Summary

The following three-part proposal will focus on the effects of agility training as well as the relationship between agility ability and motor and cognitive function, and risk of falls in elderly adults with or without mild cognitive impairment (MCI). Part I is a cross-sectional study design that will assess the level of agility in healthy young adults, healthy elderly adults, and elderly adults with MCI to determine the effect of aging and cognition decline on agility and the relations between agility, cognitive, and motor functions. Thirty participants will be screened for eligibility and recruited for each group (90 participants total). After collecting basic data, all participants will undergo cognitive and motor function tests, as well as an agility test. Cognitive function tests include tests of global cognition, working memory, mental set shifting, and selective attention. Motor function tests include tests of single and dual task walking, strength, power, balance, flexibility, and endurance. The agility test contains stop-and-go, change of direction, and spatial orientation components. Functional near-infrared spectroscopy (fNIRS) will be used to evaluate the brain activation during the agility test, cognitive tests, and single and dual task walking. Results from all tests will be used to determine the motor, cognitive, and other predictive factors associated with agility performance, and will be used in the design of the training program in Part II and III. Part II and III are single-blinded randomized controlled trials that will explore the short and long-term effects of a multicomponent training and an agility training protocol on agility, motor, and cognitive function in elderly adults with and without MCI. Seventy-five elderly adults with MCI (Part II) and seventy-five healthy elderly (Part III) will be recruited. After screening for eligibility and collection of demographic data, participants will undergo a pretest assessment. In addition to the motor, cognitive, and agility tests used in Part I, information on history of falls, falls efficacy, and quality of life will be assessed for each participant. Brain activation will be assessed during the agility test, cognitive tests, and single and dual task walking assessments using fNIRS. Participants will be randomly allocated into one of three groups: the control group, the multicomponent training group, or the agility training group (n=25 in each group). Intervention will be executed at a frequency of 45 minutes per session, 2 times a week for 8 weeks. The control group will receive home-based health education guidelines. The multicomponent training group will engage in 3 to 4 exercises each training session comprising the influencing factors of agility, and the agility training group will engage in integrated task-specific training. A post-test will be conducted after the 8-week intervention, and 1-month, 6-month, and 12-month follow-ups will be conducted for elderly adults with MCI. The healthy elderly adults will be assessed after the intervention and at the 1-month follow-up after training.

• Healthy

Interventions

Type	Name	Description
OTHER	Health education	Participants in the control group will receive health educational guidelines. Guideline contents include home-based exercise program, nutrition recommendations, and fall prevention education.
OTHER	Multicomponent training	Multicomponent exercises will be designed according to the results of Part I of our study. Results of Part I of this study will determine the contributing factors of agility, such as muscle strength, endurance, and cognitive function. A physical therapist will train the participants 3-4 exercises (3-4 factors) in each session. The physical therapist will adjust the difficulty of each exercise according to the participant's ability and condition.
OTHER	Agility training	The agility-based task-specific exercises will be conducted in this group and will incorporate stop-and-go, change in direction, change in velocity, acceleration and deceleration training. There are four training configurations with 3 levels of difficulty, which will be manipulated by increasing speed, distance, number of repetitions, number of directions, congruency, and/or complexity of the task, or by decreasing the number and duration of the rest intervals. The physical therapist will adjust the difficulty of each exercise according to the participant's ability and condition.
