Comparison of High-Intensity Interval Training and Moderate-Intensity Continuous Training on Executive Functions, Cardiorespiratory and Physical Fitness in Older Adults With Mild Cognitive Impairment
In Brief
A clinical study evaluating High-Intensity Interval Training (HIIT) and Moderate-Intensity Continuous Training for Mild Cognitive Impairment. Completed, enrolled 68 participants across 2 sites.
Signals
Detailed Summary
This study aims to determine the effects of High-Intensity Interval Training (HIIT) and Moderate-Intensity Continuous Training (MICT) on cognitive and physical fitness in community-dwelling adults diagnosed with Mild Cognitive Impairment (MCI). A double-blinded randomized clinical trial will be conducted for ten months at Ruhama Welfare Foundation Society Lahore and Kainat Patient Care and Old Age Home, Lahore. The sample size is calculated through G-power and 68 participants will be recruited through the non-probability convenience sampling technique. Those who meet the inclusion criteria will be randomized into two groups through the online randomizer tool. Both experimental groups will undergo an 8-week intervention, consisting of three sessions per week with alternate-day training of 38 minutes. The HIIT group will perform exercise with each session consisting of four 4-minute intervals at 85-95% of their maximum heart rate, with 3-minute active recovery periods, while the MICT group will engage in continuous exercise for 28 minutes at 70-75% of their maximum heart rate. Assessment will be done at baseline, after the 4th week, 8th week, and follow-up at 12th week.

Arms & Interventions
The High-Intensity Interval Training Group (HIIT)
Moderate-Intensity Continuous Training (MICT)
Interventions
The HIIT group will engage in 28 min of alternating high-intensity and low-intensity exercise, where the high-intensity phase will be at 85-90% of maximum heart rate for 4 min, followed by a 3-min recovery period at 50-60% of maximum heart rate, repeated four times on a treadmill or stationary bicycle. (RPE \~16 on Borg scale) Total duration will be 38 minutes including warm up and cool down period.
The MICT group's training will consist of continuous aerobic exercise for 28 min at 60-70% of maximum heart rate on a treadmill or stationary bicycle. (RPE \~13 on Borg scale) Total duration will be 38 minutes including warm up and cool down period.
