Clinical Trial Summary

Research has demonstrated the positive effects of chronic exercise on cognitive functioning and performance of Activities of Daily Living (ADLs). However, minimal research exists regarding the effects of acute exercise. To address this gap in the literature, the present study investigated the effect of an acute bout of exercise on executive functions, balance, and ADLs among healthy older adults. Based on the current literature, we expected participants in the exercise group to perform better on executive function tasks and ADLs compared to participants in the control group.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Executive functions	Stroop test. The Stroop test is a measure of executive functions, specifically the ability to inhibit a habitual response, selective attention, and shifting (Pachana et al., 2014). This test requires participants to identify the color name printed in the same ink color (e.g., BLUE printed in blue ink; congruent condition) or different ink color (e.g., BLUE printed in red ink; incongruent condition). Each stimulus word (i.e., red, green, and blue) was presented in equal proportions to minimize specific word facilitation. After nine practice trials, 72 stimuli (i.e., 2 blocks of 36) were presented to the participants using the Eprime software (Version 3.0). Participants were asked to press the key with the dot sticker corresponding to the three stimuli colors (i.e., red, blue, or green). Reaction time (RT) and accuracy were used as indices of performance.	1 week
Primary	Balance	Berg Balance Scale (BBS). The BBS was developed to measure balance and fall risk among older adults. This scale is comprised of 14 tasks to assess balance, such as standing with eyes closed and retrieving an object from the floor. Performance is rated on a 0 to 4 scale for each task, with "0" indicating the lowest level of function and "4" the highest level of function. Total scores of 41 to 56 indicate a low fall risk, 21 to 40 a medium fall risk, and 0 to 20 a high fall risk (Berg et al., 1992).	1 week
Primary	Activity of daily living	Medication task. A medication task was developed to test the participants' ability to properly complete their pill organizers. Participants read a fictional story about prescribed medications and were asked to determine the required frequency and dosage of the medications based on the prescription and the label on fake medication bottles filled with candy pills. Participants had to place the medications in a weekly pill organizer for each required day and time slot (AM and PM). Two scenarios were designed to both require a similar number of pills to be placed in the weekly container for pre and post-test. Time to complete the task and number of mistakes for each day and time slot were recorded as indices of performance. Mistakes were recorded when participants added too many or too little pills, when pills were placed in the incorrect AM/PM time slot, or when participants added the wrong type of medication on a given day.	1 week
Primary	Functional ability	15 feet task. The 15-feet task measures functional ability in older adults. Participants are instructed to walk for 15 feet at their own pace while their performance is timed.	1 week
Primary	Fall risk	Time up and go (TUG). The TUG is used to measure fall risk in the elderly population and consists of instructing the participant to stand up from a chair, walk three meters, turn around, walk back, and sit down in the chair. The participants were instructed to walk at their regular pace and performance was measured as the time required to complete the activity. A timed score of greater than 14 seconds indicated a high risk of falls (Bohannon, 2006).	1 week
Primary	Grip strength	Grip strength. Verbecq et al. (2017) reported that low muscle strength, as measured by hand grip strength, was associated with a history of falls in older adults To measure hand grip strength, participants were asked to squeeze the handle of a handgrip dynamometer as hard as possible with their dominant hand and the mean score of three trials was recorded.	1 week
Primary	Commitment check	A commitment check was developed to test participants' commitment to the tasks. Participated were asked how committed they were while performing (a) the Stroop task, (b) the medication task, (c) the BBS tasks, (d) the TUG task, and (e) the grip strength task. Each item was rated on a scale ranging from 1 (none / not at all) to 10 (very much / very well).	1 week
