About this study
Official title: Effects of Two Water-based Aerobic Training Programs on Cardiorespiratory and Neuromuscular Parameters in Elderly Women: a Randomized Controlled Trial
The aim of the study is to investigate the effects of two water based aerobic training programs on cardiorespiratory, neuromuscular and quality of life parameters in old women.
Volunteer old women age range: 60-75 years old, will participate to this study, and will randomly divided into two groups: continuous aerobic training group and interval aerobic training group.

Both group subjects will participate in two-week training sessions during 12 weeks. Independent of the group, participants will perform three water-based exercises: stationary running, frontal kick and cross-country skiing. The intensity of aerobic exercise will be based Rating Perceived Exertion (RPE). Along the training, the intensity of aerobic exercise will increase in both groups. Before and after intervention, there will be evaluation of muscle quality, muscle thickness, peak oxygen uptake and oxygen uptake at ventilatory threshold, maximal isometric and dynamic strength of knee extensors, maximal and submaximal isometric eletromiografy (EMG) activity of vastus lateralis and rectus femoris, muscle endurance, performance in functional tests and assessment of the perception of quality of life.
Data will be analyzed by Generalized Estimating Equations (GEE) and Bonferroni's post-hoc test (α=0.05), including both protocol and intention to treat analyses (α=0,05).
Read the detailed description
Aging is associated with impairment in cardiorespiratory fitness, strength performance and muscle mass decrease, which affects the functional capacity of older adults directly. Consequently carrying out routine activities can be harmed. However regular exercise practice points out as an efficient tool to mitigate factors associated with aging.
Therefore, carrying out water-based exercises has been widely suggested for older adults due to their advantages, such as low impact on lower limbs and lower cardiovascular load.
The aim of the study is to investigate the effects of two water based aerobic training programs on cardiorespiratory, neuromuscular and quality of life parameters in old women.
Volunteer old women age range: 60-75 years old, will participate to this study, and will randomly divided into two groups: continuous aerobic training group and interval aerobic training group.
Both group subjects will participate in two-week training sessions during 12 weeks. Independent of the group, participants will perform three water-based exercises: stationary running, frontal kick and cross-country skiing. The intensity of aerobic exerecise will be based Rating Perceived Exertion (RPE). Along the training, the intensity of aerobic exercise will increase.
Participants who will be randomized for the continuous aerobic training group will carry out exercises with no interval for exercise change. Intensity will be increased every mesocycle. In the first mesocycle (weeks 1-4), participants will carry out three 4-minute series of each exercise whose intensity corresponds to the Rating of Perceived Exertion (RPE) 13. In the second mesocycle (weeks 5-8), participants will perform four 3-minute series of each exercise corresponding to RPE 14. In the third mesocycle, participants will perform six 2-minute series of each exercise at intensity corresponding to RPE 15 from weeks 9-10, whereas intensity corresponding to RPE 16 will be experienced from weeks 11-12.
Participants who will be randomized for interval aerobic training group will carry out exercises which associate effort phases, at higher intensity and recovery phases, at lower intensity, with no interval for exercise change. Intensity will be increased every mesocycle. The first mesocycle (weeks 1-4) comprises three 4-minute series of each exercise whose intensity corresponds to the RPE 16 for 2 minutes and RPE 11 for 2 minutes. The second mesocycle (weeks 5-8) includes four 3-minute series of each exercise whose intensity corresponds to the RPE 17 for 1.5 minutes and RPE 11 for 2 minutes. The third mesocycle (weeks 9-12) comprises six 2-minute series of each exercise whose intensity corresponds to the RPE 18 for 1 minute and RPE 11 for 1 minute.
Before and after intervention, there will be evaluation of muscle quality, muscle thickness, peak oxygen uptake and oxygen uptake at ventilatory threshold, maximal isometric and dynamic strength of knee extensors, maximal and submaximal isometric eletromiografy (EMG) activity of vastus lateralis and rectus femoris, muscle endurance, performance in functional tests and assessment of the perception of quality of life.
Data will be analyzed by Generalized Estimating Equations (GEE) and Bonferroni's post-hoc test (α=0.05), including both protocol and intention to treat analyses (α=0,05).

What is being measured
The primary outcome is the main question the study is designed to answer.
Cardiorespiratory Fitness evaluation change after 12 weeks
We created a protocol on the treadmill to determine the peak oxygen uptake change(VO2peak), the first ventilatory threshold and the second ventilatory threshold. The protocol consists in 1-minute stages. The initial speed is 1.86 miles per hour. In each stage, the speed increases 0.3 miles per hour and every 2 stages, the treadmill inclination increases 1%. The test is interrupted when the subject indicates exhaustion. The respiratory gases will be collected through a portable gas analyzer (VO2000, MedGraphics, Ann Arbor, USA).
The maximum value of VO2 , closed to exhaustion will be considered the VO2peak. The fist and the second ventilatory threshold will be determined by the ventilation versus intensity curve and confirmed by the O2 and Carbon dioxide ventilatory equivalents by two independent physiologists in a visual inspection.

Questions about this trial
What is this clinical trial studying?
A study testing water-based continuous aerobic training and water-based interval aerobic training in people with Elderly Women, run by Federal University of Pelotas at 1 site in Brazil.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 15 Jan 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Cardiorespiratory Fitness evaluation change after 12 weeks (time frame: Testing of VO2peak change - Baseline and 12 week). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Jan 2019.
