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.

Interventions

OTHERHigh-intensity interval Hydrogynmastics

The HIIH to PSE group during the high intensity (HI) period should remain between 16 to 18 points, while in the moderate intensity (MI) intervals around 11. The dynamic exercises will progression, in the first month will be 1 min of HI and 2 min of MI, in the second month of 1 min of HI and 1 min of MI and in the last month of 1 min of HI and 30 s of MI, until completing 30 min in total.

OTHERHydrogynmastics Continuous Moderate

For the HCM group the PSE will be around 11 points during the 30 min of moderate continuous exercise. In both groups the form of intensity monitoring that will be through the PSE, in which this scale will be printed in banner form and affixed next to the physical education teacher during the classes.

Design outcomes

Primary

MeasureTime frameDescription
Aerobic Fitnessthree months after randomizationThis maximal/submaximal test will be performed on cyclergometer, Balke test.
Body Compositionthree months after randomizationThe body composition (density and percentage of body fat) will be estimated by prediction equations (JACKSON et al., 1980).
Strength Muscularthree months after randomizationStrength Muscular will be measured by 1RM test in two exercises, involving the segments of the upper limbs (supine) and lower limbs (leg press).
Endurance Muscularthree months after randomizationMuscle 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.

Secondary

MeasureTime frameDescription
Perception of Improvementthree months after randomizationPerception of Improvement will be measured by an Likert-type Improvement Scale
Quality Lifethree months after randomizationQuality of life by assessed by WHOQOL-breaf
