and Semi-Tandem Stand) 3. Cognitive function, measured pre-test and post-test: 3.1. Cognitive screening (Mini Mental Status Test [MMST]) 3.2. Vocabulary (Multiple-Choice Word Test [MWT-B]) 3.3. Immediate verbal and visual-spatial memory span (Corsi Block Tapping Test) 3.4. Digits forward/backward (Wechsler Adult Intelligence Scale [WAIS]) 3.5. Information processing speed and attention (d2, Trail-Making Test Parts A and B [TMT A/B]) 3.6. Perceptual speed and response inhibition (cerebraler Insutfizienz Test [c.I.Test]) 3.7. Word fluency and mental rotation (Leistungsprufsystem [LPS]) 3.8. Anticipation and planning (Maze Test) 3.9. Verbal learning (Verbaler Lern- und Merkfähigkeitstest [VLMT])
Key secondary outcome measure(s)	1. Health status, measured pre-test and post-test: 1.1. Body composition 1.2. Chronic diseases 1.3. Functional limitations 1.4. Pain 1.5. Rate of falls 1.6. Medication 1.7. Geriatric assessment 1.8. Self-related health (5-point-Likert scale) 1.9. Depression rating scale 1.10. Locus of control 2. Activities, measured pre-test and post-test: 2.1. Leisure time and social activities 2.2. Physical activities (manner, duration, frequency, intensity, last 12 months and across life span) 3. Feedback (from Alzheimer patients and caregiver/family member) on exercise program, measured post-test only
