Title: SYNchronizing Exercises, Remedies in GaIt and Cognition (SYNERGIC): A Randomized Controlled Double Blind Trial
Brief Summary: The proposed SYNERGIC trial is uniquely designed to evaluate the effect of aerobic and progressive resistance training exercises, combined with cognitive training and Vitamin D3 supplementation, in cognition and mobility in older adults with Mild Cognitive Impairment (MCI).


Options:
A: Inclusion Criteria:

* Patients who meet the Peterson diagnostic criteria of MCI:

  1. memory complaints (preferably confirmed by an informant).
  2. memory impairment according to age and education.
  3. preserved general cognitive function.
  4. intact activities of daily living, absence of dementia.

Exclusion Criteria:

* head trauma with post-traumatic loss of conscience for 30 minutes during lifespan.
* loss of senses (blindness, deafness).
* photo-sensitive epilepsy.
* unsuitability for Magnetic Resonance Imaging-examination due to metal foreign bodies or severe claustrophobia.
* drug and/or alcohol abuse.
B: Inclusion Criteria:

1. At least 60 years of age
2. Self-reported levels of proficiency in English (French for Montreal site only) for speaking and understanding spoken language.
3. Able to comply with scheduled visits, treatment plan, and other trial procedures
4. Able to ambulate at least 10 meters independently
5. Having MCI operationalized using Albert et al. criteria as:

   * objective cognitive impairment in one of the following four cognitive domains: memory, executive function, attention, and language evaluated by the Montreal Cognitive Assessment (MoCA) test with scores ranging from 13-24/30.
   * Preserved activities of daily living on the disability scale confirmed by clinician interview
6. Having normal or corrected to normal vision in at least one eye so that they can identify symbols and stimuli presented on a computer screen in front of them.
7. Must be in sufficient health to participate in the study's aerobic-based exercise training program, based on medical history, vital signs, physical examination by study physicians, or written recommendation by family physician indicating one's appropriateness to participate in aerobic-based exercise training program.

Exclusion Criteria:

1. Serious underlying disease (such as active cancer, or recent heart attack) which, in the opinion of the investigator, may preclude engagement in interventions or may interfere with the participant's ability to participate fully in the study.
2. Diagnosis of dementia using criteria from the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition.
3. Participant with uncontrolled major depression, schizophrenia, severe anxiety and substance abuse.
4. Current parkinsonism or any neurological disorder with residual motor deficits (e.g. stroke with motor deficit), active musculo-skeletal disorders (e.g. severe osteoarthritis of lower limbs) or history of knee/hip replacement affecting gait performance at clinical evaluation.
5. Intention to enroll in other clinical trials during the same time period
6. Pre-existing exercise structured training program involving aerobic or resistance training in previous 6 months.
7. Taking cognitive enhancers, neuroleptics, anticholinergics or Vitamin D3 in doses more than 1000IU/day or equivalent.
C: Inclusion Criteria:

1. able to follow instruction,
2. clinical dementia rating (CDR) = 0.5 or 1,
3. self- or informant-reported memory or cognitive complaint, and
4. able to perform activities of daily living (Barthel Index ≥ 70).

Exclusion Criteria:

1. recent myocardial infarction,
2. heart failure,
3. recent heart surgery,
4. severe asthma,
5. concomitant with other neurological disorders, or
6. joint deformity that might prevents them performing exercise or cognitive training.
D: Inclusion Criteria:

* no severe cognitive impairment \[MMSE ≥ 18\]
* fluent language skills
* agreement of a medical doctor
* time commitment to the test and exercise protocol.

Exclusion Criteria:

* concurrent participation in another study
* severe physical or psychological disorders which precluded participation in the intervention (i.e., inability to follow instructions)
* unrecovered neurological disorders such as stroke, traumatic brain injury, unstable medication within the past three months
* severe and uncorrectable vision problems, or hearing aid for less than three months.
