Why Exercise in Water?

The answer lies in three basic principles of water: hydrostatic pressure, buoyancy, and viscosity.

•Physical Properties of Water allow it to be a valuable tool in Physical Therapy
•Buoyancy: water counteracts gravity and helps to support the weight of the patient in a controlled fashion as the patient is immersed
•Viscosity: resists movement by means of friction, allowing strengthening and conditioning of an injury, while reducing the risk of further injury due to loss of balance
Hydrostatic pressure: produces forces perpendicular to body surfaces at every point, increasing kinesthetic (body motion or position) and proprioceptive (posture self-regulating) awareness in some patients.

Hydrotherapy/Aquatherapy in an underwater treadmill or custom therapy pool uses the natural properties of water, or the principles of relative density, buoyancy, hydrostatic pressure, surface tension, viscosity and resistance to achieve its therapeutic benefits in a safe environment. Exercising in
water can help reduce fatigue and pressure on joints, soothe aches, and help with balance. It can also improve mobility and flexibility, allowing patients to recover from surgery or an injury quicker, and experience greater quality of life and well-being.

• Provides resistance throughout the range of motion with 360°of resistance for all movements, providing a closed chain, hydrokinetic exercise
• Adjustable water depths for controlled weight-bearing exercises with less impact and stress on joints
• Higher outcomes with workouts in half the time as land based workouts
• Effective exercise for fitness, training and conditioning
• Adjustable treadmill speeds allow for more rigorous workouts
• Larger tank and doorway makes it ideal for athletes and bariatric patients
• Gait and range of motion can be monitored through viewing windows
• Multiple depth provide controlled buoyancy
• Warm water and buoyancy help relax muscles, reduce muscle stress and decrease impact on joints
• Cold water pools reduce swelling and increase blood flow.

Water is over 700 times as dense as air so a 30 minute workout in water is equal to a 60 minute workout on land.

You may be familiar with the benefits of Aquatherapy for injury treatment and rehabilitation. But did you also know that water can be used for healthy athletes, too? From enhanced workouts to optimized active recovery, it can prove to be fruitful in a variety of ways.


With the rise of sport specialization and decline in recreational play, overuse injuries have started to affect athletes of all ages and across multiple sports. According to the American Orthopedic Society for Sports Medicine, these injuries are the result of repetitive micro-trauma to the tendons, bones and joints. They can occur when the body is not given enough time or ability to recover between training sessions or when technique is not performed correctly.


Athletes, Sports Players and runners looking to stay in shape should be supplementing their land workouts with underwater running at least a few days a week. Because of the buoyancy, while running on an underwater treadmill, there is less pounding or shock placed on the joints, tendons, ligaments and muscles. When combined with the resistance of the water, this allows athletes to achieve a productive workout without feeling tired or beat up.


A study at Texas A&M University has shown that resistance training plus aquatic treadmill training can elicit greater gains in lean muscle mass than resistance training alone or even resistance training combined with land training. While it is often thought that cardiovascular training and resistance training cannot be accomplished simultaneously, the study shows it is possible.
The research showed that by doing a normal range of motion and mimicking sport activity in the pool, athletes actually worked harder to push through the water. This had a positive effect on the athletes’ entire bodies. This study, performed at Texas A&M University, has shown that running in the water leads to increased muscle strength in the legs, feet, hip flexors and extensors, core, and even stabilizing muscles throughout the body.


Because athletes using an underwater treadmill during training are running in an unloading environment, the pressure on their joints and muscles is reduced. Therefore, coaches are able to be more aggressive with other aspects of the athletes’ training, such as speed and strength work.
For starters, Aquatherapy can be great for a dynamic warm-up and to increase flexibility.:
Other types of athletes have seen conditioning and speed training benefits using the underwater treadmill as well.


Active recovery is a very valuable tool that can be used to improve performance. Sports medicine and performance specialists are starting to find that keeping muscles and joints moving after intense training days keeps athletes better equipped to handle subsequent workouts. AQUATHERAPY can be used as an effective and efficient active recovery technique.


Here are four benefits of Aquatherapy
1.The combination of hydrostatic pressure and active motion in the water leaves athletes feeling refreshed and rested, while at the same time feeling like they got an effective workout.
2.The use of the massage hose in the water can work to strip out lactic acid that has built up in the muscles after difficult workouts.
3.Athletes are ready for their next hard workout faster than if they just rested for a full day.
4.While recovering in the water, an athlete can efficiently rest muscles while also strengthening them and maintaining cardiovascular fitness.
Another reason to incorporate an underwater treadmill into training regimens is that athletes love it! Mentally and psychologically, it is refreshing. People feel rejuvenated and relaxed when they’re in the water, and it has a soothing, calming effect.

Hydrotherapy treatment involves the use of unique properties in water to achieve therapeutic benefits.

Hydrotherapy is a word most of us have heard but a lot of us probably don’t have a clear idea exactly what it is.

Essentially the word means ‘water as treatment/therapy’, thus it can mean lots of different things.

It has long been known that water has some very interesting properties particularly when it comes to the human body.

In ancient civilisations (think Egypt, Greece etc.) bathing in warm water and oils was used a method of relaxation and stress relief.

But it wasn’t until the 19th century that water started to be formally used for treatment by doctors and therapists.

Even then it was poorly understood why water was so helpful in curing pain and various ailments.

In this article we will aim to explain what beneficial effects of water we employ in hydrotherapy and what hydrotherapy means in a physiotherapy setting.

What is hydrotherapy?

Hydrotherapy, sometimes known as aquatic therapy, is a form of physiotherapy that uses water to warm the body and gently increase resistance. It is commonly prescribed by doctors for the treatment of a wide variety of conditions, including:

  • Arthritis
  • Back pain
  • Stress and Anxiety
  • Poor circulation
  • Muscle pain and inflammation
  • Headaches
  • Hip and joint replacement rehabilitation
  • Strokes and brain injuries

During a hydrotherapy session you’re not swimming, but rather performing a specific series of exercises. The pool is also heated to a warm 33-36°c in order to relax and soothe your muscles.

Other complementary treatments that can be used alongside hydrotherapy to alleviate the symptoms of arthritis may include massage, chiropractic adjustments, gentle exercise and adding fish oil to your diet.

Principles of Hydrotherapy

Hydrotherapy is unique as it can act as a treatment choice for either assistive or resistive force. There are unique principles of water that can make this possible:

Buoyancy: As per Archimede’s Principle of Buoyancy, a body immersed in a liquid experiences an upward force equal to the weight of the displaced liquid. This is why the body feels less weight in water than on land (this is also the principle behind hydrostatic weighing). The buoyancy of the water can assist or resist with the exercises of the extremities. In addition, changing the speed will either grade or change the exercise difficulty. In addition, the buoyancy of water is affected by postural alignment and the surface area immersed in the water.

Hydrostatic Pressure: A perpendicular pressure against the surface of the body exerted by water is called hydrostatic pressure. This pressure increases as the depth and density of the liquid increases. This is why a motion is performed more easily near the surface of the water than at greater depths.

Cohesion: Water molecules have a tendency to attract to each other. As a result, molecules are cohesive. This causes an increase in resistance to range of motion compared to that of the air.

Viscosity: Viscosity is an internal friction that directly depends on the speed of the liquid. In other words, the higher the speed, the higher the viscosity, and thus, the higher the resistance to the movement. Furthermore, the shape of the object (the body) also affects viscosity. A larger or more spread out object faces greater resistance to motion in the water.

Hydrotherapy Treatment Benefits

The two most beneficial mechanical effects of being in water are buoyancy and a little thing called hydrostatic pressure.

Buoyancy produces a feeling of partial weightlessness through your joints (you are only taking 10-15% of your bodyweight in chest high water) and can relieve a lot of pressure, which is particularly useful in arthritic joints or in people returning to walking after time in a cast or non-weight bearing.

It’s basically like taking a break from gravity for a while! Hydrostatic pressure is a property of water on solid objects, like your body!

Without going too in-depth some of the many benefits of this property include reducing swelling in injured joints, stimulating the immune system, improving cardiac function and blood flow and allowing participants to exercise more vigorously with less strain on muscles and the cardiovascular system.

Hopefully you’re starting to see the amazing benefits of exercising in warm water!

Hydrotherapy is useful in the treatment of:

  • Management of acute or chronic pain
  • Rehabilitation for pre- and post-joint replacement surgery
  • Relieve arthritis pain
  • Improve muscle flexibility
  • Improve range of motion
  • Improve strength via resistance training
  • Weight loss
  • Reduce muscle spasm
  • Fight fatigue
  • Aid in relaxation and lower stress levels

Additionally, hydrotherapy is a good alternative to vigorous exercise during pregnancy, and can help with labour pains during childbirth (water birth).


Hydrotherapy Contraindications

Hydrotherapy should be avoided in the following conditions:

  • Open wounds
  • Active infection
  • Altered sensation
  • Hydrophobia
  • Heat or cold intolerance
  • Poor balance
