Summary

The Heart-Brain project is a randomized controlled trial designed to examine the effects of two different exercise programs of 12-week duration: 1) aerobic high intensity interval training (HIIT), and 2) aerobic HIIT plus resistance training, on brain health and other outcomes in coronary heart disease patients.

Detailed description

Patients with coronary heart disease (CHD) has higher risk of developing dementia, cognitive impairment, and mental disorders. There is, therefore, a need to identify effective and sustainable initiatives to avoid or attenuate cognitive and mental health declines in these patients, and in this context, physical exercise can play a major role. The overall objective of the present project is to investigate the effects of exercise on brain health outcomes in CHD patients. The Heart-Brain project is a single-blinded, exercise-based randomized controlled trial. We will run a three-arms trial with a waiting-list control group, and two intervention groups that will receive two different supervised exercise programs: 1) aerobic high intensity interval training (HIIT) and 2) a combination of aerobic HIIT plus resistance training. The study will be conducted in 90 patients with CHD who meet the eligibility criteria indicated below.

Conditions

• Coronary Heart Disease

Interventions

Type	Name	Description
BEHAVIORAL	Two types of exercise interventions	* HIIT. 3 times/week. This consists of a 4x4 HIIT (preferably in treadmill), 4 intervals of 4min at high intensity (85-95% HRmax) and 3 intervals of 3min of active resting at \~70% HRmax in between. All sessions including 10 min of warming-up and 10min of cooling down, resulting in 45min sessions. The first 2 weeks will progress from moderate-intensity training to HIIT for a better adaptation and acceptability of the program. * HIIT + resistance. 3 times/week. The aerobic part consists of a 3x4 HIIT (preferably in treadmill), 3 intervals of 4min at high intensity (85-95% HRmax) and 2 intervals of 3min of active resting (\~70% HRmax) in between. The resistance part consists of 2 series of an 8-exercise circuit (combination of upper and lower body exercises using elastic bands and body weight) with a ratio of 20sec of effort - 40sec of resting. Sessions will have 5min of warming up in the treadmill and 5min of cooling down walking in the gym, comprising a total of 45min sessions.
