NCT01906957

Brief Summary

The aim of study is to investigate the impact of two different training modalities (high intensity interval training (HIIT) versus moderate intensity continuous exercise training (MICET) on cognitive performance, cerebral oxygenation, cardiac output and physical fitness in older healthy adults, patients with metabolic syndrome, coronary heart disease and heart failure. The investigators hypothesized that HIIT modality will lead to a larger improvement in physical fitness (i.e. VO2peak), cardiovascular parameters (cardiac output and stroke volume) and cognitive performance at rest and during submaximal exercise. The primary endpoint will be the improvement in cognitive performance.

Interventions

High-intensity interval exercise (HIIE) session This HIIE session will be based on a previous study conducted in our laboratory that compared physiological, psychological and electrocardiological tolerance of four different single bouts of HIIE in coronary patients (Guiraud et al. 2010). The selected HIIE session represented the best compromise between safety, time spent at a high level of VO2peak and psychological adherence. This HIIE session consists of a 10-min warm-up at 50% of MAP, followed by two sets of 10 min composed of repeated bouts of 15 s at 100% of MAP interspersed by 15 s of passive recovery. Four minutes of passive recovery were allowed between the two sets, as well as a 5-min cool-down after the last 15-s exercise bout. A total duration of 35 minutes will be employed for this session for coronary artery disease patients, and 22 minutes for chronic heart failure patients (Guiraut et al. 2010 b).

Moderate Intensity Continuous Exercise (MICE) session This exercise session will be based on the recommendations of the American Heart Association on exercise prescription in cardiac rehabilitation (Balady et al. 2007), suggesting that exercise intensity should lie between 50% and 80% of maximal aerobic power (MAP). We opted for an intensity of 70% of MAP. Duration will be adjusted to match total energy expenditure of the HIIE, according to the previous methodology method (Guiraud et al. 2010 b). A total duration of 28.7 minutes will be employed in healthy elderly patients, coronary artery disease patients and patients with metabolic syndrom; and 16 minutes in chronic heart failure patients.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Elderly healthy subjects : with no MetS and no-documented CHD, both males and females, aged\>60 years will be included in the study, should they provide written informed consent and have a sufficient initial physical and intellectual capacities allowing an independent daily living.
  • Patients with metabolic syndrome and no-documented CHD, both males and females, aged \> 18 years will be included in the study, should they provide written informed consent and have a sufficient initial physical and intellectual capacities allowing an independent daily living. MetS will be defined according to recent updated criteria: presence of at least three of five criteria, namely abdominal obesity (waist circumference cut-off depending on the recently published ethnic-based variations, triglycerides \> 1.70 mmol/l, decreased HDL-cholesterol (\< 1.0 mmol/l in men and \< 1.3 mmol/l in women), systolic blood pressure \> 130 mmHg or diastolic blood pressure \> 85 mmHg, and FPG \> 5.6 mmol/l.
  • CHD patients, both males and females, aged \> 18 years will be included in the study, should they provide written informed consent and have a sufficient initial physical and intellectual capacities allowing an independent daily living. Moreover, they must have documented CHD (prior myocardial infarction, prior coronary angiography or angioplasty, or documented myocardial ischemia on myocardial scintigraphy).
  • ≥18 years
  • Left ventricular ejection fraction (LVEF) \<40% (measured within 6 months of their enrolment by MUGA Scan, echo or radiological ventriculography)

  • coronary heart disease
  • chronic systolic heart failure
  • resting left ventricular ejection fraction \< 40 %
  • symptomatic aortic stenosis
