• Conditions: Healthy People
• Interventions: Other: Hydrogynmastics Continuous Moderate; Other: High-intensity interval Hydrogynmastics

• Registration Number: NCT03293056
• Lead Sponsor: Universidade Federal do vale do São Francisco

Brief Summary

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.

Detailed Description

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.

Arm && Interventions

Group	Intervention	Description
Hydrogynmastics Continuous Moderate	Hydrogynmastics Continuous Moderate	Hydrogynmastics Continuous Moderate training (HCM), 2x/week, for 3 months.

Primary Outcome Measures

Name	Time	Method
Aerobic Fitness	three months after randomization	This maximal/submaximal test will be performed on cyclergometer, Balke test.
Body Composition	three months after randomization	The body composition (density and percentage of body fat) will be estimated by prediction equations (JACKSON et al., 1980).
Endurance Muscular	three months after randomization	Muscle endurance will be assessed by the test in which the individual performs the maximum number of repetitions of given exercises for one minute. The exercises will be of arm and abdominal flexion.
Strength Muscular	three months after randomization	Strength Muscular will be measured by 1RM test in two exercises, involving the segments of the upper limbs (supine) and lower limbs (leg press).

Secondary Outcome Measures

Name	Time	Method
Quality Life	three months after randomization	Quality of life by assessed by WHOQOL-breaf
Functionality	three months after randomization	Functionality will be assessed by IVCF-20
Perception of Improvement	three months after randomization	Perception of Improvement will be measured by an Likert-type Improvement Scale
