Time-course of health-related adaptations in response to combined training in hypertensive elderly: immune and autonomic modulation interactions

Abstract

Abstract Aims: This article is a methodological description of a randomized clinical trial (ClinicalTrials.gov U1111-1181-4455) aiming to evaluate the time-course (monthly) and associations between blood pressure changes and other health-related adaptations in response to exercise training in hypertensive elderly. Methods: The patients will be randomized to a control or combined training group interventions (aerobic and resistance exercise), with monthly assessments in four months. Although, the changes in baseline blood pressure is the primary clinical outcome, the secondary outcomes include: body composition, cardiorespiratory fitness, muscle strength, arterial stiffness, baroreceptor sensitivity, cardiovascular autonomic modulation, inflammatory markers, oxidative stress, growth factors, tissue remodeling markers, metabolic profile, renal function, cognitive function and quality of life. Results: To support the understanding of the blood pressure changes in hypertensive elderly, a time-course of exercise-induced adaptations including cardiovascular and immunological adaptations are fundamental for research in this field. Conclusion: To investigate the time-course of combined training-induced adaptations including all the diverse aspects of health in hypertensive elderly a well-controlled protocol design is necessary, mainly to clarify the relationship between cardiovascular and immunological exercise-induced adaptations.
