Brief Summary

The goal of this clinical trial is to test a newer type of high intensity interval resistance training in adults 65 years of age or older. The main aims of this study are:

  1. 1.To develop study procedures in order to conduct a randomized controlled trial to test the impact of high intensity interval training on cognition in older adults. We will develop procedures for recruitment, screening, data collection, blinded randomization, HIIRT and EA interventions, safety monitoring, and data analyses.
  2. 2.To determine the feasibility of using high intensity interval resistance training as an intervention. Feasibility will be shown by; 1) recruiting the target population and meeting our overall patient accrual goal of 30 participants over a 12-week period, 2) achieving an average attendance rate of ≥ 70% of the 24 scheduled sessions in the HIIRT group, 3) at least 80% retention of participants at the final follow-up assessment (week 12), and 4) successful completion of the MRI task (finishing the session with a behavioral accuracy greater than 70%) by at least 80% of participants. Acceptability will be assessed via participants' ratings on a standardized measure of treatment satisfaction and reasons for dropout. Acceptability will be indicated in 2 ways: 70% of the participants report treatment satisfaction on a standard questionnaire, and consistent collection of follow-up data across sites.
  3. 3.To examine causal mechanisms and preliminary efficacy. We will examine the relationships among several proposed mediators of the expected treatment effect. We will also examine the mean change and variability of our primary outcomes.

Outcome Measures

Primary Outcomes (3)

  • Executive Functioning

    Executive Functioning will be operationalized as an index of several computer-based tasks assessing aspects of executive functioning: Inhibition (Stroop Test), Updating (The 4-part continuous performance task), and Switching (Shifting attention task, Symbol Digit Coding).

    Baseline and 12-weeks

  • Gradual Continuous Performance Test

    Participants will make continuous responses to target picture stimuli (images of cities among distractor images of mountains). Periodically, a colored border will appear around each location, cuing the participant to attend to either the left or right picture stream. If the currently cued stream differs from their previous focus of attention, the participant will make a saccadic eye movement. At the same time as the color onset, a number will appear at each location. Participants will then make an even/odd discrimination for stimuli appearing at the to-be-attended location.

    Baseline and 12-weeks

  • Functional Magnetic Resonance Imagining

    Participants will complete a 60-minute magnetic resonance imagining session during which will acquire a high-resolution anatomical scan, an echo planar image while participants complete the Gradual Continuous Performance Test. This task is a cognitive task designed to measure the neural correlates of moment-by-moment fluctuations in the efficacy of sustained attention and attention shifting readiness, termed attentional flexibility, a resting state scan, and a diffusion tensor imaging to measure white matter tract integrity.

    Baseline and 12-weeks

Secondary Outcomes (11)

  • Brain Derived Neurotrophic Factor

    Baseline and 12-weeks

  • The Physical Activity Enjoyment Scale

    Baseline and 12-weeks

  • Community Health Activities Model Program for Seniors Activity Questionnaire for Older Adults

    Baseline and 12-weeks

  • Basic Psychological Need Satisfaction and Frustration Scales

    Baseline and 12-weeks

  • SF-36 Health Questionnaire

    Baseline and 12-weeks

  • +6 more secondary outcomes

Study Arms (2)

Stretching, Balance, Range of Motion

ACTIVE COMPARATOR

Participants will engage stretching, balance, and range of motion exercises 2 days per week for 12-weeks.

Behavioral: Stretching, Balance, and Range of motion

High Intensity Interval Resistance Training

EXPERIMENTAL

Participants will perform resistance training exercises at high intensity intervals 2 days per week for 12-weeks.

Behavioral: High Intensity Interval Resistance Training

Interventions

During each group exercise session, the participants will be guided through a 5-minute warm-up, supervised to perform two sets of machine-based leg press, chest press, seated row, and shoulder press exercises at 30% of 1-RM, and guided through a cool-down. Each exercise set will be 40 -seconds in length with instructions to perform as many repetitions as possible followed by a 20-second rest in between sets and a three-minute rest between exercises.

High Intensity Interval Resistance Training

The stretching, balance, and range of motion intervention will include a rotating and varied routine of stretching exercises for large and small muscle groups, and activities to improve balance and range of motion. Participants will attend this intervention twice a week with each session lasting 30 minutes.
