They compared the cardiorespiratory responses to exercise on an underwater treadmill (UTM) and land treadmill (LTM) and derived an equation to estimate oxygen consumption (VO2) during UTM exercise
55 men and women completed on LTM and five UTM session on separate days .
The UTM session consisted of chest-deep immersion with 0,25,50,75, and 100% water-jet resistance . All session treadmill velocities increase every 3 min from 53.6 to 187.8 m.min-1
![Page 19: Aquatic exercise](https://reader036.vdocument.in/reader036/viewer/2022070512/589d82bc1a28ab69538b7057/html5/thumbnails/19.jpg)
Method
First part : designed to compare and contrast submaximal and maximal cardiorespiratory responses to UTM and LTM exercise
Second part : designed to develop and equation to estimate VO2 .
Recruited additional 11 participants to exercise in a second UTM system ( different model ) to strengthen their ability to accurately estimate vo2 across other UTM systems
![Page 20: Aquatic exercise](https://reader036.vdocument.in/reader036/viewer/2022070512/589d82bc1a28ab69538b7057/html5/thumbnails/20.jpg)

Participant were then fitted on a HR monitor and a mask connected to an automated metabolic gas analyzer .
The gas analyzer was calibrated after each exercise session
During the exercise session expired metabolic gases were measured continuously and HR and RPE were during last 30 s of each exercise stage
![Page 22: Aquatic exercise](https://reader036.vdocument.in/reader036/viewer/2022070512/589d82bc1a28ab69538b7057/html5/thumbnails/22.jpg)
Each participant completed six
experimental exercise session on different days
LTM at 0% grade
UTM at 25% jet resistance
UTM at 50% jet resistance
UTM at 75% jet resistance
UTM at 100% jet resistance
VO2 max for UTM exercise was taken the highest VO2 achieved at volatile exhaustion during UTM exercise session
treadmill velocities increase every 3 min from 53.6 to 187.8 m.min-1 for every season

Purpose
To evaluate the effectiveness and safety of water-based exercise for adults with asthma.
![Page 66: Aquatic exercise](https://reader036.vdocument.in/reader036/viewer/2022070512/589d82bc1a28ab69538b7057/html5/thumbnails/66.jpg)
Methods
They included randomized controlled trials (RCTs), regardless of language, age of publication or publication status.
A cross-over RCTs were also included; however they analyzed separately the data obtained from them.

They considered participants who met the following criteria: Adults of either gender. Adults with asthma diagnosed according to clinical criteria
Studies that compared any type of water-based exercise versus another type of water-based exercise, land-based exercise or usual care were included .
![Page 68: Aquatic exercise](https://reader036.vdocument.in/reader036/viewer/2022070512/589d82bc1a28ab69538b7057/html5/thumbnails/68.jpg)
They documented the duration and frequency of sessions and the overall length of the programme.
At least one group in each comparison used water-based exercise.
The following possible comparisons were made. Water-based exercise versus land-based exercise. Water-based exercise versus usual care

Result
The primary outcomes of quality of life and exacerbations leading to use of steroids were not reported by these studies.
For exacerbations leading to health center/hospital visits, uncertainty was wide because a very small number of events was reported (in a single study).

Conclusion
The small number of participants in the three included studies, the clinical and methodological heterogeneity observed and the high risk of bias .
Randomized controlled trials are needed to assess the efficacy and safety of water-based exercise for adults with asthma.

Method
42 individuals with moderate to very severe COPD, divided into 3 groups: Control Group (CG) Floor Group (FG) Aquatic Group (AG).
![Page 76: Aquatic exercise](https://reader036.vdocument.in/reader036/viewer/2022070512/589d82bc1a28ab69538b7057/html5/thumbnails/76.jpg)
Subjects were over 40 years of age From both sexes Gave informed written consent Clinically stable without periods of exacerbation
for at least 8 weeks. Nonsmokers or ex-smokers for at least 3 months. Free of lung infection and had medical supervision.

Spirometry.
Respiratory muscle strength (MIP and MEP).
The 6-Minute Walk Test (6MWT).
Medical Research Council (MRC).
BODE index
The St. George’s Respiratory Questionnaire (SGRQ).
All participants were assessed using:

Result
Pulmonary function : both (FG, AG) significantly improved FEV1 post-
intervention, while the CG exhibited a significant decrease in the FEV1/FVC
However, no significant difference was observed among the three groups after training
![Page 79: Aquatic exercise](https://reader036.vdocument.in/reader036/viewer/2022070512/589d82bc1a28ab69538b7057/html5/thumbnails/79.jpg)
Respiratory muscle strength: A statistical difference was observed in
MIP,MEP inthe training groups after the physical exercise program (FG, AG). No significant difference was recorded in the
CG post-intervention.

6MWT: There was no difference between groups for 6MWT
or for mean for dyspnea at rest and after the 6MWT. Only the FG showed a significant reduction in Rate of Perceived Exertion.
After training, the dyspnea index was significantly lower in the AG and higher in the CG.

SGRQ scores : There was no significant difference between
groups at the beginning of the study The FG showed improved quality of life
evidenced by the total score on the SGRQ

Conclusion
Results show that both forms of low-intensity physical exercise benefit patients with moderate and very severe COPD.
The AG exhibited additional benefits in physical ability, indicating a new therapeutic modality targeting patients with COPD.

UTM and LTM training are equally capable of improving aerobic fitness and body composition in physically inactive overweight individuals, but UTM training may induce increases in LBM.
Acute training period on an aquatic treadmill tended to increase select joint angular velocities and decrease arthritis related joint pain.
UTM may offer a good alternative to tradional LTM exercise in some cases only
