HIIH Versus HMC: Randomized Clinical Trial

Effectiveness of High-intensity Interval Versus Intensity Continuous Hydrogymnastics for Improvement of Health Outcomes: Randomized Clinical Trial.

Introduction: water aerobics involves the practice of specific aquatic exercises that are based on the use of water resistance as a load and on thrust as an impact reducer, making it possible to perform physical exercise with a lower risk of injury even at a high intensity. Objective: The overall objective of this study will be to compare the effectiveness of high intensity interval versus moderate continuous water aerobics to improve health outcomes in apparently healthy individuals.

Method: randomized clinical trial will be performed in the premises of the College of Physical Education of the Federal University of the São Francisco Valley. 100 adults, of both sexes, will be randomized into two groups, high intensity interval hydrogynastic (HIAI) or moderate continuous aquatic gymnastics (HCM). Individuals will be evaluated for primary endpoints of muscle strength and endurance, aerobic fitness, flexibility and body composition. The secondary outcomes evaluated will be the quality of life, functionality and perception of improvement by a Likert-type Improvement Scale, at the following moments: initial, final and follow-up of one month after the end of the training. Individuals will be assisted for three months, often weekly twice, with sessions lasting 50 min. In order to identify differences between and within the groups, an equation of generalized estimates will be used as regression model with the syntax according to the multivariate model.

Inclusion Criteria:

• age between 18 and 60 years;
• sedentary and who did not perform physiotherapy and physical activity in the last three months;
• clinical and cognitive conditions for swimming pool activities and aerobic exercise; who have not undergone highly complex surgical procedures in the last six months;
• to be able of walking without help equipment and without musculoskeletal or skeletal diseases;
• without contraindications to the practice of exercises; such as: urinary and / or fecal incontinence and dermatological diseases;
• below obesity II with BMI <40.

Exclusion Criteria:

• if they have up to three consecutive fouls during the hydrogymnastics period;
• if they present any adverse effects, such as: allergy or any dermatitis;
• unable to continue the study due to change of address or hospitalization.
